Insomnia, Fatigue, and Sleepiness in the First 2 Years After Traumatic Brain Injury

Abstract

Although PTBIF and insomnia are closely related and both associated with poorer quality of life, they are affected independently by a variety of factors, especially psychopathology and sleep quality. A majority of individuals with PTBIF do not have insomnia; and PTBIF appears to be related to disability severity and daytime sleepiness, where insomnia is not. Demographic and injury variables are not strong predictors of insomnia or PTBIF.
