A pre-stroke, often referred to as a transient ischemic attack (TIA), is a medical condition that acts as a warning sign for a potential stroke. It is sometimes called a "mini-stroke" because it shares similar symptoms with a stroke, but the effects are temporary and do not last as long. During a TIA, blood flow to a part of the brain is interrupted, but the blockage is not severe or long-lasting enough to cause permanent damage. The symptoms of a TIA are similar to those of a stroke and can include sudden weakness, numbness, difficulty speaking, or loss of vision, but they typically resolve within a few minutes to an hour. read more >>
