Exercise helps people sleep better and feel more alert during the day, so it can promote a normal day-and-night routine for people with Alzheimer’s. It also can improve mood. Repetitive exercises such as walking, indoor bicycling, and even tasks such as folding laundry may lower anxiety in people with the disease because they don't have to make decisions or remember what to do next. They also can feel good knowing that they’ve accomplished something when they’re finished. The type of exercise that works best for someone with Alzheimer’s depends on their symptoms, fitness level, and overall health.
I'm taking Theresa for daily walks and almost every day we are driving to a doggie park. MIL absolutely loves doggie park. She plays with all dogs (on a good day we having there about 10-15 of them). Here is our short video (Theresa wears red hat and Frosty is the white doggie).
