Transient Ischemic Attack (TIA)

A transient ischemic attack (TIA) is a sudden and temporary disruption in blood flow to the brain that usually does not cause permanent damage. The symptoms of a TIA are similar to those of a stroke, but are short-lived and disappear completely within minutes to hours.

​

The causes of a TIA can be varied and include blockage or narrowing of blood vessels in the brain, blood clots traveling to the brain, and reduced blood flow in the brain due to factors such as high blood pressure, diabetes mellitus, or other health problems.

​

Symptoms of a TIA can come on suddenly and include weakness or numbness on one side of the body, loss of balance or coordination, difficulty speaking or confusion, blurred vision in one or both eyes, and headache.

​

Diagnosing a TIA begins with a physical exam and neurological tests performed by a doctor. Imaging tests such as a CT or MRI scan can also be used to determine the extent of the circulatory disorder in the brain.

​

Treatment for a TIA depends on the causes and may include medications to prevent blood clots and improve circulation, lifestyle changes such as exercise, eating healthily and avoiding risk factors, and surgical procedures to correct blood vessel problems.

​

It's important to note that a TIA can be an important warning sign of a coming stroke. Therefore, it is important to seek medical help quickly when TIA symptoms occur. Early diagnosis and treatment can help reduce the risk of future stroke and ensure a good prognosis.
