Chronic Migraine Epidemiology and Outcomes assessed for Comorbid pain and migraine chronicity

A migraine is a painful neurovascular disorder with an estimated prevalence of ≈15%. Current diagnostic criteria divide a headache into episodic (EM; <15 headache-days per month) and chronic (CM; ≥15 headache-days per month for >3 months among migraine characteristic. A migraine is comorbid among a large number of pain disorders.

Recognise the patterns of noncephalic pain comorbidity in people with episodic migraine (EM; <15 headache-days per month) including a chronic migraine (CM; ≥15 headache-days per month) and to analyse whether noncephalic pain could be an indicator for the 3-month onset or persistence of CM. From the Chronic Migraine Epidemiology and Outcomes (CaMEO) Study, which was a prospective, web-based study with cross-sectional modules embedded in a longitudinal design, the data were evaluated, at baseline and the 3-month follow-up. Relationships were studied between the number of noncephalic pain sites and the 3-month onset of CM or persistent CM.

Of 8,908 desirable respondents, 8,139 (91.4%) had EM and 769 (8.6%) had CM at baseline. At three months, the incidence of CM among those with baseline EM was 3.4%. When regulated for demographics and headache-day frequency, the odds of CM onset among those with baseline EM grow by 30% (95% confidence interval [CI] 1.21–1.40, p < 0.001) for each auxiliary on cephalic pain site at baseline. Amid those with CM at baseline, 50.1% had persistent CM at the 3-month follow-up. After reconciliation for demographics, each with CM was 15% (95% CI 1.07–1.25, p < 0.001) more probable to have persistent CM for individual auxiliary noncephalic pain site at baseline.

The assessment recommended that noncephalic pain may be a marker for headache chronicity that could be utilised to identify people with EM at risk of the onset of CM and people with CM at risk of persistent CM.
