My brother has been hallucinating for couple weeks.. He can t sleep, he hears and sees things that aren t there.. He is very ill with many medical conditions. Heart disease, severe RA, and type 2 diabetes, he is cripled and unable to walk from the RA... I ve noticed a lot of shaking in his hands that seems to be worsening.. What kind of Dr. do I need to see,, I am so worried about him dying from the anxiety!
