Stroke and its symptoms
A stroke occurs when a clot or disturbance occurs to the blood supply in the brain. In an acute ischaemic stroke, part of the brain is deprived of oxygen and becomes irreversibly damaged. Brain tissues surrounding the damaged part will also be affected, but can potentially be saved with quick action. If you suspect you are feeling the onset of a stroke, seek help immediately if one of the following symptoms occurs suddenly.
1. Weakness or numbness on one side of the body
2. Slurred speech or difficulty in speaking
3. Loss of vision or double vision
4. Unsteadiness in walking or uncoordinated movements
6. Excruciating headache
