Efficacy of Ginkgolide B in the prophylaxis of migraine with aura.

In a multicentric, open, preliminary trial, we evaluated the use of ginkgolide B, a herbal constituent extract from Ginkgo biloba tree leaves, in the prophylactic treatment of migraine with aura (MA). Fifty women suffering from migraine with typical aura, or migraine aura without headache, diagnosed according to International Headache Society criteria, entered a six-month study. They underwent a two month run-in period free of prophylactic drugs, followed by a four month treatment period (subdivided into two bimesters, TI and TII) with a combination of 60 mg ginkgo biloba terpenes phytosome, 11 mg coenzyme Q 10, and 8.7 mg vitamin B2 (Migrasoll), administered twice daily. A detailed diary reporting neurological symptoms, duration, and frequency of MA was compiled by patients throughout the trial. The number of MA significantly decreased during treatment (from 3.7 +/- 2.2 in the run-in period, to 2.0 +/- 1.9 during TI and to 1.2 +/- 1.6 during TII; Anova for repeated measures: P < 0.0001). There was also a statistically significant decrease in the average MA duration, which was 40.4 +/- 19.4 min during run-in, 28.2 +/- 19.9 during TI, and 17.6 +/- 20.6 during TII. Total disappearance of MA was observed in 11.1% patients during TI and in 42.2% of patients during T2. No serious adverse event was provoked by Migrasoll administration. Ginkgolide B is effective in reducing MA frequency and duration. The effect is clearly evident in the first bimester of treatment and is further enhanced during the second

Comparison of frovatriptan plus dexketoprofen (25 mg or 37.5 mg) with frovatriptan alone in the treatment of migraine attacks with or without aura: A randomized study

Background Drugs for migraine attacks include triptans and NSAIDs; their combination could provide greater symptom relief. Methods A total of 314 subjects with history of migraine, with or without aura, were randomized to frovatriptan 2.5 mg alone (Frova), frovatriptan 2.5 mg + dexketoprofen 25 mg (FroDex25) or frovatriptan 2.5 mg + dexketoprofen 37.5 mg (FroDex37.5) and treated at least one migraine attack. This was a multicenter, randomized, double-blind, parallel-group study. The primary end point was the proportion of pain free (PF) at two hours. Secondary end points were PF at one and four hours, pain relief (PR) at one, two, four hours, sustained PF (SPF) at 24 and 48 hours, recurrence at 48 hours, resolution of nausea, photophobia and phonophobia at two and four hours, the use of rescue medication and the judgment of the treatment. Results The results were assessed in the full analysis set (FAS) population, which included all subjects randomized and treated for whom at least one post-dose intensity of headache was recorded. The proportions of subjects PF at two hours (primary end point) were 29% (27/93) with Frova compared with 51% (48/95 FroDex25 and 46/91 FroDex37.5) with each combination therapies ( p < 0.05). Proportions of SPF at 24 hours were 24% (22/93) for Frova, 43% (41/95) for FroDex25 ( p < 0.001) and 42% (38/91) for FroDex37.5 ( p < 0.05). SPF at 48 hours was 23% (21/93) with Frova, 36% (34/95) with FroDex25 and 33% (30/91) with FroDex37.5 ( p = NS). Recurrence was similar for Frova (22%, 6/27), FroDex25 (29%, 14/48) and FroDex37.5 (28%, 13/46) ( p = NS), meaning a lack of improvement with the combination therapy. Statistical adjustment for multiple comparisons was not performed. No statistically significant differences were reported in the occurrence of total and drug-related adverse events. FroDex25 and FroDex37.5 showed a similar efficacy both for primary and secondary end points. There did not seem to be a dose response curve for the addition of dexketoprofen. Conclusion FroDex improved initial efficacy at two hours compared to Frova whilst maintaining efficacy at 48 hours in this study. Tolerability profiles were comparable. Intrinsic pharmacokinetic properties of the two single drugs contribute to this improved efficacy profile

Migraine and lifestyle in childhood

Migraine is one of the most frequently reported somatic complaints in childhood, with a negative impact on health-related quality of life. The incidence of migraine in childhood has substantially increased over the past 30 years, probably due to both increased awareness of the disease and lifestyle changes in this age group. Indeed, several conditions have been identified as risk factors for migraine in childhood. Amongst these, dysfunctional family situation, the regular consumption of alcohol, caffeine ingestion, low level of physical activity, physical or emotional abuse, bullying by peers, unfair treatment in school and insufficient leisure time seem to play a critical role. Nevertheless, there are only few studies about the association between migraine and lifestyle in childhood, due to previous observations specifically focused on "headache" in children. In this brief review, we will concentrate upon recent studies aimed to explore migraine and lifestyle risk factors in childhood

