Dr. Ray Dorsey with a molecular model of trichloroethylene (TCE), a degreasing chemical linked to increased Parkinson’s risk.

Dr. Ray Dorsey, director of the Center for Brain and Environment at the Atria Health and Research Institute, visited the Bay Area in January 2026 as part of his national book tour for “The Parkinson’s Plan,” (pdplan.org), co-authored with Dr. Michael Okun. Stanford’s APDA Information & Referral Center hosted Dr. Dorsey at two local venues.

Two leading stem cell researchers shared updates on clinical trials for Parkinson’s Disease (PD) in a January 2026 webinar hosted by the American Parkinson Disease Association (apdaparkinson.org). Dr. Jun Takahashi detailed results from Japan’s induced pluripotent stem cell (iPS cell) transplant trial, while Dr. Claire Henchcliffe discussed her work on stem cell trials using both embryonic stem cells and personalized iPS cell approaches. This webinar and these notes are of interest to anyone curious about where stem cell research stands and what’s involved in these experimental treatments.
