My Dad was diagnosed with MS about a year ago. He hasn't gone to see the dr. more than once, he seems to have gotten progressivly worse. He has tried a few P.O. medications, currently is on ritilin. He has recently been arrested for a crime he confesses to and is facing 15 years in prison. Some people in my family are saying he didn't know what he was doing, the M.S. affected his brain too much. Is that possible?
