Finally in a review in 1995 Demirkiran and Jankovic stated the disease should be called paroxysmal kinesigenic dyskinesia instead, pointing out that the attacks could manifest as any form of dyskinesia, not just choreoathetosis. See also

Genetics probably contributes a very small amount to development of the disorder.One of the oldest explanations for somatization disorder advances the theory that it is a result of the bodys attempt to cope with emotional and psychological stress. The theory states that the body has a finite capacity to cope with psychological, emotional, and social distress, and that beyond a certain point symptoms are experienced as physical, principally affecting the digestive, nervous, and reproductive systems. There are many different feedback systems where the mind affects the body; for instance, headaches are known to be associated with psychological factors, and stress and the hormone cortisol are known to have a negative impact on immune functions. This might explain why somatization disorders are more likely in people with irritable bowel syndrome, and why patients with SSD are more likely to have a mood or anxiety disorder. There is also a much increased incidence of SSD in people with a history of physical, emotional or sexual abuse.Another hypothesis for the cause of somatization disorder is that people with the disorder have heightened sensitivity to internal physical sensations and pain. A biological sensitivity to somatic feelings could predispose a person to developing SSD. It is also possible that a persons body might develop increased sensitivity of nerves associated with pain and those responsible for pain perception, as a result of chronic exposure to stressors.Cognitive theories explain somatization disorder as arising from negative, distorted, and catastrophic thoughts and reinforcement of these cognitions.
