Estimating burden of disease among blind individuals with non 24 hour sleep wake disorder

Introduction: Non 24 Hour Sleep Wake Disorder (N24HSWD) is a circadian rhythm disorder with a significant impact on social and occupational functioning. We utilized longitudinal sleep diary data in order to quantify the burden of disease in blind patients with N24HSWD. Daytime sleep episodes interfere with school work and social activities and therefore Daytime Sleep Free Days (DSFD) can act as a surrogate of healthy days for patients with N24HSWD.
