Contact Coordinator

Dr. Boxer leads this initiative that involves eight sites across North America. 4RTNI evaluates participants with primary tauopathies, including PSP, CBS, and variant tauopathy syndromes.  Additionally, 4RTNI enrolls healthy individuals.  The study will provide information about the relative value of novel imaging techniques for diagnosis, as well as the value of imaging techniques versus testing of blood and cerebrospinal fluid (CSF) ‟biomarkers.”
