Background: Headache disorders, particularly primary headaches like migraine and tension-type headache, still remain underdiagnosed and undertreated despite their high prevalence and significant impact on quality of life. In recent years, several specific medications targeting key pathways in the pathophysiology of migraine have been developed. Despite this advancement, numerous studies indicate that non-steroidal anti-inflammatory drugs (NSAIDs) and analgesics remain the most commonly used drugs. This study focused on the use of NSAIDs and simple analgesics as acute treatments for migraine among patients at a tertiary headache center. Methods: A retrospective observational study was conducted at the Fondazione Policlinico Universitario Campus Bio-Medico throughout 2022. Data were collected on the type and frequency of headaches, the usage and dosage of NSAIDs and other medications, and changes in their use at follow-up visits. Statistical analyses were performed to evaluate the efficacy and determinants of NSAID consumption and headache frequency changes. Results: Two hundred and eightythree patients diagnosed with migraine undergoing their first examination at our center were enrolled. Initially, 58.7% of patients used NSAIDs or simple analgesics, which decreased to 46.6% 3 months after, while triptan use increased from 65.1 to 72.8%. Changes in prophylactic therapies were significantly associated with a decrease in NSAID intake (W = 834.000, p = 0.004) and in headache frequency (W = 5960.5, p = 0.003). Specifically, the addition of topiramate or amitriptyline was associated with a reduction in NSAID use and headache frequency. Even pain freedom after the intake of NSAIDs improved from 55.2 to 79.4% of cases at follow-up. Conclusion: The study highlights the importance of appropriate diagnosis and tailored treatment strategies in the management of primary headaches. It underscores the need for specialized care to enhance treatment efficacy and patient outcomes, demonstrating that adjustments in prophylactic therapy can significantly reduce NSAID intake and improve headache care. This reinforces the role of tertiary headache centers in providing specialized care that can adapt treatments to individual patient needs and improve overall headache management.

Background and Purpose: Fremanezumab, a monoclonal antibody targeting the calcitonin gene‐related peptide for migraine prevention, is available in monthly (225 mg) and quarterly (675 mg) doses. Previous studies showed efficacy and safety for both regimens, but a real‐life comparison is lacking. This study aimed to compare the effectiveness and safety of monthly and quarterly fremanezumab in a real‐life setting. Methods: This Italian, prospective, multicenter study enrolled 95 migraine patients. During a 3‐month treatment period, patients received either monthly or quarterly fremanezumab (49 monthly, 46 quarterly). A 6‐month treatment period involved 79 patients (43 monthly, 36 quarterly). Monthly headache (MHD) and migraine days (MMD), number of days (AMD) and pills (AMP) of acute medication intake, and Headache Impact Test (HIT‐6), Migraine Disability Assessment (MIDAS) test, and Numeric Rating Scale (NRS) scores were recorded at baseline and after 3 and 6 months of treatment. Adverse events (AEs), responder rates, and medication overuse were also investigated. Results: Both monthly and quarterly treatments led to significant reductions in MMD, MHD, AMP, AMD, HIT‐6, MIDAS, and NRS scores after 3 and 6 months. The monthly regimen exhibited a slightly greater reduction in MMD and MHD after the first quarter, with no significant difference observed after 6 months. The most common AE was transient injection‐site reaction, without between‐group differences. Responder rates and resolution of medication overuse did not significantly differ between the groups. Conclusions: Both monthly and quarterly regimens were effective and safe, with a tendency for an advantage of the monthly regimen only in the first quarter of treatment. [ABSTRACT FROM AUTHOR]

Intravenous thrombolysis (IT) and mechanical thrombectomy (MD) are the two interventional approaches that have changed the outcome of patients with acute ischemic stroke (AIS). Ipsilateral and contralateral carotid stenosis (ICS, CCS) play an important role in regulating cerebral hemodynamics, both in chronic and acute situations such as AIS. Several studies have explored their role in the incidence and severity of stroke, but very few have investigated the possible impact of ICS and CCS on the efficacy of interventional procedures. The purpose of this review was to I) highlight the incidence and prevalence of carotid stenosis (CS); II) assess the impact of ICS and CCS on cerebral hemodynamics; III) evaluate the effect of carotid stenosis on the efficacy of interventional therapies (IT and MT) for AIS; and IV) report therapeutic complications related to CS. We searched PubMed/Medline for case reports, reviews, and original research articles on English-language review topics during the period from January 1, 2000 to October 1, 2023. CS is associated with 15–20 % of the total number of AIS. ICS and CCS had a negative influence on both cerebral hemodynamics before AIS and outcome after interventional procedures (IT, MT alone or in bridging). Available data on cerebral hemodynamics and efficacy of interventional therapies for AIS suggest a negative role of CS. Therefore, early diagnosis of CS may be considered relevant to preventive and post-stroke treatment strategies. [ABSTRACT FROM AUTHOR]

Background: Chronic migraine (CM) is a disabling and hard-to-treat condition, associated with high disability and high cost. Among the preventive treatments, botulinum toxin A (BoNT-a) and monoclonal antibodies against the calcitonin gene-related protein (anti-CGRP mAbs) are the only disease-specific ones. The assessment of the disease burden is complex, and among others, tools such as the allodynia symptoms checklist (ASC-12) and headache impact test (HIT-6) are very useful. This exploratory study analysed the impact of these two therapies on migraine burden. Methods: The RAMO study was a multicentre, observational, retrospective investigation conducted in two headache centres: the Fondazione IRCCS Istituto Neurologico Carlo Besta (Milan) and the Fondazione Policlinico Campus Bio-Medico (Rome). This study involved patients with chronic migraine treated with mAbs or BoNT-A. We conducted a subgroup exploratory analysis on HIT-6 and ASC-12 scores in the two groups. The Wilcoxon rank-sum test, Fisher's exact test, and ANOVA were performed. Results: Of 126 patients, 36 on mAbs and 90 on BoNT-A had at least one available follow-up. mAbs resulted in a mean reduction of −11.1 and −11.4 points, respectively, in the HIT-6 at 6 and 12 months, while BoNT-A was reduced −3.2 and −3.6 points, respectively; the mAbs arm resulted in mean reductions in ASC-12 at 6 and 12 months of follow-up of −5.2 and −6.0 points, respectively, while BoNT-A showed lesser mean changes of −0.5 and −0.9 points, respectively. The adjusted analysis confirmed our results. Conclusions: In this exploratory analysis, anti-CGRP mAbs showed superior effectiveness for HIT-6 and ASC12 compared to BoNT-A. Reductions in terms of month headache days (MHD), migraine disability assessment test (MIDAS), and migraine acute medications (MAM) were clinically relevant for both treatments.

Background: Psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA) are inflammatory diseases with shared genetic backgrounds and clinical comorbidities. Headache, a common global health issue, affects over 50% of adults and encompasses various types, including migraine, tension-type, and cluster headaches. Migraine, the most prevalent, recurrent, and disabling type, is often associated with other medical conditions such as depression, epilepsy, and psoriasis, but little is known about the relationship between autoimmune disease and the risk of migraine. Methods: A cross-sectional study was conducted from July to November 2022, enrolling 286 participants, including 216 with PsA, 70 with axSpA, and 87 healthy controls. Results: Headache prevalence was significantly higher in the PsA (39.81%) and axSpA (45.71%) patients compared to the healthy controls. The prevalence of migraine without aura was also significantly higher in both the PsA (18.52%) and axSpA (28.57%) groups compared to the healthy controls. Conclusions: These findings underscore the high burden of headache and migraine in PsA and axSpA participants, highlighting the need for improved management and treatment strategies for these patients.

