I don’t know that I would particularly expect a head injury to primarily change genes, but rather just to damage the structure of the brain itself. I don’t have any reason to doubt the study itself, but the article here is not very useful. Which genes are changed? Is it necessarily bad that genes are changed? Articles such as this are one of the reasons why people badly misunderstand (and overestimate) the effects of epigenetics.

The finding that really surprised me is that whole brain atrophy is seen ~11 months after mild and moderate TBI: https://www.ajnr.org/content/23/9/1509 https://www.ajnr.org/content/23/9/1509

The headline is wrong. > "We found many, many, many more genes were differentially expressed as a result of our early life stress manipulation than our traumatic brain injury manipulation," Judging from the rest of the comments no one else read the link either.
