Abstract

"We report two patients with frequent isolated sleep paralysis (SP). They have neither cataplexy nor daytime sleepi-ness, and there was no HLA DR2 or DQ1 association. We elicited one episode of sleep paralysis from a patient by a sleep interruption schedule. The polysomnographic recording during SP showed abundant alpha rhythm with persistent atonia, which indicate a concurrence of REM-atonia and wakefulness. The frequency of SP was markedly reduced by a use of clomipramine Key Words : Isolated sleep paralysis, REM sleep, Polysomnography"
