Sleep recordings show disrupted and less consistent sleep after traumatic brain injury
Compared with controls, patients with traumatic brain injury took longer to fall asleep and had more disrupted sleep. The abstract does not report how large these differences were.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Patients with traumatic brain injury showed longer delays before falling asleep, more waking after sleep began, and poorer sleep efficiency than controls. Their sleep also varied more from night to night. These findings describe differences in recorded sleep patterns; they do not establish that the injury caused every difference or identify an effective treatment.
The abstract provides no numerical estimates of the sleep differences and does not describe injury severity, participant ages or control characteristics. Their practical size and relevance to particular patients therefore remain unclear.
Several aspects of sleep differed
The review used actigraphy, an objective method for recording sleep-wake patterns. Sleep efficiency describes how much of the sleep period is spent asleep. Patients showed poorer efficiency alongside more waking and a longer wait for sleep.
Consistency was also an outcome
Patients had greater night-to-night variation in total sleep time and waking after sleep began. This concerns consistency across nights. The abstract does not report a clear result for average total sleep duration, so that outcome remains unspecified here.
