Characterization of the Sleep-Wake Cycle in Traumatic Brain Injury Patients with a Disorder of Consciousness

Characterization of the Sleep-Wake Cycle in Traumatic Brain Injury Patients with a Disorder of Consciousness

Each year in France, 160,000 peoples suffer from a mild or severe traumatic brain injury (TBI). Sleep plays a crucial role in the process of brain plasticity, which is essential for neurological and cognitive recovery. However, the sleep-wake cycle is rarely, if ever, evaluated in patients with TBI and consciousness disorders within Post-Resuscitation Rehabilitation Units (SRPR). Caregivers develop, on a daily basis, an intuitive understanding of the patient's overall condition. This expertise deserves to be validated using objective sleep assessment tools (actigraphy). If proven accurate, it could lead to the implementation of a sleep-wake cycle evaluation protocol within SRPRs.
