And how long ago was that initial research done?

That was about 20, 25 years ago that it became known as CTE.

But people have been studying this since the 40s, since the 1940s.

It's just, I think, actually hit the nail on the head there with how you described it as these high profile athletes that have been diagnosed.

And that's been getting a lot of media attention.

Because when, for example, an NFL player dies, or donates their brain or is confirmed to have CTE, that makes big news.

But for example, military veterans, which is in a crisis situation right now, there's two deaths by suicide in the U.S. alone from military veterans.

Is there, before we let you go, is there a story you can share about a patient you've worked with or someone who is just so grateful that this work is happening?
