Well, now you're being deliberately obtuse, didn't bother to read the link, or perhaps both. The link I posted above compared the symptomology of COVID-related brain damage to moderate TBI. As the American Association of Neurological Surgeons says at https://www.aans.org/Patients/Neurosurgical-Conditions-and-T... :

> Patients with moderate head injuries fare less well. Approximately 60 percent will make a positive recovery and an estimated 25 percent left with a moderate degree of disability. Death or a persistent vegetative state will be the outcome in about 7 to 10 percent of cases. The remainder of patients will have a severe degree of disability.
