Post-acute SARS-CoV-2 infection is associated with specific brain MRI changes (thalamic T2* signal, white matter diffusivity) and impaired executive/visuospatial cognitive performance, which correlate with the severity of the initial inflammatory response.

If you are experiencing 'brain fog' or difficulty with planning and spatial tasks after COVID-19, it may be linked to structural changes in your brain. Consider a neuropsychological evaluation to assess cognitive function, as these deficits are common and may require specific cognitive rehabilitation strategies.

GoodSupportsHIGH confidence
Patients exhibited changes in the thalamus, posterior thalamic radiations and sagittal stratum on brain MRI and demonstrated impaired cognitive performance, specifically in the executive and visuospatial domains... Periventricular white matter hyperintensities (pWMH) and right thalamic T2* correlated with white cell count... in patients.
