Make sure your diet is good & healthy, and get regular exercise. Walking is good.

Supplements would likely help. B Complex (10-25mg for most B vitamins), magnesium, zinc, lutein (20mg) and fish oil are all good. Most of those, if not all, fight inflammation and help with recovery and fight fatigue.

Try doing crosswords and mental math. Both work your memory in different ways.

Do not use supplements without checking it with your doctor.
