The thing with football and CTE is that football got sucked into it and it caught them a bit off guard. CTE was discovered because neurologists were looking at effects of repeated head trauma in boxers specifically. When they found some neurological degeneration, a link was formed. They then began to link other contact sports to CTE and football had the target on its back.
CTE can only be truly diagnosed at autopsy. So when a story comes out that someone living has CTE, that's not true. They may be living with a symptom of CTE, but a diagnosis is impossible until after death. As someone who has performed thousands of autopsies, the average male brain is roughly 1335 grams. Old school thought was that brains shrink over time. New research suggests that isn't true. Diseased brains shrink.
This is a serious issue with neurological health. But, it's not just football, it hockey, boxing, MMA, soccer as well. And it's not just memory issues. CTE can cause anger, depression, erectile dysfunction, dementia, Alzheimer's, ALS. Is there a solution? Not for me to decide. But the reward comes with a HIGH risk
