The University of Kentucky team links long COVID brain fog to the same neuroinflammation, astrocyte activation and abnormal EEG patterns seen in dementia. The paper is a review of emerging evidence, not a new trial. The researchers want routine EEG exams for COVID survivors, an affordable test that already exists. Brain fog stops being a vague complaint once it looks like early dementia on the scan.
