 Shri Rishi Psychiatry Clinic – Sleep-Wake Disorders Treatment


Sleep-wake disorders involve disruptions in sleep quality, timing, and the amount that results in daytime impairment and distress. They include the following disorders.

Insomnia Disorder:

Difficulty falling asleep or staying asleep is characteristic of insomnia disorder. Insomnia can be an independent condition, or it can be comorbid with another mental disorder, another sleep disorder, or another medical condition. It occurs more commonly in old age people and in highly anxious individuals with distorted normal sleep patterns.

Hypersomnolence Disorder:

Hypersomnolence disorder, also called hypersomnia, occurs when a person sleeps too much and feels excessively tired despite the normal or prolonged quantity of sleep.


Parasomnias are marked by unusual behavior, experiences, or physiological events during sleep. This category is divided into three subtypes:1) non-REM movement sleep arousal disorders, which involve incomplete awakening from sleep accompanied by either sleepwalking or sleep terror disorder; 2) nightmare disorder in which nightmares induce awakening repeatedly and cause distress and impairment; and 3) REM sleep behavior disorder, which is characterized by vocal or motor behavior during sleep.


Narcolepsy, as the name suggests, is a sudden attack of sleep while doing work in the daytime. It is marked by sleep attacks, usually with loss of muscle tone (cataplexy).

Breathing-Related Sleep Disorders:

There are three subtypes of breathing-related sleep disorders. The most common of the three is obstructive sleep apnea-hypopnea in which apneas (absence of airflow) and hypopneas (reduction in airflow) occur repeatedly during sleep, causing snoring and daytime sleepiness. Central sleep apnea is the presence of Cheyne-Stokes breathing in addition to apneas and hypopneas. Lastly, sleep-related hypoventilation causes elevated CO2 levels from decreased respiration.

Restless Legs Syndrome:

Restless legs syndrome is the compulsive movement of legs during sleep. It can be associated with anxiety, stress, habit or disorder proper.
