I clearly recall back in the late 60s when I was taking college courses in nursing that one of the best things to help your brain recover better if you experience a stroke is to use you non-dominant hand for every day activities. Writing was one. This is one thing I practice often.
This too can be an exercise that veterans who have had TBI can practice to overcome the problems they have to deal with daily. It can help PTSD and aphasia too.
Now here's that suggestion again, 42 years later.
Use your non-dominant hand: If you’re right-handed, use your left hand to eat, comb your hair, brush your teeth, write your name, or try putting your mouse pad on the other side of the keyboard. This practice of non-dominant hand use stimulates communication between the two hemispheres of the brain, helping to improve mental capacity as well as physical balance. Another idea: tai chi and yoga are physical activities that coach people to use the right and left side of the body equally.from Easy Exercises to Keep Your Brain in Shape
