AbstractSleep disorders are common in the general adult population and are associated with adverse effects such as motor vehicle collisions, decreased quality of life, and increased mortality. Patients with sleep disorders can be categorized into three groups: people with problems falling asleep, people with behavior and movement disturbances during sleep, and people with excessive daytime sleepiness. Insomnia, the most common sleep disorder, is defined by difficulty initiating sleep, maintaining sleep, or both, resulting in daytime consequences. Insomnia is diagnosed by history and is treated with cognitive behavior therapy, with or without medications. Rapid eye movement sleep behavior disorder is characterized by increased muscle tone during rapid eye movement sleep, resulting in patients acting out their dreams with potentially harmful effects. Rapid eye movement sleep behavior disorder is diagnosed by polysomnography and treated with melatonin or clonazepam. Restless legs syndrome is defined by an urge to move the legs that worsens when at rest. Restless legs syndrome is treated with gabapentin or dopamine agonists, depending on the severity. Narcolepsy is characterized by excessive daytime sleepiness, cataplexy, sleep paralysis, and sleep hallucinations. Diagnosis is suggested by the history and can be confirmed with polysomnography and a multiple sleep latency test the following day. Narcolepsy is treated with behavior modifications and medications such as stimulants, selective serotonin reuptake inhibitors, sodium oxybate, and pitolisant. Obstructive sleep apnea may be diagnosed in patients with excessive snoring and witnessed apneas and can be diagnosed using overnight polysomnography. Treatment consists of positive airway pressure therapy while sleeping in conjunction with weight loss.
