Abstract

Abstract: Introduction: Hypersomnolence is highly prevalent in the general population. However, we lack of information on how hypersomnolence evolves overtime. This study examines the prevalence, incidence and chronicity of DSM5 hypersomnolence in the US general population. Methods: The initial study was carried with 15, 929 individualsfrom 15 US States. The longitudinal study was carried on in eight of these states. A total of 12, 218 subjects were interviewed by phone during the first wave (W1) and 10, 930 at the second wave (W2) three years apart. The analyses were carried on the subjects who participated in both interviews (N=10, 930). Results: Hypersomnolence, occurring at least 3 days per week for at least 3 months despite a sleep duration of at least 7 hours, was observed in 15.6% (15.0%-16.2%) of the sample at W1. At W2, 22.1% (21.9%-23.4%) reported hypersomnolence. The incidence per year was 5.7%. Hypersomnolence was chronic in 36.7% of cases. Hypersomnolence accompanied with distress and/or impairment was less frequent with a prevalence to 2.6% (2.4%-2.8%) at W1 and 2.1% (1.8%-2.4%) at W2 but chronicity was lower (14.5%). This suggests that while hypersomnolence may still be present, its consequences on daytime functioning decreased over time. Conclusion: Hypersomnolence is an important problem in the U.S. population and often chronic. It has to be taken seriously and requires attention from public health authorities, scientists and clinicians. Support (If Any): NIH and John-Arrillaga Foundation
