In brief: Brain physiology

It is complex. The amygdala is in hyperdrive.
This leads to hyperarousal & often aggression. The medial frontal cortex of the brain is not in full gear & thus is not properly modulating affect that is limbic & amgydala driven. The hippocampus is functioning sub-optimally which effects the storage & retrieval of memories. Ptsd causes significant changes in brain physiology.

In brief: HUGE question

Researchers are asking this also, since not everyone exposed to trauma develops ptsd.
People abused as children, or who've been repeatedly exposed to life-threatening situations, are at greater risk for developing ptsd. Victims of trauma from physical & sexual assault face the greatest risk for ptsd. Also, the support people receive (or don't receive) may determine outcome & severity of symptoms.

In brief: In a sense,

Ptsd is the natural outcome of being faced with a trauma you cannot deal with at the time.
So it becomes compartmentalized.

In brief: PTSD

One biological explanation is that the traumatic event is stamped in by an increase in the neurotransmitter acetylcholine.
