A few years ago I read an article , Mayo Institute, about a part of the brain, the hippocampus which is in thr centre of the brain. The study was about agroup of students who were cramming for their finals. Whilst doing so it was noticed that the hippocampus was shrinking during their studying. When the final were over it returned to normal. With PTSD sufferers the hippo. shrinks to point where it can not go back to its usual size. I have just searched out and discovered this bit of info, "The PTSD group had significantly smaller right (and a trend for smaller left) hippocampal volumes than the Control group. The results suggest an abnormal rCBF response in the hippocampus during explicit recollection of nonemotional material in firefighters with PTSD, and that this abnormal response appears to be driven by relatively elevated hippocampal rCBF in the comparison condition." "Recent studies have reported memory deficits and reduced hippocampal volumes in posttraumatic stress disorder (PTSD).( source NCBI) Excellent site for any MI sufferer "About six months ago I was part of a study group in the Psych Dept of UTAS and it was about two hours long and arduous, at the end of which I was shown the results, nothing I did not already know but it was helping a young lady and her thesis. Boy a bit long winded.
