Sleep disorders in traumatic brain injury

Background Sleep disorders play a significant role in the care of those with Traumatic Brain Injury (TBI). Objective To provide a literature review on the interaction of sleep and circadian processes on those with TBI. Methods A literature review was conducted on PubMed using the following key words and their combination: "Sleep Apnea", "Traumatic Brain Injury", "Circadian", "Parasomnia", "Insomnia", "Hypersomnia", "Narcolepsy", and "Restless Legs". We review the spectrum of traumatic brain injury associated sleep disorders and discuss clinical approaches to diagnosis and treatment. Results Disordered sleep and wakefulness after TBI is common. Sleep disruption contributes to morbidity, such as the development of neurocognitive and neurobehavioral deficits, and prolongs the recovery phase after injury. Early recognition and correction of these problems may limit the secondary effects of traumatic brain injury and improve neuro recovery/patient outcomes. Conclusions A more focused approach to sleep health is appropriate when caring for those with TBI.
