New research adds to the evidence on the brain-protective power of exercise. In a long-term study, a group of nearly 200 middle-aged women took an exercise test that measured their peak cardiovascular capacity and were rated as having a high, medium, or low level of fitness. They then received periodic evaluations for dementia over several decades. Over the course of 44 years, only 5 percent of the highly fit women developed dementia, whereas 25 percent of moderately fit women and 30 percent of those with a low fitness level did. In other words, the most fit women were nearly 90 percent less likely to get dementia than the least fit women. This study didn’t prove that exercise helps to prevent dementia, but it’s one of many showing a strong link. Carve out a half-hour for cardio a day, most days of the week, and work in a few weekly strength-training sessions.
