My brother is 65. He has had bladder cancer but is in remission. He started bleeding again during urination about four weeks ago. He has neuropathy in his feet and takes max dose of gabapetin. He stayed with us for two weeks. Noticed he drinks alcohol, talks continually, shakes, takes a lot of Xanax, hardly sleeps and has lost 70 lbs in a little over a month. He talks to himself, get agitated easily, is paranoid. He takes meds for high blood pressure and for his feet. My sister in law says he is driving her crazy. He talks nonstop, forgets and loses things so gets angry when he can t find what he misplaced. He always talks about the past and interrupts you so you can t get a word in edgewise. Lately he has been spending money like crazy and hoarding things new and from the past. Help!
