i have a friend that has started running into walls, gets disoriented, and dizzy. She has no insurance so has not seen a doctor. He mother died of a brain tumor, (prob. astrocytoma or glioblastoma). But i’m also concern because she’s married to someone who has tried to hurt her , and has taken large life insurance policies out recently. Is there any poison that could cause her symptoms,or should she concentrate on the neurologic possibilities only.
