My dad is in assisted-living. He struggles with dementia, we’ve never had it diagnosed but believe that it could be vascular, or Lewy body. When he gets difficult with staff, they want him to take drugs. I don’t personally like the side effects of Ativan or the antipsychotic drugs on dad. I’ve watched one Teepa snow interview with a CEO who is in the business of helping to market the drug and was intrigued. Still a bit nervous about using it because it hasn’t been tested much yet.

I think a natural course is always the best first choice before resorting to medically created drugs. I don't personally believe that the medical industry has our best interests at heart, it is HUGE money and the sicker they keep the population the more money the machine earns.
I would give it a chance, the worse thing that could happen is he has behavioral issues, which I have never heard or read happening, and it might just help.
Best of luck and do let us know what you do and how it turns out.
