Description of intervention(s) / exposure
This is an observational study of sleep in traumatic brain injury (TBI) in the inpatient rehabilitation setting. The study will seek to study sleep fragmentation and its recovery over time in TBI. The study will also examine the effect of sleep fragmentation and self-reported sleep quality on cognition, behaviour, mood, disability and life satisfaction.

Polysomonography (PSG) with electroencephalography (EEG) assessments with clinical assessments will be repeated fortnightly for up to 6 weeks following post-traumatic amnesia (PTA) resolution. If PSG with EEG is not feasible, an overnight pulse oximetry will be offered.

Statistical methods / analysis
Descriptive statistics and correlation between the pre-defined endpints using non-parametric analyses with p value for statistical significance at <0.05. Minimum important change (MIC) for sleep fragmentation is been defined as a 20% decrease from the baseline arousal index, and in executive functioning is defined as a 20% change in score for Executive domain, NUCOG.

Summary
Brief summary
The purpose of this study is to investigate the brain signalling in sleep after TBI. We want to know if sleep problems improve as time passes after the brain injury, and whether the recovery of sleep, sleep quality, and cognition are related. It is also possible that some patients after a severe TBI have breathing problems in sleep. It is possible that breathing problems in sleep could affect their recovery. The sleep study will include monitoring for breathing disorders during sleep.
