A stroke is a serious, life-threatening medical condition that occurs when the blood supply to part of the brain is cut off. Symptoms of stroke are
• Sudden numbness or weakness of the face, arm or leg (especially on one side of the body)
• Sudden confusion, trouble speaking or understanding speech
• Sudden trouble seeing in one or both eyes
• Sudden trouble walking, dizziness, loss of balance or coordination
• Sudden severe headache with no known cause
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?
Stroke needs to be treated immediately for avoiding permanent damage to brain. Treatment aims at restoring blood supply to brain immediately. Mechanical clot removal is required to treat stroke.
