A "mini-stroke" is a term that refers to a transient ischemic attack (TIA), which is a temporary disruption in blood flow to the brain that results in stroke-like symptoms. Other synonyms for mini-stroke include "transient ischemic attack", "warning stroke", "minor stroke", "lacunar stroke", and "ischemic stroke". A TIA is a serious medical condition that requires prompt attention as it may lead to a full-blown stroke if left untreated. Common symptoms of a mini-stroke include weakness or numbness on one side of the body, slurred speech, confusion, dizziness or loss of balance, and sudden vision changes. If you experience any of these symptoms, seek medical help immediately.
