| The COVID-19 pandemic might feel like a distant memory, but for many, a disturbing symptom remains: brain fog. Forgetfulness, muddled thinking, and fatigue are some of the neurocognitive symptoms that can linger long after the initial infection clears. In a new Special Feature, we report on the latest research into why COVID-19 has this effect on the brain.
The evidence suggests that SARS-CoV-2, the virus responsible for COVID-19, might not entirely disappear after a person recovers. Lingering traces could provoke a chronic, low level immune response within the body that can subtly disrupt brain function. “The cognitive impacts of long COVID are very real, and potentially quite concerning,” says Dr. Giovanni Schifitto, professor of neurology at the University of Rochester Medical Center, NY. “The changes we’re seeing in brain scans suggest that, for some people, COVID-19 infection could have consequences lasting far beyond the initial illness.” As researchers continue to seek answers, targeted treatments for brain fog remain elusive. In the meantime, doctors advise that healthy habits, such as balanced nutrition, regular exercise, and adequate sleep, might offer some support. Avoiding mental and physical overexertion is also important, as this may exacerbate long-COVID symptoms.
