Migraine linked to poor headache outcomes in people with idiopathic intracranial hypertension

  • A database analysis evaluated whether the presence of migraine is associated with outcomes in 97 patients with idiopathic intracranial hypertension (IIH), of whom 77% experienced headache improvement and 28% freedom from headache during 1 year of follow-up.
  • Patients with IIH and differentiated migraine (IIH-MIG) had significantly lower rates of headache improvement than those with IIH and non-migraine headache (67 vs 89%), as well as significantly lower rates of freedom from headache (11 vs 33%).
  • After multivariable adjustment, IIH-MIG was associated with a significantly lower odds of achieving these favorable outcomes, with odds ratios (ORs) of 0.57 and 0.29, respectively, but a significantly lower risk for visual worsening (OR=0.26).
