The Psychomotor Vigilance Task (PVT) is a reliable and objective tool for measuring sleep inertia in patients with idiopathic hypersomnia (IH) and other sleep disorders.
Why this matters
Sleep inertia (difficulty waking up and “getting going” after sleep or naps) is a frequent symptom of IH, which can significantly impair a person’s quality of life.
Research of sleep inertia has mainly included healthy subjects and studies in patients with hypersomnolence conditions are lacking.
This is the first study investigating sleep inertia after nocturnal awakening in IH using the PVT tool, which has never been tested in IH.
