How COVID-19 Can Damage the Brain
September 15, 2020
(Nature) – In the early months of the COVID-19 pandemic, doctors struggled to keep patients breathing, and focused mainly on treating damage to the lungs and circulatory system. But even then, evidence for neurological effects was accumulating. Some people hospitalized with COVID-19 were experiencing delirium: they were confused, disorientated and agitated. In April, a group in Japan published the first report of someone with COVID-19 who had swelling and inflammation in brain tissues. Another report described a patient with deterioration of myelin, a fatty coating that protects neurons and is irreversibly damaged in neurodegenerative diseases such as multiple sclerosis.
