Try exercise to improve memory & thinking.

Will exercise be prescribed to improve memory and thinking? It's incredible how much intentional, challenging, and enjoyable activities can positively effect our lives. 

A new guideline for medical practitioners says they should recommend twice-weekly exercise to people with mild cognitive impairment to improve memory and thinking.

Dr. Petersen encourages people to do aerobic exercise: Walk briskly, jog, whatever you like to do, for 150 minutes a week -- 30 minutes, five times or 50 minutes, three times. The level of exertion should be enough to work up a bit of a sweat but doesn't need to be so rigorous that you can't hold a conversation. "Exercising might slow down the rate at which you would progress from mild cognitive impairment to dementia," he says.
