It is now clear that many patients suffering from COVID-19 exhibit neurological symptoms, from loss of smell, to delirium, to an increased risk of stroke . There are also longer-lasting consequences for the brain, including myalgic encephalomyelitis /chronic fatigue syndrome and Guillain-Barre syndrome .
These effects may be caused by direct viral infection of brain tissue . But growing evidence suggests additional indirect actions triggered via the virus’s infection of epithelial cells and the cardiovascular system, or through the immune system and inflammation, contribute to lasting neurological changes after COVID-19.
I am a neuroscientist specializing in how memories are formed, the role of immune cells in the brain and how memory is persistently disrupted after illness and immune activation . As I survey the emerging scientific literature, my question is: Will there be a COVID-19-related wave of memory deficits, cognitive decline and dementia cases in the future? The immune system and the brain
Many of the symptoms we attribute to an infection are really due to the protective […]