Neuropsychological correlates of theory of mind in chronic migraine

Objective: Theory of mind (ToM), the ability to understand other minds-that is, their beliefs, intentions (cognitive ToM), or emotions (affective ToM)-and its neuropsychological mechanisms in migraine have been poorly investigated. The aim of the study was to explore the deficit of cognitive and affective ToM and its possible associations with cognitive functioning in patients with chronic migraine (CM). Method: Forty participants with CM and 40 age-, education-, and sex-matched healthy controls (HC) underwent clinical assessment, cognitive (the ToM Pictures Sequencing Task and the Advanced Test of ToM) and affective ToM (the Reading the Mind in the Eyes Task and the Emotion Attribution Task) tasks, and a comprehensive neuropsychological battery. Results: Patients with CM significantly reported a lower performance on tasks assessing ToM compared to HC, with an impairment demonstrated for cognitive ToM. Moreover, patients with CM achieved significantly lower scores on tests assessing cognitive flexibility, planning, abstract reasoning, and long-term memory with respect to HC. ToM abilities were significantly related to migraine severity, executive, and memory functions in CM patients. Conclusions: The findings demonstrated that patients with CM present difficulties in inferring others' mental states, which would be related to clinical and cognitive functioning. The clinical importance of these findings, implications for clinical practice, and future research are discussed

Pain processing in patients with migraine: an event-related fMRI study during trigeminal nociceptive stimulation

We explored the functional pattern of the pain-processing network in patients with migraine, in the interictal periods, during trigeminal noxious stimulation. Contact heat evoked potential stimulation induced thermal pain and functional magnetic resonance imaging were used to measure whole-brain activation in 16 patients with episodic migraine without aura and 16 age- and gender-matched healthy controls in response to a severe (53°C) noxious, a moderate (51°C) noxious, and a control (41°C) stimulus applied to the maxillary skin. When comparing the fMRI activation over the entire brain, patients with migraine, with respect to healthy controls, showed a significantly greater activation in the perigenual part of anterior cingulate cortex at 51°C and less activation in the bilateral secondary somatosensory cortex at 53°C. A group-by-stimulus interaction analysis revealed a region in the pons showing a divergent response in patients and healthy controls. Correlation analyses demonstrated that the pons activation correlated with higher headache-related disability in patients. Our findings demonstrate increased antinociceptive activity in patients with migraine, which may represent a compensatory reorganization to modulate pain perception at the same intensity of healthy controls

Galcanezumab for the prevention of high frequency episodic and chronic migraine in real life in Italy: a multicenter prospective cohort study (the GARLIT study)

The clinical benefit of galcanezumab, demonstrated in randomized clinical trials (RCTs), remains to be quantified in real life. This study aimed at evaluating the effectiveness, safety and tolerability of galcanezumab in the prevention of high-frequency episodic migraine (HFEM) and chronic migraine (CM) in a real-life setting

Impact of multiple treatment cycles with anti-CGRP monoclonal antibodies on migraine course: focus on discontinuation periods. Insights from the multicenter, prospective, I-GRAINE study

Objectives While a single 12-month treatment cycle (TrC) with anti-CGRP mAbs is not disease-modifying for most patients, there is limited understanding of the effects of multiple TrCs on migraine course. We evaluated whether a second TrC might modify the migraine course by comparing the occurrence of migraine relapse after discontinuation of the second TrC to that following the cessation of the first TrC. Methods In a real-life, multicenter, prospective study we considered all consecutive patients diagnosed with high-frequency episodic migraine (HFEM) or chronic migraine (CM) with &gt; 3 treatment failures and treated with any anti-CGRP mAbs for &gt;= 2 consecutive 12-month TrCs who were responders at week 12. The primary endpoint was the change in monthly migraine days (MMD) for HFEM or monthly headache days (MHD) for CM at the first month of treatment discontinuation after the second TrC (D2) compared to the first TrC (D1). Secondary endpoints included variations in monthly analgesic medications (MAM), Numeric Rating Scale (NRS), and Headache Impact Test (HIT-6) scores, &gt;= 50%, &gt;= 75%, and 100% response rates, and relapse from episodic migraine to CM and from no-medication overuse (MO) to MO at D2 vs. D1. Results One-hundred-seventy-eight patients completed two 12-month TrCs with anti-CGRP mAbs. At D2, patients experienced a significant reduction in MMD (- 0.6, p = 0.028), MHD (- 2.6, p &lt; 0.001), monthly analgesic medications (- 2.0, p &lt; 0.001), and HIT-6 score (- 2.2, p &lt; 0.001) compared to D1, indicating improved effectiveness. The &gt;= 50% response rate at weeks 45-48 during the first TrC was 95.5%, while at weeks 45-48 of the second TrC was 99.4%. Corresponding rates at D1 was 20.2% whereas at D2 was 51.6% (p &lt; 0.0001). No statistical difference emerged in &gt;= 75% and 100% responders. The relapse rate from episodic migraine to CM at D2 was lower than at D1 (12.3% vs 30.4%; p = 0.0002) Fewer patients experienced relapse from no-MO to MO at D2 compared to D1 (29.5% vs 68.7%; p = 0.00001). Discussion A second TrC with anti-CGRP mAbs demonstrated clinical improvements compared to the first one, as indicated by a milder migraine relapse at D2 compared to D1. Multiple TrCs with anti-CGRP mAbs could progressively modify migraine evolution by reducing CGRP-dependent neuroinflammatory nociceptive inputs to the brain
