My father was diagnosed with pd in 2004,over the last 3 years and with covid stopping people going out he seem to get worse faster,and also he started seeing allucinations and having psychotic episodes, which is very distressing ,is tablets were lowered and he was slowly taken off premapexul,which restricted his movement, when the hallucinations subsided he was started on a drug called antacapone along with the madapar 4 times a day which he struggled with to get much movement so they tried it 5 times a day ,he started to battle with the drugs on a daily basis to get spells of movement and when he could do things.over the last 3 months I noticed he become more detached from things,as he was unable to get any time to do things he liked to do .slowly he seemed to get depressed and started worrying all the time about silly things as he became more and more detached he wasn't sleeping at night due to worry so slept through the day and went down hill on a daily basis. He went to see his doctor and was put on a drug call quetiapine for psychotic behaviour and 3 weeks later he died ,he went into a world of is own he stopped communicating didn't want to eat or drink he also stopped going to the toilet to empty his bowls ,so was admitted to hospital for a enema and went down hill from there ,they say he was suffering from delirium, and numonia and died 5 days later.does anyone know about this drug quetiapine or was this just the last stages of parkinsons as he ad it 18 years .any comments welcome.
