Sleep Disorders, Circadian Rhythm
|
D020178 |

|
Sleep Disorders, Intrinsic
|
D020919 |
[Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)

Sleep Hygiene

Sleep Initiation and Maintenance Disorders
|
D007319 |
[Disorders characterized by impairment of the ability to initiate or maintain sleep. This may occur as a primary disorder or in association with another medical or psychiatric condition.
] |
|
Sleep Latency

Sleep Medicine Specialty

Sleep Paralysis
|
D020188 |
[A common condition characterized by transient partial or total paralysis of skeletal muscles and areflexia that occurs upon awakening from sleep or less often while falling asleep. Stimuli such as touch or sound may terminate the episode, which usually has a duration of seconds to minutes. This condition may occur in normal subjects or be associated with NARCOLEPSY; CATAPLEXY; and hypnagogic HALLUCINATIONS. The pathophysiology of this condition is closely related to the normal hypotonia that occur during REM sleep. (From Adv Neurol 1995;67:245-271)

Sleep Stages
|
D012894 |
[Periods of sleep manifested by changes in EEG activity and certain behavioral correlates; they formerly included Stage 1: sleep onset, drowsy sleep; Stage 2: light sleep; Stages 3 and 4: delta sleep, light sleep, deep sleep, telencephalic sleep. In 2007, sleep stages were redefined by The American Academy of Sleep Medicine (AASM) as: N1-N2 (sleep onset - light sleep), N3 (SLOW-WAVE SLEEP), and REM SLEEP.

Sleep Wake Disorders
|
D012893 |
[Conditions characterized by disturbances of usual sleep patterns or behaviors. SLEEP WAKE DISORDERS may be divided into three major categories: DYSSOMNIAS (i.e. disorders characterized by insomnia or hypersomnia), PARASOMNIAS (abnormal sleep behaviors), and SLEEP WAKE DISORDERS secondary to medical or psychiatric disorders. (From Thorpy, Sleep Disorders Medicine, 1994, p187)
, Abnormal sleep-wake schedule or pattern associated with the CIRCADIAN RHYTHM which affect the length, timing, and/or rigidity of the sleep-wake cycle relative to the day-night cycle.

|
Sleep, Slow-Wave
|
D000077310 |
[A stage of sleep characterized by synchronized wave activity as observed in the ELECTROENCEPHALOGRAM; the waves exhibit a frequency of 0.5 to 2 Hz, and a peak-to-peak amplitude greater than 75 microvolts.

|
Sleep-Wake Transition Disorders
|
D020922 |

Slipped Capital Femoral Epiphyses
|
D060048 |
[A developmental deformity in which the metaphysis of the FEMUR moves proximally and anteriorly away from FEMUR HEAD (epiphysis) at the upper GROWTH PLATE. It is most common in male adolescents and is associated with a greater risk of early OSTEOARTHRITIS of the hip.
