More Evidence COVID ‘Brain Fog’ Is Biologically Based

Patients with persistent cognitive impairment months after illness with mild COVID-19 have higher levels of inflammatory markers in their cerebrospinal fluid (CSF).

Researchers found elevated levels of CSF immune activation and immunovascular markers in individuals with cognitive post-acute sequelae of SARS-CoV-2 infection (PASC). Patients whose cognitive symptoms developed during the acute phase of COVID-19 had the highest levels of brain inflammation.

The findings add to a growing body of evidence that suggests the condition often referred to as “brain fog” has a neurological basis, said lead author Joanna Hellmuth, MD, MHS, assistant professor of neurology at the University of California, San Francisco Weill Institute of Neurosciences and the UCSF Memory and Aging Center.

The findings will be presented at the American Academy of Neurology (AAN) 2022 Annual Meeting on Thursday.
