I don't want to debate mental health issues, since none of us *really* know if DG has them or not, but ADD/ADHD is a controversial diagnosis as it is. Some psychologists/case workers don't believe in this diagnosis and feel it's a result of the times of technological/information overload, people not getting outside and the exercise as humans did in the past and such so more of social/environmental factors as opposed to having to be medicated on pharmaceuticals, however, those who actually have it would probably beg to differ.
Also, strangely France doesn't even really classify or medicate it the way North America does, and they only have a .5% diagnosis rate. It doesn't really matter, just thought I'd throw that interesting tidbit in as it's interesting!

I wonder if DG was on medication and regularly seeing a psychiatrist which he should've been if he was indeed mentally ill. Wasn't that part of his probation way back when? Very curoius about this stuff.
