Transient Ischemic Attack (TIA)

Often referred to as a "mini-stroke, a Transient Ischaemic Attack (TIA) is a brief episode of neurological impairment brought on by a momentary blood supply disturbance to a portion of the brain. Unlike a full-fledged stroke, a TIA usually resolves in minutes to several hours, typically under 24 hours, and does not cause permanent brain damage.

Although a TIA's symptoms go away rapidly, it is a medical emergency. Usually within days or weeks, a TIA acts as a warning sign that a more severe stroke could strike soon. Among the risk factors are diabetes, high blood pressure, smoking, high cholesterol, and past heart disease.
Essential are early diagnosis and action. Imaging studies like MRI or CT scans may be part of medical evaluation; treatment usually consists of lifestyle adjustments, blood thinners, and control of underlying diseases. TIAs present a vital window of opportunity to stop debilitating strokes. If you or someone else has TIA symptoms, get seen right away—even if the symptoms go away rapidly.
