Demographic, clinical and comorbidity data in a large sample of 1147 patients with migraine in Mexico City

et al. 2005

The objective was to identify the sociodemographic and clinical characteristics of a large sample of patients with migraine in Mexico City. This cross–sectional study was performed in two tertiary centers in Mexico City and affiliated hospitals. We evaluated the presence of migraine through a standardised interview according to the criteria of the International Headache Society. We studied 1147 patients. The mean age was 37.1±13.6 (6–77) years. Nine hundred and twenty one patients were female (80%). The age of onset of migraine was 19.4±10.3 (1–69) years. Six hundred and four patients had migraine with aura (53%) and 543 without aura (47%). The female/male ratio was 4:1. One hundred and forty–seven patients had cardiovascular problems (13%), 72 had neurological problems (6%), 233 had gastrointestinal problems (20%) and 323 had psychiatric problems (28%). In this study we described the clinical characteristics of a large sample of patients with migraine in Mexico City. Our sample has similar characteristics to other countries.

“…The first, prior to the formulation of the IHS criteria [4], demonstrated it in 40% of 50 migraineurs studied [5]; the second, in a more recent study in a larger patient population, revealed the presence of osmophobia in 25% of migraineurs [6]. In a recent epidemiologic study of a Latin American patient population, osmophobia in migraineurs was said to be "almost always" present in 47.7% of subjects [7]. No study has ever been conducted that considered this phenomenon in relation to the different forms of primary headache.…”

Osmophobia in primary headaches

et al. 2005

This study evaluates osmophobia (defined as an unpleasant perception, during a headache attack, of odours that are non–aversive or even pleasurable outside the attacks) in connection with the diagnosis of primary headaches. We recruited 775 patients from our Headache Centre (566 females, 209 males; age 38±12 years), of whom 477 were migraineurs without aura (MO), 92 with aura (MA), 135 had episodic tension–type headache (ETTH), 44 episodic cluster headache (ECH), 2 chronic paroxysmal hemicrania (CPH) and 25 other primary headaches (OPHs: 12 primary stabbing headaches, 2 primary cough headaches, 3 primary exertional headaches, 2 primary headaches associated with sexual activity, 3 hypnic headaches, 2 primary thunderclap headaches and 1 hemicrania continua). Among them, 43% with MO (205/477), 39% with MA (36/92), and 7% with CH (3/44) reported osmophobia during the attacks; none of the 135 ETTH and 25 OPH patients suffered this symptom. We conclude that osmophobia is a very specific marker to discriminate adequately between migraine (MO and MA) and ETTH; moreover, from this limited series it seems to be a good discriminant also for OPHs, and for CH patients not sharing neurovegetative symptoms with migraine. Therefore, osmophobia should be considered a good candidate as a new criterion for the diagnosis of migraine.

“…Although the disability of migraine in the United States, France, and Latin America is similar, just 6% of the migraineurs in France and 2% in Latin America were current preventive users. 23,24 Our study has limitations. First, we used a validated questionnaire to diagnose migraine just in those with self-defined severe headaches.…”

Abstract-Objectives: 1) To reassess the prevalence of migraine in the United States; 2) to assess patterns of migraine treatment in the population; and 3) to contrast current patterns of preventive treatment use with recommendations for use from an expert headache panel. Methods: A validated self-administered headache questionnaire was mailed to 120,000 US households, representative of the US population. Migraineurs were identified according to the criteria of the second edition of the International Classification of Headache Disorders. Guidelines for preventive medication use were developed by a panel of headache experts. Criteria for consider or offer prevention were based on headache frequency and impairment. Results: We assessed 162,576 individuals aged 12 years or older. The 1-year period prevalence for migraine was 11.7% (17.1% in women and 5.6% in men). Prevalence peaked in middle life and was lower in adolescents and those older than age 60 years. Of all migraineurs, 31.3% had an attack frequency of three or more per month, and 53.7% reported severe impairment or the need for bed rest. In total, 25.7% met criteria for "offer prevention," and in an additional 13.1%, prevention should be considered. Just 13.0% reported current use of daily preventive migraine medication. Conclusions: Compared with previous studies, the epidemiologic profile of migraine has remained stable in the United States during the past 15 years. More than one in four migraineurs are candidates for preventive therapy, and a substantial proportion of those who might benefit from prevention do not receive it.
