OBJECTIVES: The purpose of this study was to evaluate the course of headache in patients with moderate-to-severe headache due to aneurysmal subarachnoid hemorrhage (aSAH) and to identify its predisposing factors. BACKGROUND: Little is known about the long-term course of headache in patients with aSAH. METHODS: Since September 2009, patients with aSAH have had their headaches prospectively rated using a numeric rating scale (NRS). From this database containing 838 patients, 217 were included and all included patients met the following criteria: (1) presence of ruptured intracranial aneurysms on computed tomography angiography or magnetic resonance angiography; (2) alert consciousness (Glasgow Coma Scale 15); (3) newly onset moderate-to-severe headache (NRS ≥ 4) due to ruptured intracranial aneurysms; and (4) good clinical outcome at discharge (modified Rankin Scale 0, 1, or 2). We observed the changes in NRS scores from initial to 12-month follow-up and identified the predisposing factors of NRS changes. RESULTS: Of the 217 patients, 182 (83.9%) experienced improvement in NRS score ≤ 3 upon discharge. The NRS scores at discharge were significantly lower than those on admission (P < .001). The independent predisposing factors for headache improvement included previous stroke (odds ratio [OR] = 0.141; 95% CI 0.051-0.381; P < .001), previous headache treated with medication (OR = 0.079; 95% CI 0.010-0.518; P = .008), and endovascular treatment (EVT; OR = 2.531; 95% CI 1.141-5.912; P = .026). The NRS scores tended to decrease continuously until the 12-month follow-up. EVT and symptomatic vasospasm were independently associated with a decrease of NRS in the follow-up periods. CONCLUSIONS: The course of headache in patients with aSAH continuously improved during the 12 months of follow-up. Headache improvement might be expected in patients who were treated with EVT and in those who did not have previous stroke or headache.
