The condition in five sentences. Migraine is a recurrent neurological disorder diagnosed from attack phenotype: ICHD-3 distinguishes migraine with and without aura and defines chronic migraine as at least 15 headache days per month, including at least 8 migraine-feature days (IHS 2018, PMID 29368949). It affects about 1.2 billion people in GBD 2023 and concentrates disability in adolescence through midlife, particularly among women, while mortality-based measures largely miss its impact (GBD 2023 Collaborators 2025, PMID 41240916). Trigeminal sensory signaling and CGRP are validated therapeutic biology, cortical spreading depolarization is the leading aura substrate, and polygenic neuronal and vascular signals coexist without a clinical biomarker (Ashina 2021, PMID 33773610; Fraser 2019, PMID 31847045; Hautakangas 2022, PMID 35115687). Evidence-rich NSAIDs and triptans remain acute anchors, while conventional preventives, onabotulinumtoxinA, CGRP antibodies and preventive gepants reduce attacks with bounded mean effects and substantial individual variation (Karlsson 2024, PMID 39293828; Dodick 2010, PMID 20487038; Lampl 2023, PMID 37208596). The practical frontier is comparative sequencing, prevention of chronification, non-stigmatizing medication-overuse care, reproductive safety, patient-weighted outcomes and evidence that crosses from association or mechanism to clinical selection.

Reading paths¶
- Clinical path — overview → classification and diagnosis → acute treatment → preventive treatment → guidelines → red flags and safety
- Mechanism path — trigeminovascular biology and CGRP → aura and cortical spreading depolarization → biomarkers
- High-frequency path — chronic migraine and chronification → medication-overuse headache → neuromodulation and behavioral care
- Life-course path — epidemiology and burden → children and adolescents → sex hormones, pregnancy and lactation → comorbidity and vascular risk
- Frontier path — OPEN-QUESTIONS → clinical-trials landscape → biomarkers → statistics sheet
- Human path — patient experience and advocacy → patient-voice themes → epidemiology and burden

Evidence and curation state¶
The full build was completed on 2026-08-28 and the separate audit passed on 2026-08-30. All 18 pages are status: curated: 388 retained unique PMIDs were re-fetched through live PubMed E-utilities, 40 NCT records through ClinicalTrials.gov API v2, quantitative and attribution errors were corrected, dated absence searches were refreshed, and the guideline registry was brought through 2026. Exact checks and remaining non-substantive access limitations are recorded in LOG.md. No frontend or publication files were changed.
