title: Gelastic seizures, precocious puberty, and hypothalamic hamartoma.
abstract: The concurrence of gelastic (laughing) seizures and precocious puberty has been reported in 18 patients, including 2 described here. At least 10 patients had hypothalamic hamartomas. Improvements in cerebral imaging permit noninvasive diagnosis. Surgical intervention in seven of these patients was of little diagnostic or therapeutic benefit.
