Migraine and treatment

The beneficial effects of increasing histamine levels on memory have acquired special interest due to their applicability to psychiatric conditions that cause memory impairments. In addition, by employing drug repurposing approaches, it was demonstrated that dihydroergotamine (DHE), an FDA drug approved to treat migraines, inhibits Histamine N Methyl Transferase (HNMT), the enzyme responsible for the inactivation of histamine in the brain. For this reason, in the present work, the effect of DHE on histamine levels in the hippocampus and its effects on memory was evaluated, employing the scopolamine-induced amnesia model, the Novel Object Recognition (NOR) paradigm, and the Morris Water Maze (MWM)...

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most common monogenic form of cerebral small vessel disease, caused by a mutation in the NOTCH3 gene on chromosome 19. The main clinical features include migraine (often with aura), early onset, recurrent subcortical ischemic strokes, mood disturbances, and cognitive impairment, frequently leading to dementia and disability with a reduction in life expectancy. Cerebral chronic global hypoperfusion, due to impaired cerebrovascular reactivity, seems to play a primary role in CADASIL...

Calcitonin gene-related peptide (CGRP) and nitric oxide (NO) have been recognized as important mediators in migraine but their mechanisms of action and interaction have not been fully elucidated. Monoclonal anti-CGRP antibodies like fremanezumab are successful preventives of frequent migraine and can be used to study CGRP actions in preclinical experiments. Fremanezumab (30 mg/kg) or an isotype control monoclonal antibody was subcutaneously injected to Wistar rats of both sexes. One to several days later, glyceroltrinitrate (GTN, 5 mg/kg) mimicking nitric oxide (NO) was intraperitoneally injected, either once or for three consecutive days...

Stroke is the chief differential diagnosis in patient presenting to the emergency room with abrupt onset focal neurological deficits. Neuroimaging, including non-contrast computed tomography (CT), magnetic resonance imaging (MRI), vascular and perfusion imaging, is a cornerstone in the diagnosis and treatment decision-making. This review examines the current state of evidence behind the different imaging paradigms for acute ischemic stroke diagnosis and treatment, including current recommendations from the guidelines...

BACKGROUND: Approximately 15% of migraine sufferers need preventative medicine because they have more than two episodes each month. Migraine is a regular, persistent condition that frequently makes victims helpless. Numerous drugs from various classes have so far been used in migraine prophylaxis. Their effectiveness is recurrently overshadowed by their side effects because they must be used for a long time, which occasionally necessitates stopping the drug. MATERIALS AND METHODS: In the tertiary care teaching hospital's department of medicine, a prospective, comparative, open-label study was initiated...

Inhibition of calcitonin gene-related peptide (CGRP) or its cognate CGRP receptor (CGRPR) has arisen as a major breakthrough in the treatment of migraine. However, a second CGRP-responsive receptor exists, the amylin (Amy) 1 receptor (AMY1 R), yet its involvement in the pathology of migraine is poorly understood. AMY1 R and CGRPR are heterodimers consisting of receptor activity-modifying protein 1 (RAMP1) with the calcitonin receptor (CTR) and the calcitonin receptor-like receptor (CLR), respectively. Here, we present the structure of AMY1 R in complex with CGRP and Gs protein and compare it with the reported structures of the AMY1 R complex with rat amylin (rAmy) and the CGRPR in complex with CGRP...

OBJECTIVE: Exploring the libido status of male chronic headache patients and analyzing its relationship with headache symptoms, sleep, anxiety, and depression, providing reference for the comprehensive treatment of male chronic headache. METHODS: 179 patients with chronic headache who visited the Third Affiliated Hospital of Qiqihar Medical College from January 2022 to February 2023 were selected. The male Self Rated Libido Scale , Visual Analog Scale for Pain, Migraine Disability Assessment Scale, Pittsburgh Sleep Quality Index, Generalized Anxiety Disorder Scale-7, and Patient Health Questionnaire-9 were used to evaluate the libido status, headache severity, disability level, sleep quality, anxiety, and depression of the research subjects, respectively...

