Hello, My father, an 86 year old man is becoming very irritable, hallucinations, & has shown signs of aggression that I feel could lead to bodily harm. He is very ill. Kidney failure and has had two strokes 3 months apart. He was recently diagnosed with Parkinson s. I would like to know what you would expect his life expectancy to be and what would be the most likely cause of his ultimate demise. He lives with his wife (not my mother ) and she seems to be in denial. I would like to see him in a care facility for his safety as well as hers. Help Thank you, Debbie
