Survivors of SARS-CoV-2 infection often suffer from “brain-fog”, a general degradation of cognitive abilities. This condition shares similarities with the “chemo brain” symptoms experienced by patients after or during cancer treatment. Mice infected by SARS-CoV-2 in the nasal cavity and presenting only mild COVID-19 symptoms had an elevated cytokine profile in the cerebrospinal fluid. Elevated levels of CCL11 in the brain caused by dysregulation of oligodendrocytes resulting in myelin loss. Both “COVID-fog” and “chemo-fog” share pathophysiological similarities in the multi-cellular dysregulation.
