Patients are often evaluated using the ABCD assessment tool to determine their risk of having a stroke in the days and weeks after the TIA. Which factor is INCORRECT?

Age greater than or equal to 60 (stroke risk increases with age)

Blood pressure (BP) greater than or equal to 120/80 mm Hg (either systolic or diastolic or both)

Clinical TIA features (unilateral [one-sided] weakness increases stroke risk)

Duration of symptoms (the longer the TIA symptoms last, the greater the risk of stroke)
