What is a Mini Stroke?

A mini stroke is also known as a transient ischemic attack (TIA) and occurs when a part of the brain experiences a temporary decrease in blood flow. This lack of blood flow impacts a person’s ability to perform basic tasks and can cause temporary neurological detrimental effects. While mini strokes are often thought of as a “warning sign” for more serious strokes, they can be just as serious and should be taken seriously. In fact, 10% of people who have mini strokes will have a full stroke within 90 days after the TIA.

What are the Symptoms of a Mini Stroke?

The symptoms of a mini stroke may include heaviness in the face, arm and/or leg, slurred speech, visual disturbances, loss of consciousness, confusion, coordination issues, memory loss, paralysis, numbness and tingling. These symptoms can develop suddenly, or they could come on quickly and then diminish slowly over a few minutes. If you believe you or someone you know is having a mini stroke, seek medical attention immediately to prevent further damage.

Treating and Preventing Mini Strokes

Mini strokes are commonly treated with both medications and lifestyle changes. Common medications prescribed for mini strokes may include antithrombotics and antiplatelet agents which help thin the blood and improve blood flow to the brain. Other medications may include anticoagulants and cholesterol-lowering medications.

In addition to medications, lifestyle changes such as a healthy diet, regular exercise and quitting smoking can be a great help in both treating and preventing mini strokes. Doctors may also suggest lifestyle changes such as managing stress, limiting salt and alcohol, and maintaining a healthy weight.

Mini strokes should be taken seriously. While they don’t cause lasting damage, they may be a warning sign of a greater risk of stroke and should be addressed immediately. With proper diagnosis and treatment, mini strokes can be treated and prevented.
