EXERCISE CAN IMPROVE COGNITION IN OLDER ADULTS

DEAR DOCTORS: I am 82 years old, and I have tested negative for Alzheimer’s disease. But I do have some cognitive dysfunction. Can this be slowed? I exercise 30 minutes a day. In addition to that, I walk at least 1 mile. I also bicycle vigorously for two six-minute periods a day. Do you think this is helping?

DEAR READER: Changes to cognitive function are a natural part of ageing. Unlike the severe or rapid decline that signals dementia, age-related changes tend to be gradual and subtle. Minor forgetfulness is common, such as where you left your keys or a specific word you can’t recall. Executive function slows; you may find multistep tasks harder. Physical reaction time often slows down, too. This affects your ability to react and adjust to sudden changes or stimuli. Paying attention to a task or event may also feel more difficult.
