A stroke is a ""brain attack"". It can happen to anyone at any time. It occurs when blood flow to an area of brain is cut off. When this happens, brain cells are deprived of oxygen and begin to die. When brain cells die during a stroke, abilities controlled by that area of the brain such as memory and muscle control are lost. The signs and symptoms are:
• Trouble with speaking and understanding.
• Paralysis or numbness of the face, arm or leg.
• Trouble with seeing in one or both eyes.
• Trouble with walking.
HOW IS STROKE DIAGNOSED?
Strokes are usually diagnosed by carrying out physical tests and studying images of the brain produced during a scan. For people with more complex symptoms, where the extent or location of the damage is unknown – and in people who have recovered from a transient ischaemic attack (TIA) – an MRI scan is more appropriate. This will provide greater detail of brain tissue, allowing smaller, or more unusually located areas affected by a stroke to be identified. A swallow test is essential for anybody who has had a stroke, as swallowing ability is commonly affected early after a stroke. A carotid ultrasound scan can help show if there is any narrowing or blockages in the neck arteries leading to your brain.
HOW IS STROKE TREATED?
The treatment for stroke depends on the kind of stroke one has. In Ischemic stroke, the symptoms include TPA via catheter. For hemorrhagic strokes medicines like Warfarin or Clopidogrel are given right to the brain via blood. There are also lot of other emergency procedures carried out and the patient should be immediately taken to the hospital.
