Due to feedback inhibition, L-dopa causes a reduction in the body's own formation of L-dopa. So a point is reached where the drugs only work for periods of a few hours ("on" periods) which are sandwiched between longer interval during which the drugs are partially or completely ineffective ("off periods"). | |||

== Role of ND5 in pathophysiology of Parkinson disease == | |||
|topic=medicine | |||
"microheteroplasmic mutations in one of the mitochondrial complex I genes, ND5, were found to be sufficient to diagnose sporadic PD correctly in 27 out of 28 cases. While additional studies are needed, mitochondrial microheteroplasmic mutations may be the cause of the majority of PD cases." | |||

I believe this passage from the Toxins section strongly overstates the relative importance of ND5 mutations in particular, and microheteroplasmic mutations in general with respect to the pathophysiology of Parkinson disease. The only PubMed article I could find on ND5 mutations being used to classify PD cases versus controls is this one , and it mentioned correct classification of 15 of 16 samples, not the 27 out of 28 cited above. This means there were only 8 cases and 8 controls, which is a pretty small sample size, certainly not enough to make the sweeping statement, "mitochondrial microheteroplasmic mutations may be the cause of the majority of PD cases." ] 01:05, 16 February 2006 (UTC) | |||

*'''Support new image''' The current four images are low-quality, inconsistent, and unnecessarily clutter the infobox. More importantly, they fail to represent Parkinson's disease accurately, given its highly variable symptoms, which range from low blood pressure to cognitive decline. It's not even very clear what symptoms the current lead images are trying to illustrate, like the circled foot. These images violate ] as they are not genuinely representative. In contrast, a Lewy body—widely recognized as the hallmark biological feature of Parkinson's disease—provides a more accurate and universal depiction. Trying to accurately depict patients afflicted with a disease in the lead image is almost impossible and is not the standard on Misplaced Pages: see ], ], ], or other neurodegenerative diseases like ], the FA ], ], ], ], or ]. ~ ]] 02:03, 14 December 2024 (UTC) | |||

:The "Prevention" subsection has been around for quite some time, and is the standard on related articles like ], and is suggested per ]. I think that this objection might be rooted in a misunderstanding of the meaning of "prevention" in a medical context. It quite literally means "potential reduction of risk" (per the NIH: ""). Also, "Research on risk reduction" is a somewhat ungainly title, and don't essentially all of these subsections result from research? Should they all be titled "Research on X"?

Psychiatric disturbances are a common feature of Parkinson's disease (PD), which is a degenerative disorder defined by its characteristic movement abnormalities. Its management is optimal when PD is viewed as a neuropsychiatric disorder, because this encourages consideration of the motor deficits along with its psychiatric and cognitive aspects. This review addresses the diagnosis and treatment of the most common psychiatric disorders in PD, and provides an update of related clinical research, including studies on neurosurgical treatments. | |||

== Symptoms that cross over the physical into the cognitive and affective realms== | |||
The lists as constituted are poor vehicles for certain symptom sets: for example, speech-language problems. In PD, there are defects in articulation and breath support and voicing, but there are also problems with comprehension of complex syntax, with word finding, and with both expression and reception of prosody. Likewise vision and visual processing: the defects in vision are quite complex, seemingly a function of the combined effect of impaired attending, impaired gating of response, and slowed reaction time. The physical and cognitive and affective components of the disease are all snarled together, because the job of the pre-frontal cortex is precisely the integration of these kinds of inputs and outputs. The dysfunction observed in the prefrontal cortex when deprived of dopamine is subtle but radical: disconnects between physical stimulae and perception, between intention and action, between feelings and responses. At some point, these lists will not serve. ] 23:18, 17 January 2006 (UTC) | |||

dear afgriffith; you really did a super job. it's much clearer, more logical, and internally consistent. it also reads better. i appreciate that you left the language about patient rights and relationships, as that section above all others that i've contributed matters to me. i would like to ask you a question re: pd data, since i looked up your professional affiliation, and am very pleased to have someone with a connection to booth gardner contributing as you are: what is your best sense of both incidence and prevalence of dementia, by subpopulations, and also across the broadest historical study that you're aware of? i have found radically divergent estimations--30%, 40%, 40-80%. it strikes me that there mu[st be some real bias in the data, because people who are doing badly are more frequently lost to follow-up than are indvidiausl who are doing well. barb | |||
Thanks, Barb. I'm working on this article section by section, mostly trying to reorganize without completely overwriting what has gone before, unless it's inaccurate or outdated. With respect to your question about dementia, I think Heiko Braak's work on Parkinson disease pathology is most illuminating. He published an article in Neurology linking incidence of dementia to severity of pathology. I'm going to be working on the pathology/pathophysiology section next, and will have more to say on that subject. ] 19:26, 20 February 2006 (UTC) | |||
Dear A: I'd like to use your first name some variant of it, but don't wish to be presumtuous. may i use your your/ first initial? i'd also ask if you'd take a look at both this article and the wikipedia dementia article, in light of a citation i just came across: (http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=12567332&query_hl=21&itool=pubmed_docsum) "making it the most common cause of degenerative dementia after AD" and also: (http://jnnp.bmjjournals.com/cgi/content/extract/76/7/903) Patients with Parkinson’s disease (PD) have a significant risk of developing dementia in the course of their illness. Cross sectional studies suggest a dementia prevalence rate of 30% to 40%.1 Longitudinal studies indicate that the cumulative frequency of dementia in patients with PD is 60% to 80%.1 The risk of dementia for individuals with PD is approximately six fold greater than that of age matched controls. | |||

To current editors - I think both Griffith & Davids are no longer editting this, however they raise an interesting point. Coupla years ago I did a bit of research & susbequently submitted a grant ptoposal (turned down, sob!) with a friend who's a psychometrician because we found that the accounts of dementia in PD were simply clinical observation, no comparisons. We thought, well for heavens sake!, people that age tend to get demented anyway. The question was (and still is) do people with PD get dementia at a different rate and in a different fashion than other people their age.

