Gonadotropin-releasing hormone agonist against severe aggression in autism.

Aggression in patients with autism spectrum disorder (ASD) presents an important therapeutic challenge. Conventional treatment appears to be inadequate in a number of cases. The occurrence of severe aggressive symptoms since the inception of adolescence in a male patient with ASD suggested a hormonal influence by androgens. Conventional treatment with antipsychotic and antiepileptic drugs and benzodiazepines was ineffective. A subcutaneous long-acting gonadotropin-releasing hormone agonist (GnRH agonist) injection was given on a monthly basis resulting in a substantial improvement in his aggressive behaviour and renewed socialisation. 2016 BMJ Publishing Group Ltd.
