Sleepiness and Fatigue in Circadian Rhythm Sleep Disorders  (2023)
Abstract Header
This article describes how sleepiness and fatigue are expressed among patients with circadian rhythm sleep disorders (CRSD). Although sleepiness and fatigue are common complaints among those with CRSDs, the pattern of expression of these symptoms vary by condition and by the methods used to assess sleepiness and fatigue. This article reviews the methods used to assess sleepiness and fatigue and describes how these symptoms are expressed in each CRSD.
