Overview

Over 50% of the Veterans enrolled for VA health care are over the age of 65. Dementia prevalence increases with age, and with the increase in the population of people ages 65 and older, the total number of people with dementia is also increasing. Older Veterans often have comorbid PTSD, major depression and traumatic brain injury so that they are at 2 to 5 times the risk for cognitive impairment and dementia compared to the general population. There is evidence that exercise interventions in sedentary older adults could improve both physical and cognitive function. However, there have been very few studies on the effects of exercise on cognition in older Veterans and do not reflect the broader ethnic and health-status diversity of Veterans. Thus, improved knowledge of the role of exercise on cognition as well as the predictive power of biomarkers could have a major beneficial impact on Veterans' functional independence and quality of life. The investigators hypothesize that participation in the VA Gerofit exercise program will improve cognitive function in older Veterans and that blood and muscle biomarkers will predict these improvements.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
