Core Viewpoint - A diabetes drug, Liraglutide, has shown promise in reducing the frequency of debilitating migraines, potentially paving the way for a new treatment approach that targets intracranial pressure rather than just symptom management [3][4][7][20]. Group 1: Study Overview - The study involved 31 obese adults with high-frequency or chronic migraines who had not responded to at least two preventive treatments [10]. - Participants received daily subcutaneous injections of Liraglutide, starting at 0.6 mg and increasing to 1.2 mg over 12 weeks, while continuing existing migraine treatments [12]. - The study was conducted in Naples, Italy, from January to July 2024 [10]. Group 2: Results - After 12 weeks, the average number of headache days per month decreased significantly from 19.8 days to 10.7 days, a reduction of 9.1 days [15]. - Nearly half (48%) of participants experienced at least a 50% reduction in headache frequency, and 23% had a reduction of 75% or more [16]. - The MIDAS score, which measures migraine-related disability, dropped from 60.4 to 28.6, indicating significant improvement in daily functioning [17]. - The participants' BMI showed a slight decrease from 34.0 to 33.9, confirming that the reduction in headache frequency was not related to weight loss [18]. Group 3: Mechanism and Implications - The study suggests that Liraglutide may lower migraine frequency and severity by regulating intracranial pressure and modulating CGRP levels, rather than merely causing weight loss [19][23]. - This research represents a novel treatment strategy, differing from current migraine prevention drugs that focus on blocking CGRP action rather than preventing its release [20]. Group 4: Limitations and Future Research - The study has limitations, including its open-label design, small sample size, lack of a control group, and relatively short follow-up period, indicating the need for further research to validate these findings [21]. - Experts emphasize the necessity for more rigorous clinical trials before Liraglutide can be widely recommended for migraine treatment [26][28].
