| 0:19.8 | And according to a study published in the Lancet, the numbers could double |
| 0:24.3 | again by 2040. The onset of Parkinson's disease can have devastating consequences for individuals |
| 0:32.0 | and for families. And today, I am so grateful to have the world's leading expert in Parkinson's, both to share |
| 0:41.7 | why these skyrocketing rates are taking place and also to talk about the science-backed solutions. |
| 0:50.3 | As things are going right now, it's going to be rare to find someone who is not connected |
| 0:55.7 | to someone who's experiencing the ramifications of Parkinson's disease or experiencing it |
| 1:01.3 | themselves. We've got to turn this ship around. And I'm so grateful to share this episode |
