Stroke (insulto - leap, lat.) - acute violation of cerebral circulation. Every 1.5 minutes in Russia someone gets a stroke. 80% of patients become deeply disabled if assistance has not been provided at the time. Stroke, as a rule, is not a rapidly developing disease. This is a long process, going through stages from minor functional changes to irreversible structural damage to the brain - necrosis (necrosis of brain cells). This severe disease is a consequence of the violation of the function of blood vessels, and the emerging neurological disorders experts call cerebrovascular diseases (from cerebrum - the brain, vascularis - vascular, lat.). The severity of the consequences of a stroke depends on where in the brain there was a violation of blood supply or hemorrhage. Each area of ​​the brain is supplied with certain blood vessels. For example, if there is a blockage of the blood vessel in the area responsible for the movement of the muscles of the left leg, then this leg is likely to be paralyzed. Violation of the functions is more pronounced immediately after the onset of a stroke. However, then they are partially restored, because although some of the brain cells located in the "epicenter" of the disorder have died, others are only partially damaged and, if they are treated correctly and urgently, they will be able to recover and carry out their work.
