Sleep disorders types
How are sleep disorders classified?
- 1. Insomnia—includes chronic insomnia, short-term insomnia, and other insomnia disorders
- 2. Sleep-related breathing disorders—include obstructive sleep apneas, central sleep apnea syndromes, and sleep-related hypoventilation/hypoxemic syndromes
- 3. Central disorders of hypersomnolence—excessive daytime sleepiness not due to a circadian rhythm sleep disorder, sleep-related breathing disorder, or other cause of disturbed nocturnal sleep
- 4. Circadian rhythm sleep–wake disorders—characterized by a persistent or recurrent pattern of sleep disturbance due to alterations of the circadian timing system or a misalignment between the timing of the individual’s endogenous circadian rhythm of sleep propensity and exogenous factors that affect the duration or timing of sleep
- 5. Parasomnias—include confusional arousals, sleepwalking, sleep terrors, REM sleep behavior disorder, nightmares, sleep enuresis, and sleep talking
- 6. Sleep related movement disorders—include restless legs syndrome, periodic limb movement disorder, sleep-related leg cramps, sleep-related bruxism (teeth grinding), and rhythmic movement disorder
