Boundary-Dependent Sleep-Wake Dysregulation in Idiopathic Hypersomnia. [PDF]
Ann Clin Transl NeurolABSTRACT Objective Idiopathic hypersomnia (IH) presents with excessive daytime sleepiness (EDS) despite apparently preserved nocturnal sleep, challenging traditional models of hypersomnolence based on sleep loss or fragmentation. We aimed to test the hypothesis that EDS in IH reflects excessive stabilization of the sleep state, consistent with ...
