Abstract

A 15 year old boy presented with complaints of episodic hypersomnolence, sleeping for 16 to 18 hours a day which would happen for continuously 7 to 8 days, seven to eight times a year for the past 10 years. There was also history of voracious eating during such episodes. There was no history of trauma, seizure -like activity and no significant family history or psychosocial history. His blood sugar, growth hormone, prolactin levels were all normal. MRI brain with contrast done was also normal. Sixteen channel overnight polysomnography and Multiple Sleep Latency Test (MSLT) were done and found to be normal. Clinical features and significant negative tests led to a diagnosis of Kleine-Levin syndrome. He was started on Lithium and being monitored for reduction in frequency of symptoms.
