Duration and characteristics of persistent headache following aneurysmal subarachnoid hemorrhage
Duration and characteristics of persistent headache following aneurysmal subarachnoid hemorrhage
Objective: to assess the long-term frequency, prognosis, and phenotype of persistent headache following aneurysmal subarachnoid hemorrhage (aSAH).
Background: very little is known about long-term headache following aSAH with no studies looking beyond 3 years.
Methods: retrospective analysis comparing aSAH cases to matched controls in the UK Biobank, a prospective cohort study. Headache frequency and phenotype were compared using group comparison tests. The relationship between headache fre-quency and time was assessed using correlation analysis.
Results: headache was more frequent following aSAH (aSAH: 258/864 [29.9%] vs. controls: 666/3456 [19.3%], χ2= 45.5, p< 0.001) at a median follow-up of 7.5 years. Headache frequency decreased over time (RS= −0.71, p= 0.028), affecting 29/58 (50%) patients in the first year and reducing to 13/47 (28%) patients 10 years later. Headache frequency was not related to aSAH severity (z= 0.249, p= 0.803), treat-ment (z= 0.583, p= 0.560), or hydrocephalus (z= −1.244, p= 0.214). There was a consistently higher frequency of migrainous features following aSAH compared to controls, although this did not reach statistical significance.
Conclusions: persistent headache is more frequent following aSAH compared to con-trols in the long term and the prevalence reduces gradually over time. The increased frequency of migrainous features suggests that selected patients with post-aSAH headache may benefit from migraine treatment.

Abstract
Objective: to assess the long-term frequency, prognosis, and phenotype of persistent headache following aneurysmal subarachnoid hemorrhage (aSAH).
Background: very little is known about long-term headache following aSAH with no studies looking beyond 3 years.
Methods: retrospective analysis comparing aSAH cases to matched controls in the UK Biobank, a prospective cohort study. Headache frequency and phenotype were compared using group comparison tests. The relationship between headache fre-quency and time was assessed using correlation analysis.
Results: headache was more frequent following aSAH (aSAH: 258/864 [29.9%] vs. controls: 666/3456 [19.3%], χ2= 45.5, p< 0.001) at a median follow-up of 7.5 years. Headache frequency decreased over time (RS= −0.71, p= 0.028), affecting 29/58 (50%) patients in the first year and reducing to 13/47 (28%) patients 10 years later. Headache frequency was not related to aSAH severity (z= 0.249, p= 0.803), treat-ment (z= 0.583, p= 0.560), or hydrocephalus (z= −1.244, p= 0.214). There was a consistently higher frequency of migrainous features following aSAH compared to controls, although this did not reach statistical significance.
Conclusions: persistent headache is more frequent following aSAH compared to con-trols in the long term and the prevalence reduces gradually over time. The increased frequency of migrainous features suggests that selected patients with post-aSAH headache may benefit from migraine treatment.