The new Calcitonin Gene-Related Peptide (CGRP)-targeted therapies have proven high efficacy and tolerability in episodic and chronic migraine. Eptinezumab is a humanized monoclonal antibody that selectively binds CGRP with high affinity. Eptinezumab was approved by the Food and Drug Administration on February 21st, 2020, for the preventive treatment of migraine in adults. It is administered intravenously over 30 minutes with a standard dose of 100 mg and has a T-max of 30 minutes-1 hour and a half-life of 27 days. These pharmacological properties allow for a very rapid onset of effect and a quarterly administration. It is the first time that a preventive treatment for migraine can be offered as an intravenous administration. As the range of therapeutic possibilities in migraine is expanding, the treatment process must include common decision-making, where physicians should explain in detail to patients the different characteristics of treatment options beyond efficacy and side effects. Patients can now express a preference on a range of opportunities: pharmacological versus non-pharmacological approaches, route of administration, frequency of administration, efficacy, rapidity, side effects, costs, the possibility of titration or dosing, and durability of effectiveness at suspension. Also, patient preferences can be influenced by age, country, migraine severity, and earlier experience with CGRP-targeted therapies. Besides, adherence may be influenced by several factors, including route and the schedule of administration. This narrative review describes a new perspective from the patient's point of view. Clinicians should ally with patients to select treatments that meet each patient's needs and thus apply a tailored approach, addressing not only headaches. In this way, physicians would care for the patients globally and stand out their preferences on different aspects of treatment. Besides, healthcare professionals shall be aware that patients' beliefs about therapies are subject to change with increasing experience with new therapeutic approaches. [ABSTRACT FROM AUTHOR]

The calcitonin gene-related peptide (CGRP) is a neuropeptide widely distributed throughout the human body. While primarily recognized as a nociceptive mediator, CGRP antagonists are currently utilized for migraine treatment. However, its role extends far beyond this, acting as a regulator of numerous biological processes. Indeed, CGRP plays a crucial role in vasodilation, inflammation, intestinal motility, and apoptosis. In this review, we explore the non-nociceptive effects of CGRP in various body systems, revealing actions that can be contradictory at times. In the cardiovascular system, it functions as a potent vasodilator, yet its antagonists do not induce arterial hypertension, suggesting concurrent modulation by other molecules. As an immunomodulator, CGRP exhibits intriguing complexity, displaying both anti-inflammatory and pro-inflammatory effects. Furthermore, CGRP appears to be involved in obesity development while paradoxically reducing appetite. A thorough investigation of CGRP's biological effects is crucial for anticipating potential side effects associated with its antagonists' use and for developing novel therapies in other medical fields. In summary, CGRP represents a neuropeptide with a complex systemic impact, extending well beyond nociception, thus offering new perspectives in medical research and therapeutics [ABSTRACT FROM AUTHOR]

(1) Background: Randomized controlled trials and real-life studies demonstrated the efficacy of OnabotulinumtoxinA (OBT-A) for CM prevention. However, no studies specifically addressed its effect on pain's quantitative intensity and qualitative characteristics. (2) Methods: This is an ambispective study: a post-hoc retrospective analysis of real-life prospectively collected data from two Italian headache centers on CM patients treated with OBT-A over one year (i.e., Cy1-4). The primary endpoint was the changes in pain intensity (Numeric Rating Scale, NRS; the Present Pain Intensity (PPI) scale, the 6-point Behavioral Rating Scale (BRS-6)) and quality scale (the short-form McGill Pain Questionnaire (SF-MPQ)) scores. We also assessed the relationship between changes in intensity and quality of pain and disability scale (MIDAS; HIT-6) scores, monthly headache days (MHDs), and monthly acute medication intake (MAMI) (3) Results: We retrieved 152 cases (51.5 years SD 11.3, 80.3% females). From baseline to Cy-4, MHDs, MAMI, NRS, PPI, and BRS-6 scores decreased (consistently p < 0.001). Only the throbbing (p = 0.004), splitting (p = 0.018), and sickening (p = 0.017) qualities of pain collected in the SF-MPQ were reduced. Score variations in MIDAS related to those in PPI scales (p = 0.035), in the BRS-6 (p = 0.001), and in the NRS (p = 0.003). Similarly, HIT-6 score changes related to PPI score modifications (p = 0.027), in BRS-6 (p = 0.001) and NRS (p = 0.006). Conversely, MAMI variation was not associated with qualitative or quantitative pain score modifications except BRS-6 (p = 0.018). (4) Conclusions: Our study shows that OBT-A alleviates migraine by reducing its impact on multiple aspects, such as frequency, disability, and pain intensity. The beneficial effect on pain intensity seems specific to pain characteristics related to C-fiber transmission and is associated with a reduction in migraine-related disability.

