tght althouBefore I begin,please understand I write entirely from my own experience,a reading of my medical notes and brief glimpses into what experts are saying about onet of delirium re Parkinson’s patients. I have no medical knowledge and much of what I say is mere opinion.
I guess that your your father’s delirium is more related to a disruption in his drug routine than a result of having dementia and that although his bodily needs are being met as far as possible, the turmoil within his mind, is ignored, because the hospital staff have no resources to draw on.
Your father is terribly bewildered and frightened. He is in unfamiliar surroundings, attended by people he does not know, handled in ways he does not understand, separated from those he loves. He can be jikened to a frightened animal. He is crying for help. How deep his agony is or the depth of his suffering we cannot know - but we’can be certain that what he needs most is assurance of your love and your understanding. It s essential that you remain calm and in control and that you keep a careful watch on the way he is being handled and treated during his stay.
‘The best place for him is to be at home and , if all possible, this is what you should be aiming at. There are avenues to explore and ways of going about this which I cannot advise you of in this posting. I hope this is of some help to you.
