Sleep onset insomnia is the inability to fall asleep naturally. Sleep maintenance insomnia is the inability to stay asleep or to resume sleep after waking in the middle of the sleep cycle. A person may experience both sleep onset insomnia and sleep maintenance insomnia, which leads to both insufficient and poor sleep. Insomnia can be categorized further as acute or chronic. Acute insomnia is self-limiting, meaning it runs its course in a few weeks or months and ends without being treated.
Chronic insomnia lasts longer than three months and often needs to be treated.
Incidence The prevalence of insomnia is unknown. Since insomnia is frequently a symptom of illness, severe stress, trauma, and so on, its incidence varies with regard to age, sex, and severity of the predisposing condition.
