Insomnia is a common treatable disorder of insufficient or poor-quality
sleep, with adverse daytime consequences.1 Insomnia
presents as trouble falling asleep (long-sleep latency), trouble staying asleep
(excessive or prolonged awakenings), or feeling nonrestored from sleep. Insomnia
can be a primary disorder emerging in childhood or later, a conditioned (psychophysiological)
disorder, or comorbid with a psychiatric, medical, or other sleep disorder.1 Insomnia can be transient (related to stress, illness,
travel) or chronic (occurring nightly for >6 months). Persistent untreated
insomnia is a strong risk factor for major depression.2 Insomnia
must be distinguished from sleep-state misperception and short sleep states
