A mini-stroke, also known as a transient ischemic attack (TIA), is caused by a temporary lack of blood flow to the brain. The symptoms may resemble those of a stroke, but they usually last only a few minutes.
A transient ischemic attack does not result in permanent damage, but it may be a sign you are at risk of a stroke. According to Mayo Clinic , around one-third of those who have a mini stroke eventually develop a stroke. Around half of these stroke incidences happen within a year of having a mini stroke.
If you are having a mini stroke, you may experience weakness, numbness, or paralysis on one side of your body. This usually affects the arms, face, or legs. Your speech may also sound slurred and you may feel displaced. Some people experience temporary blindness or other visual abnormalities.
You should see a doctor if you experience any of these symptoms. Your doctor will evaluate you to determine the cause of your TIA then recommend a treatment option for you. The treatment is meant to prevent future attacks and reduce your risk of stroke. This article discusses some of the treatments your doctor may recommend if you recently experienced a mini stroke.
You can reduce your risk of a future stroke or second TIA by making some of the following lifestyle changes :
- Eat healthy diets containing plenty of fiber and little salt and fat
- Exercise regularly
- Do not smoke or drink alcohol
