Prof Jack Lambert: 'Brain fog' the most persistent symptom of long Covid

At our long Covid clinic in the Mater, we became aware that the heart and the lungs repaired themselves, but that Covid also affected the brain, where the damage persisted, writes Professor Jack Lambert, consultant in infectious diseases at the Mater hospital

In the first wave of Covid-19, with the original virus, it appeared the lung and heart would be the targets of damage. 

Following the establishment of the long Covid clinic at the Mater in June 2020, we became aware that the heart and the lungs repaired themselves, but that Covid also affected the brain, and this is where residual damage persisted, and that some people, even a year after infection, had residual symptoms.
