  • Look Inside

The symptoms of posttraumatic stress disorder (PTSD) are subdivided into intrusion, avoidance or numbing, and hyperarousal. Intrusion symptoms are phasic and avoidance symptoms are constant. Hyperarousal comprises a mixture of phasic and constant symptoms. Numerous neurobiological systems appear to be implicated in those symptoms. We discussed a neurobiological aspects of PTSD symptoms. The individuals with PTSD had failed to psychologically integrate their traumatic experiences and used dis-sociation as a way of dealing with strong affects.
