Transient Ischemic Attack (TIA)

What is a TIA?

Transient ischemic attacks (TIAs) are temporary deficits in neurologic function caused by a brief interruption of blood flow to part of the brain. Although the symptoms — such as weakness or numbness on one side of the body and difficulty speaking — are short-lived, TIAs are also possible warning signs of a full-blown stroke. Research conducted at Boston Children’s Hospital indicates that about 10 percent of children who experience a TIA will ultimately have a stroke.

What are the symptoms of a TIA?

Transient ischemic attacks (TIAs) produce sudden symptoms similar to those of strokes, such as:

  • Weakness or numbness on one side of the body
  • Difficulty speaking or understanding speech
  • Vision problems
  • Confusion
  • Sensation that the room is spinning (vertigo)

Symptoms of TIAs last less than 24 hours — often only for a few minutes and resolve. Children can experience multiple TIAs, which can be warning signs that a full-blown stroke may occur.

What causes a TIA?

TIAs occur when blood flow to a portion or region of the brain is interrupted, typically by a blood clot. Certain conditions are associated with an increased risk of having a TIA, including:
