摘要：Kleine-Levin syndrome (KLS) is an uncommon syndrome characterized by recurrent episodes of hypersomnia, behavioural and/or cognitive disturbances, abnormal eating and hypersexual behaviour. The diagnosis is clinical and requires a high index of suspicion and exclusion of other neurological conditions and sleep disorders. We report a case of 15-year-old male who had recurrent episodes of hypersomnia with hyperphagia, hypersexuality, disinhibition and cognitive dysfunction. His brain CT scan shows Mega cistern magna and EEG during the episode shows sharp and spike wave in both frontal and temporal lobes with secondary generalization. The patient became symptom-free after receiving Na Valporate.
