Abstract
|
|
|
|
Through the recent development and supply of COVID-19 vaccines, there is a growing interest in the management of post-treatment complications of survivors after infection, rather than the COVID-19 infection itself. Complications of COVID-19 include respiratory complications, cognitive dysfunction, central nervous system disorders, peripheral nerve disorders, critical-illness related myopathy and polyneuropathy, and dysphagia. However, there are insufficient studies on the pathologic mechanisms and epidemiology associated with COVID-19 and dysphagia. By examining similar coronavirus cases and direct cases, it has been proposed that the dysphagia arises due to damage to the central and peripheral nervous systems, critical-illness related myopathy and polyneuropathy related to intensive care unit management, and intubation damage. Understanding the epidemiology and pathological mechanisms of dysphagia that occur after COVID-19 will help prevent the affliction and manage the prognosis of high-risk patients.
