I think this was discussed in the past, but reading this is scary. I wonder if some folks with long-COVID may have permanent damage.
COVID Tied to Changes in Brain Microstructure — Alterations seen in both long COVID patients and those who recovered from infection
COVID Tied to Changes in Brain Microstructure — Alterations seen in both long COVID patients and those who recovered from infection
The researchers found distinct brain networks that correlated with long COVID symptoms, after adjusting for age and sex. Altered brain microstructure in the mesiotemporal cortex was associated with cognitive dysfunction. Patients who had problems with their sense of smell had microstructural changes in the olfactory cortex, while those with fatigue had altered microstructure in the brain stem, including the ascending arousal network.
