I am in deep sadness over what has happened to Lee, and I feel for his family, especially Kristin.
I can't help but draw parallels between this story and Flowers for Algernon. It's just sad to see such a young brilliant mind be broken down by this disease.
I wasn't expecting him to be diagnosed with FTD, I will admit that reading the first part of the article painted a very different picture of what might be causing his issues.
Also, since he had a heart condition, I wonder if for some reason that might have accelerated his condition?
