There are two types, migraine without aura and migraine with aura. The diagnosis of migraine is essentially clinical. Worldwide prevalence was estimated at 11.6% in 2009. In Africa, it is estimated at 10.4%. Objective: To describe the clinical and therapeutic aspects of migraine in Brazzaville. Patients and Methods: This was a door-to-door cross-sectional study conducted from 1<sup>st</sup> May to 1<sup> st</sup> July 2018 in the city of Brazzaville. Subjects over 18 with clearly expressed consent were included. The questionnaire covered demographic characteristics, diagnostic criteria for migraine according to the IHS, treatments taken. The degree of disability was determined using the Migraine Disability Assessment Scale (MIDAS). Statistical analysis was performed using SPSS 22.0 for MAC. Results: Of the 1017 subjects interviewed in this study, 115 (39.9%) had migraine, including 73 women (63.47%) and 42 men (36.52%). In the group of migraine sufferers, the number of cases of definite migraine was 61 (53.04%) and that of probable migraine 54 (46.95%). For 81 migraine sufferers (70.43%), stress was the triggering factor. The frequency of attacks was weekly and monthly for 30 (26.1%) and 19 (16.5%) sufferers respectively. The location of the migraine was unilateral in 38% of cases and tilted in 24.3%. The intensity of the attack was described as moderate and severe in 41.7% and 57.4% of subjects respectively. Phonophobia/photophobia accompanied the migraine in 65.2% of cases. One hundred and eight subjects were treated. Of these, 106 (98.1%) were on medication. Eleven (10.37%) had received a medical prescription, and ninety-seven (89.8%) were self-medicating. Five and three subjects were under the care of a general practitioner and a neurologist respectively. Conclusion: Migraine is a frequent pathology in Brazzaville. Its preponderance among young people and women calls for the implementation of effective prevention strategies for these already vulnerable social groups. The form without aura was the most common type. Visual aura was the most common type. Headache-related symptoms were dominated by phonophotophobia, followed by nausea and vomiting. Almost all migraine sufferers were self-medicating, and very few were under the care of a doctor. First-line analgesics and NSAIDs were the mainstay of treatment.展开更多

Methods: We thoroughly searched Google Scholar, PUBMED, Scopus, and Web of Science databases using keywords related to migraines and lifestyle factors. Keywords incorporated the Boolean operator “and” to narrow search results. Following the PRISMA guidelines, we identified, screened, and evaluated studies for inclusion, resulting in nine studies meeting the eligibility criteria. Results: A total of 4917 records were initially identified from Scopus (2786), PubMed (854), and Web of Science (1277). Following deduplication, 3657 records underwent title screening, with 382 additionally screened by abstract. Ultimately, 88 full-text articles were assessed, resulting in 9 studies meeting eligibility for qualitative synthesis: 7 prospective and 2 retrospective studies. Our findings highlight the multifaceted role of lifestyle factors in migraine pathophysiology and management. Dietary habits, such as high-calorie, high-fat, and gluten-containing diets were linked to migraine triggers. Moderate physical activity showed beneficial effects on migraine management, while intense exercise could exacerbate symptoms. Poor sleep hygiene and insomnia were strongly associated with increased migraine frequency and severity. Chronic stress and poor mental health significantly contributed to migraine exacerbation, with stress management techniques proving beneficial. Environmental factors, including light, sound, weather changes, and allergens, were also identified as significant migraine triggers. Conclusions: Personalized lifestyle modifications, tailored to individual patient profiles, are crucial in managing migraines. Evidence-based recommendations include balanced diets, moderate physical activity, improved sleep hygiene, stress management techniques, and environmental adaptations.展开更多
