Insomnia is defined as difficulty in initiating, maintaining, duration, or quality of sleep. This results in an alteration of daytime functioning and quality of life. It is a common symptom that increases with age and is accompanied by significant morbidity. It is estimated that it affects between 6% and 48% of the general population

The most frequent insomnia is secondary to some organic or psychiatric disorder, or a modifiable external stimulus. In 30% of the cases, we speak of primary insomnia; in this case, the diagnosis is made by exclusion (insomnia without a triggering cause). The goal of treatment is to improve symptoms and quality of life. The treatment of choice sleep non-pharmacological measures. In cases where it is required, a hypnotic such as a benzodiazepine can be used at the lowest effective dose and for the shortest possible period.
