### input:
My husband has parkinsons. Just the last 2 or 3 yrs. it started progressing. He has dimentia with it and it has gotten worse. July 19th, he woke me up to help him get up. When I tried to help him, he could not even sit up. My son lives with us and I got him to come help and he could not stand up. We called 911 to take him to ER and they did a lot of testing and said that he had cellulitis. He had a scratch on lower part of his leg and the scab came off and we bandaged it. The home health nurse came next day and she looked at it and said it looked fine and she cleaned & bandaged it and it was the next that he could not get up. He stayed in hospital 6 days. The cellulitis healed real quick. He was sent to nursing home for two weeks skilled nursing, but he has never walked since and can not understand him talking. He also has a critical kidney function and was sent back to hospital the 14th day in nursing home and was there for about 6 days giving him fluid in his arm. I do not know what stage of parkinsons he could be in. Just wondering how I can know the stage he is in.

Welcome to Chat Doctor From the thing you told in my opinion patients having Parkinson disease have difficulty in walking it's not like they can't walk. And you told he had cellulitis also so please organic brain disorder. Please consult Neurology so that they can rule out meningitis or other metabolic causes as your husband having critical kidney as well which will cause deranged metabolic parameters so which can also cause dementia indirectly/ directly Complete health checkup with detailed evaluation is needed. Do not consider it lightly and get consultation as soon as possibleRegards Chat Doctor.
