COVID Brain Fog a 'True Neurologic Condition'
Impaired cognition associated with COVID-19 appears to have a biological vs psychological basis, early research suggests. Investigators found abnormalities in cerebrospinal fluid (CSF) and other risk factors, including diabetes and hypertension, present in individuals with mild COVID-19 experiencing persistent cognitive problems, often referred to as "brain fog."
@santanu There is currently no guidance on how to identify patients with COVID-related cognitive changes, said Hellmuth. "The term 'brain fog' is not based in science or medicine, but that's the most common term we use to describe this." The analysis included adults with confirmed SARS-CoV-2 infection not requiring hospitalization who were enrolled in the Long-term Impact of Infection with Novel Coronavirus (LIINC) study. Participants underwent a structured interview that covered COVID-19 illness, past medical history, preexisting cognitive risk factors, medications, and cognitive symptoms following onset of COVID-19. They also completed an in-person battery of cognitive tests.
