title: [Precocious puberty and laugh attacks].
abstract: A 7 year old girl presented with precocious puberty and ictal laughter. Brief, repetitive, stereotyped attacks of laughter were the first manifestation of the epileptic syndrome. Stages of puberty were noted as B III-IV and PH II according to Tanner. X-rays showed a bone age of 11 years and the weight increased from the 50th beyond 97th percentile. Plasma concentrations of LH, FSH, testosterone and Ostradiol were elevated. The CT scan was normal and a magnetic resonance imaging showed an hypothalamic hamartoma. The control of the seizures control and social adjustment were poor. MR scanning 3 years later showed no change in the size of the lesion.
