Modafinil for the Treatment of Fatigue and Excessive Daytime Sleepiness in Individuals With Traumatic Brain Injury

Background: An estimated 5.3 million Americans are living with a TBI-related disability today. These persons may face many issues, however, two chronic problems seem common to a strikingly large number of those who survive TBI: fatigue and EDS. Need for Research: Modafinil has been shown to be useful for fatigue and sleepiness in patients with depression, multiple sclerosis, Parkinson's disease and individuals with EDS secondary to a variety of sleep disturbances. However, there has not been any controlled evaluation of Modafinil use for the treatment of individuals with TBI to date. Current and Future Research Activity: Approximately 60 participants with post-TBI fatigue will be randomly assigned to two 10-week periods of taking either Modafinil or placebo. Participants taking Modafinil during the first 10 weeks will be switched to placebo for the second 10 weeks. Similarly, participants taking placebo during the first 10 weeks will be switched to Modafinil for the second 10 weeks. Outcomes relating to fatigue and EDS will be collected weekly throughout the study. Other outcomes (including general health, depression, and cognitive function) will be collected at the start of each period, 4 weeks into each period, and again at the end of each period. It is hypothesized that participants taking Modafinil will report significantly less fatigue and EDS, report significantly better general health and depression scores, and perform significantly better on tests of cognitive performance in comparison to participants taking placebo.
