Abstract. Stroke (acute cerebrovascular accident) is an acute condition associated with blockage or rupture of a blood vessel or venous sinus in the brain. Acute cerebrovascular accident (ACVA) is a sudden disruption of normal blood flow in the brain resulting from blockage or rupture of blood vessels. The disease is very dangerous for human health and life, therefore, when its first signs appear, urgent medical attention is needed. The diagnosis of stroke is established in the event of disturbances in the functioning of the cerebral vessels. When blood circulation is disrupted in a certain area of the brain, part of the nervous tissue dies. This can cause serious disability or death to the person. A stroke is not yet a stroke, but a condition that can lead to it. Timely adequate treatment can reduce the severity of the consequences of an attack.