==Parkinson's speech== | |||
I didn't see anything about Parkinson's speech in this article. That isn't my speciality but I regularly get calls from PD patients whose speech has been affected. Judging from these individuals, speech symptoms are one of the most devastating effects of PD, so this article should say something about Parkinson's speech. I've written a short article about Parkinson's speech in . What I wrote is too short to be a WikiBook, but the subject is too big for a Misplaced Pages article. I'm hoping that someone with more expertise will expand my WikiBook article. I also added a link at the bottom of the Misplaced Pages article to my WikiBooks article, and a link to .] 18:11, 1 March 2006 (UTC) | |||
== Pathology section == | |||
I'm going to add to the mix my (probably) unwanted request to have in the pathology section something about the physiology of the diseas e.g. how the degenration of dopaminergic neurons causes the motor disorders. (Basal ganglia, anyone?). | |||
Yeah, and to ensure the universal hatred of me, four times the exact same link about the already well (perhaps even too) detailed biochemistry is definitely an overkill... --] 17:08, 10 May 2006 (UTC) | |||
Understood the idea and actually fixed the links to point straight to the correspondings posts rather than the first one. Maybe that way it does not seem so repetitive. Still think it's overkill though.--] 18:07, 10 May 2006 (UTC) | |||
: Please refer to the ]. The only aspect that this doesn't fully give the "how to" for is that the part of the ] after the # is the bookmark in the ] code of the target page. The "clever" changes made by user:80.221.29.185 are just implementations of this general wiki format for external links. In his/her wisdom, he/she obviously grasped that in their original format, because all your citations looked identical, they gave an appearance of being something you had not intended, and which I had the temerity to question. Now that he/she has amended these citations such that they now all appear as different "link names", this has had the benefit of being an incremental improvement to the pathology section. To obtain each #bookmark simply required him/her to follow the original links, find the part of the page you were referring to, examine the HTML code, and constuct the external link complete with the bookmark accordingly. One might almost say that this could have been done without more than a rudimentary knowledge of biochemistry, as long as each bookmark name matched the topic you had described. ] 19:36, 13 May 2006 (UTC) | |||

You know just reading this page again, I think it's insane that there's a whole page about these utterly unfounded theories about "toxins" before you get to a brief mention of the frontline, highly effective treatment for PD, being the Dopamine agonists! I might even go so far as to suggest there is a new page called "hypotheses for the pathogenesis of Parkinson's Disease" in which these theories can be vaguely alluded to, but for now I think there is far too much emphasis placed on these scatty paragraphs. If the majority of other editors are in agreement I will begin the pruning. --] 18:09, 19 June 2006 (UTC) | |||

This article is currently too long. There is some very useful stuff in here but it's not the sort of thing that's directly relevant to someone looking it up for the first time. There are also glaring omissions such as the diagnostic process. I am trying my best to chunk off new articles in as rational a fashion as possible in accordance with these two guidelines: | |||

==Major Revision - Principles== | |||
I'm going to try to outline my rationale for a major revision of the article ]. | |||
1. The article is too long. (]). | |||
2. The article goes in to too much detail about the biochemistry of Parkinson's, which whilst informative and valid is too complex for the vast majority of readers. | |||
In particular please consider this from ]: | |||
"Since Misplaced Pages is not divided into a macropaedia, micropaedia, and concise versions like Encyclopaedia Britannica is, we must serve all three user types in the same encyclopedia. Summary style is based on the premise that information about a topic should not all be contained in a single article since different readers have different needs; | |||
* many readers need just a quick summary of the topic's most important points (lead section), | |||
* others need a moderate amount of info on the topic's more important points (a set of multi-paragraph sections), and | |||
* some readers need a lot of detail on one or more aspects of the topic (links to full-sized separate articles)." | |||
3. There are other articles about neurological disease which are better. IMHO these include: | |||
* ] | |||
* ] | |||
* ] | |||
* ] | |||
I don't see any reason why we can't make PD as good if not better and make it a featured article. | |||
4. There are several people working on the article that are expert in various fields. For instance it would seem Profsnow is an epidemiologist, General Tojo is a biochemist, I'm a neuropsychologist. Therefore I would suggest that for now we stick firmly within our areas of expertise. We should find a neurologist to take an overview of the introduction, diagnosis, prognosis sections. | |||
: We've got a neurologist on board already, user AFGriffithMD. He's in on discussions further up the page. --] 16:04, 27 June 2006 (UTC) | |||
5. Until these principles are agreed I don't think anyone should make anymore changes to the page. | |||
--] 10:13, 21 June 2006 (UTC) | |||
:I support a revision, but please start by reducing unsourced nonsense. At the moment whole sections are unreferenced or use the p4.forumforfree.com site as sources. This is not acceptable. Scientific review articles are the ideal source, not primary studies (the impact of which cannot be judged). Please use your judgement in moving unsupported material to the talkpage, always leaving clear and polite ]. | |||
:At present we have no Misplaced Pages neurologist, so unless one of you can recruit one we'll have to make do without. | |||
:I would like to propose that blind reverts are not performed on this article. Rather, a contentious edit can be discussed on this very talkpage, and reverted if other editors agree it was not appropriate. | |||
:All editors please familiarise yourself with cite.php and make it a habit to cite peer-reviewed academic studies rather than URLs on potentially unreliable websites. ] | ] 10:43, 21 June 2006 (UTC) | |||
Prognosis | |||
This section has litle to do with the realities of what occurs in most people with Parkinson's Disease. The first section claims increased mortality, but even the second section nullifies it. It then misrepresents what usually occurs by implying that most people with PD die of pneumonia. Very few do, and the biochemistry of pneumonia has nothing to do with PD biochemistry. In disorders such as HIV it is reelvant to describe what usually eventually occurs. However, in PD there is no usual. The prognosis section is misleading, and of no practical use to anyone with PD. | |||
General Tojo from what I understand you are a biochemist. Not a patient. Not an advocate. Not a clinican. Therefore on what basis can you put yourself forward as a representative of "anyone with PD"?. Frankly I'm not finding your edits to be helpful. --] 17:49, 21 June 2006 (UTC) | |||
It is obvious that we're talking here about dementia as part of Parkinson's. Also, they are both fairly common and it's quite possible that someone with Parkinson's will also develop dementia (James + Alois). All this is not reason to remove the ''whole'' paragraph. I'm pleased to see that General Tojo has now agreed to only remove ''part'' of the "prognosis" section. However, I would still like to see some data on the actual odds of death for PD patients. The argument that PD does not ''directly'' cause death is quite irrelevant: it predisposes for lethal conditions. Heart attacks do not cause death - only cardiac arrest does. ] | ] 19:56, 21 June 2006 (UTC) | |||
==Once more unto the breach...== | |||
Right, that's better. OK what do you say we take up JFDWolff's suggestion about evidence? We could for instance start with adding and updating lines with the best evidence e.g. Cochrane reviews, then lit reviews, then big studies (esp RCTs), then small studies, then case series and then case reports. | |||

==Cardinal symptoms== | |||
Paul, - first, because PD is a disease with a long latency and development, with patients able to ignore symptoms or ascribe them to old age, presentation is highly variable and the collection of symptoms people will have through the course of their disease is likewise variable. Second, in nosology in western medicine we define diseases by three main ways: by the cause (eg. Tuberculosis or asbestosis), by the anatomic site affected (almost any cancer, or by the symptoms (Parkinson's, Depression, and tuberculosis before we knew about the bug). People can be sickened by a rhinovirus, and have differing constellations of symptoms - it does not negate the concept of 'common cold'. Just so, varying symptoms of Parkinson's patients does not negate that disease concept. One could argue that more successfully with something like "fibromyalgia" or "chronic fatigue syndrome", though. --] 19:42, 30 June 2006 (UTC) | |||

== Pathophysiology and epidemiology sections == | |||
a) Terminology | |||
When people refer to Parkinson's disease, it seems they are usually referring to the idiopathic disease first described by Dr. Parkinson. There are other less common diseases that are symptomatically similar to idiopathic Parkinson's, but either present with a few different symptoms, or have a known cause (that means they're not really idiopathic anymore, right?). | |||
I think it's confusing to refer to these Parkinson's-like diseases as Parkinson's. | |||
I have heard various researchers propose using the term "parkinsonism" when referring to diseases similar, but not identical, to idiopathic Parkinson's. (The "Related Diseases" section seems to allude to that.) | |||
Perhaps this article could do something similar with the terminology? | |||
A terminology clarification would mostly help the pathophysiology section. As currently written, I think it is hard to tell which of the various listed genotypes, toxins, traumas, or drugs are causes of idiopathic Parkinson's, and which are causes of different diseases that present with symptoms of parkinsonism. | |||
b) Unilateral Causes vs. Part of Multifactorial Disease | |||
Which of the aforementioned mentioned causes will induce parkinsonism all by themselves, and which are associated with the disease without causing it singlehandedly? | |||
(see ). | |||
::I could be mistaken, but except possibly for acute PD and MPTP, I don't think there are any unilateral causes. Here's a worthwhile article on causation . I adhere mostly to the Rothman model of causation, with a little Popper thrown in (we were all mad for Popper about 20 years ago). --] 15:43, 26 June 2006 (UTC) | |||
:::That's what I thought ... I think this should be discussed in the pathophysiology section, because it doesn't really read that way now. I actually rather agree with ]'s earlier opinion on that matter (see the discussion ...) --] 17:42, 26 June 2006 (UTC) | |||
c) More Epidemiology | |||
Speaking of these causes, I've heard of several twins studies and of a career study, the results of which would enhance the epidemiology section. Is there an epidemiology-saavy person out there? | |||
] 09:04, 25 June 2006 (UTC) | |||
:Hi GeekPhilospher, my understanding is this: If it looks like Parkinson's but it's not idiopathic (e.g. resulting for neuroleptics, MPTP exposure, brain damage) then it is parkinsonism. If it's MSA or PSP then it's a Parkinson's plus syndrome. I agree that things have got a bit confusing. There is a ] article, I don't know if you'd like to weave those together. | |||
:And we do have an epidemiologist knocking around, ProfSnow, who should be back from holiday tomorrow. Twin studies are important, as are the suggestions of a premorbid low-sensation-seeking personality. Cheers, --] 09:17, 25 June 2006 (UTC) | |||
::sounds good ... I will see what I can do incorporating that into the pathophysiology section. Speaking of, is "pathophysiology" the best name for that section? --] 12:27, 25 June 2006 (UTC) | |||
::And I am back from the Society for Epidemiologic Research meeting in Seattle - and it was a very nice holiday, thank you. Twin studies and career studies I'm not sure on but can find out. Off the top of my head I'd bet Carlie Tanner did any twin studies. As far as careers go, we're all pretty tightly focused on farming & have been ever since Bill Langston found the MPTP outbreak, and even before - maybe since Barbeau? I will put my descriptive epidemiology, including incidence, section back as soon as things are open again, or in an appropriate sub-article. I'd frankly rather have epidemiology separate from pathophys, if you all don't mind. --] 15:35, 26 June 2006 (UTC) | |||

] and Wilson's disease have been included as part of the Parkinson-plus diseases. However, while they may be associated with parkinsonism, my (naive) sense is that these are distinct clinical entities and would not be considered a Parkinson-plus disease like Shy-Drager syndrome. ] 12:16, 27 June 2006 (UTC) | |||
: I think we're on the same page. These disorders which have similar symptoms like Wilson's disease, etc. would probably be better off included under ] rather than under Parkinson's disease. Or alternatively, perhaps a section about differential diagnosis, so that the distinction can be more explicit. ] 13:02, 27 June 2006 (UTC) | |||
::I like the differential diagnosis section with pointers very much, Andrew. Familial tremor is, of course, far and away the most common miss, probably simply because it's common. So perhaps we should think in terms of ''rate'' of misdiagnosis for a given disease, thereby correcting for the rarity. When you have diseases such as PD that are defined and diagnosed solely by symptoms that vary from person to person and even for hour to hour, both clinical diagnosis and research can be tricky. --] 15:24, 27 June 2006 (UTC) | |||
:::I like the idea of a "differential diagnosis" section too. The "diagnosis" section does need plumping up too, maybe on average time to diagnosis or average symptom duration? Other things to include or link off to new articles might be dopamine challenge, DAT-scan, and of course progression. i.e. Although many people may be misdiagnosed at any one particular timepoint, diagnoses can be revised if a period of time has past in which progression is at an unusual rate (either too fast or too slow). --] 16:42, 27 June 2006 (UTC) | |||
:::The time to diagnosis question is a good one. I've done some work on that and on time from initial diagnosis to final, correct diagnosis assuming the initial dx wasn't right. PD patients typically do not attach much significance to their initial symptoms at the time, but once diagnosed they realize that <u>that</u> symptom on that day was the (clinical) start. I don't recall details, but the work I did showed that time to dx was shorter for women, of course. --] 19:49, 30 June 2006 (UTC) | |||

