Abstract: Gilles de la Tourette''s syndrome (GTS) consists of multiple motor tics and one or more phonic tics. Psychopathology occurs in approximately 90% of GTS patients, with attention-deficit/hyperactivity disorder (ADHD) and obsessive–compulsive disorder (OCD) being common. Depression is common, with a lifetime risk of 10% and a prevalence of between 1.8% and 8.9%. Depression and depressive symptoms are found to occur in 13% and 76% of GTS patients attending specialist clinics, respectively. In controlled studies embracing over 700 GTS patients, the patients were significantly more depressed than controls in all but one instance. In community and epidemiological studies, depression in GTS individuals was evident in two of five investigations. Clinical correlates of depression in people with GTS appear to be: tic severity and duration, the presence of echophenomena and coprophenomena, premonitory sensations, sleep disturbances, obsessive–compulsive behaviors/OCD, self-injurious behaviors, aggression, conduct disorder (CD) in childhood, and, possibly, ADHD. Depression in people with GTS has been shown to result in a lower quality of life, potentially leading to hospitalization and suicide. The etiology of depression appears to be multifactorial. Bipolar affective disorder (BAD) and GTS may be related in some individuals. However, it is noted that sample sizes in most of these studies were small, and it is unclear at the present time as to why BAD may be overrepresented among GTS patients. [Copyright &y& Elsevier]


Robertson, M. M., Eapen, V., & van de Wetering, B. M. (1995). Suicide in Gilles de la Tourette's syndrome: Report of two cases. Journal of Clinical Psychiatry, 56(8), Retrieved from EBSCOhost.

Presents 2 cases illustrating the relationship between Gilles de la Tourette's syndrome (TS), suicide, depression, and obsessive-compulsive and self injurious behaviors. A 33-yr-old man and a 27-yr-old woman with TS presented with motor and vocal tics, obsessive-compulsiveness, and self-injurious behavior. Histories of both Ss revealed the presence of multiple stresses, including social stigma, restrictions on autonomy, illness or treatment disrupted normal functioning, limited opportunities for social activities, and burdened families. Despite therapy, both patients committed suicide. It is suggested that TS is a spectrum disorder, with comorbid depression, obsessive-compulsive disorder, attention-deficit disorder, and self injurious behavior. Regular monitoring of mental state, and thorough evaluation of psychosocial and adaptational difficulties coupled with prompt and appropriate intervention in TS cases is essential.

I have TS and understand after 40 years of it why a person with TS would want to kill themselves. Is there no end to this agony.
