Hall of Fame quarterback Brett Favre disclosed Tuesday that he has recently been diagnosed with Parkinson's disease. That puts him among the 1 million people nationwide who are living with the disease, according to the head of the Parkinson's Foundation.
John L. Lehr, CEO of the Parkinson's Foundation, said in a statement after Favre's testimony that 90,000 people in the United States will be diagnosed with Parkinson's disease (PD) this year alone. Parkinson's is a progressive nervous system disorder that affects movement.
"Scientists believe that PD is caused by a combination of genetic and environmental factors," Lehr said.