== American Academy of Neurology == | |||
Recently a colleague coincidentally emailed me an article from Neurology about PD. It was one of four reports on Parkinson's disease this year by the Quality Standards Subcommittee of the American Academy of Neurology. They were made through systematic review of the current literature by a committee of movement disorder specialists and general neurologists. | |||
See Neurology 66(7):966-1002 ... it's free to download at http://www.neurology.org/content/vol66/issue7/ | |||
Anyway, I think the 4 articles outline quite well the important questions and the answers currently known regarding diagnosis and treatment of PD, so I'm copying the conclusions from their abstracts: | |||
"Diagnosis and prognosis of new onset Parkinson disease" (Neurology 66:968-975) | |||
1. Early falls, poor response to levodopa, symmetry of motor manifestations, lack of tremor, and early autonomic dysfunction are probably useful in distinguishing other parkinsonian syndromes from Parkinson disease (PD). | |||
2. Levodopa or apomorphine challenge and olfactory testing are probably useful in distinguishing PD from other parkinsonian syndromes. | |||
3. Predictive factors for faster disease progression (more rapid motor progression, nursing home placement, and shorter survival time) include older age at onset of PD, associated comorbidities, presentation with rigidity and bradykinesia, and decreased dopamine responsiveness. | |||
"Neuroprotective strategies and alternative therapies for Parkinson disease" (Neurology 66:976-982) | |||
1. Levodopa does not appear to accelerate disease progression. | |||
2. No treatment has been shown to be neuroprotective. | |||
3. There is no evidence that vitamin or food additives can improve motor function in PD. | |||
4. Exercise may be helpful in improving motor function. | |||
5. Speech therapy may be helpful in improving speech volume. | |||
6. No manual therapy has been shown to be helpful in the treatment of motor symptoms, although studies in this area are limited. | |||
"Treatment of Parkinson disease with motor fluctuations and dyskinesia" (Neurology 66:983-995) | |||
1. Entacapone and rasagiline should be offered to reduce off time (Level A). Pergolide, pramipexole, ropinirole, and tolcapone should be considered to reduce off time (Level B). Apomorphine, cabergoline, and selegiline may be considered to reduce off time (Level C). | |||
2. The available evidence does not establish superiority of one medicine over another in reducing off time (Level B). Sustained release carbidopa/levodopa and bromocriptine may be disregarded to reduce off time (Level C). | |||
3. Amantadine may be considered to reduce dyskinesia (Level C). | |||
4. Deep brain stimulation of the subthalamic nucleus (STN) may be considered to improve motor function and reduce off time, dyskinesia, and medication usage (Level C). There is insufficient evidence to support or refute the efficacy of deep brain stimulation (DBS) of the globus pallidus interna (GPi) or ventral intermediate (VIM) nucleus of the thalamus in reducing off time, dyskinesia, or medication usage, or to improve motor function. | |||
5. Preoperative response to levodopa predicts better outcome after DBS of the STN (Level B). | |||
"Evaluation and treatment of depression, psychosis, and dementia in Parkinson disease" (Neurology 66:996-1002) | |||
Screening tools are available for depression and dementia in patients with PD, but more specific validated tools are needed. There are no widely used, validated tools for psychosis screening in Parkinson disease (PD). | |||
The Beck Depression Inventory-I, Hamilton Depression Rating Scale, and Montgomery Asberg Depression Rating Scale should be considered to screen for depression in PD (Level B). The Mini-Mental State Examination and the Cambridge Cognitive Examination should be considered to screen for dementia in PD (Level B). | |||
Amitriptyline may be considered to treat depression in PD without dementia (Level C). | |||
Cholinesterase inhibitors are effective treatments for dementia in PD, but improvement is modest and motor side effects may occur. | |||
For psychosis in PD, clozapine should be considered (Level B), quetiapine may be considered (Level C), but olanzapine should not be considered (Level B). | |||
Hope that's of interest (despite the length). I think it may help with cleaning up the PD article. | |||
--] 03:09, 29 June 2006 (UTC) | |||
:Very nice; thank you. To my mind, we need a good study of the incidence of dementia in PD patients compared with general population of that age. I put in a proposal to the feds a coupla years back to do that, and included stuff about developing a dementia instrument specific to PD. The reviewers thought we were biting off too much. I should go back in on that, though - I think it still hasn't been done, and I have the credibility in the field. What do you guys think? The underlying alternate hypothesis is that dementia is diagnosed more often in PD patients because they're seen more often by docs and because docs are keyed to look for it. --] 04:31, 29 June 2006 (UTC) | |||

== Toxins == | |||
Just to clarify, my understanding is that reactions to toxins like cyanide produce an acute onset syndrome resembling Parkinson's disease. But they do not produce Parkinson's. Is that correct? So should these toxins be listed under Parkinsonism rather than Parkinson's disease? --] 17:31, 10 July 2006 (UTC) | |||
http://www.postgradmed.com/issues/1999/07_99/conley.htm | |||
: Agreed. I tried clarifying that with a sentence in the beginning, but perhaps this needs to be stated more explicitly. ] 17:40, 10 July 2006 (UTC) | |||
The distinction I've seen made clinically is this; | |||
* Parkinsonism is a syndrome of symptoms resembling idiopathic PD which usually does not usually respond to DA treatment such as sinemet or DA agonists. It can be caused by brain damage, vascular infarcts, and toxins. Sometimes it is progressive, sometimes not. In the case of toxicity, it may be reversible following removal of the toxin. The most obvious case I have heard of is poisoning by antipsychotic medication leading to an acute but reversible parkinsonism. Other toxic causes may be irreversible. | |||
* Parkinson's disease is progressive and responds to dopamine therapy and is the main clinical syndrome we all know and love. | |||
* Parkinson's Plus refers to PSP and MSA which are important to identify for the reason that they can be more aggressive and in the case of PSP have greater ocular and cognitive involvement. --] 19:04, 10 July 2006 (UTC) | |||
:Parkinson Plus is clinically highly relevant, e.g. when there is a need to treat autonomic phenomena in MSA with autonomic features (formerly Shy-Drager). Toxins are certainly relevant, and if there has been rapid clinical deterioration a clinician may suspect carbon monoxide poisoning. Other toxicities are not generally suspected unless there are obvious clues (e.g. plethora and/or polycythemia in chronic HbCO). This is one of the reasons why in the UK the diagnosis of PD is now left to neurologists rather than general physicians. ] | ] 20:38, 10 July 2006 (UTC) | |||
== Some ideas for parts that could be split off into new pages == | |||
Just ideas to cut down on article size and varying levels of detail, let's discuss before doing anything. | |||
* http://en.wikipedia.org/Parkinson%27s_disease#Symptoms - These could be summarised more briefly on the PD page with the main articles being ] and ] which would allow more space for explanation | |||
* http://en.wikipedia.org/Parkinson%27s_disease#Pathology - The level of detail here might be too much for the overview article. Suggest creating new article for full biochemistry. | |||

