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 ...
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.
The cyclic alternating pattern (abbreviated CAP) is a pattern of two long-lasting alternate electroencephalogram (EEG) patterns that occur in sleep. [1] It is a pattern of spontaneous cortical activity [ 2 ] which is ongoing and occurs in the absence of sensory stimulation .
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.
Cognitive-behavioral therapy is most closely allied with the scientist–practitioner model in which clinical practice and research are informed by a scientific perspective, clear operationalization of the problem, and an emphasis on measurement, including measuring changes in cognition and behavior and the attainment of goals.
Other efforts that may be tried include sleep hygiene, cognitive behavioral therapy, and antidepressants. [1] Between 8% and 50% of people experience sleep paralysis at some point during their lives. [2] [4] About 5% of people have regular episodes. Males and females are affected equally. [2] Sleep paralysis has been described throughout history.
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.
EMG (electromyography) is a crucial method to distinguish between sleep phases: for example, a decrease of muscle tone is in general a characteristic of the transition from wake to sleep, [5] [6] and during REM sleep, there is a state of muscle atonia (paralysis), resulting in an absence of signals in the EMG.
