Abstract:
The prevalence of fatigue among individuals with traumatic brain injury living in the community is estimated to range between 50% and 80%. The need to clarify the contributing factors to fatigue is driven by the availability of different treatments. This longitudinal study will examine the dynamic nature of fatigue experienced by individuals with TBI in the first two years post-injury and will document whether the nature of fatigue changes within that time frame. It will assess whether factors such as concurrent medications, sleep findings, affective symptomatology, activity patterns and limitations, substance use, and neuroendocrine profiles may contribute to the changes in fatigue dimensions within the first two years post-TBI.
