The American Heart Association and the American Stroke Association describe brain health as the ability to function well in various aspects like thinking, moving, and feeling.
This applies to people of all ages, but when we talk about brain health in the context of aging, there are many terms and concepts like the "brain aging gap," "brain reserve," and "successful aging" that are used to describe different aspects of brain health. These terms cover various processes related to brain health as people get older.
From a simple perspective, the term "brain age gap" refers to how the brain can look or function older than expected for a person's actual age. This idea suggests that as we grow older, our brains may experience structural changes, but they can also maintain their function and even grow in certain ways.
When we talk about successful aging, we mean a path where individuals remain healthy in both body and mind while staying socially active. This involves maintaining the brain's structure and function as we age. So, it's about having a healthy brain without obvious disease signs.
