Abstract:
Kleine-Levin syndrome (KLS) is characterized by recurring episodes of hypersomnia, megaphagia, and abnormal behavior. We report two cases of KLS. Two boys, aged 18 (case 1) and 17 (case 2), had recurrent episodes of hyper-somnolence with compulsive eating or drinking and hypersexuality for several years. HLA-DR typing was HLA-DR3 and 13 in case 1 and HLA-DR4 and 10 in case 2. Case 1 showed hypersomnia with early onset of REM sleep on MSLT and frequent frontal intermittent rhythmic delta activity on EEG. Both cases showed no abnormalities on brain MRI. HLA-DR typing facilitates differentiation between KLS and narcolepsy by the absence of HLA-DR2.
