It has recently become known that in case of mild memory problems that can later lead to Alzheimer's disease, it is necessary to do aerobics and even weightlifting. Canadian scientists have found that lifting weights, that is, intense physical activity, improves such indicators as the ability to resolve conflicts, attention and memory in people with moderate cognitive impairment. The study involved women of various ages, and its results were presented at the International Conference on Alzheimer's Disease in Vancouver, Canada.
