Nocturnal Myoclonus Syndrome (C0751774)

Definition (MSHCZE) Periodické pohyby končetinami ve spánku – porucha, při níž vznikají rytmické stereotypní pohyby obv. dolních končetin s častým probouzením a sníženou kvalitou spánku, druh dyssomnie. K tomuto stavu predisponuje řada celkových onemocnění (parkinsonismus, uremie, diabetes aj.), existuje vztah k syndromu neklidných nohou. Benigní hypnagogické záškuby jsou jednorázové, jen vzácně se opakující záškuby. Angl. periodic limb movements in sleep - PLMS. (cit. Velký lékařský slovník online, 2013 )
Definition (MSH) Excessive periodic leg movements during sleep that cause micro-arousals and interfere with the maintenance of sleep. This condition induces a state of relative sleep deprivation which manifests as excessive daytime hypersomnolence. The movements are characterized by repetitive contractions of the tibialis anterior muscle, extension of the toe, and intermittent flexion of the hip, knee and ankle. (Adams et al., Principles of Neurology, 6th ed, p387)
