REM Sleep Disorder

Our awargonness of the complexity of peacefulness grow in 1953 with the breakthrough of speedy- midway of attention- motion ( rapid eye movement relaxation) relief by Aserinsky and Kleitman. balance was no longer considered a homogenous state, but kind of a dynamic cut through of cycling betwixt deuce distinct states, non- rapid eye movement rest period and rapid eye movement sleep. to a lower place normal circumstances the boundaries among non-rapid eye movement, REM and wakefulness ar well decl ared. Dissociative sleep turnovers involve a disperse of these boundaries (Mahowald and Schenck 1992), and provide a singular window on the neurophysiological mechanisms responsible for each state. Narcolepsy, a perturbation of the boundary amidst wakefulness and REM sleep, is credibly the most studied ail of this nature. The following is a reexamine of another recently order forth REM sleep boundary disorder called REM sleep behavior disorder (RBD). RBD is characterized by the acting-out of violent dreams during REM sleep, often with injurious consequences (Schenck et al. 1986, 1987). As with narcolepsy, RBD involves a dissociation of REM sleep phenomena and their underlying mechanisms, hence providing yet another hazard to go our understanding of the complexity of sleep. A brief news of REM sleep phenomenology is infallible before proceeding.

REM sleep is characterized by specific phenomena that disunite it from non-REM sleep and wakefulness (Siegel 1994). These phenomena are grouped according to whether their happening is tonic (occurring throughout REM) or phasic (occurring intermittently during REM). Tonic phenomena include, low-tension desynchronized electroencephalogram (EEG), hippocampal theta rhythm, electromyographic (EMG) atonia, olfactory myeline activity, steep arousal threshold, reverend brain temperature, poikilothermia, and penile tumescence. Phasic phenomena include, rapid eye movements, ponto-geniculo-occipital spikes, somatic muscle-limb twitches, bosom ear activity, tongue movements, and division in autonomic stop of cardiac and respiratory functions.
