The book presents a therapy concept for general practitioners, psychiatrists, neurologists, and psychotherapists involved in the care of patients with non-organic sleep disorders. A good network within the treatment system is necessary to intervene not only pharmacologically but also psychotherapeutically in the dynamics of a non-organic sleep disorder and to achieve a sustainable improvement in symptoms. Based on the guidelines of the S3 guideline for non-restorative sleep, the cognitive-behavioral therapy manual reflects the model of the dynamics of sleep disorders: With the help of 20 therapy modules featuring effective practical exercises, existing and researched techniques for alleviating non-organic sleep disorders can be integrated into the daily lives of patients and practitioners.
