[Gilles de la Tourette syndrome: a clinical study on 58 cases]

Abstract

Gilles de la Tourette's syndrome (GTS) is a neuropsychiatric disorder with a childhood onset and is characterized by motor and vocal tics. Fifty-eight patients with GTS were evaluated during a period of three years. Thirty-six patients were male and twenty two female, with an age range of 7 to 51 years (mean 20.33 years). The male to female ratio was 1.6:1. The age of onset ranged from 3 to 15 years (mean 7.81 years). Seventy nine percent of the patients presented motor tics as the initial symptom of the disease. In terms of complex tics, coprolalia was present in 27.6% of the patients; copropraxia in 20.1%; palilalia in 20.1%; ecolalia in 27.6%; and ecopraxia in 27,6%. Associated manifestations, such as attention deficit, hyperactivity disorder and obsessive-compulsive disorder were present in 25.8% and 39.6%, respectively. Sensory phenomena were present in 54.8% of the patients.
