About a month ago, my father had surgery for a subdural hematoma. He had been getting progressively weaker, and feeling ill. He hadn't told us he had fallen. I'm reaching out for advice. He spent 3 days in ccu and then another 2.5 weeks on the rehab floor of our local hospital. He was then transferred to a rehab facility, where he has been for a week. We can see many improvements physically, but he has become very agitated and confused lately. He also is refusing to eat. Has anyone had any experience with recovery from such an injury? I understand that every case is different, but I am looking for any advice.
