I've taken Ibuprofen for years for my recurrent headaches, and only recently (after decades) discovered that I had two underlying issues that seemingly caused them. The first was gluten intolerance, which presented as inflammation, and apparently I was also chronically dehydrated. I cut out wheat and started drinking tons of water and the headaches, which plagued me all my life, have almost completely disappeared.

Had I not found the cause, I would still be popping Advil almost daily. Of course, my issue and solution is almost certainly vastly different from yours or any other person, but the key was finally discovering the underlying cause. That was the tough part.

All that said, the damage has been done, hopefully the dementia doesn't set in anytime soon. My mother just died this year with dementia, it was NOT an easy ride.
