It involves abnormal behavior during the sleep phase with rapid eye movement (REM) sleep. The major feature of RBD is loss of muscle atonia (i.e., the loss of paralysis) during otherwise intact REM sleep (during which paralysis is not only normal but necessary). The loss of motor inhibition leads to sleep behaviors ranging from simple limb ...
The clinical practice of behavioral sleep medicine applies behavioral and psychological treatment strategies to sleep disorders. [3] [12] BSM specialists provide clinical services including assessment and treatment of sleep disorders and co-occurring psychological symptoms and disorders, often in conjunction with pharmacotherapy and medical devices that may be prescribed by medical professionals.
A person's chronotype is the propensity for the individual to sleep at a particular time during a 24-hour period. Eveningness (delayed sleep period; most active and alert in the evening) and morningness (advanced sleep period; most active and alert in the morning) are the two extremes with most individuals having some flexibility in the timing ...
Imagery rehearsal therapy (IRT) is a modified cognitive behavioral therapy technique used to treat recurring nightmares. This technique involves recalling the nightmare, writing it down, modifying parts of the dream to make it positive, and rehearsing the new dream to create a cognitive shift that counters the original dream.
One of the important questions in sleep research is clearly defining the sleep state. This problem arises because sleep was traditionally defined as a state of consciousness and not as a physiological state, [14] [15] thus there was no clear definition of what minimum set of events constitute sleep and distinguish it from other states of partial or no consciousness.
Previous studies in circadian biology have established that exposure to light during abnormal hours leads to sleep deprivation and disruption of the circadian system, which affect mood and cognitive functioning. While this indirect relationship had been corroborated, not much work had been done to examine whether there was a direct relationship ...
The response rate to sleep deprivation is generally agreed to be approximately 40-60%. A 2017 meta-analysis of 66 sleep studies with partial or total sleep deprivation in the treatment of depression found that the overall response rate (immediate relief of symptoms) to total sleep deprivation was 50.4% of individuals, and the response rate to partial sleep deprivation was 53.1% [3] In 2009, a ...
Actigraphy can assess sleep/wake patterns without confining one to the laboratory. The monitors are small, wrist-worn movement monitors that can record activity for up to several weeks. Sleep and wakefulness are determined by using an algorithm that analyzes the movement of the patient and the input of bed and wake times from a sleep diary.
