Risk factors for decline in cognitive performance following deployment-related mild traumatic brain injury: A preliminary report

Neurocase. 2021 Dec;27(6):457-461. doi: 10.1080/13554794.2021.2002912. Epub 2021 Nov 16.


Thorough identification of risk factors for delayed decline in cognitive performance following combat-related mild traumatic brain injury (mTBI) is important for guiding comprehensive post-deployment rehabilitation. In a sample of veterans who reported at least one deployment-related mTBI, preliminary results indicate that factors including a history of loss of consciousness over 1 min, current obesity and hypertension, and Black race were more prevalent in those with decreased scores on a measure of memory function. These factors should be considered by clinicians and researchers working with current and former military personnel.
