In this Science Snack, Dr. Suzanne Rutherford explores what the evidence says about exercise, mild cognitive impairment (MCI), and dementia. She breaks down why some of the popular claims around exercise and dementia prevention aren’t as clear-cut as they seem, and where the research is much more promising.

We explore the evidence supporting exercise for people with MCI, including the roles of cardiovascular and resistance training, how much exercise appears to be beneficial, and the important limitations of what exercise can and cannot do.
