[Severe neuropsychic disturbances in a young adolescent treated with an endocrine therapy]

After a treatment based on the administration of gonadotropic drugs, aimed at reduced school difficulties and caracterial difficulties by a premature onset of puberty, a young male aged 13 1/2 presents: 1 degree somatic anomalies; 2 degrees increase of intellectual, affective and behavioral troubles; 3 degrees perturbations of EEG prophiles; 4 degrees organicity tests significantly disturbed. The interruption of treatment (4 years of observation) was followed by a progressive remission, however heterogenous, of all initial troubles. The observation underlines the dangers of utilising these treatments in a pre-puberty boy.
