My sisters boyfriend has told her that he has some sort of condition which he has inherited from his father. His father died of this condition in a care home aged about 60. The only thing she can remember is that his dad didn't know who he was by the time that he died. The bf has been tested and also has this condition.
I know there is something commonly passed from father to son, but can't remember what it is. Hoping if I can find a few 'names' it might jog her memory! Very but it would help her help him if she knew a bit more about what he is facing.
