Symptoms, Causes, and Consequences Stroke

Sunday, August 28, 2011

Cerebrovascular diseases including stroke (brain blood vessel) which is marked by the death of brain tissue (cerebral infarction) which occurred due to reduced blood flow and oxygen to the brain. Decreased blood flow and oxygen could be due to blockage, constriction or rupture of blood vessels.

WHO defines that stroke is a function of the symptoms of nervous system deficits caused by cerebrovascular disease and not by others from it.

Stroke was divided into two types: Hemorrhagic stroke and ischemic stroke. 

Ischemic stroke is blockage of blood vessels that cause blood flow to the brain in part or whole stop. 80% of strokes are ischemic strokes. Ischemic stroke is divided into three types, namely: 

1. Thrombotic stroke: thrombus formation process that make clotting. 
2. Embolic stroke: the closing of an artery by a blood clot. 
3. Systemic Hipoperfusion: Decreased blood flow to all parts of the body due to an interruption of heart beats.

Hemorrhagic stroke is a stroke caused by rupture of blood vessels of the brain. Nearly 70% of cases of hemorrhagic strokes occur in people with hypertension.

Hemorrhagic stroke there are two types, namely:

1. Intracerebral haemorrhagic: bleeding that occurs in brain tissue. 
2. Subarachnoid haemorrhagic: bleeding that occurs in the subarachnoid space (a narrow space between the brain surface and the layer of tissue covering the brain).

Signs and Symptoms of Stroke

Based on its location in the body, symptoms of stroke is divided into the following:

1. Parts of the central nervous system: muscle weakness (hemiplegia), stiffness, decreased sensory function 
2. Brain stem, where there are 12 cranial nerves: decreased ability to smell, taste, hear, and view the partial or total, decreased reflexes, impaired facial expression, impaired breathing and heart rate, weak tongue.
3. Cerebral cortex: aphasia, apraxia, memory decline, hemineglect, confusion.

If signs and symptoms disappear within 24 hours, expressed as a transient ischemic attack (TIA), which is a small attack or initial stroke attack.

Stroke Causes
Medical risk factors, including hypertension (high blood pressure), cholesterol, atherosclerosis (hardening of the arteries), heart disorders, diabetes, family history of stroke, migraine.

Behavioral risk factors, including smoking (active & passive), unhealthy foods (junk food, fast food), Alcohol, Lack of exercise, Snoring, Oral Contraception, Drugs, Obesity.

80% of the trigger stroke is hypertension and arteriosclerosis, according to statistics. 93% of people with diseases of thrombosis related to high blood pressure disease.

The trigger stroke is basically, an uncomfortable mood (angry), drinking too much alcohol, smoking and happy eating fatty foods.

Agony Post-Stroke

Already Falling Stairs hit Pula, saying that's right for people with Stroke.

After a stroke, brain cells die and the hematoma formed who will be reabsorbed gradually. This natural process is completed within 3 months. At that time, 1 / 3 of the survivors become dependent and may develop complications that can lead to death or disability

It is estimated there are 500,000 people affected by stroke. Of these:

• 1 / 3 -> can be restored,
• 1 / 3 -> experiencing mild to moderate functional impairment,
• 1 / 3 remaining -> suffered severe functional impairment that requires ongoing patient on the mattress.

Only 10-15% of stroke survivors can return to normal life as usual, the rest have disabilities, so that many stroke patients suffering from stress caused due to disability after a stroke attack.

Stroke due to Other:

• 80% reduction in partial / total arm and leg movements.
• 80-90% have trouble thinking and remembering.
• 70% suffer from depression.
• 30% had difficulty speaking, swallowing, distinguish right and left.

Stroke is no longer just attacking the elderly, yet now tends to strike younger generation who are still productive. Stroke is also no longer belong to citizens of the affluent city, but also experienced by rural residents who live with all the limitations.

This will impact on the declining levels of productivity and can lead to disruption of socio-economic families. In addition to its high cost of post-stroke treatment, which also suffered a stroke is the backbone of the family who usually perform less healthy lifestyles, caused by a solid rushing.
