A 13-year-old boy presented with a 2 weeks history of tearfulness, childish behaviour, separation anxiety, hypersomnia, hyperphagia and sexual disinhibition following a brief episode of fever. He had been experiencing the episodes since he was seven. The episodes lasted from a few days to 3 weeks and would normally occur once in a year. Most of the time it started with fever and resolved spontaneously. In the past he described auditory hallucination but not this time. Examination revealed a slightly overweight adolescent male appearing appropriate to his age. During the session he was restless, sleepy and burst into tears frequently. He constantly asked his mother when he could go home to sleep. He was very childish and clung to his mother. He was given a trial of risperidone 1 mg to be taken once a day for 3 days. On follow-up he had completely recovered.
