Childhood obsessive-compulsive disorder and cingulate epilepsy

There are no reports of an association between obsessive-compulsive disorder and cingulate epilepsy in childhood. We report the behavioral, cognitive, and EEG findings in a young girl with medically resistant seizures and severe obsessive-compulsive symptomatology. Her scalp EEG and neuropsychological test scores suggested right frontal lobe dysfunction. The intractability of her seizures and progressive intellectual and psychosocial deterioration prompted evaluation for excisional surgery. Intracranial EEG recording demonstrated a focal seizure origin in the right anterior cingulate gyrus. Cingulotomy resulted in freedom from seizures and significant improvement in her obsessive-compulsive symptoms.