== Differential == | |||
I removed this list of differential diagnoses: | |||
:Diseases that are in the differential for Parkinson's disease include: | |||
:* Cerebellar thoracic outlet syndrome | |||
:* ] | |||
:* Vascular parkinsonism | |||
:* ] | |||
:* ] | |||
:* ] | |||
:* ] | |||
It is unreferenced, it has come from nowhere, and doesn't explain the relationship. Antiphospholipid syndrome is not associated with any extrapyramidal phenomena in the vast majority of cases. Essential tremor is usually ruled out early-on on clinical grounds. Wilson's disease should be mentioned, but not in such a random fashion (young PD patients should have copper studies, though). | |||
Can we get a list from a reliable medical textbook, instead of someone's ]? ] | ] 07:33, 12 July 2006 (UTC) | |||
All of the above are well known to cause symptoms some of which can coincide with those of Parkinson's Disease. A link was previously provided to the Parkinsonism page of the The Parkinson's Disease Forum. They are also linked to pages on Misplaced Pages where more information is given. So if somebody wants to expand on this section with additional brief inormation for each disorder the links and information are available for them to do this. | |||
: I agree with JFW that a laundry list of diseases that may resemble Parkinson's disease is not necessarily that useful (e.g. echoing again antiphospholipid antibody syndrome, which is quite distinct diagnostically and clinically). ] 12:13, 12 July 2006 (UTC) | |||
: I just read the article describing three patients with movement disorders. All of these patients underwent intensive investigation, since their symptoms were more than just parkinsonism (apraxia, etc.). It doesn't seem like these patients were given a primary diagnosis of Parkinson's disease, the concern that you raised. It seems a bit of an overcall then to include APA in the differential. ] 12:58, 12 July 2006 (UTC) | |||
==A cure for Parkinson's disease== | |||
1. Everyone who has a PhD has expertise in that subject ??? Be serious. | |||
He never said that - you're setting up a strawman. --] 22:25, 12 July 2006 (UTC) | |||
Well then it's not a personal attack as you claimed when I point out that PhD's mean nothing. | |||
I assume you don't have one? The bare minimum qualification as a scientist? --] 07:20, 13 July 2006 (UTC) | |||
2. None of those people he referred to have ever cured anyone of Parkinson's Disease is a very relevant fact. | |||
:Have you ever cured anyone of PD? Last I heard it was an incurable disease. --] 22:25, 12 July 2006 (UTC) | |||
: I'd like to know of the cure for Parkinson's too! ] 00:33, 13 July 2006 (UTC) | |||
I have seen some people rid their symptoms altogether, and have seen many more continuously reduce their symptoms. That is why one of the largest and most prestigious hospitals in Britain is very enthusiastically arranging a full scale clinical trial to prove this formally and on a large scale. The methods Wimpys so called experts support could never cure anyone because they are so scientifically unsound from the outset. | |||
: Could you provide additional detail about this trial? ] 00:33, 13 July 2006 (UTC) | |||
: Just because a trial is being discussed it doesn't mean it will happen. Even if it does it does not mean it will work. I've seen major hospitals do trials of quack substances before just out of curiosity. Also if there's money involved they'll do quite a lot of things. | |||
:I'm interested in the fact that when I use an appeal to authority (working at a large and prestigious hospital) you denigrate it, whereas when you're trying to persuade us, you want us to know that the trial is going on at another "of the largest and most prestigious hospitals in Britain". Or is it only institutions which you deem to be large and prestigious? --] 07:20, 13 July 2006 (UTC) | |||
3. Neurologists do not study biochemitsry. It is simply not part of a medical degree courses. | |||
:Actually, they do and it is. and in any case, so what? Biochemists don't study neurophysiology, so shouldn't be expounding on neurologic diseases. --] 22:25, 12 July 2006 (UTC) | |||
:Yup, all the neurologists I know are quite handy with their biochemistry actually. It sort of helps when you're prescribing drugs, but you've never done that.--] 07:20, 13 July 2006 (UTC) | |||
: Actually, the formation of dopamine is studied in medical school, at least in the U.S. ] 00:33, 13 July 2006 (UTC) | |||
:Likewise in UK ] <sup> ] </sup> 00:37, 13 July 2006 (UTC) | |||
:I know it is at GKT. --] 07:20, 13 July 2006 (UTC) | |||
:: Thanks for the information. I'm not familiar with how clinical trials are done in the UK, but in the U.S. they're generally registered at http://clinicaltrials.gov/. Is there a similar reporting mechanism for this trial? I'm surprised that the full formulation has not yet been disclosed if it's already undergoing a clinical trial. ] 12:15, 13 July 2006 (UTC) | |||
:Sorry Keith, I do apologise. I can see now where this has all sprung up from, it's a great misunderstanding. | |||
:I had incorrectly assumed that because you used the language of a scientist and spoke with such authority that you might actually be one. But if you don't have a PhD (even though I have three) then no wonder you're unable to work within the field (although I have all my adult life), publish peer-reviewed articles (although I've been published in seven languages in over 150 countries), obtain grant funding (even though I have), or collaborate with others (even though I am doing so continuously, and have done so for many years). We've all been addressing you as a fellow scientist (even though you're not one yourself) when in reality you are a layman (even though I'm not). I'm very sorry for the confusion this must have caused you, we will all endeavour to explain the way of the world in simpler terms from here on. --] 14:02, 13 July 2006 (UTC) | |||
: So let me summarise then - there is no current available cure for Parkinson’s, but you are involved in a study that hopes to change this. Whilst I wish the study luck, there is therefore, as yet, no published peer-reviewed paper (]) to back up the current accepted wisdom that Parkinson’s is incurable - assertions to the contrary is, for now, just personal opinion/speculation and not acceptable under ] policy. If and when the study you are involved with is published, then medical knowledge will have advanced and wikipedia will I am sure reflect this (with suitable citations provided to verify). | |||
== Tyramine containing foods == | |||
I've included the comment about tyramine-containing foods being okay with MAO-B inhibitors in order to distinguish it from other MAO inhibitors that are used for depression, e.g. ]. I imagine this is practically relevant information that should be kept in the article. (I'm not saying that tyramine-containing foods are a treatment for Parkinson's disease!) ] 12:17, 13 July 2006 (UTC) | |||
== Incidence rates == | |||
True Parkinson's disease is global and Misplaced Pages is global. However, I think it's worthwhile to include the incidence rates, even if it's specific to one area. The information is factual and referenced. Instead of not including it at all, why not add information about incidence rates globally? ] 18:33, 13 July 2006 (UTC) | |||
Incidence and prevalence vary globally for many reasons, primary among them being diagnostic and ascertainment differences, with risk factor and true rate differences adding to that variation. Incidence rates are ascertained by counting all cases of disease arising in a defined population over a defined period of time. There are very few places in the world where that sort of study is practical Notice that I did include European studies. There are very few Asian PD epidemiologists, and those are mostly focused on risk factor epidemiology rather than descriptive epidemiology, although I have reviewed a prevalence study from Korea. The rates from northern California are solid because they come from a closed, well-defined population (Kaiser Permanente) with systematic surveillance mechanisms and excellent diagnostic standards (Dr. Caroline Tanner). --] 19:24, 13 July 2006 (UTC) | |||
