Do you remember Keana McMahon? I have written about her once before. She is the former wife of deceased Pittsburgh Steelers offensive lineman Justin Strzelczyk, who met a very sad and frightening end. You can read about his last day online with a simple internet search, but it was not understood until after his brain was studied that he was dealing with the effects of CTE.
McMahon, who was married to Strzelczyk for eight years, and watched him gradually deteriorate, initially believed that it was a result of alcoholism, which he assumed that he had inherited from his father, but she realized immediately what was going on after his brain was studied.
