title: Relationship of age to neuropsychological deficit in Tourette's syndrome.
abstract: A previous study suggested that neuropsychological deficit in patients with Gilles de la Tourette's syndrome (TS) may increase with age. This question was studied by examining the relationship between age and neuropsychological deficit in 21 TS patients. It was found that increased age was related to greater neuropsychological deficit on a pattern of measures consistent with previous reports. The use of age corrected t-scores ruled out the general relationship of age with test performance as an explanation of these results. In addition, when the subjects were grouped on the basis of age, older patients were significantly worse than younger patients on several measures.
