COVID-19 is the present global public health problem. This respiratory viral infection can manifest atypical presentation including neurological presentations. An important neurological problem in COVID-19 is neurovascular thrombosis. The basic pathogenesis of thrombosis in neurological system is explainable by the basic principle of thrombohemostasis.