Incidence of ] per 100,000 per year in California | |||
Incidence of ]per 100,000 per year in Spain | |||
Limited quoting of incidence rates is useful - either it highlights a need for the WP article to have a more rounded review of reported results added, or if there is a paucity of studies from which cite then that in itself is notable and should be commented upon. Likewise if there is great discrepency of reported incidence rates, this may indicate poor studies, different criteria for the studies (either diagnositic or inclusion criteria eg prospective or retrospective) or truely indicate that there might be genetic or environment variability. None of these suggest removing data just for being incomplete - WP after all specifically allows incomplete articles, namely stubs, which are tagged as such until they can be expanded into a full articles - no one goes about deleting stubs just for being incomplete. ] <sup> ] </sup> 00:00, 14 July 2006 (UTC) | |||
::See, David, here's the thing. What you're really after with descriptive epi is etiological hypotheses. As you know, prevalence studies are limited in their value for that because they're too prone to bias. Incidence studies are sounder methodologically, but tougher to do (ie expensive) because you have to count all new cases in a defined population over time. And after you've done the study, what do you have? Well, some interesting rates and maybe some ideas on who gets more/less of the diease. But with Parkinson's, we think we've already got some pretty good ideas and what might be causing it, i.e. the farming chemicals, so why bother with the incidence studies - makes much more sense (and more likely to be funded) to jump right into the hypothesis testing studies, case-control design (if you're Karen Semchuk or Walter Rocca) or even cohort studies (if you're Alberto Ascherio and have access to the Nurses' Health Study). Which means the next section I oughta write up is the risk factor epidemiology section. I'm not convinced farming chemicals are going to be the big payoff everyone thought after Bill Langston found that MPTP outbreak back in what, 1986? I think there might be something else about farming. But we shall see. --] 14:44, 14 July 2006 (UTC) | |||
::: Thanks for the points raised. My posting was mainly counter-arguement to DiamondPlus objecting to any such incidence info, if not a complete world-picture. You make some good points, but if ''"I'm not convinced farming chemicals are going to be the big payoff everyone thought "'' then perhaps ''"we think we've already got some pretty good ideas and what might be causing it"'' is not the case (hence a need appropriate studies). Even if hypothesis testing studies prove the cause, the cause might not be eliminatable: if it proved (for sake of discussion) due to nitrogenous toxins from meat-eating, then are people really going to fully stop eating meat (issues also of risks iron deficiency) - and I still would like to know the incidence rates (clearly 100% of meat eaters do not go on to get PD, if 10% risk it might affect my dietary habits, but at 0.1% I might decide to ignore the risk). Similarly incidence rates are useful in health planning. Leaving aside reduced incidence rates if the causative factors are identified and eliminated, if 2% of the current population have already been exposed to a causative factor and will inevitably now get PD at some point, then this will be a major health care service requirement, yet if incidence rates are just 0.1% then provision needs are relatively small compared to other diseases. Even if cause of PD is found and 100% prevention ensues, I would still like to know how much of a historical imposition this was to healthcare/social-services/individuals (in increasing importance) :-) ] <sup> ] </sup> 15:39, 14 July 2006 (UTC) | |||
::::: Yup, good counter-points. Being an etiologic epidemiologist, the health services/public health impact tends to be something that occurs to me later rather than earlier, but of course for someplace like Nebraska, with a proportinally large old population, it's a serious matter. The town of Grand Island, for instance, in the late 90s underwent a boom in old people because some very nice supported living and nursing homes were built, drawing lots of people from the surrounding counties (nobody lives in those counties anyway), so of course the Nebrasks Parkinson's registry observed a rise in prevalence in Grand Island. At the same time, however, an obnoxious neurologist in north-eastern Nebraska steadfastly refuses to report his PD patients to the registry, so of course prevalence seems low there. --] 16:01, 14 July 2006 (UTC) | |||
==Protection?== | |||
While the article is protected (which is likely to last a few weeks), we should discuss which sections of this important article need improvements, and in what way. I think the "toxins" section, despite General Tojo's insistence, occupies way too much space and should be reduced to the most established toxic causes (e.g. MTPT, HbCO). There may be room for a subarticle if all material is found to be highly-relevant (]). ] | ] 09:50, 14 July 2006 (UTC) | |||
: Agree, it needs to be debulked or spun off into a subarticle. Right now, it reads like a laundry list. I'm surprised that H<sub>2</sub>O or O<sub>2</sub> aren't listed. ] 12:27, 14 July 2006 (UTC) | |||
:You know what? I was looking through the older versions of the article, and up till Feb 2006 or so, as Barb Davids finished up her contributions, this was a pretty darn good page. Needed some epidemiology, of course, but it was pretty good. --] 19:00, 14 July 2006 (UTC) | |||
:Agreed. Please note that I created two other subpages, ] and ] that we can use to go into more detail. A postdoc just started in our team who specialises in hallucinations and I'd really like her to add more on non-motor symptoms. There simply isn't need for such detail on the main page though. If everyone's happy with the drug table I've put on the talk page (or would like to add to it) then I think we should have a ] as Jfdwolff has suggested in the past. --] 21:18, 14 July 2006 (UTC) | |||
I reduced to semi-protection, as Tojo uses newer socks ] ] 23:26, 15 July 2006 (UTC) | |||
Re-protection please. --] 11:54, 16 July 2006 (UTC) | |||
'''I agree with that because PaulWicks keeps vandalising the page. When did he ever actualy add anything useful -never. If you check his last 100 "contributions" you will find that it consists entirely of reverts, complaints, blocking and criticisms. He is entirely negative by nature, and gets in the way of genuine contributors. He was still a student last year. He knows next to nothing. Only he knows what he's doing here.''' --] 11:58, 16 July 2006 (UTC) | |||
== Great idea - that'll really help. General Tojo == | |||
==Archive?== | |||
I'd like to archive the older parts of this talk page. Is there a date before which the discussions are no longer active? ] <sup>]</sup> 18:06, 14 July 2006 (UTC) | |||
Is the size a problem? I think most stuff before Jan 2006 is no longer active, since those earlier contributors - like BLDavids - aren't around anymore. A shame, but part of the size problem is Bridgeman's proliferative posting. --] 18:35, 14 July 2006 (UTC) | |||
:It's not so long as to be a problem, if it's useful to keep it. I'll leave it alone for now. ] <sup>]</sup> 19:52, 14 July 2006 (UTC) | |||
::Why not just archive all that is GT-related and leave the actual discussions up? Also please leave my drug table there! --] 21:20, 14 July 2006 (UTC) | |||
:If you want I'll try to ] the page, removing GT's remarks and all the replies to them. They'll still be in the history if anyone wants to refer to them. I'll be sure and leave the drug table. I'll try to do it tomorrow if no one objects. ] <sup>]</sup> 21:29, 14 July 2006 (UTC) | |||

