Stroke is a brain blood vessel
disease that is characterized by the destruction of brain tissue called
cerebral infarction. Brain tissue damage occurs due to reduced blood flow and
oxygen due to narrowing, blockage or rupture of blood vessels of the brain. So
there are two kinds of stroke, i.e. damage to brain tissue caused by blockage /
constriction (infarction) and cerebral blood vessels due to bleeding
(bleeding).
The stroke disease is characterized by the presence of stroke symptoms decreased nervous system function caused by cerebrovascular disease and not by other reasons. Stroke is divided into two types: ischemic stroke (infarction) and stroke Hemorrhagic (bleeding).

Ischemic stroke is blockage of blood
vessels that cause blood flow to the brain in part or whole stop. The majority
of stroke cases are ischemic stroke, ischemic stroke can occur because of clots
/ blood clots that block blood flow to the brain as well as reduced blood flow
to the brain due to thrust a weak heart.
Hemorrhagic stroke is a stroke
caused by rupture of blood vessels of the brain. Serine hypertension causes
this type of stroke.
There are 2 types of hemorrhagic
stroke, namely:
- Hemorrhagic intraseberal: bleeding that occurs in brain tissue.
- Subarachnoid hemorrhagic: bleeding that occurs in the subarachnoid space (a narrow space between the brain surface and the layer of tissue covering the brain).
