Stroke Disease
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).
Stroke Causes
Symptoms of stroke depend on the location / part of the brain becomes blocked and the vast area of the brain affected.
Based on its location in your body, the symptoms of stroke are divided into the following:
1. Central nervous systems of parts: the left and right muscle weakness or partial (hemiplegic), stiffness, decrease in sensory function.
2. Brain stem, where there are 12 cranial nerves: decreased ability to smell, taste, hear, and see the partial or total, decreased reflexes, impaired facial expression, impaired breathing and heart rate, weak tongue.
3. Cerebral cortex: decreased memory, and confusion.
There are several risk factors for stroke are suffering from the disease, both of which are preventable or not preventable. Narrowing and blockage of blood vessels is often suffered by people whose age above 40 years because of several reasons such as decreased elasticity of blood vessels and atherosclerosis. To reduce these risks it is recommended that early on we exercise, avoiding cigarettes, alcohol and avoiding obesity.
Medical risk factors, among others Hypertension (high blood pressure), cholesterol, atherosclerosis (hardening of the arteries), heart disorders, diabetes (diabetes), and a history of stroke in the family.
Behavioral risk factors, among others: Smoking (active & passive), unhealthy food (junk food, fast food), alcohol, lack of exercise, snoring, oral contraceptives, drugs, obesity.
A mild stroke often can return to normal health, but the heavy strokes often leave residual symptoms that are difficult to correct. Such as decreased movement of the arms, legs, speech pedal. Other residual symptoms can include memory loss and thinking power, depression, difficulty swallowing, and others.
