I have a friend who has dementia, a healthcare provider told her to check out LION’S MANE MUSHROOMS. She did and her husband has shown remarkable improvement. I looked it up and there are some very good articles from reputable sources.
lions mane is taken by people with MS that have brain fog. It works.
I don’t have dementia (yet) but Lions Mane works for me as well — word recall and “clarity” of thinking. Taken daily, it takes two weeks to start working. Get the kind that has both types of mushroom flesh.
