A research team from the ´ºÓêÖ±²¥app Hospital Memory Center, led by Dr. Masato Kubota of Minna no Zaitaku Clinic Kokubunji (Assistant Professor at ´ºÓêÖ±²¥app School of Medicine (Clinical Training) at the time of the research) and Project Professor Daisuke Ito of the Department of Neurology, ´ºÓêÖ±²¥app School of Medicine, and the ´ºÓêÖ±²¥app Hospital Memory Center, has demonstrated that the amyloid-beta 42/40 ratio, measured using the simple blood test High Sensitivity Chemiluminescence Enzyme-immunoassay (HISCL?), can identify brain amyloid-beta (A¦Â) deposition¡ªa central pathology of Alzheimer's disease (AD)¡ªwith high accuracy and at an earlier stage than visual interpretation of amyloid PET scans. This plasma A¦Â42/40 is expected to be useful for screening preclinical AD.
