Purpose of review To discuss the consequences of recent clinical data on migraine with aura for clinical practice and future research in the light of new diagnostic criteria for migraine with aura. Recent findings Migraine with aura is now distinguished from hemiplegic migraine and from basilar migraine. Migraine with typical aura has an aura consisting of visual, sensory, or speech symptoms. The aura symptoms typically develop gradually over 5 or more minutes, last between 5 and 60 minutes and, when more than one symptom is present, they occur in succession. Half-sidedness is typical of visual and sensory symptoms, whereas speech symptoms are typically aphasic, primarily of the Broca type. A visual aura rating scale with a high sensitivity and specificity has been developed to standardize the diagnosis of visual aura. The new classification, the new criteria, and the new knowledge about clinical features of migraine with aura are important both for routine clinical diagnosis and for future research studies. Summary Recent studies of the clinical features of migraine with aura allow a more precise diagnosis and classification than previously possible. A clear distinction between migraine with typical aura, hemiplegic migraine, and basilar migraine is important for genetic and other research studies.
