Stroke

Stroke that has meaning english dictionary Med. Attacks the brain, usually accompanied by paralysis. The main cause of stroke is failure of blood circulation to the brain.

Stroke is divided into two kinds of:

Ischemic stroke occurs when blood flow to the brain is suddenly blocked, resulting in cell and brain tissue will die because it no longer receives oxygen and food materials from the blood. Ischemic stroke accounting for over 88% of all strokes.

Hemorrhagic stroke (bleeding) occurs when a blood vessel in the brain bursts, allowing blood to flow into the cavity in the surrounding brain tissue. As a result, cells and brain tissue will die due to no longer receive oxygen and food materials from the blood. Number of patients with hemorrhagic stroke is only 12% of stroke patients.

In general, a stroke occurs when blood flow as a source of oxygen and nutrients to the brain is blocked. The obstacle may arise as a result of a blockage or narrowing of blood vessels, or due to bleeding in the brain. Because of the shortage of supply of nutrients and oxygen, brain cells begin to die within a few minutes. The results, appearing various neurological symptoms.

Non-bleeding stroke (ischemic stroke) occurs due to blockage of the formation of fatty plaques in the walls of cerebral blood vessels that initially only narrow and causes the blood flow to the brain becomes slow but over time eventually clogged blood vessels in total. Blockages can also occur due to plaque formation in the blood vessels in the body are released and carried by the flow of blood to the brain.

Unlike the non-bleeding stroke, haemorrhagic stroke occurs due to rupture of blood vessels of the brain. Most often caused by high blood pressure, but may also by abnormal blood vessel itself.

Most of the actual stroke risk factors can be controlled. Among others, high blood pressure, heart disease, diabetes, smoking, obesity, high cholesterol, and excessive alcohol drinking.

Stroke risk factors in the two major components, namely: 
Risk factors that can not be changed

• Genetically, every person who has a family history of stroke, then he would have the potential to have a stroke
• People who had never had a stroke, had a risk of stroke again
• Age. There is a growing trend of men age will experience a decline in the condition of the cells throughout the body.

Risk factors that can be changed, meaning that it can be managed and improved, such as unhealthy lifestyle, lack of exercise, and others.
