Dyssomnias are a broad classification of sleeping disorders that make it difficult to get to sleep, or to remain sleeping.

Dyssomnias are primary disorders of initiating or maintaining sleep or of excessive sleepiness and are characterized by a disturbance in the amount, quality, or timing of sleep.

Patients may complain of difficulty getting to sleep or staying asleep, intermittent wakefulness during the night, early morning awakening, or combinations of any of these. Transient episodes are usually of little significance. Stress, caffeine, physical discomfort, daytime napping, and early bedtimes are common factors.

Major types of dyssomnias[edit]

There are over 30 recognized kinds of dyssomnias. Major groups of dyssomnias include:

Treatment[edit]

In general, there are two broad classes of treatment, and the two may be combined: psychological (cognitive-behavioral) and pharmacological. In situations of acute distress, such as a grief reaction, pharmacologic measures may be most appropriate. With primary insomnia, however, initial efforts should be psychologically based. Other specific treatments are appropriate for some of the disorders, such as ingestion of the hormone melatonin and bright light therapy for circadian rhythm disorders. Specialists in sleep medicine are trained to diagnose and treat these disorders.
