I think what you're responding to is NOT about willingness to experiment with unproven drugs, but rather a feeling of horror about dementia and Alzheimer's disease. These are awful afflictions that impact not just the victims but also their families.

That said, regardless of whether or not they're proven/approved/tested, drugs are never magic bullets. The ones used to treat the most serious chronic diseases always come with serious risks and profound side-effects. I don't expect that to change anytime soon.
