Unresolved PCS is not the same at CTE. Except in rare circumstances, CTE takes years to decades to manifest. Dr Omalu is at the head of the pack for research. A few other locations are pursuing similar research such as Boston/Harvard.

"then followed up viewing Dr. Bennet Omalu (who plays the doctor in concussion) speeches on head injuries." Will Smith plays the doctor who discovered CTE. That doctor is Dr Bennet Omalu.

There is no reason to get anxious about CTE. Your anxiety will be counter to your improvement.
