Link Between Aura Without Headache and Aura with Migraine Explored

Research Summary

A recent study published in the American Journal of Neuroradiology explores the clinical features of patients with typical aura without headache (TAWH) and their relation to cortical hyperperfusion (CHP) detected via arterial spin-labeling MRI. Researchers compared 65 TAWH cases and 98 cases of migraine with aura (MWA) with scintillating scotoma. Divided into four groups based on CHP presence, the study found that TAWH patients with CHP shared similar clinical traits with those having MWA. However, TAWH without CHP showed a higher incidence of men, older age, and conditions like hypertension. This absence of CHP suggests considering other diseases beyond migraines.
