Non-aura visual disturbance tied with higher risk for chronic migraine than typical aura

Key clinical point: Patients with migraine without aura who experienced transient visual disturbance (MwTVD) had worse headache, higher migraine-related disability, more psychiatric comorbidities, and a higher risk for chronic migraine than those with migraine with visual aura (MA).

Major finding: MwTVD vs MA group had a higher prevalence of chronic migraine (41.9% vs 11.8%; P < .001) and higher mean Migraine Disability Assessment, anxiety, and depression scores (all P < .001), with transient visual disturbance being a significant risk factor for chronic migraine even after adjusting for confounding factors (adjusted odds ratio 4.75; P < .001).

Study details: This was a post hoc analysis of previously collected data of 2551 patients with migraine, of which 743 had MA and 1808 had MwTVD.
