TIA's can predict future stroke risk.

"We do have tools that allow us to determine the risk of future stroke after a transient ischaemic event. The most commonly used tool is the ABCD squared scale which estimates risk based on the patient’s age, blood pressure, clinical features, duration of symptoms and history of diabetes."

Mr Tanner’s risk of stroke is around 10% at 90 days, and 4% on day 2.

The best management strategy for these patients is still controversial. Often we are concerned that discharge may not be safe if the risk of recurrence is high.

Many centres have focused care for TIA patients on early assessment and intervention to try and reduce the risk of recurrence. For example, you may like to read the results of the EXPRESS study which was published in the Lancet in 2007. You will find the study in Volume 370 on page 1432. Peter Rothwell is the lead author."
