![]() ![]() “We’re starting to see clear connections between COVID-19 and problems with cognition months after infection,” Erausquin said. These difficulties were associated with persistent problems in smell function, but not with the severity of the original COVID-19 disease. More than half showed persistent problems with forgetfulness, and roughly one in four had additional problems with cognition including language and executive dysfunction. Participants were studied between three and six months after COVID-19 infection. Gabriel de Erausquin, M.D., Ph.D., M.Sc., of the University of Texas Health Science Center at San Antonio Long School of Medicine, along with colleagues from the Alzheimer’s Association-led global SARS-CoV-2 consortium, studied cognition and olfactory senses in a cohort of nearly 300 older adult Amerindians from Argentina who had COVID-19. The Alzheimer’s Association and its partners are leading, but more research is needed.”Ĭognitive Impairment Correlates with Persistent Loss of Smell in Recovered COVID-19 Patients It is imperative that we continue to study what this virus is doing to our bodies and brains. “With more than 190 million cases and nearly 4 million deaths worldwide, COVID-19 has devastated the entire world. Snyder, Ph.D., Alzheimer’s Association vice president of medical and scientific relations. “These new data point to disturbing trends showing COVID-19 infections leading to lasting cognitive impairment and even Alzheimer’s symptoms,” said Heather M. Individuals experiencing cognitive decline post-COVID-19 infection were more likely to have low blood oxygen following brief physical exertion as well as poor overall physical condition.Biological markers of brain injury, neuroinflammation and Alzheimer’s correlate strongly with the presence of neurological symptoms in COVID-19 patients. ![]() Other key results reported at AAIC 2021 include: Initial findings from this consortium presented at AAIC 2021 from Greece and Argentina suggest older adults frequently suffer persistent cognitive impairment, including persistent lack of smell, after recovery from SARS-CoV-2 infection. Scientific leaders, including the Alzheimer’s Association and representatives from nearly 40 countries - with technical guidance from the World Health Organization (WHO) - are part of an international, multidisciplinary consortium to collect and evaluate the long-term consequences of COVID-19 on the central nervous system, as well as the differences across countries. In addition to the respiratory and gastrointestinal symptoms that accompany COVID-19, many people with the virus experience short- and/or long-term neuropsychiatric symptoms, including loss of smell and taste, and cognitive and attention deficits, known as “brain fog.” For some, these neurological symptoms persist, and researchers are working to understand the mechanisms by which this brain dysfunction occurs, and what that means for cognitive health long term. New research reported at the Alzheimer’s Association International Conference ® (AAIC ®) 2021, held virtually and in Denver found associations between COVID-19 and persistent cognitive deficits, including the acceleration of Alzheimer’s disease pathology and symptoms. However, questions remain about the long-term impact of the virus on our bodies and brains. ![]() Download the complete news release and abstractsĭENVER, JMuch has been learned about SARS-CoV-2, the virus that causes the novel coronavirus, since the beginning of the COVID-19 pandemic.
