Electroencephalographic (EEG) abnormalities in a series of 45 patients with Tourette's syndrome were related to clinical and historical factors in this study. Twenty-one of the 45 tracings (47%) exhibited abnormalities; the most common abnormalities noted included sharp waves and slowing. A posterior focus of abnormal activity was noted in 16 cases. Subjects with an earlier age of onset were significantly more likely to have abnormal EEGs. © 1984, The American Academy of Child Psychiatry. All rights reserved.
