Sleep structure and awakening threshold in delayed sleep-wake phase disorder patients compared to healthy sleepers

Difficult early morning awakening is a primary symptom of delayed sleep-wake phase disorder (DSWPD), however, it remains poorly investigated. Our main objective was to quantify the awakening threshold in DSWPD-patients and healthy controls and investigate a possible relationship with sleep stage. A secondary objective was to compare habitual sleep measured by polysomnography and actigraphy between patients and controls.
