> In short, mild cases of COVID may cause these changes in brain tissue because the virus disrupts normal NVC [neurovascular coupling, a mechanism for supplying brain tissue with nutrients] in the hippocampus and surrounding areas. In turn, this may block the process of neurogenesis and lead to brain shrinkage and progressive cognitive decline and short-term memory loss. The same tissue damage can be detected in aging patients and those with neurodegenerative disorders (such as Alzheimer’s disease) or traumatic brain injuries. COVID-19 produces seemingly treatable brain damage, similar in symptoms to people with Post-Concussion Syndrome (PCS). Treatment with protocols for Post-Concussion Syndrome seem to help.
