From the article:
> It's important to note this does not change what we know about exercise's ability to protect against dementia. People who exercise more are less likely to get dementia, possibly because it maintains blood flow to the brain.
> However, once the brain has been damaged by dementia, exercise may not help prevent further damage.
- John_KZ 8y agoAfter reading the study, it seems like they just made some people aged over 70, with progressed dementia, get light exercise twice a week for 4 months. That's it. Unsurprisingly, there wasn't much of a difference. Personally I'm pissed at the way this study is presented. It makes a lot of people falsely assume that exercise is useless, while it's definitely not. Unless you have one foot in the grave and more than mild dementia, exercise is probably still good for you. In fact the study concludes nothing for longer periods or different modes of exercise, even for people this old and with dementia already onset. Sending an old man to the gym for "mild-to-moderate intensity" aerobic exercise is a bad idea in the first place.
