Patterson's illness was exposed at a hearing for the WBO i believe when he could not remember basic details in his life which was sad to hear.

Another story I read about him was that when he retired from boxing he went to the doctor because he felt unwell and the doctor basically said that he has been used to training all his life and because he has stopped that was the reason for feeling unwell and told him to stay in shape.

KO'ed Cooper and Ingemar Johansson clean, leg was quivering.
