[|Human|] My son was hit in the head three years ago with a tree limb causing his first seizure. Now at age 38 he doesn t use but can his right hand. He just recently went to the doctor an they diagnosed him with having MS. However then sent him to a neurologist an he diagnosed him with Corticobasal ganglion degeneration I feel like he had a stroke an it went undiagnosed.
[|AI|]  I read your question and I understand your concern. To be honest I am very puzzled by your story, especially the corticobasal ganglion degeneration (CBG) part. CBG typically presents around the age of 60. The youngest ever documented case has manifested at the age of 34 (I rechecked before answering just to be sure). So if your son had that disease at 38 with manifestations starting at 35, he would be an almost unique case in the history of the disease, I would be really careful in taking that diagnosis. As for the distinction between MS and stroke related to the head trauma it should generally be easy with an MRI if history and examination do not already make that distinction. Without knowing more about the signs and MRI report it's hard for me to say something more because these diseases can have many presentations. The seizure would direct more towards the head trauma rather than MS, as would the fact that the deficit has remained constant in time since the hit, without new signs, as you seem to suggest, but as I said MRI and more details are needed. I hope things work out for the best.
