For years, scientists have been trying to pinpoint the factors involved in the mental decline associated with age and a recent study may have offered a hint, according to AARP.org.
At a recent American Chemical Society conference, molecular biologist Shibu Poulose hypothesized that, as the brain ages, its ability to keep biochemical debris from accumulating is reduced and, as these compounds build up, cognitive function is affected.
However, Poulose and other scientists have recently found that the extracts from berries actually help the brain retain these house-cleaning processes, so that the debris is cleared and the brain is kept clean.
"Most of what goes on in the aging brain is a damaging buildup of debris, and it can be removed. It's never too late to start eating berries," neuroscientist Paula Bickford told the news provider.
Berries such as frozen or fresh strawberries, blueberries, acai berries and other colored berries have been shown to have beneficial and protective effects on the brain.
Older adults who are interested in keeping healthy and independent may also want to invest in a personal emergency response system. This device can allow seniors to immediately contact loved ones or physicians in the case of an unexpected medical complication.
