Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The objective of this study is to measure the frequency and clinical types of mild cognitive impairment (MCI) or dementia that occur among up to 150 military retirees with and without a history of traumatic brain injury (TBI) among residents of the Armed Forces Retirement Home, Washington D.C. and the Veterans Home of California-Yountville. Investigators will compare the characteristics of dementia in those who have had a prior TBI to the characteristics in those without a history of TBI. It is our hypothesis that the dementia or MCI among those with prior TBI has distinct neuropsychological features that distinguishes it from those with dementia or MCI without a history of TBI.
