Cerebral Vascular Crisis

**Cerebrovascular crisis** or **cerebral catastrophe** is an acute deterioration in condition associated with acute diseases of the cerebral vessels (the causes of which are usually atherosclerosis, hypertension, pathology of heart rhythm and respiration). There is also a cause associated with peripheral disturbances of cerebral blood flow due to their damage by various exogenous and endogenous factors (for example, acute head injury, influenza, encephalitis, as well as during surgical interventions). A characteristic feature of such crises is a clear provoking onset, while there are no longer any reasons for the development of coronary pain. Also, one of the characteristic manifestations of cerebral crises are diffuse headaches. In addition, cerebral vascular crises occur with other symptoms caused by cerebrovascular accidents.

**Cerebrovascular crisis** - acute or subacute damage to blood vessels and nearby tissues in the brain associated with an increase in blood pressure or venous pressure, a sharp change in blood pressure or blood volume due to any underlying disease. The classification is based on various factors that determine the type of cerebrovascular accident. According to the mechanism of development: * perivascular strokes (impaired blood flow through the vessels of the brain); * lacunar strokes; * cardioembolic strokes.

Cardioembolic (stroke) is associated with a blood clot that migrates from the atrium of the heart into the arterial system of the brain. As a result of such an event, a partial or complete cessation of blood flow through the affected vessel occurs, which leads to disruption of the functioning of parts of the brain and the development of a stroke. This type of pathology is the most common among all causes of cerebroventricular crisis. Cerebral strokes can be caused by a variety of factors, including excessive alcohol consumption, smoking, high blood pressure (hypertension), abnormal blood sugar levels, low cholesterol, hormone imbalances, brain injury, inflammation, exercise, older age, metabolic disorders substances and other diseases. Cerebral hemorrhages can lead to the death of nerve cells and permanent brain damage. They often occur against the background of hypertension, atherosclerosis and other diseases of the cardiovascular system.
