We developed a machine learning–based probabilistic method designed to assess the progression to dementia within 24 months\, based on the regional information from a single amyloid positron emission tomograp hy scan. Importantly\, the proposed method was designed to overcome the in herent adverse imbalance proportions between stable and progressive mild c ognitive impairment individuals within a short observation period. The nov el algorithm obtained an accuracy of 84% and an area-under-the-receiver-op erating-characteristic-curve of 0.91\, outperforming the existing algorith ms using the same biomarker measures and previous studies using multiple b iomarker modalities. With its high accuracy\, this algorithm has immediate applications for population enrichment in clinical trials designed to tes t disease-modifying therapies aiming to mitigate the progression to Alzhei mer's disease dementia.\n DTSTART:20171107T203000Z DTEND:20171107T213000Z LOCATION:Room 24\, Purvis Hall\, CA\, QC\, Montreal\, H3A 1A2\, 1020 avenue des Pins Ouest SUMMARY:Sulantha Mathotaarachchi\, MSc\, 91ºÚÁÏÍø URL:/mathstat/channels/event/sulantha-mathotaarachchi- msc-mcgill-282420 END:VEVENT END:VCALENDAR
