Cognitive-Behavioral and Pharmacological Treatments for Insomnia: A Combined Approach

Insomnia is the most prevalent sleep disorder (10-40%). It is defined as the subjective perception of difficulty with sleep initiation, duration, consolidation, or quality that occurs despite adequate opportunity for sleep and that results in some form of daytime impairment. Among the typical symptoms, there are fatigue, decreased mood or irritability, general malaise, and cognitive impairment. According to the International Classification of Sleep Disorders 3 rd  edition, ICSD-3, it has been defined as chronic (lasting more than three months) or short-term insomnia (less than three months). In clinical practice, the usual therapeutic approach is pharmacological (benzodiazepines, z drugs, slow wave sleep enhancers), even if the American Academy of Sleep Medicine (AASM), the American College of Physicians (ACP), and the European Sleep Research Society (ESRS) guidelines suggest that the first clinical choice should be non-pharmacological (cognitive behavioral therapy). A combined (non-pharmacological and pharmacological)approach could be considered in poor responders to manage drug dependence and to increase compliance to treatment and patients’ quality of life.
