A fascinating new study shows that those with a meaningful purpose in life develop fewer amyloid beta brain tangles (brain plaque) that is associated with cognitive decline and Alzheimer’s disease. Furthermore, the brain tangles individuals did develop did not have as great an impact on them.

The Rush Alzheimer’s Disease Center studied 246 participants from the Rush Memory and Aging Project who did not have dementia, subsequently died, and underwent brain autopsy. Participants received an annual clinical evaluation for up to approximately 10 years, which included detailed cognitive testing and neurological exams.

It is now known that individuals begin to develop amyloid beta plaque and brain tangles in their late 30’s, even if in good health. It is sort of like wrinkles on the skin, except we could call it wrinkles in the brain. The amount of this amyloid beta plaque determines how much cognitive function is impaired or lost. This study proved for the first time that a higher purpose was not only associated with better cognitive function while alive but also with less formation of plaque.

Maintaining quality of brain function as you age is of the utmost importance to your general health and quality of life. High blood sugar, too much stress, and a lack of exercise are ways to speed up this type of brain aging. On the other side of the coin are good nutrition, consistent exercise, and keeping your mind busy – especially learning new things. It is now safe to say that having a meaningful purpose is another key to keeping your brain in a healthy condition.
