A transient ischemic attack, or TIA is a mini stroke with stroke symptoms that usually lasts less than one hour. 

While TIAs generally do not cause permanent brain damage, they are a serious warning sign of a stroke and should not be ignored. In fact, the risk for stroke is especially high in the first few days after a TIA. When a blood vessel in the brain becomes blocked, diminishing the blood flow for a short period of time, this can lead to temporary symptoms such as slurred speech or blurry vision. 

TIAs are usually caused by one of three things: low blood flow from a major artery to the brain, a blood clot in the body that breaks off, travels to the brain and blocks a blood vessel, or plaque buildup of a smaller blood vessel deep in the brain. 

Risk factors for TIA include:

• Family history of stroke or TIA
• People 55 years or older, predominantly men
• Being overweight
• High blood pressure
• Diabetes
• Smoking tobacco
• High cholesterol
• Race/Ethnicity: African Americans have the highest rate of of TIA 

If you are diagnosed with TIA, you will be encouraged to make lifestyle changes to reduce your risk of further symptoms. Changes include quitting smoking, exercising more, and eating healthier foods.Ask your healthcare professional about the best stroke prevention options for you.
