NFL Players Divided on Taking a Test to Detect CTE in Living Brains

Chronic traumatic encephalopathy, or CTE, is a brain disease linked to repeated hits to the head, common in contact sports like football. Right now, it can only be diagnosed after death by examining brain tissue. But scientists are working hard to find a way to detect CTE in living people.

Recently, ESPN spoke to more than 30 current and former NFL players about whether they would take a test that could diagnose CTE while they are still alive. Their answers showed a wide range of feelings.

Some players, like Marcus Mariota and Malik Hooker, said they would take the test because it could give them and others a clearer picture of the risks involved in football. Others, like Joshua Metellus, worried that knowing might change how they play or feel, preferring not to take the test during their careers. Mo Alie-Cox said he wouldn’t want to know unless symptoms showed up, fearing how people might treat him differently if he tested positive.

The players also had mixed thoughts about what a positive test result would mean for their careers. Some said they would probably stop playing, like Xavier McKinney, while others said the decision would depend on how accurate the test was, how serious the diagnosis, and advice from doctors and family.

Scientists from places like Boston University and Harvard University are studying former players to find patterns in brain tests and imaging. They hope this research will one day lead to a reliable test. But so far, no test has been proven to diagnose CTE in living people with certainty.

Meanwhile, researchers warn that many symptoms linked to CTE, like memory problems or mood changes, can also come from other treatable health issues. And some players who believe they have CTE report higher rates of depression and suicidal thoughts, which makes understanding and managing these symptoms even more important.

For now, the best advice for players and anyone with brain health concerns is to talk openly with doctors, get proper evaluations, and focus on managing treatable conditions. The search continues for a living CTE test, but until then, players’ health depends on good care and support.
