Summary
Non-rapid eye movement (NREM) parasomnias require updated diagnostic criteria. Research suggests incorporating video-recordings and polysomnography markers for better diagnosis and classification of these sleep disorders.
Area of Science:
- Neurology
- Sleep Medicine
- Clinical Diagnostics
Background:
- Non-rapid eye movement (NREM) parasomnias are common, disabling sleep disorders.
- Current diagnostic criteria (ICSD-3-TR, 2023) lack updates since 2014.
- Existing criteria have inconsistencies and shortcomings impacting diagnosis.
Purpose of the Study:
- To review the diagnostic procedures for NREM parasomnias.
- To identify limitations in current diagnostic criteria.
- To propose revisions for more accurate classification.
Main Methods:
- Extensive literature review on NREM parasomnia diagnosis.
- Analysis of clinical and polysomnographic evidence.
- Evaluation of proposed diagnostic criteria revisions.
Main Results:
- Clinical criteria often serve as supportive, not mandatory, features.
- Infrared video-recording aids in characterizing home-based episodes.
- Specific polysomnographic markers for NREM parasomnias have been identified.
Conclusions:
- Current diagnostic criteria for NREM parasomnias need significant revision.
- Future classifications should integrate video-recording and polysomnography findings.
- Diagnostic specifiers are recommended for patient subgrouping in research and therapy.

01:07Narcolepsy
103
Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.

01:15REM Sleep Behavior Disorder
195
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.

Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).

01:18Nightmares and Night Terrors
93
Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.

The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...
