Self-Reported Changes to Nighttime Sleep After Traumatic Brain Injury

Parcell DL, Ponsford JL, Rajaratnam SM, Redman JR. Self-reported changes to nighttime sleep after traumatic brain injury.ObjectivesTo explore subjective sleep reports from people in the chronic stages of traumatic brain injury (TBI) and to examine the extent and nature of sleep complaints in this population.DesignSurvey.SettingAll participants were community based at the time of data collection.ParticipantsSixty-three subjects with TBI consecutively recruited after discharge from rehabilitation and 63 age- and sex-matched controls from the general community.InterventionsNot applicable.Main Outcome MeasuresA 7-day self-reported sleep-wake diary assessing sleep and wake times, sleep onset latency, frequency, and duration of nocturnal awakenings and daytime naps; a general sleep questionnaire used to evaluate sleep changes and quality; and the Epworth Sleepiness Scale to measure daytime sleepiness.ResultsGroup-wise comparisons showed a significantly higher frequency of reported sleep changes after TBI (80%) relative to the control group (23%), supporting previous findings. The TBI group reported more nighttime awakenings and longer sleep onset latency; these changes were more frequently reported by participants with TBI with milder injuries. Increased levels of anxiety and depression were associated with increased reporting of sleep changes.ConclusionsThese findings confirm the experience of changes to sleep after TBI and may at least in part account for the reported increased daytime sleepiness in this population. Sleep disturbance should be addressed during rehabilitation. Treatments need to focus on correcting the underlying cause of the sleep problem and to address patients’ subjective experiences of their sleep, possibly through education and mood stabilization.
