Massive Cohort Study to Unravel Biological Roots of Chronic Excessive Sleepiness

Chronic hypersomnolence, or excessive daytime sleepiness, significantly impairs quality of life for millions, yet its underlying causes remain poorly understood. Conditions like narcolepsy, idiopathic hypersomnia, and sleep apnea often present with similar symptoms but have distinct pathophysiologies. There is a critical need for comprehensive, multi-modal datasets that integrate clinical, neurophysiological, and biological information to better classify these disorders and identify novel diagnostic and therapeutic targets.

This ongoing study is actively recruiting participants to build an unprecedented resource for sleep research. The primary 'finding' documented here is the successful establishment and ongoing expansion of a comprehensive cohort designed to integrate diverse data types. The study is on track to collect clinical, neurophysiological, and biological data from an estimated 5000 individuals, creating a robust platform for future investigations. This multi-faceted data collection will enable researchers to explore correlations between genetic predispositions, serum biomarkers, and the clinical presentation of various hypersomnolence disorders. > The establishment of this 5000-subject cohort, collecting genetic and serum samples alongside detailed clinical assessments, represents a foundational step towards understanding the complex etiology of chronic sleep disorders.
