Abstract
Sleep paralysis is rare in the elderly but may occur particularly in families suffering from this phenomenon. In a minority of patients with disorders of arousal, the episodes persist until the age of 70. Zolpidem and other medications may induce sleepwalking and sleep eating-related syndrome. Most patients with idiopathic REM sleep behavior disorder (RBD) eventually develop Parkinson disease and dementia with Lewy bodies. Anti-IgLON5 disease includes abnormal behaviors in both nonrapid eye movement sleep and rapid eye movement sleep (REM) sleep. Restless legs syndrome prevalence increases with age until the sixth decade. A severe form of periodic limb movements in sleep may clinically mimic REM sleep behavior disorder (RBD).
