ICSD Revised Classification of Adult Insomnia
Primary Insomnia
- Idiopathic insomnia: Insomnia arising in infancy or childhood with a persistent, unremitting course
- Psychophysiologic insomnia: Insomnia due to a maladaptive conditioned response in which the patient learns to associate the bed environment with heightened arousal rather than sleep; onset often associated with an event causing acute insomnia, with the sleep disturbance persisting despite resolution of the precipitating factor
- Paradoxical insomnia (sleep-state misperception): Insomnia characterized by a marked mismatch between the patient’s description of sleep duration and objective polysomnographic findings
