New migraine-like TNAs in older adults can be due to migraine aura or TIA. Clinical distinction can be difficult after a first attack, particularly in older patients with vascular risk factors. In the absence of previous prospective population-based studies, we determined the long-term risk of stroke in patients with new migraine-like TNAs, defined pragmatically as those in whom the assessing neurologist was unable to say confidently that the event was a definite aura or a definite TIA.
