Doctors say changing and challenging your mind and mental exercises is key.
The simplicity of changing it up may surprise you. Suggestions include brushing your teeth with your non-dominant hand. Turning the pictures in your house upside down to make your brain work harder. Taking a book and attempting to read upside down. Crossing your arms the opposite way you normally do. Taking your watch and switching it to your other arm for awhile. Writing your name backwards, which is a real challenge. And watching television with the sounds turned down, following the actions by the visuals only. Meanwhile, physical fitness will help the brain, too.
