Where did I say it caused CTE?
What I said was those who have CTE have other factors that can't all be put on to sport.
Like this printed on CNN website in August, This is from looking at medical records OF those with confirmed CTE.
CTE is a condition with a broad range of symptoms, and many of those symptoms are incredibly common. It isn't at all surprising that every member of a study group would suffer from at least one of those symptoms, when in fact the majority of the world's population would.
However, displaying multiple or most of those symptoms at once is a very good indicator of a deeper issue, and in this case would more than likely suggest that the individual at least has some form of severe brain damage, and given the risk factors associated with contact sport and athletes propensity to develop it, it's significantly more likely than not that that brain damage will be CTE in the case of professional combat and contact sportsmen.
This really isn't the point you think it is...
However we know you can't indentify CTE until death. Dementia being a potential sign
These 2 in particular would apply to the older players.
So that is my point about making the game safer but can't directly link it to the game alone
Yeah and it's possible to develop emphysema without ever smoking. But what are the odds of a lifelong chain smoker's emphysema being totally unrelated to their smoking habit. . .
Besides, on average the forms of dementia that are associated with substance abuse (e.g. Wernicke-Korsakoff syndrome) display differently than CTE and can be diagnosed without an autopsy. In other words it'd take a serious f**k up to confuse them for CTE, and doctors would test patients with risk factors for those conditions for them before jumping to diagnosing CTE.
BTW, the list you provided is a list of risk factors for dementia, and most of them aren't even really risk factors for dementia so much as risk factors for other conditions that can be risk factors or causes of dementia. Something tells me that your average doctor would explore the fact that a player had suffered a stroke before they jumped to CTE being the cause their dementia lol.
