Strokes are a medical emergency and urgent treatment is essential.  Treatment depends on the type of stroke you have, including which part of the brain was affected and what caused it. Strokes are usually treated with medication. This includes medicines to prevent and dissolve blood clots, reduce blood pressure and reduce cholesterol levels. In some cases, procedures may be required to remove blood clots. Surgery may also be required to treat brain swelling and reduce the risk of further bleeding if this was the cause of your stroke. People who survive a stroke are often left with long-term problems caused by injury to their brain. Some people need a long period of rehabilitation before they can recover their former independence, while many never fully recover and need ongoing support after their stroke.