Recently, calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAbs) have become available as a prophylactic treatment for migraine and have shown high efficacy and safety in clinical practice. CGRP mAbs have been reported to be effective not only for migraine but also for other comorbidities, such as psychiatric complications in patients with migraine. However, there are no reports examining the effect of CGRP mAbs on dystonia. We treated a patient with comorbid migraine and focal task-specific dystonia (writer's cramp) with a CGRP mAb (erenumab) because of an increase in monthly migraine days despite the addition of migraine prophylaxis...

OBJECTIVE: To compare various exercise modalities' efficacy on migraine frequency, intensity, duration, and disability. BACKGROUND: Exercise has been shown to be an effective intervention to reduce migraine symptoms and disability; however, no clear evidence exists regarding the most effective exercise modalities for migraine treatment. METHODS: A systematic review was performed in PubMed, PEDro, Web of Science, and Google Scholar. Clinical trials that analyzed the efficacy of various exercise modalities in addressing the frequency, intensity, duration, and disability of patients with migraine were included...

Human blood vessel organoids (hBVOs) offer a promising platform for investigating vascular diseases and identifying therapeutic targets. In this study, we focused on in vitro modeling and therapeutic target finding of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), the most common form of hereditary stroke disorder caused by mutations in the NOTCH3 gene. Despite the identification of these mutations, the underlying pathological mechanism is elusive, and effective therapeutic approaches are lacking...

Visual snow syndrome (VSS) is a rarely diagnosed neurological phenomenon. It is a visual disorder characterised by the presence of numerous white, black, or translucent dots in the visual field, resembling the 'snow' of an analogue TV set experiencing reception interference. According to The International Classification of Headache Disorders, 3rd edition, visual snow is defined as a pattern of continuous small dots across the visual field lasting >3 months and accompanied by at least two of the following four additional symptoms: palinopsia, increased entoptic phenomena, photophobia, and nyctalopia...

Psychological, social, and biological aspects contribute synergistically to the maintenance and chronicity of pain in primary headaches. An integrated intervention seems to be the most appropriate in the management of these conditions, taking advantage not only of pharmacological strategies, but also of different approaches according to the global assessment and patient necessities. In this perspective, non-pharmacological treatments are becoming increasingly used to overcome these issues also in paediatric migraine treatment...

Despite its rarity, cluster headache can affect children. Patients with cluster headaches often experience symptoms in their adolescence, but the time it takes for a correct diagnosis can be very long. Cluster headache can be mistaken for other pathologies, which can result in patients being diagnosed and treated incorrectly. CH therapy often represents a challenge in pediatric age as there are no studies dedicated to this age category and the therapy strategy is generally based on data from adult experience...

AIMS: Migraine is the most common disabling headache disorder and is characterized by recurrent throbbing head pain and symptoms of photophobia, phonophobia, nausea, and vomiting. Rimegepant 75mg, an oral lyophilisate calcitonin gene-related peptide antagonist, is the first treatment approved for both the acute and preventative treatment of migraine, and the first acute therapy approved in over 20-years. The objective was to assess the cost-utility of rimegepant compared with best supportive care (BSC) in the UK, for the acute treatment of migraine in the adults with inadequate symptom relief after taking at least 2 triptans, or for whom triptans are contraindicated or not tolerated...

BACKGROUND: Although nerve decompression surgery is an effective treatment for refractory occipital neuralgia (ON), a proportion of patients experience recurrence of pain and undergo reoperation. This study analyzes the incidence, risk factors, and outcomes of reoperation following primary greater occipital nerve (GON) decompression. METHODS: 215 patients who underwent 399 primary GON decompressions were prospectively enrolled. Data included patient demographics, past medical and surgical history, reoperation rates, intraoperative findings, surgical technique, and postoperative outcomes in terms of pain frequency (days/month), duration (hours/day), intensity (scale 0-10), and migraine headache index (MHI)...

Patent Foramen Ovale (PFO) is a remnant of fetal circulation that could be observed in the 25% of the population worldwide. PFO is associated to numerous clinical conditions as migraines, coronary embolization, transient ischemic attacks, and stroke. The main PFO concerns are related to its correlation to stroke, in particular in young adults. Despite the impact on morbidity that PFO could have, to date there is not clear evidence about its management and treatment. In this narrative review our aim is to summarize the more recent evidence in the literature dealing with PFO, in order to provide an updated overview on this topic...
