Strokes are often thought of as sudden medical emergencies, but in some cases, the body may provide warning signs before a major stroke occurs. One important warning is a transient ischemic attack (TIA), often called a “mini-stroke.” A TIA happens when blood flow to part of the brain is temporarily reduced, causing stroke-like symptoms that usually disappear within minutes or hours.
Although the symptoms resolve, a TIA is a medical emergency because it may signal an increased risk of a future stroke. Recognizing these warning signs and seeking immediate medical evaluation can help reduce that risk.
What Is a Transient Ischemic Attack (TIA)?
A transient ischemic attack occurs when blood flow to part of the brain is briefly interrupted. Unlike a stroke, the blockage clears quickly and symptoms resolve without permanent brain injury. However, a TIA should never be ignored, as it may indicate an increased likelihood of a stroke in the near future.
