Transient Ischemic Attack

Transient Ischemic Attack (TIA)

A transient ischemic attack (TIA) is also called a mini stroke. It is a neurological event that causes temporary warning signs and symptoms of a stroke. This event typically lasts less than one hour. A TIA shares many of the same signs and symptoms of a stroke and is sometimes referred to as a mini stroke.

TIA is caused by a temporary reduction or block in the blood supply to the brain, just like a stroke. TIAs, however, usually last for a few minutes and then subside completely, unlike a stroke that usually produces lasting damage.

TIA can also cause a temporary loss of some physical and mental functions. Additionally, TIAs can cause speech, vision, and balance problems, as well as weakness or numbness in the limbs.

It is important to recognize the warning signs of a TIA, as it can be a precursor to a stroke. Some common warning signs of a TIA include:

  • Numbness or weakness in the face, arms, or legs, particularly on one side of the body
  • Confusion or trouble understanding others
  • Difficulty speaking
  • Trouble seeing in one or both eyes
  • Difficulty walking, dizziness, or loss of balance or coordination
  • Severe headache with no known cause

It is important to seek medical attention immediately if you experience any of these signs, as prompt recognition and treatment can reduce the risk of a major stroke in the future.

Though TIA does not often cause lasting damages, it is not something that should be taken lightly. With prompt diagnosis and treatment, most people can recover and reduce their risk for a stroke.
