• A 2-year-old boy of above-average intelligence experienced seizures, manifested by ticlike turning movements of the head, which were induced consistently by his own singing — not by listening to or imagining music. His seizures were also induced by his recitation and by his use of silly or witty language such as punning. The neurologic examination showed only a right-sided Babinski's sign. Seizure activity on an EEG was present in both temporocentral regions, especially on the right side, and was correlated with clinical attacks. A computed tomographic scan was normal. Phenobarbital therapy did not reduce seizure frequency.
