My mother (77) has been diagnosed with PD for about 10 years now. Has had typical physical symptoms, over the last few years some minor signs of dementia.
Recently over a period of a few days she went from that to completely incoherent... hallucinations, and unable to walk or recognize family members for the most part. She did have a UTI the week prior to the onset of these new extreme symptoms, which was being treated with antibiotic. (doctor took her off that early when this started happening.) MRI seems to have ruled out stroke according to hospital. Does this sound like progression of disease or way too fast for it to happen this quickly? Thank you.
