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

Scientific leaders, including the Alzheimer's Association and representatives from more than 25 countries, 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 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 study

Scientific leaders, including the Alzheimer’s Association and representatives from more than 25 countries — 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 (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.

This study will enroll two groups of individuals:

  • People with confirmed cases of COVID-19 from hospitals that have been discharged. They will be evaluated for follow up evaluations at 6, 9 and 18 months.
  • People who are enrolled in existing international research studies to add additional measures and markers of their underlying biology.
