Daytime sleepiness: more than just Obstructive Sleep Apnea (OSA).

Excessive Daytime Sleepiness (EDS) is a common condition with a significant impact on quality of life and general health. A mild form of sleepiness can be associated with reduced reactivity and modest distractibility symptoms, but more severe symptomatic forms are characterized by an overwhelming and uncontrollable need to sleep, causing sudden sleep attacks, amnesia and automatic behaviors. The prevalence in the general population is between 10 and 25%.

National validation and proposed revision of REM sleep behavior disorder screening questionnaire (RBDSQ).

We validated the Italian version of the rapid eye movement sleep behavior disorder (RBD) screening questionnaire (RBDSQ) and calculated its cut-off value for discriminating RBD group from other sleep disorders and healthy controls (HC). 380 patients with sleep disorders and 101 HC were enrolled. RBDSQ achieved an acceptable Cronbach's α value of 0.
