Up to 35%-40% of all insomnia cases are associated with an underlying psychopathology, with affective and anxiety disorders being the commonest comorbid disorders (Ford & Kamerow, 1989 Breslau et al., 1996).

Idiopathic insomnia presents an insidious onset during childhood, unrelated to psychosocial stressors or medical disorders, and is very persistent throughout the adult life.

Paradoxical insomnia involves a genuine complaint of little or no sleep that is not corroborated by objective evidence of sleep disturbances.

Psychophysiological insomnia is the most classic form of insomnia and is the result from the repeated pairings of situational (bed/bedroom) and temporal (bedtime) stimuli, normally associated with sleep, with conditioned cognitive, emotional and/or physiologic arousal.

The International Classification of Sleep Disorders recognizes at least three different subtypes of primary insomnia: psychophysiological, paradoxical, and idiopathic insomnia (American Academy of Sleep Medicine, 2005 AASM).

Insomnia may be transient, episodic, or persistent over time (Morin & Espie, 2003). These complaints may involve problems with falling asleep initially at bedtime (initial insomnia), waking up in the middle of the night and having difficulty going back to sleep (middle insomnia), waking up too early in the morning with an inability to sleep until planned rise time (late insomnia), or a perception of non restorative sleep. Insomnia entails a spectrum of complaints reflecting dissatisfaction with the quality, duration, or continuity of sleep. Geneviève Belleville, Université du Québec à Montréal, Montréal, CANADA
