Authors: Kelly Servick The true prevalence of cognitive problems in COVID-19 survivors is elusive, and the underlying causes of lingering symptoms are the subject of ongoing studies. But it’s now clear that trouble thinking, concentrating, and remembering can be among the most debilitating “long-haul” symptoms and can persist for months. As more and more people seek […]
Authors: Michael Marshall How COVID-19 damages the brain is becoming clearer. New evidence suggests that the coronavirus’s assault on the brain could be multipronged: it might attack certain brain cells directly, reduce blood flow to brain tissue or trigger production of immune molecules that can harm brain cells. Infection with the coronavirus SARS-CoV-2 can cause […]
Authors: Anna Nordvig, MD, a neurologist and postdoctoral clinical and research fellow at Columbia University Vagelos College of Physicians and Surgeons How common is it for COVID-19 patients to experience persistent neurological symptoms? There are few more pressing questions that neurologists and psychiatrists worldwide must answer, but it may not be easy. COVID-19 manifests with […]
Authors: Dr. Francis Collins While primarily a respiratory disease, COVID-19 can also lead to neurological problems. The first of these symptoms might be the loss of smell and taste, while some people also may later battle headaches, debilitating fatigue, and trouble thinking clearly, sometimes referred to as “brain fog.” All of these symptoms have researchers […]
Authors: Chris Iliades, MD It is too early to know all the long-term effects of COVID on the brain and nervous system. Some people complain of headaches, memory loss and confusion after COVID. COVID-19 is a new version of an old virus called coronavirus. Most of the effects of COVID have been on people’s lungs, […]

Authors: The biostation The world has been dealing with COVID-19 for just over a year now, yet we still seem to learn more about this virus daily. It also affects everyone differently. Some who test positive are completely asymptomatic, while others have landed in the hospital and worse. Still, others have recovered from both mild […]
Authors: Tae Chung, M.D., assistant professor of physical medicine and rehabilitation and neurology at the Johns Hopkins University School of Medicine and director of the Johns Hopkins POTS Program For almost one year, COVID-19 has impacted the world and taken the lives of many people. While some survivors have fully recovered from this illness, others are still […]
Authors: Alan Mozes HealthDay Reporter One of the least understood effects of COVID-19 infection is “brain fog,” a kind of mental confusion that can take hold among seriously ill patients, sometimes lingering long after recovery. Now, a new study has spotted a possible neurological clue in the form of highly unusual cell clusters in the […]
Authors: Gary Wenk Ph.D. KEY POINTS Neurological symptoms have been observed in 80% of hospitalized people with COVID-19. Recent studies suggest that the virus has difficulty getting past the brain’s main line of defense, the blood-brain barrier. Inflammatory molecules from astrocytes underlie many neurological problems as well as brain fog. Scientists are trying to understand […]
