Literally not one person here has used CTE as an excuse.
I was speaking more in terms of the general public. Literally any time an NFL player does something nowadays CTE gets mentioned (see Antonio Brown). It's annoying, it's lazy, and it's a cop-out.
Who knows how many former football players, who never even played professionally, are out there suffering from severe case of CTE.
I think what many are suffering from is depression. Here's where it gets tricky. The exact same drugs are prescribed for several different mental disorders if you will. Serotonin reuptake and serotonin and norepinephrine reuptake inhibitors (SSRI/SNRI) are commonly used for both anxiety and depression, and work for both. What I'm getting at here is this, is CTE making these people depressed and irrational, or is it simply going from doing what you love, making millions, being adored, to losing all of that and having to re-establish both yourself and your identity causing these people to struggle mentally? One's self identity is a very important thing, and for a lot of these guys, if they're not a football player, what are they?
Does your body heal CTE? Like, is a player further removed from his playing days going to show less damage than a player a few years retired?
I think the jury's still out but in my personal opinion having studied disorders of the brain to some extent, it unfortunately seems the condition is degenerative. Barring the advancement of medical technology or the perfect prescription drug cocktail the symptoms are far more likely to get worse than better. Seems to fall closer to Alzheimer's than say a concussion in that sense.
