Hi, my father is 80 and contracted polio when he was 17. He recently fractured his ankle in his good foot and has been in a nursing home. He has developed dementia within the last 3 weeks that has gotten to the point of not being able to carry on a conversation with him. He knows people and dates. MRI did not show significant damage to go along with actions. A neurologist has now ordered more bloodwork and is thinking this could be something else. They are doing a spinal tap tmrw and have started him on a steroid for 5 days. Have you ever heard of dementia being a post polio syndrome disease? Thank you.
