The article kind of implies that regular exercise will slow the disease which is really not supported by the science. You really need high intensity exercise for half an hour four times per week to slow progression. That's what SPARX3 aims to prove

The only thing that has been shown in multiple studies to slow or even stop progression of PD is the right kind of intense exercise. Sadly, doctors only prescribe pills and take notes to document the decline. Vitamin B1 therapy has shown remarkable results in some people but there's no money...
