Each sleep cycle lasts about 90 to 110 minutes and includes stages that fall into two main phases: non-REM (or NREM) sleep and REM sleep. Non-REM sleep has three sub-stages: light sleep, deep ...
RBD is a sleep disorder characterized by the loss of normal skeletal muscle atonia during REM sleep and is associated with prominent motor activity and vivid dreaming. [6] [2] These dreams often involve screaming, shouting, laughing, crying, arm flailing, kicking, punching, choking, and jumping out of bed.
Rapid eye movement sleep behavior disorder (RBD), acting out violent or dramatic dreams while in REM sleep, sometimes injuring bed partner or self (REM sleep disorder or RSD). [88] Restless legs syndrome (RLS), an irresistible urge to move legs. Shift work sleep disorder (SWSD), a situational circadian rhythm sleep disorder.
Rapid eye movement sleep (REM sleep or REMS) is a unique phase of sleep in mammals (including humans) and birds, characterized by random rapid movement of the eyes, accompanied by low muscle tone throughout the body, and the propensity of the sleeper to dream vividly. The core body and brain temperatures increase during REM sleep and skin ...
REM sleep is decreased during the first half of the sleep period and stage 1 sleep is increased in the second half of the sleep period. [5] Most antidepressants, in particular selective serotonin re-uptake inhibitors (SSRIs), such as citalopram and paroxetine, are potent inhibitors of REM sleep and may also cause a REM rebound on discontinuation.
The REM Sleep Behavior Disorder Screening Questionnaire (RBDSQ) is a specific questionnaire for rapid eye movement behavior disorder (RBD) developed by Stiasny-Kolster and team, [1] to assess the most prominent clinical features of RBD. [2] It is a 10-item, patient self-rating instrument with short questions to be answered by either 'yes' or ...
Misalignments of the body's circadian pacemaker with the environment (e.g., jet lag, shift work, or other circadian rhythm sleep disorders) [7] Another underlying sleep disorder, such as narcolepsy, sleep apnea, [8] idiopathic hypersomnia, or restless legs syndrome; Disorders such as clinical depression or atypical depression [medical citation ...
Serotonin levels (in the form of 5-HT) have been shown to decrease during REM and NREM sleep, leading some researchers to believe that it is also involved in memory consolidation during sleep [citation needed]. Mice lacking the receptor gene for 5-HT engage in more REM sleep and perform better on spatial memory tasks. [48]
