Alexithymia (pronounced: /ˌeɪlɛksəˈθaɪmiə/) from the Greek words λεξις and θυμος (literally "without words for emotions") is a term coined by Peter Sifneos in 1973 to describe people who appeared to have deficiencies in understanding, processing, or describing their emotions.

Classification

Alexithymia describes "people who have difficulties recognizing, processing, and regulating emotions". It is a personality trait that places individuals at risk for other medical and psychiatric disorders while reducing the likelihood that these individuals will respond to conventional treatments for the other conditions. Alexithymia is not classified as a mental disorder in the DSM IV. It is a personality trait that varies in severity from person to person. A person's alexithymia score can be measured with questionnaires such as the Toronto Alexithymia Scale (TAS-20), the Bermond-Vorst Alexithymia Questionnaire (BVAQ) or the Observer Alexithymia Scale (OAS).

In studies of the general population the degree of alexithymia was found to be influenced by age, but not by gender; the rates of alexithymia in healthy controls have been found at 8.3% (2 of 24 persons) 4.7% (2 of 43), 8.9% (16 of 179), and 7% (4 of 56). Thus, several studies have reported that the prevalence rate of alexithymia is less than 10% in healthy controls.

In another study, alexithymia was found to be approximately 13% of the population, with men (17%) almost twice as likely to be affected as women (10%). Specifically, men scored higher in difficulty describing feelings and for externally oriented thinking, but there was no gender difference whatsoever in difficulty in identifying feelings. The alexithymia construct is strongly inversely related to the concept of emotional intelligence . Other opinions differ and can show evidence that it may be state-dependent.

TypicalThose who have alexithymia report very logical and realistic dreams, such as going to the store or eating a meal.

According to Henry Krystal, individuals suffering from alexithymia think in an operative way and may appear to be superadjusted to reality. In psychotherapy, however, a cognitive disturbance becomes apparent as the patients tends to recount trivial, chronologically ordered actions, reactions, and events of daily life with monotonous detail.

A common misconception about alexithymia is that victims of this construct are totally unable to express emotions verbally and that they may even fail to acknowledge that they experience emotions. Even before coining the term, Sifneos (1967) noted patients often mentioned things like anxiety or depression. The distinguishing factor was their inability to elaborate beyond a few limited adjectives such as "happy" or "unhappy" when describing these feelings.

Relational issues

According to Vanheule, Desmet and Meganck (2006) alexithymia creates interpersonal problems because these individuals avoid emotionally close relationships, or that if they do form relationships with others they tend to position themselves as either dependent or impersonal, "such that the relationship remains superficial." Inadequate differentiation between self and other by alexithymic individuals has been observed by Blaustein & Tuber (1998).

In a study, a large group of alexithymic individuals completed the 64-item Inventory of Interpersonal problems (IIP-64 which screens for:

• (a) Domineering/Controlling, indicating difficulties relinquishing control over others;
• (b) Vindictive/Self-Centered behaviour, which describes problems of hostile dominance and the tendency to fight with others;
• (c) Cold/Distant behaviour, which refers to low degrees of affection for and connection with others;
• (d) Socially Inhibited, which assesses the tendency to feel anxious and avoidant in the presence of others;
• (e) Non-Assertiveness, which measures problems in taking initiative in relation to others and coping with social challenges;
• (f) Overly Accommodating, which indicates an excess of friendly submissiveness;
• (g) Self-Sacrificing, which indicates a tendency to affiliate excessively; and
• (h) Intrusive/Needy, which describes problems with friendly dominance.

The study found that alexithymic individuals "had significantly higher scores on all IIP-64 subscales than did the nonclinical sample."

Chaotic interpersonal relations have also been observed by Sifneos. Due to the inherent difficulties identifying and describing emotional states in self and others, alexithymia also negatively effects relationship satisfaction between couples.

In medical and psychiatric illness

Alexithymia frequently co-occurs with other disorders, with a representative prevalence of 85% in autistic spectrum disorders, 40% in posttraumatic stress disorder, 63% in anorexia nervosa and 56% in bulimia, 45% in major depressive disorder, 34% in panic disorder, and 50% in substance abusers.

Research indicates that alexithymia overlaps with Asperger syndrome. In a 2004 study, Uta Frith reports that not only does this overlap exist, but that at least half of the Asperger syndrome group obtained such extreme scores on the Toronto Alexithymia Scale (TAS-20) that "they would have been classified as severely impaired." Fitzgerald & Bellgrove pointed out that, "Like Alexithymia, Asperger’s syndrome is also characterised by core disturbances in speech and language and social relationships". Hill & Berthoz agreed with Fitzgerald & Bellgrove (2006) and in response stated that "there is some form of overlap between alexithymia and ASDs". They also pointed to studies that revealed impaired Theory of Mind skill in alexithymia, neuroanatomical evidence pointing to a shared aetiology and similar social skills deficits etc.

Alexithymia involves higher risk of developing certain personality disorders, and is correlated with particular illnesses, such as hypertension, inflammatory bowel disease, functional dyspepsia, sexual disorders, substance use disorders, and some anxiety disorders.

Etiology

It is unclear what causes alexithymia. Some neuropsychological studies indicate that alexithymia may be due to a disturbance to the right hemisphere of the brain, which is largely responsible for processing emotions. Other studies show evidence that there may be an interhemispheric transfer deficit among alexithymics; that is, the emotional information from the right hemisphere is not being properly transferred to the language regions in the left hemisphere, as can be caused by a decreased corpus callosum, often present in psychiatric patients who have suffered severe childhood abuse. In addition, another neuropsychological model suggests that alexithymia may be related to a dysfunction of the anterior cingulate cortex. These studies have some shortcomings, however, and the empirical evidence about the causes of alexithymia remain inconclusive.
