Correlation vs Causation

I suspect some folk aren’t happy unless you can present a causation chain all the way back to to the Big Bang. Thus philosophy.

Don’t you just have to show that interventions on the brain change ‘mind’? What am I missing, here? If I can show that H. pylori can cause gastric ulcers, why am I not allowed to show that syphilis can cause dementia (ethics aside, of course).