:::Some form of archiving is required - this page takes ages to load on my slow dial-up connection (almost makes me dread the boredom of waiting to view the latest postings here)- I agree in first instance archive off GTs trolling and then lets see if/where we wish to archive older historical discussion threads. ] <sup> ] </sup> 23:47, 14 July 2006 (UTC) | |||
I have finished refactoring the page. I tried to remove all the extraneous conversations, and in a few cases summarized people's words. Please correct any mistakes I made. The un-refactored version will of course be available in the history. ] <sup>]</sup> 13:14, 15 July 2006 (UTC) | |||

RfC: Should the four lead images be replaced?
- The following discussion is an archived record of a request for comment. Please do not modify it. No further edits should be made to this discussion. A summary of the conclusions reached follows.
Should the four images currently used in the infobox be replaced with this one of a Lewy body below? ~ HAL333 02:03, 14 December 2024 (UTC)
Past Discussions
2023, 2022, 2013, 3-25-2011, 3-8-2011, 2008, 2006 ~ HAL333 02:03, 14 December 2024 (UTC)
Discussion
- Support new image The current four images are low-quality, inconsistent, and unnecessarily clutter the infobox. More importantly, they fail to represent Parkinson's disease accurately, given its highly variable symptoms, which range from low blood pressure to cognitive decline. It's not even very clear what symptoms the current lead images are trying to illustrate, like the circled foot. These images violate Misplaced Pages:Manual of Style/Lead section as they are not genuinely representative. In contrast, a Lewy body—widely recognized as the hallmark biological feature of Parkinson's disease—provides a more accurate and universal depiction. Trying to accurately depict patients afflicted with a disease in the lead image is almost impossible and is not the standard on Misplaced Pages: see Cancer, Tuberculosis, Syphilis, or other neurodegenerative diseases like Huntington's disease, the FA Dementia with Lewy bodies, Multiple sclerosis, Alzheimer's disease, ALS, or Creutzfeldt–Jakob disease. ~ HAL333 02:03, 14 December 2024 (UTC)
- If anyone needs a direct comparison, these are the lead images on related articles:
- Multiple sclerosis
- Dementia with Lewy bodies
- Huntington's disease
- Multiple system atrophy
- Vascular dementia
- Leigh syndrome
- No (Summoned by bot) I don't find microscopic images of damaged tissue very informative to understanding the effect of a disease. The current image has been in the article for about one year, and this simpler image of the "Gowers' illustration" was in the article as early as 6-1-2019. In 2011, it was even a featured article with the "Gowers' illustration". Based on the discussions I included above, the Gowler's illustration seems historically significant--so I prefer seeing it included high up in the article as it is now. There seems to be a long-running consensus to keep an image such as the current one. About a year ago this image was floated and apparently rejected, which might be an acceptable alternative to the current one. --David Tornheim (talk) 04:28, 14 December 2024 (UTC)
- No. I don't think the proposed picture of a Lewy body helps the reader to understand anything at all about Parkinson's. --Alarics (talk) 11:21, 14 December 2024 (UTC)
- No: per above. --ZZ'S 16:05, 15 December 2024 (UTC)
- No. The proposed Lewy body image assumes the general user would understand or recognize the cellular effect, which is unlikely; see WP:WFTWA and WP:NOTTEXTBOOK #6,7. The disease symptoms image is a good choice for general users to visually grasp the article. Zefr (talk) 19:31, 15 December 2024 (UTC)
Prevention section
The subhead is misnamed - there is no 'prevention', only potential reduction of risk. All the sources used in this section are research-in-progress. The section should be retitled 'Research on risk reduction' and moved to below the 'Prognosis' section. Zefr (talk) 19:42, 15 December 2024 (UTC)
- The "Prevention" subsection has been around for quite some time, and is the standard on related articles like Alzheimer's disease, and is suggested per WP:MEDMOS. I think that this objection might be rooted in a misunderstanding of the meaning of "prevention" in a medical context. It quite literally means "potential reduction of risk" (per the NIH: "Prevention = In medicine, action taken to decrease the chance of getting a disease or condition"). Also, "Research on risk reduction" is a somewhat ungainly title, and don't essentially all of these subsections result from research? Should they all be titled "Research on X"? It seems redundant. ~ HAL333 21:26, 15 December 2024 (UTC)
- The word prevention may mislead general non-science users to conclude there are certain lifestyle practices for avoiding PD, WP:WFTWA. Moving this section into the 'Clinical research' topics seems the best place for it, but it should be significantly trimmed.
- The phrases "may have a protective effect", "hypothesized to be neuroprotective" or "proposed to be neuroprotective" are non-neutral (as they may not), are based on primary research, and are MOS:WEASEL. That is why I removed this. Zefr (talk) 22:26, 15 December 2024 (UTC)
- Yes, some of that material was cited to primary research papers and you rightly removed them. However, the only sources I've used in that subsection are secondary review articles. Also, the subsection immediately and explicitly states "no disease-modifying therapies exist that reverse or slow neurodegeneration" at the very beginning, so I don't think anyone is being misled.
- Regardless, although I see "Prevention" as a fine subtitle, do you think maybe retitling it as "Neuroprotection" or "Potential neuroprotection" would be a sufficient compromise? I also would not be opposed to splitting "Risk factors" from the "Causes" sections and then having a "Risk factors" section (as we used to) with "Positive risk factors" and "Negative risk factors" subtitles. ~ HAL333 22:57, 15 December 2024 (UTC)
- Better to use the positive and negative risk factors for subheads. Also, this source is not MEDLINE-indexed, so its content should be removed as unreliable. The Frontiers journals trigger a dubious source alert - would be good to find better reviews or remove them. Zefr (talk) 00:13, 16 December 2024 (UTC)
- Sounds good, I'll integrate the Prevention section and take a look at those sources tomorrow. Cheers, ~ HAL333 04:34, 16 December 2024 (UTC)
- There isn't really a concept of "positive risk factor" or "negative risk factor" so please don't create these as separate headers. You could talk about "protective risk factors" which is sometimes done. But probably best to just have a "risk factor" section. Smoking is a risk factor for lung cancer. Quit and it is protective. Start and it is the opposite. Same for most other risk factors - depends on whether the dose is increasing or decreasing. Jaredroach (talk) 05:14, 20 December 2024 (UTC)
- Frontiers review articles should be OK. See WP:MEDRS. But if there is a higher profile or more recent reference for the same thing, may be better to replace it. If it is an extreme or implausible claim, then be careful of any single source. Jaredroach (talk) 05:17, 20 December 2024 (UTC)
- Sounds good, I'll integrate the Prevention section and take a look at those sources tomorrow. Cheers, ~ HAL333 04:34, 16 December 2024 (UTC)
- Better to use the positive and negative risk factors for subheads. Also, this source is not MEDLINE-indexed, so its content should be removed as unreliable. The Frontiers journals trigger a dubious source alert - would be good to find better reviews or remove them. Zefr (talk) 00:13, 16 December 2024 (UTC)
- The concept of "prevention" includes interventions that are not 100% guaranteed to stop a disease. So a section on lifestyle interventions (such as exercise) that prevent (or stave off) PD is reasonable. All of medicine is in a process of continuous research, so it may not be necessary to overly emphasize that interventions (such as exercise) that are backed by a lot of research belong in a separate "researchy stuff" section. This article is in the scope of WP:MED, so it makes sense to follow WikiProject Medicine guidelines. I am not quite sure what a "non-science" user is, but if there is some writing that is hard to understand, we can work on making it more understandable, including links to epistemological concepts like risk factor (which needs some work) and causality. Jaredroach (talk) 05:26, 20 December 2024 (UTC)
Broken references
@HAL333 I've fixed a bunch of the shortened footnotes – you might like to double-check the edits in this combined diff, but there were a handful I couldn't work out (ref numbers are in this version of the article):
- #35 Weintraub & Mamikonyan 2019, p. 661 – I found this source but the page numbers don't match. Perhaps it's a typo for the paper cited in the previous reference?
- #42 Palma & Kaufmann 2020, pp. 1465–1466 – I corrected the other Palma & Kaufmann refs to 2018, but here the page numbers don't match
- #65 Tanner & Ostrem 2024 – no idea about this one
- #230 Corcoran, Muiño & Kluger 2021, p. 1 – ditto.
You might like to consider installing this script, which highlights problems with {{sfn}}s for you in lurid pink – I find it invaluable. Thanks for your work on the article, and thanks in advance for fixing the references above. Good luck at GAN! Best, Wham2001 (talk) 21:00, 24 December 2024 (UTC)
- Thanks, Wham2001! I'll start tackling these. ~ HAL333 20:49, 28 December 2024 (UTC)

