Alzheimer's Association International Network to Study Chronic Neurological Sequelae of SARS-CoV-2

Scientific leaders, including the Alzheimer’s Association® and representatives from around the world, including six continents, are working together with technical guidance from the World Health Organization (WHO) to track the long-term impact of SARS-CoV-2 (also known as novel coronavirus, COVID-19) on the brain.

The impact of SARS-CoV-2 on the brain

The ongoing pandemic of SARS-CoV-2 has focused global health care resources on treating affected individuals and preventing the further spread of the infection. Although relatively little is known about the long-term consequences of SARS-CoV-2 infection, there are several research studies to suggest that COVID-19 is associated with neurological complications. The downstream impact of COVID-19 on the brain is not well understood. There are many unanswered questions regarding the effects of SARS-CoV-2 on the cerebrovascular system (e.g., blood-brain barrier integrity), the brain's immune response and more.

About this network

Scientific leaders, including the Alzheimer’s Association and representatives from more than 25 countries around the world, including six continents, — with technical guidance from the WHO — formed an international, multidisciplinary consortium to collect and evaluate the short- and long-term consequences of the viral infection on the central nervous system, 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.
