I took my mom for an assessment on her walking on Monday at the ER, per her Dr.'s orders. She was admitted that night for PT assessment on Tuesday. She was cognitive, very aware and ate well. Wednesday I got a call saying my mom was in ICU. As she was getting her breakfast the nurse said her head dropped and she was incoherent. They did an MRI because they thought she had a stroke. That was negative. They have done CT Scans and an EEG. They're still looking over the EEG, and tomorrow they might do a lumbar puncture. Her numbers are perfect. Her doctors are "baffled." The ICU doctor is trying to persuade me to sign a DNR. I will not do this until I get an answer why this suddenly happened. She did know who me and my brother, sister in law and husband were. She was able to say our names, but everything else was gibberish. But she would continually make noises and turn her head back and forth. I am so confused and broken hearted. Has anyone else experienced such a thing. I am POA.
