The CDC and the AHA recommend that adults spend a minimum of 30 minutes a day, five days a week, doing moderate-intensity exercise, or at least 20 minutes a day, 3 days a week engaged in vigorous activity.
These recommendations include at least 60 minutes of moderate-intensity aerobic exercise a day, such as brisk walking, plus high intensity activity three times a week.
To reduce the risk of the disease accelerating, the recommendations included 60 minutes of brain exercises daily, 15 minutes of moderate-intensity physical exercise and avoidance of medications that might worsen the condition.
