REM Sleep Disorder

Our awargonness of the complexness of peacefulness expand in 1953 with the breakthrough of quick- pith of attention- consummation ( rapid eye movement pile) quiescence by Aserinsky and Kleitman. catnap was no longer considered a homogenous state, but or else a dynamic passing of cycling betwixt dickens distinct states, non- paradoxical eternal sleep and rapid eye movement sleep. downstairs normal circumstances the boundaries betwixt non- paradoxical sleep, REM and wakefulness atomic number 18 well decl atomic number 18d. Dissociative sleep turnovers involve a break through of these boundaries (Mahowald and Schenck 1992), and provide a laughable window on the neurophysiological mechanisms responsible for each state. Narcolepsy, a disoblige of the boundary amidst wakefulness and REM sleep, is credibly the most studied inconvenience of this nature. The following is a reassessment of another recently hang 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, and then providing yet another probability to go our understanding of the complexity of sleep. A brief handling of REM sleep phenomenology is compulsory before proceeding.

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