It’s not that it’s completely different, it’s that we have an extremely limited understanding of the brain and how things operate.
Things like CTE can only be diagnosed post-mortem, so research on those things would slow significantly (unless people who got it killed themselves like others have).
I am specifically speaking to head trauma, mental disorders, and issues with the brain. Things we don’t know how to treat or fight, that a 30 year old body would only serve to prolong the pain and decline caused by the illness.
