Organic Factors in Gilles de la Tourette's Syndrome

Abstract

Our hypothesis that patients with Gilles de la Tourette's syndrome have an impairment of the central nervous system is supported by analysis of data on 34 patients. Abnormalities were found in 76.7 per cent of patients on psychological testing, 50.0 per cent of electroencephalograms, 50 per cent of psychiatric, and 53.8 per cent of neurological examinations. The shortcomings of our data are discussed, especially the absence of an independently and blindly rated control group.
