Football Players Show Subtle Brain Differences Linked to CTE Risk
A large MRI study found that football players’ brains show minute but consistent groove differences associated with CTE risk.
The changes—shallower frontal sulci and wider temporal sulci—mirror patterns found in autopsied CTE cases.
Researchers say these subtle shifts may serve as early biomarkers for the disease, which currently can only be diagnosed after death.
The discovery opens new possibilities for tracking brain health in athletes exposed to repeated head impacts.
