A Stroke is what happens when blood flow to part of the brain is interrupted. As a result, oxygen deprivation to brain tissue occurs and, which, in turn, can lead to devastating consequences. The severity of symptoms depends on the location of the Stroke and the size of the Stroke. Some of the symptoms consist of neck stiffness, severe headache, loss of vision, dizziness and loss of balance, among others.
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?
Emergency treatment for stroke depends on whether you're having an ischemic stroke blocking an artery — the most common kind — or a hemorrhagic stroke that involves bleeding into the brain. To treat an ischemic stroke, doctors must quickly restore blood flow to your brain. Other medications are used to treat the symptoms and in worse cases various surgical procedures are done depending on the type of stroke.
DID YOU KNOW?
During the recovery process after a Stroke, a person may need ongoing rehabilitation. A massive Stroke can be fatal.
