Headache is a common neurological disorder affecting 1 in 2 people in developed countries, with a reported incidence of 1,100 per 100,000 individuals. Patients with vertebral artery dissection (VAD) represent a small subset of this population. VAD is recognized as a rare but potentially fatal vascular condition, with an estimated incidence of 1 to 2 per 100,000 individuals. In Western countries, carotid artery dissection (CAD) is commonly observed, and its pathophysiology and therapeutic strategies have been extensively studied. In contrast, clinical observations in Japan suggest that VAD is overwhelmingly more prevalent in headache clinics, whereas CAD is infrequently diagnosed. VAD is typically reported in severe clinical presentations, including subarachnoid hemorrhage, intracerebral hemorrhage, and cerebral infarction. The clinical profile of VAD remains poorly defined, although a substantial number of patients may present with mild forms of the disease manifesting merely as a headache.
