Cerebro vascular Disease
It occurs in approximately 1.2 to 2.5 out of every 100,000 children each year. Stroke may occur at any age, but in childhood it most often occurs between the ages of 1 and 5.
It occurs when the blood supply to the brain is cut off. This could be because a blood vessel is blocked, called an ischemic stroke, or because a blood vessel bursts, called a hemorrhagic stroke. When the blood vessel bursts, it prevents normal blood flow to the brain and allows blood to leak into the brain, where it destroys tissue. The most common cause of stroke in children is congenital cyanotic heart disease and sickle cell disease. However, drugs, such as cocaine, can narrow the blood vessels and cause stroke.
The effects of stroke depend upon what part of the brain has been damaged. They may be slight or severe, temporary or permanent. People who have had a stroke may experience the following symptoms:
Weakness, numbness, or loss of function of face, arm, or leg especially on one side of the body,
- Memory loss,-
- Problems speaking or understanding speech,
- Loss of balance or coordination,
- Difficulty swallowing,
- Personality changes,
- Loss of bowel/bladder control,
- Sudden blurred or decreased vision in one or both eyes,
- Sudden severe headache.
The physician may order several tests to diagnose the cause of the stroke.
Tests can include an MRI or CAT scan, which are used to see the brain tissue, identify where the damage has occurred, and, possibly, identify the cause of the stroke. An ultrasound test (Doppler) can often identify blocked arteries that could be reducing blood flow to the brain.
