What does CTE look like while someone is still alive?
A new study from Boston University CTE Center offers one of the clearest windows yet into the cognitive effects of chronic traumatic encephalopathy (CTE).
Researchers studied 33 former NFL players who later had CTE confirmed at autopsy and had completed neuropsychological testing while alive.
The findings were striking:
đź§ 63% had memory impairment
đź§ 52% had executive function impairment
đź§ 41% had language impairment
đź§ 26% had attention impairment
More advanced CTE was also associated with worse memory performance.
The study also raises an important concern: Does the NFL’s Concussion Settlement testing system accurately identify cognitive impairment?
Among the 7 players with advanced CTE (stage 3 or 4), 6 showed measurable cognitive impairment on testing—yet all 7 received the programs lowest impairment rating. That means some former players with measurable cognitive impairment may not have been recognized as impaired and therefore may have been denied settlement benefits.
The study authors note that the settlement's scoring rules differ substantially from the clinical standards typically used to diagnose cognitive disorders.
