8 Warning Signs of Stroke You Should Never Ignore — Plus 9 Ways to Help Prevent It
A stroke can happen suddenly, but some people experience warning signs beforehand, especially a transient ischemic attack (TIA), sometimes called a “mini-stroke.” A TIA occurs when blood flow to part of the brain is briefly reduced and can be an important warning that a full stroke may occur.
There is no guaranteed set of symptoms that appears exactly one month before a stroke, and many strokes happen without advance warning. However, recognizing possible warning signs can help you seek care quickly.
