Sleep is a complex neurological process essential for rest and energy restoration. The importance of sleep is highlighted by the fact that individuals typically spend about one-third of their lifetime asleep. Changes in the characteristics, amount, and regularity of sleep lead to sleep disturbances. Continuous and frequent disturbances during sleep can have detrimental effects on a person’s well-being. It is characterized into two main states based on behavior and physiology they are NREM sleep, which has four stages, and REM sleep, characterized by muscle atonia and desynchronized EEG. The circadian rhythm governing sleep-wake cycles is regulated by the master clock in the hypothalamus suprachiasmatic nuclei. Major sleep issues include Excessive daytime sleepiness, Insomnia, Abnormal sleep behaviors, and difficulty falling asleep at desired times. Key diagnostic tests for sleep disorders include overnight polysomnography and the multiple sleep latency test. In this article we will give information about its Epidemiology, etiology, Clinical presentation, types, diagnosis and their management of sleep disorders.