Introduction: The mechanisms subtending the increased stroke risk in migraine with aura (MA) are not fully understood. Our study aims to evaluate if the clinical profile in stroke patients with MA differentiates from those without MA. Methods: We retrieved the prospective registered electronic clinical dossiers of adult patients younger than 60 years with acute ischemic stroke admitted in four hospitals between January 2016 and June 2022. Patients were classified by the history of MA (MA+ and MA-). Results: We identified 851 stroke patients (59 MA+, 6.9%). Compared to MA-, MA+ patients were characterized by younger age (44.0 ± 10.6 vs 50.1 ± 8.2 years), female sex (59.3% vs 29.0%), and affected by cryptogenic (OR 2.594 95% CI 1.483-4.537), and cerebellar stroke (OR 3.218 95% CI 1.657-6.250; p ≤ 0.001 for all comparisons). After adjusting for age and sex, MA+ patients presented less frequently hypertension (OR 0.349 95% CI 0.167-0.470; p=0.005) and dyslipidemia (OR 0.523 95% CI 0.280-0.974; p = 0.041). After adjusting also for risk factors, the MA+ group had less frequently symptomatic large vessel stenosis (OR 0.126 95% CI 0.017-0,924; p = 0.042) and clinical atherosclerosis (OR 0.103 95% CI 0.014-0.761; p = 0.026), while intima-media thickness did not differ (p = 0.395). Discussion: Cryptogenic and cerebellar stroke and fewer vascular risk factors and clinical atherosclerosis seem to characterize stroke patients with MA. [ABSTRACT FROM AUTHOR]

Background and Purpose: To evaluate the 1‐year effectiveness and tolerability of galcanezumab in real life and the prognostic indicators of persistent response. Methods: High‐frequency episodic migraine (HFEM) and chronic migraine (CM) patients treated with galcanezumab who completed a 1‐year observation were enrolled. The primary outcomes assessed during the 12 months (V1–V12) were the change in monthly migraine days (MMDs) from baseline and the response rates ≥50% in MMDs (MMD ≥50% RR). The secondary outcomes were changes in pain intensity (numerical rating scale [NRS]) and in monthly acute medication intake (MAMI). Results: We enrolled 191 patients (77.5% CM). Twenty‐three patients (12%) dropped out, two for nonserious adverse events. At least 40% of patients took add‐on standard preventives from baseline to V12. At V12, MMDs were reduced by 6.0 days in HFEM and by 11.9 days in CM patients (both p < 0.00001); NRS and MAMI were also decreased in both groups (p < 0.00001). One‐hundred eight (56.5%) patients presented MMD ≥50% RR for 9 cumulative months (interquartile range=8): we defined this value as the cutoff for a persistent response. Persistent responders were less likely to have a higher body mass index (BMI) (p = 0.007) but more frequently had a good response to triptans (p = 0.005) and MMD ≥50% RR at V1 (p < 0.0000001). Patients without a persistent response were on add‐on therapy for longer periods of time (p < 0.001). Conclusions: Galcanezumab was effective and well‐tolerated in the 1‐year term, with most patients presenting MMD ≥50% RR for at least 9 months. Triptan response, lower BMI, and MMD ≥50% RR in the first month emerged as predictive factors for a persistent response. [ABSTRACT FROM AUTHOR]

