PTSD And Memory
PTSD and memory is a simple one-page guide to brain regions implicated in post-traumatic stress disorder (PTSD). PTSD has been associated with alteration in functioning of a number of brain regions including the amygdala, hippocampus, and pre-frontal cortex. The amygdala is a central part of our automatic threat-detection system and many studies have demonstrated amygdala hyperactivity in PTSD. The hippocampus is known to be essential for memory formation, but the hippocampal function is known to be impaired by extreme stress. Clients with PTSD find it extremely helpful to understand more about the function of these brain regions since it forms a key part of a rationale for memory processing therapy for PTSD.
