Conditions » Stroke
A stroke occurs when there is an interruption or reduction of blood supply to the brain which cause the brain tissue to be deprived of oxygen and nutrients. Due to this, brain cells begin to die. This is a medical emergency and prompt treatment is crucial with early action minimizing brain damage and complications. The symptoms of a stroke include:
- Trouble speaking and understanding. You may experience confusion, slur your words or find it difficult to understand what is being said.
- Paralysis or numbness in the face and limbs. Sudden weakness, numbness or paralysis in your face, arm or leg can be a warning side. These symptoms often only affect one side of your body.
- Trouble with seeing in one or both eyes. You may experience sudden blurred or blackened vision in one or either eyes, or you may see double.
- A sudden, severe headache, which may be accompanied by vomiting, dizziness or altered consciousness, may indicate you’re having a stroke.
- Trouble with walking and balance. You may stumble or experience sudden dizziness, loss of balance or loss of coordination.
There are multiple different types of strokes but most of them occur due to blood clots in the arteries that supply blood to the brain or hemorrhage. Causes of these usually include hypertension, blood thinners, high cholesterol or aneurysms which are weak spots in your blood vessel walls.
