Welcome to the sixth season of the Dementia Researcher X ISTAART PIA Relay Podcast. This series features interviews with ISTAART PIA committee members talking about their research, the research landscape of their fields, and the work of the ISTAART Professional Interest Areas (PIA) they represent. As we build up to the Alzheimer’s Association International Conference in Toronto, join us for daily episodes that showcase the remarkable work being done in various research fields. -- In this Relay Podcast episode, Dr Colin Groot interviews Dr Marta Del Campo, Head Fluid Biomarker Facility; Ramón y Cajal Research fellow at BarcelonaBeta Brain Research Center and chair of the ISTAART Biofluid Based Biomarkers PIA. Together, they talk about recent advances in fluid biomarkers in dementia research, and explore the growing role of plasma biomarkers, integration with clinical trials, challenges with reproducibility and diversity, and the promise of proteomics and AI. Marta also reflects on the work of ISTAART, their plans for AAIC, the value of publishing negative findings, and why ISTAART offers vital opportunities for early career researchers. -- The Alzheimer’s Association International Society to Advance Alzheimer’s Research and Treatment (ISTAART) convenes the global Alzheimer’s and dementia science community. Members share knowledge, fuel collaboration and advance research to find more effective ways to detect, treat and prevent Alzheimer’s and other dementias. Professional Interest Areas (PIA) are an assembly of ISTAART members with common subspecialties or interests. There are currently 30 PIAs covering a wide range of interests and fields, from the PIA to Elevate Early Career Researchers to Biofluid Based Biomarkers and everything in between.
