Definition of insomnia

Insomnia refers to the subjective perception of difficulty with sleep initiation, duration, consolidation, or quality that occurs despite adequate opportunity for sleep, and results in some form of daytime impairment.

An insomnia diagnosis requires associated daytime dysfunction in addition to appropriate insomnia symptomatology.
