The ABCD system uses clinical features identifiable in primary or emergency care to reliably predict the risk of stroke in the acute phase following a transient ischemic attack. Further study is required to establish both the effectiveness of a refined system that includes carotid and brain imaging, and how such a refined system should be implemented in clinical practice.
