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.
[1] [35] The variant sleep-related eating disorders is chronic, without remission, but treatable. [35] REM sleep behavior disorder (RBD) can mostly be handled well with the use of melatonin or clonazepam. [25] [35] However, there is high comorbidity with neurodegenerative disorders, that is in up to 93% of cases. [35]
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.
Experts explain what parasomnias are and treatment options.
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 ...
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.

Animal studies have partly validated these claims. For instance, one study conducted with rats showed that REM sleep deprivation after learning a new task disrupted their ability to perform the task again later. This was especially true if the task was complex (i.e., involved using unusual information or developing novel adaptive behaviours). [38]
Night terror, also called sleep terror, is a sleep disorder causing feelings of panic or dread and typically occurring during the first hours of stage 3–4 non-rapid eye movement (NREM) sleep [1] and lasting for 1 to 10 minutes. [2]
