I'm no expert so I ask a legitimate question about PTSD and I hope the experts can answer it. Are there degrees of PTSD?
Yes, of course.
What is the criteria for authorizing a PTSD disability?
Determination by a qualified psychiatrist
Is there a point at which the V.A. admits that a PTSD patient is dangerous to himself and society?
What makes you INSIST that they are a danger to himself and others?
They might be, (unlikely but possible) but being dangerous to yourself and others isn't necessarily an outcome of PTSD.
Where did you get THAT idea, Whitehall?
