What causes a TIA
In common with a full-blooded stroke, a TIA is normally caused by a blood clot that blocks the vessels supplying the brain with oxygen.
Some risk factors can increase your risk of a TIA such as smoking, high blood pressure, obesity, high cholesterol levels, and regularly drinking large quantities of alcohol.
Furthermore, having an irregular heartbeat can also increase your risk, as can diabetes.
A TIA is treated slightly differently to a stroke, however, there’s an important reason for this.
