[|Human|] Hello, My brother is 66 and for the past year or so, he has been falling. He uses a walker now and was told that he has damage to the nerves in his brain that control his movement. This came on extremely fast and a few of us think that his wife may be slowly poisoning him. It takes him about 10 minutes to shuffle 10 feet. Do you know of a poison that would slowly but surely take his mobility away? We are very concerned.
[|AI|]  Hi, Thanks for writing in. It might not be any poison causing his symptoms. There are many conditions that affect the brain and the symptoms start suddenly. It will help to talk to his doctor and get a brain scan done for him. There might be conditions like Parkinson's and dementia which can cause gait changes and abnormal mentation in a person who is elderly. Understanding his condition from the clinical perspective might help in guiding his treatment and slowing the progress of disease. Please have him examined in detail and request a detailed clinical report from them. Also, please know any co morbid condition that he might have including diabetes, hypertension and heart conditions that might have contributed to his limited mobility.
