JAMA patient page. Insomnia.

Insomnia is a sleep disorder that includes trouble falling asleep, staying asleep, or waking too early, resulting in daytime impairment. It is a common problem, usually occurring along with other diseases or emotional stress (comorbid insomnia). It can also exist without other medical or mental health causes (primary insomnia). Long-standing (chronic) insomnia can lead to daytime consequences such as fatigue or sleepiness, difficulty with thinking, and mood impairments, which can interfere with performance at school and work.
