dcterms.abstract | Introduction Most adults with moderate to severe traumatic brain injury (TBI) report persistent sleep-wake disturbances. Whether these complaints are either associated with abnormal sleep-wake patterns or can be explained by TBI-related characteristics is unclear. The present study aimed at characterising the subjective and objective sleep-wake patterns in TBI adults by taking into consideration the influence of TBI severity, common comorbidities and psychoactive medication. Methods Overall, 34 adults with moderate-severe TBI (one to four years post-injury) were compared to 34 controls. Sleepiness, fatigue, sleep quality, mood, and pain were assessed with questionnaires. A seven day sleep diary and actigraphy was used to document sleep and wake patterns. Results Compared to controls, TBI participants reported more sleepiness and fatigue, as well as poorer sleep quality. On actigraphy, they had earlier bedtime and longer time spent in bed, but equivalent sleep efficiency during the nighttime episode compared to controls. TBI participants also took more naps and accumulated more time asleep over the 24 h period than controls. These group differences were accentuated when only TBI adults using psychoactive medication were included. More comorbidities, more severe injuries and longer hospital stay were positively correlated with fatigue, sleepiness and sleep duration. Conclusions Our results showed that despite complaints regarding sleep and diurnal functioning, TBI survivors have very marginal changes in their objective sleep-wake schedules. Prolonged time spent in bed may reflect an attempt to increase their sleep duration in response to fatigue and sleepiness. TBI adults who use psychoactive medication are those with more evident changes in their sleep-wake schedules. | fr |
