T, thanks. I presume that you may be referring to PTSD and the subsequent effect of biochemical changes on neuroanatomy with concurrent influences on long-term emotional memory. A pet project of mine (long ago) focused on studying how moderate stressors effect cortisol/norephinephrine ratios in blood plasma and correlated to disturbances in individual circadian rhythms, inter alia.

I'm curious about the legal aspect to which you allude. Feel free to email me as we have strayed way off topic.
