In a case–control study published recently in Acta Neurologica Scandinavica, 38 of 51 (74.5%) patients with saccular intracranial aneurysm (SIA) and migraine reported remission or reduced frequency of migraine attacks during the year after surgery. Tension-type headaches (THHs) were not reduced. Unruptured SIA has been previously linked to an increased prevalence of migraine, but not THH. Whether interventions such as coiling or clipping of the aneurysm could alleviate migraine in patients with SIA has been unclear.
