Brett Favre

The NFL legend revealed that he had Parkinson's during a US Congressional hearing in a welfare fraud case in 2024.

The former Green Bay Packers quarterback, 56, said: "Sadly, I also lost an investment in a company that I believed was developing a breakthrough concussion drug I thought would help others.

"I'm sure you'll understand, while it's too late for me because I've recently been diagnosed with Parkinson's, this is also a cause dear to my heart."
