Canadian investigators suggest that as many as 15% of patients who suffer transient ischemic attack (TIA) and minor strokes become disabled. Ongoing symptoms, diabetes, female gender, and CT/CT angiography-positive metric were predictive of disability after TIA and minor stroke. Just 12% of those who did not have a recurrent event were disabled, compared with 53% of those who did.
