Covid19 and risk of Stroke

The current Covid19 pandemic has dramatically changed the world and the way we live. The various ways in which Covid presents itself in people has not been clearly understood and new mechanisms are being learnt everyday.

One of the ways that Covid19 manifests itself is in the form of 'Stroke'. Acute Stroke in people suffering from Covid19 may present in many ways such as blockage of important arteries of the brain or bleeding within the brain. Blockage of important arteries supplying important arteries of the brain leads to acute loss of blood circulation to important parts of the brain and thus permanent damage to the brain resulting in disability or death. It has been observed that strokes in codiv19 occur predominantly in younger population than old. One of the mechanisms that is proposed to be the cause of stroke is a hyper coagulable state, which means increased tendency of the blood to clot. The exact mechanism of this hypercoagulable state is unknown, This has also led to administration of blood thinners to people affected with covid19 in the hope that the blood remains adequately thin so as to prevent abnormal clotting.

The main stay of treatment of such blockages leading to stroke is blood thinners and a procedure called 'mechanical thrombectomy', which involved extracting the clot from the area of blockage by angiography techniques. The results of treatment are good, although not as good as in non-covid patients.

Due to the widespread of the novel coronavirus, the incidence of new strokes in especially younger population is likely to increase significantly and hence it is imperative to be aware of signs and symptoms of stroke.
