Currently, the only way to diagnose chronic traumatic encephalopathy (CTE), a disease caused by repeated head trauma, is by posthumously examining brain tissue for signs of tau protein buildup. But a group from Boston University may have found a way to test for CTE in living patients.
McKee and her team discovered a specific biomarker in the brains of former football players. A biomarker is a measurable substance which is, in this case, found in the brain and identifies an abnormality.
This particular biomarker is called CCL11, and it’s a secreted protein the human body uses to help regulate the immune system and inflammation in the body.
As The Ringer’s Claire McNear writes, if a CTE test is easily available to players, what will that do to football? (Or indeed, what will it do to sports like soccer, boxing, skateboarding, or even skiing?)

As will, certainly, so very many, once they have the ability to see what has happened to them. They may wonder, rightfully, about the people who trained them and paid them, sometimes even as they attempted to shut down research into CTE. They may look at the league’s structure, at the lopsided contracts that rob many players of their leverage, forcing them to choose between getting back on the field or losing a paycheck (and possibly getting cut), and at how the league cycles through players like they’re nothing more than easily broken pieces on a board.
