Sleep changes are frequently reported following traumatic brain injury (TBI) and have an impact on rehabilitation and quality of life following injury. Potential causes include injury to brain regions associated with sleep regulation, as well as secondary factors, including depression, anxiety, and pain. Understanding the nature and causes of sleep changes following TBI represents a vital step in developing effective treatments. Objective. The study aimed to investigate subjective sleep changes in a community-based sample of individuals with TBI in comparison with noninjured age- and sex-matched controls and to explore the impact of secondary factors (pain, anxiety, depression, employment) on these self-reported sleep changes.
