Some tics are intentional movements made in an attempt to diminish uncomfortable sensations. These sensations, sometimes termed sensory tics, are focal and usually arise in the part of the body involved in the subsequent motor act. We report a patient whose sensations associated with tics were felt in other people and in objects. The discomfort associated with his out-of-body sensations was temporarily relieved by touching or scratching the object involved. The definition of premonitory sensations should be expanded to include extracorporeal sensations, and a history of external sensations should be sought in patients with Tourette's syndrome. Theories on the generation of tics must incorporate an explanation for extracorporeal sensations.

D005879	Tourette Syndrome	A neuropsychological disorder related to alterations in DOPAMINE metabolism and neurotransmission involving frontal-subcortical neuronal circuits. Both multiple motor and one or more vocal tics need to be present with TICS occurring many times a day, nearly daily, over a period of more than one year. The onset is before age 18 and the disturbance is not due to direct physiological effects of a substance or another medical condition. The disturbance causes marked distress or significant impairment in social, occupational, or other important areas of functioning.

D013981	Tic Disorders	Disorders characterized by recurrent TICS that may interfere with speech and other activities. Tics are sudden, rapid, nonrhythmic, stereotyped motor movements or vocalizations which may be exacerbated by stress and are generally attenuated during absorbing activities. Tic disorders are distinguished from conditions which feature other types of abnormal movements that may accompany another another condition.
