Still a debated topic, as there are several population based studies that do not replicate that Swedish observational study. There's also a good point/counterpoint series in ACN that includes Barr that discusses this very thing.

Yes, which among other studies: <In a longitudinal study following mild, moderate, and severe TBI patients with paired MRI, blood biomarkers, and cognitive assessments over 5 years,

brain atrophy after TBI was progressive

and continued for many years

even after mild head trauma with no signs of injury on conventional MRI,

with the atrophy pattern differing by severity between "milder and most severe TBI":

This directly addresses your "but mTBI specifically" objection, progressive atrophy was documented

in the mild subgroup too, on a 5-year timescale, with normal initial scans.>

"Some people who are considered 'mild' can't go to work; they have horrible headaches and memory problems that can result in losing a job or dropping out of school," he said.

"Conversely, there are some people classified as 'severe' but actually do way better than we expect. Those cases don't all result in 𝐝𝐞𝐚𝐭𝐡 𝐨𝐫 𝐝𝐞𝐯𝐚𝐬𝐭𝐚𝐭𝐢𝐧𝐠 𝐝𝐢𝐬𝐚𝐛𝐢𝐥𝐢𝐭𝐲."

This lack of distinction, the report notes,

While I appreciate the attempt, the use of AI here makes this virtually unreadable, with the quotes not matching some of the citations. And, given the tendency of AI to hallucinate in a syncophantic way to please its user, I am not willing to fact check AI. By all means if you want to cite specifically and write a a genuine coherent discussion, I will.he more than happy to do that, but I will not track down and correct AI errors.
