I never really got to explain further (or did I?) that my point in asking this wasn't to question Alzheimer's.
Of course, I know it's real. But my point was to understand how people feel about other mental illnesses in younger people. I often read where someone wants to hang someone by their toes after a crime is committed by a person claiming insanity. Yes, I know and totally believe that that defense is overused and I'm just as guilty of expressing that anger towards some killers/assailants. However, when the crime is the result of a person's response and behavior during an episode related to a mental illness, should that person be punished the same as one who acts out in cold blood? I mean, when a person is not "there" mentally, when they don't understand reality from fantasy, when they don't know what they're doing, there can still be tragic consequences. And they are at fault, to a degree, if they understand their mental illness already and fail to keep it under control (if possible).
If I pet a cat too much or go horseback riding, I know darn well that my eyes will water, itch, and puff up, I'll sneeze, and my throat will get swollen because I am allergic to cats and horses. Those are all physical responses of my allergies. I can take medicine to tame and/or stifle the histamine stimulation in my body and prevent a reaction. But if I don't, there's nothing I can do to stop my body from doing what it does when I have an allergic attack. I don't react to dogs, hamsters, rabbits, ducks

, dolphins, or snakes. I've never petted a baby seal before. But what if I did and had a reaction? I don't take allergy medicine on a regular basis and wouldn't necessarily have it with me if I ever see a seal. So am I too blame if I have a reaction which I can't control and that I didn't not expect to experience?
Same for someone with mental illness. If they KNOW they have the disease and take medication to regulate their brain's chemistry, that's good. But what about someone who's never had an episode before and therefore they are not taking any medication? What if that very first episode is the one that makes the news? What if that first breakdown is the one where a guy takes a rifle up to the top of the UT tower in Austin and fires off 200 or so rounds, killling several people down below before being killed himself? What if it's the one where the mother dangles her baby off a highway bridge before dropping the baby and then jumping herself? Do we blame them because they never had a prior episode or warning sign -- a previous suicide attempt, an outburst, whatever?
