What is TIA?

Transient Ischemic Attack (TIA) is often called a “mini stroke” or “warning stroke”. Like a stroke, TIA is caused by a blood clot. The difference is that with TIA the stoppage of blood flow is only temporary.

Most TIA symptoms occur very quickly and only last a short period of time. The average symptom lasts a minute and unlike a stroke, there is no permanent brain damage after a TIA.

Warning Signs of TIA

The warning signs of TIA are exactly the same as for a stroke. This includes sudden:

  • Numbness or weakness of the face, arm or leg – especially on one side of the body
  • Confusion, trouble speaking or understanding
  • Trouble seeing in one or both eyes
  • Trouble walking, dizziness, loss of balance or coordination
  • Severe headache with no known cause

While most strokes are not preceded by TIA, almost one-third of people who experience TIA have a stroke within a year. This is why TIA is called a “warning stroke”. By recognizing TIA symptoms and seeking medical treatment, you can identify what caused the TIA and prevent a stroke from occurring.
