mark - I have to say after experiencing this, I have a new appreciation for those who suffer a brain injury. It's really hard to comprehend the nature of it if you have not been affected. It should be so obvious that damaging the organ that governs higher thinking would cause all sorts of irrational changes but it's hard to really get it to sink in unless you've walked a mile. Hopefully medical research will change all of that soon in that there will be better therapeutic devices/drugs and then who cares what people think, science will force it.
