A mini-stroke, medically called a transient ischemic attack (TIA), is a brief interruption of blood flow to part of the brain. Symptoms often appear suddenly—such as weakness on one side of the body, facial drooping, slurred speech, blurred vision, dizziness, or confusion—and may disappear within minutes. Because they resolve quickly, some people dismiss them as stress or fatigue. However, a TIA is a serious warning sign that requires immediate medical attention.
Risk factors include high blood pressure, diabetes, high cholesterol, heart rhythm problems, smoking, and physical inactivity. Older adults are particularly vulnerable. Although symptoms fade, the risk of a full stroke increases significantly in the hours or days following a TIA.
If a mini-stroke is suspected, seek emergency care right away. Doctors may perform imaging tests and prescribe medications to reduce clot risk. Healthy lifestyle changes—regular exercise, balanced nutrition, and blood pressure control—also play a crucial role in preventing future strokes and protecting long-term brain health.
