Awakenings
Awakenings deals with Parkinson's? I thought it was encephalitis. - Montréalais
The patients in Awakenings were suffering from post-encephalitic Parkinsonism. The encephalitis had occurred 50 years earlier and the infection was over. However it had left damage, causing their Parkinsonism. RTC 06:06 Nov 2, 2002 (UTC)
Amphetamines
I think it is more than worthwhile to mention amphetamines as a possible cause. (Minor comment reg. your last statement: the epidemic was in 1919-20 and the movie appears to play in the early fifties...which fits to the CV of Oliver Saks :-)
I'm sorry I edited the page. I was trying to prove to someone it doesn't actually edit it in real-time. Boy was I wrong. I did fix it though. Sorry again.
it's worth noting that ritalin is quite useful for the ADD like deficits in attention in PD.Bldavids 05:46, 10 January 2006 (UTC)
Ozzy?
Does Ozzy Ozbourne really have Parkinsons Disease? I know he has Parkinsonian symptoms, but I thought it was due to drug-induced damage to the dopaminergic system rather than actual PD. - Sayeth 22:24, Nov 18, 2004 (UTC
"Parkinson Disease" or "Parkinson's Disease"
The first name seems to be the more popular and proper one, being referenced more often in recent literature and on Google. taion 11:10, 23 Nov 2004 (UTC)
"inclinations towards Catholicism"
Is this a bogus edit?
- It's a jibe at John Paul II. JFW | T@lk 00:49, 18 August 2005 (UTC)
removed Katharine Hepburn
Katharine Hepburn did not have Parkinson's Disease. She had a condition called Essential tremor.
Micrographia
One of the symptoms mentioned is "micrographia (small handwriting)" — is this accurate? Is small handwriting symptomatic of disease? Either way, the link currently goes to an article about a popular science book, which I don't think was the author's intention. -- 213.122.16.164 20:04, 17 August 2005 (UTC)
- Well, micrographia alone is not particularly indicative of PD. In the context of other symptoms, though, it is an informative symptom. JFW | T@lk 00:48, 18 August 2005 (UTC)
The statement is accurate; it's a classic symptom. So, its presence is definitely informative but not diagnostic. sensitive but not specific. Bldavids 05:48, 10 January 2006 (UTC)
Exercise neuroprotective
I am dubious about the alleged "neuroprotective effect" of exercise. I'd like to see a reference please. --Dubbin 23:23, 23 September 2005 (UTC)
See: “Parkinson's Disease” an on-line summary @http://www.bcm.edu/neurol/jankovic/educ_pd.htm, by Joseph Jankovic, M.D., an internationally recognized expert on Parkinson disease, and the medical director of the Udall Parkinson Disease Research and Treatment Center in Houston (Note: “Udall Center” is a federal designation denoting excellence in PD treatment and research):
“Recent animal research has provided strong evidence that exercise can increase brain levels of neurotrophic factors, increase resistance to brain insult or injury, and improve learning and mental as well as motor performance.” There are a number of animal studies I could cite here, but Dr. Jankovic is a highly credible source and that quote saves me a lot of time.Bldavids 05:50, 10 January 2006 (UTC)
- Here's a good place to start: PMID 15214505. (Then click on "Related Articles" and you'll see many studies on the topic.) --Arcadian 18:08, 3 January 2006 (UTC)

Terminology depends on which side of the Atlantic you are on
Parkinson disease is used in American scientific literature. There has bee a move away from the apostrophe (e.g. Alzheimer disease vs. Alzheimer's disease). The British and the rest of the world use "Parkinson's disease" (preferred term).

neuropsychiatric aspects of parkinson's disease
Depression, anxiety, and executive dysfunction have been estimated to account for up to 70 percent of the disability associated with Parkinson disease. Dementia and psychosis may ultimately effect more than a third of all Parkinson patients. There is a movement among researchers and patients to weaken the emphasis on "movement disorder" and strengthen the emphasis on "neuropsychiatric disease".Bldavids 06:35, 16 January 2006 (UTC)
- If you have documentary support for this shift in paradigm it would make a very important point in the article. JFW | T@lk 12:17, 16 January 2006 (UTC)
symptoms that cross over the physical into the cognitive and affective
the lists as constituted are poor vehicles for certain symptom sets: for example, speech-language problems. 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 largely a function 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.
