---> Yes I believe so, great point. I read an article where parasites even "steal" certain cells from the body and attach them to themselves like a coat, to avoid detection from the immune system, no kidding!
> Do you have the article? Please make a post, I'd be interested in reading it as I'm sure others would too.
To answer your questions about brain parasites: Yes, parasites can grow to adult stage. There have been a few famous cases published on removal of large tapeworms. Parasites can be diagnosed -- for the post part, CT Scan & MRI are best to have because not one scan can't pick up the menacing problem. I've made several posts on the Parasite Forum on brain parasites.
