There is a LOT of causal data. Autopsies of brains of Alzheimer's patients were rife with amyloid. People with mutations that caused amyloid got Alzheimer's earlier than others.
The hypothesis didn't come from nowhere.
To contrast, look at how much trouble medicine has had treating brain tumors. It has taken a long time to get effective treatments for various reasons. And Alzheimer's is way less direct in cause/effect.
