That's a tricky question. Most aging experts feel that if you live long enough, you will eventually experience some dementia
. So the real question should be, "Can you do anything to delay the onset and progression of dementia?" And to that question, the answer is, "yes." Things like exercise, a good diet, multivitamins and antioxidants
, ongoing mental stimulation (reading, puzzles, self-improvement programs, etc.), sound management of stress
, etc., have all been shown to delay dementia.
