A Psychiatric Times report details the changes in sleep-wake disorders diagnoses in the DSM-5.
The DSM-5 Sleep-Wake Disorders Work Group worked closely with other nosology systems (eg, International Classification of Sleep Disorders, third edition [ICSD-3]) to incorporate changes in diagnoses. DSM-5 sleep-wake disorders are now more in sync with other medical disorders and sleep disorders classificatory systems. In DSM-5, the pathological and etiological factors associated with sleep-wake disorders are taken into consideration, as is the increase in awareness and knowledge gained from sleep studies. The aim is to increase uniformity and consistency among health care professionals when they are assessing and treating patients with various sleep disorders.
