Stroke is a type of disorderblood circulation in the brain and spinal cord. As a result of this disorder, insufficient amounts of oxygen and nutrients are delivered to the nerve cells, which leads to the development of pathology. As a rule, nerve cells die after a stroke, and it is not possible to restore them.
By the nature of circulatory disorders are distinguishedthe actual stroke, the cause of which is the rupture of the blood vessel due to too high blood pressure. The second variant of the development of events is a heart attack, which is most often caused by a blockage of the blood vessel, for example, cholesterol plaques or detached microthrombi.

When the visual centers are damaged, a person either ceases to see at all, or visual amnesia develops. That is, he can see, but do not recognize familiar faces or familiar surroundings.
