If PWP have inflammation in the brain (and everything I have read suggests this is true), then why can't we just get the most powerful anti-inflammatory we have into the brain?

While we spend gazillion dollars trying to figure out how the brain's inflammatory process works, what sets it off, why it won't turn off, etc. and etc. and etc., would it be so crazy for someone to just inject cortisone into the living brain and see what happened? I know, it's too absurd...... but really, why not? I keep remembering the rhumatoid arthritis drug that was injected into the neck of those Alzheimer's patients with spectacular results. Now, I don't know if the coginitive improvement held, but something huge definitely happened, and it happened within minutes. You can't call that a placebo by any stretch of reality.

I can just see us trying to get our neuro to do this..."You guys want me to do WHAT?????" But I am serious-anyone know what might happen???
