Summary Several epidemiologic studies carried out in Europe and North America show that sleep disorders may be considered as a common condition. Prevalence is higher in women and elder people. Around 10% to 19% of patients with insomnia remark its chronic condition. Sleep disorders in elderly patiens are associated with chronic afection, that is to say they are non lifetime dependent. Primary chronic insomnia is associated with emotional factors or stress, that might prevent sleep. Primary insomnia do neither depend on medical nor psychiatric condition. Secondary chronic insomnia may depend on an associated sleep disorder, psychiatric or medical condition, drugs and drugdependence. More frequent causes of insomnia are psychiatric disorders (anxiety, depression), neurologic disorders (Alzheimer disease, Parkinson disease, epilepsy, stroke, migraine), medical disorders (cardiovascular, respiratory, gastrointestinal, endocrine, rheumatic, neoplasic). Sleep disorders have also been described during pregnancy and menopause. Many medical drugs (metilxantine, antidepressive and antihypertensive agents, antiepileptic durgs, corticosteroids) and nicotine may sometimes produce severe insomnia.
