Scientific leaders, including the Alzheimer’s Association and representatives from more than 25 countries — with technical guidance from the WHO — have formed an international, multidisciplinary consortium to collect and evaluate the short- and long-term consequences of the viral infection on the central nervous system (CNS), as well as the differences across countries on the viral impact of COVID-19. This study aims to better understand the long-term consequences that may impact the brain, cognition and function — including underlying biology that may contribute to Alzheimer’s and other dementia.
