As we age, our brains age too. Cognitive aging is a natural process that can have both positive and negative effects and these effects vary widely from person to person. Our brains age at different rates and in different ways.
It’s important to keep in mind that cognitive aging is not a disease. The brain changes associated with aging are part of a natural process that starts at birth and continues throughout the lifespan. While things like our wisdom, expertise and vocabulary increase with age, other abilities like processing speed, decision-making and some types of memory may decline with age.
While 87 percent of people age 65 and older may experience cognitive changes due to the normal aging process to varying degrees, there is growing hope and expectation that it’s possible to maintain cognitive health later in life, allowing people to age independently and enjoy the benefits of a fuller life.
