A transient ischemic attack (TIA) is a type of mini-stroke, and is caused by a temporary disruption in the blood supply to the brain. Often, the symptoms of a TIA are similar to those of a stroke, but they usually don’t last as long – typically, a TIA will last for less than 24 hours.
It is not possible to predict how many times a person may have a TIA. In some cases, a person may have a single TIA and never have another one, while in other cases, a person may have multiple TIA episodes over a period of time. In general, the risk of having multiple TIA episodes increases with age, and is higher in people who have certain medical conditions, such as high blood pressure, high cholesterol, diabetes, and heart disease.
It is important to take any signs of a TIA seriously, as it can be a warning sign of a future stroke. If you experience any of the symptoms of a TIA, it is important to seek medical attention immediately.