- This is a huge topic so it may take me longer than usual to review, I'll fill out the table as I go and make comments below so it is easier for you to respond. At first glance, there is a few SFN errors that should be fixed. Additionally per WP:MEDDATE we should be using articles published within the last 5 years wherever possible. Because Parkinsons is such a hot topic I would imagine there is enough research to be able to do this. If you plan on taking this to FAC then I'd try to use the 5 year rule, but for the sake of GAN I try to stick to 10 years. Meaning every source published before 2015 (excluding NICE reviews, Cocheran reviews, and history section) should be replaced with more recent sources. IntentionallyDense 01:52, 26 December 2024 (UTC)
- I appreciate you tackling what will likely be a lengthy review. The ultimate goal is to bring this up to Featured status, so if you're more picky than is necessarily needed for the GAN process, that's quite fine for me. And I am perfectly happy if you take your time: I didn't expect this review to be initiated so quickly (I guess I've just been unlucky in the past) and I have an overseas mountaineering trip from December 31 through January 14. I'll try to make the occasional prose adjustment, but I'll only have my phone and an unreliable connection, so reference consultation will likely be limited. I'll be able to address all your comments within a few days of my return. ~ HAL333 00:10, 29 December 2024 (UTC)
- Sounds good. Knowing that you plan to take this to the FA level I'll leave some additional comments that will hopefully get you moving in the right direction. These will be completely optional but I will include them to hopefully give you a headstart. IntentionallyDense 04:02, 29 December 2024 (UTC)

6. Illustrated, if possible, by media such as images, video, or audio: | ||
6a. media are tagged with their copyright statuses, and valid non-free use rationales are provided for non-free content. | IntentionallyDense 02:24, 26 December 2024 (UTC) | |
6b. media are relevant to the topic, and have suitable captions. | Some minor issues are listed below. IntentionallyDense 02:24, 26 December 2024 (UTC)
Images are all captioned appropriately. IntentionallyDense 04:16, 29 December 2024 (UTC) | |
7. Overall assessment. | On hold until HAL333 can address the issues I have found thusfar. IntentionallyDense 21:14, 26 December 2024 (UTC) |
Images
- For the image under the motor section of symptoms "diminutive handwriting" isn't defined which is an issue cause the wikilink doesn't really help. A quick explanation would be nice. IntentionallyDense 02:24, 26 December 2024 (UTC)
- Is this just an WP:EASTEREGG issue? Let me know if my fix is sufficient. ~ HAL333 00:10, 29 December 2024 (UTC)
- Your fix looks good. IntentionallyDense 04:03, 29 December 2024 (UTC)

- Under the autonomic section, I don't feel like your image caption of Dysphagia—an autonomic failure—and subsequent complications like aspiration pneumonia (pictured) reduce quality of life. is super helpful here. Could it be changed to something along the lines of
Dysphagia can lead to aspiration pneumonia (pictured)
as the QOL isn't brought up elsewhere in this section so it feels out of place. IntentionallyDense 02:24, 26 December 2024 (UTC) - The caption under the two images in the causes section may read better as
The protein alpha-synuclein aggregates into Lewy bodies and neurites. Structural model of alpha-synuclein (left), photomicrograph of Lewy bodies (right).
to better explain the two images. IntentionallyDense 02:24, 26 December 2024 (UTC) - Under imaging the term "F-DOPA" is used but never explained. Is there a wikilink you could add or could you give a brief explanation on this? IntentionallyDense 02:24, 26 December 2024 (UTC)
- Under levodopa the acronym LCE is used. Could you spell this out in full? IntentionallyDense 02:24, 26 December 2024 (UTC)
- The wording of the caption under the tricycle is a little odd. Could you reword it? IntentionallyDense 02:24, 26 December 2024 (UTC)
- Under cell based therapies the caption says "one such iSPC differentiated" but I assume you mean iPSCs. IntentionallyDense 02:24, 26 December 2024 (UTC)
- All addressed. Let me know if any need further tweaking. ~ HAL333 00:16, 29 December 2024 (UTC)
- All looks good on the image part. Let me know once you get around to the citations and I'll continue my review after that. No preassure time wise as I suspect this will be a lengthy review. IntentionallyDense 04:17, 29 December 2024 (UTC)
- All addressed. Let me know if any need further tweaking. ~ HAL333 00:16, 29 December 2024 (UTC)
Sources
- You have quite a few borderline sources included here. I'll link all of the ones I found on a quick look. If you could replace as many of these as possible that would be great. IntentionallyDense 21:14, 26 December 2024 (UTC)
- Not all of these will need to be replaced. Try putting the issn into this website. For example, the journal "International journal of molecular sciences" (used in this pub) is indexed in a lot of databases while some of the other journals here aren't indexed in may databases.

Optional/nitpicks
- Since you plan to take this to the FA level I thought I'd leave some recommendations that I've gotten over at Misplaced Pages:Peer review/Neurocysticercosis/archive1. All of these are optional and will not effect the outcome of my decision here. IntentionallyDense 04:16, 29 December 2024 (UTC)
- There is some major overlinking with this article. I'll see what I can do myself but in general things only really need to be linked once. See MOS:LINKONCE. IntentionallyDense 04:16, 29 December 2024 (UTC)
- With the amount of technical terms (especially in the causes/pathophysiology section) there may be situations where it is appropriate to add a red link in. See Misplaced Pages:Red link. IntentionallyDense 04:16, 29 December 2024 (UTC)
- WP:MEDDATE will be taken much more seriously at the FA level. As will borderline sources. I suggest trying to replace as many of these as possible unless you are able to give a strong argument as to why they should be included over a newer article from a more reliable publisher. IntentionallyDense 04:16, 29 December 2024 (UTC)
- Scaling of images should be done with the |upright feature not by pixel size. See MOS:UPRIGHT. IntentionallyDense 04:16, 29 December 2024 (UTC)
- Alt text should be added to all images. See WP:MOSALT IntentionallyDense 04:16, 29 December 2024 (UTC)
- Sources should be ordered alphabetically. IntentionallyDense 04:16, 29 December 2024 (UTC)
- Anywhere where you can provide a page number you should. I see quite a bit of sfns without page numbers. IntentionallyDense 04:16, 29 December 2024 (UTC)
