Stroke risk is impt.: The major concern after a TIA is the risk of a stroke, for which a TIA is like a warning sign. Studies have shown that 10-15% of people will have a stroke within 3 months of a TIA and 50% will occur within 2 days. There is also a risk of cardiovascular events. Therefore risk factors for stroke (e.g. Hypertension, diabetes, high cholesterol, smoking, etc.) must be addressed immediately after a tia.

Fair chance: If you had one TIA the chances of another TIA or stroke is increased. It depends on comorbid conditions associated with it, like hypertension, high cholesterol, diabetes etc.

High: Chances maybe high if the risk factors for TIA are not under control. Those include elevated blood pressure, high cholesterol, smoking, lack of physical activity, unhealthy diet. Sometimes TIA is caused by blood clots. Chance of TIA recurring in this case is especially high.
