Extreme morning chronotypes are often familial and not exceedingly rare: the estimated prevalence of advanced sleep phase familial advanced sleep phase and advanced sleep–wake phase disorder in a sleep clinic population

摘要

Report the first prevalence estimates of advanced sleep phase (ASP), familial advanced sleep phase (FASP), and advanced sleep–wake phase disorder (ASWPD). This can guide clinicians on the utility of screening for extreme chronotypes both for clinical decision-making and to flag prospective participants in the study of the genetics and biology of FASP.
