By its nature, a stroke is manifested in violation of circulation of the brain (acuteform), which lead to irreversible damage to the blood vessels and tissue necrosis of nerve fibers.

Due to the occurrence, stroke is of two types:

- hemorragichesky in which there is mechanical damage (rupture) of the vessel. The reason for the gap artery aneurysm can be high blood pressure.

Any irregularities in the individual organs or systems due to stroke, are caused by necrosis of nerve cells in the brain that are responsible for the operation of theseorgans and systems (limb movement, speech, vision, etc.). The seriousness of the consequences depends on how big is the damage to the brain and how timely and properly was given first aid (well, further treatment). Among the most common are isolated:
