Covid-19 and Neurological Disorders

COVID-19 disease was accepted as a pandemic by the World Health Organization in 11 March 2019. At the earlier period of the pandemic, it was first recognized as a viral infection that affects the respiratory tract and causes severe acute respiratory failure (SARS). Over time, it has been demonstrated that it affects other organ systems, primarily vascular systems, and most importantly, neurological systems together with other systems, and sometimes even only neurological systems. Loss of smell is common even in patients without serious symptoms, and may be the first or only symptom in some patients. Failure to regain the olfactory function as rapidly despite the recovery of viral infection is an important neurological involvement affecting the quality of life. During the pandemic process in the world, fast information flow continues with case reports and analysis of clinical data. In this article, it is aimed to share current information about cranial nerve involvement, cerebrovascular diseases and stroke, encephalitis, epilepsy, Guillain Barré syndrome, and psychiatric disorders in the light of neurological involvement reported in the world with a literature review.
