Summary
Common and poorly recognized sleep movement disorders, including periodic limb movements and REM sleep behavior disorder, often present with sleep disturbance and daytime sleepiness. These conditions are diagnosable and treatable.
Area of Science:
- Neurology
- Sleep Medicine
Background:
- Movement disorders during sleep are frequently underdiagnosed.
- Common conditions include periodic limb movements of sleep and REM sleep behavior disorder.
Purpose of the Study:
- To review recently described, common, yet poorly recognized, sleep-related movement disorders.
- To highlight diagnostic and treatment approaches.
Main Methods:
- Comprehensive literature search utilizing databases up to July 1990.
- Included terms: sleep disorders, sleep myoclonus, nocturnal myoclonus, periodic movements in sleep, REM behavior disorder, and parasomnias.
- Manual searches of key journals and reference lists were also performed.
Main Results:
- Identified a spectrum of common and underrecognized movement disorders occurring during sleep.
- Symptoms often include disrupted sleep, excessive daytime somnolence, and abnormal nocturnal behaviors.
Conclusions:
- A distinct group of common, poorly recognized movement disorders during sleep exists.
- Patients typically present with sleep complaints and abnormal behaviors.
- These disorders are amenable to accurate diagnosis and effective management.
