Would CTE vs PCS change anything ? Either way, you need to take better care of your brain. For now, it is definitely PCS. In 20 years, maybe it will be CTE.

CTE is not a progressive disease. It is a manifestation of repeatedly killing off brain cells such that brain function has deteriorated. Then age related decline kicks in and makes it worse.

I am 60 years old and have been stable for 15 years.
