Most neuroscientists would expect TBI to be linked to regional micoglial activation. And perhaps activated GFAP-positive astrocytes. Psychosocial stress will have different effects mediated in part by the hypothalamus-pituitary-adrenal system.
There may be some postmortem RNAseq studies of humans, even small pediatric cohort, but I did not find them in PubMed. I did find this treatment approach for TBI (yes, in mice)

You’d need verified quantified early trauma, lack of possible TBI, and early death, and RNAseq processing postmortem which is a recent development. I think about it evolutionarily: if an animal was subject to significant early trauma (i.e. divergence from expected early environment), the most likely cause is early loss of a parent and no surrogate caretaker. This suggests a markedly different environment generally, and especially socially, and would warrant a significant behavior shift if it were evolutionarily possible to accomplish. It doesn’t seem so implausible to me.
