At diagnosis, and once a year thereafter, everyone worried about Parkinsonism should get some lab testing done. We've been following hundreds of people for several years, and we can see which biomarkers are associated with faster and slower progression. All labs discussed are available, affordable, modifiable, and associated with fewer PD symptoms over time. By testing blood, urine, hair, stool, etc. - we can identify metabolic perturbations and help you correct them.