Objective: This prospective cohort, real‐life study aimed to evaluate whether galcanezumab, a monoclonal antibody anti‐calcitonin gene‐related peptide (CGRP) ligand, can reduce caregivers' distress and improve their mutuality with patients. Background: Migraine is a highly disabling chronic disease that negatively impacts patients' and often their relatives' lives, occurring during an active phase of life with direct consequences on leisure‐ and work‐related activities. The figure of caregiver is crucial in several neurological conditions but poorly accounted for in migraine care so far. Studies on monoclonal antibodies against the CGRP pathway, recently introduced as migraine‐preventive treatments, demonstrated that they significantly reduce migraine frequency and disability in the first weeks of treatment. Methods: Consecutive patient‐caregiver dyads were evaluated at baseline and after 6 months of treatment with galcanezumab (V6) at our headache center from September 2020 to September 2021. Enrolled patients were requested to report their monthly migraine days, monthly intake of acute medications, attack pain intensity (on the Numeric Rating Scale), concomitant preventives, and disability questionnaires (Headache Impact Test, Migraine Disability Assessment). Each dyad filled in the Mutuality Scale to check their reciprocity; moreover, the Relatives' Stress Scale was used to detect caregivers' distress. Results: We enrolled 27 patient‐caregiver dyads. At 6 months, migraine burden significantly improved with reductions in monthly migraine days (falling from 14.8 [SD = 4.8] days by 10.3 [SD = 4.8] days; 95% CI: 8.4, 12.2; p < 0.001) and Migraine Disability Assessment scores (lowering from 83.6 [SD = 46.7] by 71.5 points [SD = 49.3]; 95% CI: 51.2, 91.9; p < 0.001). From baseline to month 6, the caregiver Relatives' Stress Scale score significantly decreased (falling from 20.7 [SD = 13.7] by 6.5 [SD = 14.1] points; 95% CI: 0.8, 12.2; p = 0.027), while the Mutuality Scale's caregiver total score increased (from 3.04 [SD = 0.61] by 0.29 [SD = 0.49] points; 95% CI: −0.508, −0.064; p = 0.014). Conclusions: Our findings preliminarily demonstrated that patients' migraine improvement after 6 months of galcanezumab treatment could be favorably perceived by caregivers, significantly reducing their distress with better reciprocity within the dyad.

Calcitonin gene-related peptide (CGRP) is probably the most potent vasodilator in cerebral circulation. Forty years after its discovery, the new CGRP-targeted therapy monoclonal antibodies, and the small molecule gepants, are now available for clinical practice. While randomized controlled trials and real-world experience consistently demonstrated the high efficacy and tolerability of monoclonal antibodies, limited evidence is available to characterize gepants fully. Depending on pharmacokinetics, these CGRP receptor antagonists can be used for acute (ubrogepant, rimegepant, and the not yet approved zavegepant) or preventive (atogepant and rimegepant) migraine treatment. Randomized placebo-controlled trials demonstrated gepants efficacy in treating acute attacks to obtain 2 h pain freedom in about 20% of patients and pain relief in about 60%, while up to 60% of treated patients with episodic migraine may experience a 50% reduction in monthly migraine days. The most common treatment-related emergent adverse events were gastrointestinal (nausea, constipation) for the acute or preventive use. No vascular or hepatic concerns have emerged so far. More studies are ongoing to investigate gepant tolerability and safety also if associated with monoclonal antibodies targeting CGRP and other therapeutic classes. Gepants are also under investigation to treat other painful and non-painful conditions. Real-life studies are necessary to confirm the trials' findings and investigate more practical clinical aspects. [ABSTRACT FROM AUTHOR]

Italian Migraine Registry (I-GRAINE) is a multicenter (n = 38), prospective, observational, non-interventional study aimed at providing big data on migraine to ensure proper clinical disease management, according to scientific, and sustainability criteria. We enrolled consecutive patients affected by episodic or chronic migraine according to the systematic random method. Information on sociodemographic characteristics, lifestyle, migraine features, patient's journey, and healthcare resource use were gathered using face-to-face interviews.On the date of 31 December 2021, we enrolled 231 patients at 12 headache centers. Most of them were women (84.4%), with high migraine frequency (9.6 ± 6.9 days/month) and severe disability (MIDAS score: 43.0 ± 40.8; HIT-6 score: 60.4 ± 10.6). Only a minority of patients (38.1%) had previously visited a headache center.A clear-cut difference emerged in the proportion of responders to nonspecific acute treatments (43.5-66.7%) compared to triptans (76.3%) and in responders to unspecific prophylaxis (5.4-35%) compared to anti-CGRP monoclonal antibodies (69.2-78.6%). Most patients underwent ≥ 1 specialist visit (66.9%) or diagnostic investigation (77.4%) over the last 3 years-mostly subsidized by our national health system-inappropriate in 64.9% and 25% of the cases, respectively.The I-GRAINE registry is expected to provide a large and exponentially increasing collection of clinical, biological, and epidemiologic information and will contribute to moving migraine out of the shadow cone of marginalization, which has been often relegated up to now.
