Mowtown, I posted this video to explain what is being considered "bipolar" which is only misunderstood when it comes to PTSD.

The physiology of PTSD is not the same as Bipolar at all. That is why it is so crucial that a patient have the chance to discuss their history. What may be considered "wrecklessness" that is often associated with Bipolar, is simply not the case, but instead an effort to find a way to reduce the "stess buildup and symptoms of PTSD" where the individual is seeking some kind of "escape or calm", but doesn't understand "why" they struggle this way.
