Summary

This trial will test if consuming blueberry powder daily for several months can improve memory and cognitive function in older adults by using the brain-protective nutrients found in blueberries. Research has shown that blueberries, rich in polyphenolics, can reverse age-related cognitive deficits and improve neuronal function.

Who is the study for?
This trial is for adults aged 65-99 who can visit Brigham and Women's Hospital four times. It's not for those with blueberry allergies, recent major surgery, organ transplants, plans to move from Boston soon, dementia, severe cognitive decline or end-stage renal disease.
What is being tested?
The study tests if daily consumption of blueberry powder (20g) over 24 weeks improves memory and cognitive functions in older adults compared to a controlled powder without active ingredients.
What are the potential side effects?
Since the intervention involves blueberries which are generally safe, side effects might be minimal but could include potential allergic reactions or gastrointestinal discomfort.

Other Research
Common treatments for Traumatic Brain Injury (TBI) often focus on reducing inflammation and oxidative stress, which are key contributors to secondary brain damage. Antioxidants, such as those found in blueberry powder, help neutralize free radicals, thereby reducing oxidative stress and preventing further cellular damage. Anti-inflammatory agents work by inhibiting inflammatory pathways, reducing swelling, and minimizing tissue damage. These mechanisms are crucial for TBI patients as they help to protect brain cells, improve recovery outcomes, and potentially enhance cognitive function.
