How Alzheimer's genes and past trauma relate to early memory problems in veterans

Early Cognitive Impairment as a function of Alzheimer's Disease and Trauma

['FUNDING_OTHER'] · VA BOSTON HEALTH CARE SYSTEM · NIH-11264797

This project looks at whether Alzheimer's-related genes plus combat, PTSD, or head injury are linked to early thinking and memory problems in older U.S. veterans.

What this research studies

Researchers are using health records and genetic data from the Million Veteran Program to identify cases of mild cognitive impairment and dementia among veterans. They will compare veterans with and without combat exposure, PTSD symptoms, and head injuries and analyze how those exposures interact with Alzheimer's-related genes such as APOE. The team will run genome-wide genetic analyses and gene-by-environment tests to find combinations of genes and experiences that raise dementia risk. Findings will focus on veterans across midlife and older ages to pinpoint who may show earlier signs of cognitive decline.

Who could benefit from this research

Good fit: Ideal candidates are U.S. veterans enrolled in the VA system—especially those aged 45 and older with a history of combat, PTSD, or head injury who have VA medical records and genetic data.

Not a fit: People who are not veterans, or who do not have VA medical records or genetic samples in the Million Veteran Program, would not be able to participate or directly benefit from this project.

Why it matters

Potential benefit: If successful, this work could help identify veterans at higher risk for early cognitive decline so they can get earlier monitoring, support, or prevention trials.

How similar studies have performed: Previous studies have linked traumatic brain injury, PTSD, and variants like APOE to dementia risk, but large-scale genome-wide gene-by-environment analyses in veterans are relatively new.
