There`s three sort of fundamental things that happen when someone`s suffering from these issues [post-traumatic stress disorder ]. First, they get intrusive thoughts.The second issue is you become startled quickly.And the third key point is it`s avoidance.Those are the three sort of pillar fundamentals of what we consider post-traumatic stress, not violence against someone who`s close to you. There`s just a huge misunderstanding.

I was shocked [of Sarah Palin ], because beating up, you know, your girlfriend, your spouse, or acts of violence aren`t one of the core symptoms of post-traumatic stress disorder.

She [Sarah Palin] doesn`t quite understand the issue [post-traumatic stress disorder] and, you know, if she`s going to continue to be in this space, hopefully she can do some homework and make some policy recommendation that are relevant to fixing the problem.

I think if we really break it down and talk about post-traumatic stress disorder, it`s very different than the way Sarah Palin explained it.

I think that Sarah Palin really missed the chance to educate the public on what some of the challenges her son is actually facing.
