Stanford’s Ze Yang, PhD, joined the Brain Support Network local CBS/CBD support group on Sunday, February 9, 2025, where he talked about corticobasal syndrome (CBS) research. Dr. Yang is trying to identify a blood biomarker for CBS, which would be used to accurately diagnose the disorder in a living person. Currently, there are no biomarkers for this rare disorder. A diagnosis is only possible through brain donation.
Dr. Yang addressed the difference between corticobasal syndrome (a clinical diagnosis) and corticobasal degeneration (a pathologic diagnosis), CBS symptoms, how CBS is diagnosed, the fact that there is poor diagnostic accuracy, biomarkers, and why he thinks a biomarker for CBS is possible.
Dr. Yang’s slides are available (PDF)
If you have a CBS or CBD diagnosis and are willing to drive to Stanford University for a blood draw (30 minutes), please contact Dr. Yang, [email protected].
If you have a CBS or CBD diagnosis and are interested in brain donation (regardless of where in the US you live), please contact Brain Support Network.
