(along w/ cold to touch) Dad is 70, with early onset, rapid decline (4 yrs since dx while in Stage 1) Alzheimer's. He's currently stage 6/7 (near-constant aspiration, dual incontinence, difficulty w/ words but knows Mom & I by name & relationship). This morning Mom mentioned that he was disoriented and weaker than normal. I asked her to check his temperature (knowing that infection can bring on both), says he's ice cold on extremities. Any suggestions?
