Post-Traumatic Excessive Daytime Sleepiness in the Elderly
Traumatic brain injury (TBI) is a significant cause of disability in the United States with over one-half million Americans being affected annually. A recent uncontrolled study by one of the investigators in young adults with post acute brain injury (mean age 32 ± 11 years, time from injury > 3 months) found that 47% had excessive daytime sleepiness (EDS) as objectively measured with the multiple sleep latency test (MSLT). Compared to the US population, these hypersomnolent subjects had a high prevalence sleep disorders associated with EDS. The overall goals of this research proposal are to strengthen these findings by using a more robust case-control design, and to extend these findings to older adults (age 50-75 years) with post-acute traumatic brain injury.
