Stroke risk after transient ischemic attack in a Norwegian prospective cohort.

Background

Transient ischemic attack (TIA) is a risk factor of stroke. Modern treatment regimens and changing risk factors in the population justify new estimates of stroke risk after TIA, and evaluation of the recommended ABCD² stroke risk score.

Methods
