3 Brain Myths

Can crosswords prevent dementia? Does mental sharpness inevitably decline as you age? Recent research is challenging long-held assumptions about the older brain and pointing to ways to support brain health. Check out these three myths — and myth-busting facts.

Myth 1: Doing brain games, like crossword puzzles, will slow mental decline.

Fact: Games and puzzles are wildly popular, but evidence that they reduce the risk of dementia is “weak to non-existent,” says a report by AARP’s Global Council on Brain Health. That doesn’t mean games are a waste of time, though. They may sharpen some skills — especially if you challenge yourself with new types of games or other stimulating projects. Plus, they can be a fun diversion!

Myth 2: The brain is hardwired to decline with age.

Fact: The brain’s plasticity — its ability to change and adapt — continues throughout life. While certain skills may decline, others may improve. Nerve cells in the brain’s hippocampus, important for learning and memory, may keep growing into a person’s late 80s, in fact.

Myth 3: Diet and exercise are good for the heart but don’t do much for the brain.

Fact: Habits that are good for the heart are good for the brain, too, research shows. For example, eating a Mediterranean diet — which is heavy on fruits, vegetables, whole grains, beans and olive oil and light on red meat — may protect against cognitive decline, as well as heart disease and diabetes. That’s a win, win, win.
