My Dad’s vascular condition has changed quite a bit in the last few days. He was diagnosed in 2015. I was able to take him out and about, was going to a day centre, managed a 400m walk with assistance last week. His blood pressure etc have never really been a issue or any other risk factors. Is very sleepy, not very responsive, agitated if moved, his eyes are droopy. He is taking food and drink if given to him. He is pretty lifeless. Could this possibily be a silent stroke or a UTI? The Dr recommended antibiotics to start with, then possibly bloods. Said it wasn’t really in is best interests to go to hospital for a scan. Is not having a scan standard practice?
