Stroke

Stroke. What does it mean? Blood flow blockage or brain attacks? Stroke is usually defined as two types:

• Ischemic (caused by a blockage in an artery )
• Hemorrhagic (caused by a tear in the wall of the artery that produces bleeding in the brain )

A disruption in blood flow to the brain is the primary cause of a stroke. It can be disastrous and cause brain damage or even death. Our brain receives about 25% of the body's oxygen but it cannot store it. Brain cells require a constant supply of oxygen to stay healthy and function properly. Therefore, within minutes of a stroke, oxygen is cut off in the brain leading to death of brain cells . This also leads to some parts of the brain losing control over the activity of some parts of the body, resulting in temporary or permanent disability or paralysis.


The following complications could arise and may need continued medical cares :

• Urinary incontinence and urinary infection
• Cramp

Falls, usually to the affected side
Reduced blood supply to the brain may result in confusion and speech disturbances.
