A mini-stroke, medically known as a Transient Ischemic Attack (TIA), occurs when blood flow to part of the brain is temporarily interrupted.
Unlike a major stroke, symptoms usually resolve within minutes or hours and do not cause permanent brain damage. However, a TIA should never be ignored.
A TIA is often considered a medical warning sign because it may indicate a significantly increased risk of a future stroke.
Why TIAs Matter
Many people mistakenly believe that because symptoms disappear, the problem has resolved.
In reality, a TIA can be an early warning that a major stroke could occur in the coming days, weeks, or months.
Seeking immediate medical attention can help identify the cause and reduce future risk.
1. Sudden Weakness or Numbness
One of the most common signs of a TIA is sudden weakness or loss of sensation.

Possible Signs
