How does PTSD affect the brain?

Answer 1

You can forget the event that caused the disorder or you may forget everything that happened before it.I have PTSD and my memory has been effected and i don't remember anything that happened before the event, i remember what happened tho, i have nightmares every night and i also have replays in my head all the time, PTSD has a different effect on everyone, i have been effected really bad, and its not easy having the disorder. But yeah... that's it really, you just forget things that happened before and some people forget the event all together.

Answer 2

Post-Traumatic Stress Disorder most likely affects many different regions of the brain but two areas in particular seem most involved. The amygdala helps transmit signals regarding physical and chemical responses to threatening information from the environment. The hippocampus provides the link between with amygdala and the cortex and is particularly important in memory, indicating that the hippocampus may be involved in helping the amygdala transmit the signals for the correct responses to certain constellations of environmental cues. Together, PTSD affected amygdalas and hippocampuses result in what would normally be nonthreatening environmental inputs being linked to traumatic memories, resulting in disproportionate and irrational responses to everyday occurrences.
