A coworker recently told me that he has ALS. He is already starting to have noticeable symptoms. I cried with him when he told me. He is in our maintenance dept and is going to hang on as long as he can. Our supervisors are working with him and helping him. A horrible disease. I hope they find a cure, or at least find a way to slow it down. He has a granddaughter who he loves so much and grieves at the thought of leaving her. He is only 54.
Here are a few studies of things that can help your friend, at least a bit:
