New-onset headache following COVID-19: An Italian multicentre case series.

OBJECTIVE: To describe the characteristics of patients with new-onset headache following SARS-CoV-2 infection. BACKGROUND: SARS-CoV-2 infection leads to several neurological manifestations, and headache is a frequent and disabling symptom, both exacerbating pre-existing headache syndromes and causing new-onset ones. METHODS: Patients with new-onset headache after SARS-CoV-2 infection with consent to participate were included, while those ones with previous headaches were excluded. The temporal latency of headache after infection, pain characteristics, and concomitant symptoms were analysed. Moreover, the efficacy of acute and preventive medications was explored. RESULTS: Eleven females (median age 37.0 [10.0-60.0] years old) were included. In most cases, headache onset occurred with the infection, the location of pain varied, and the quality was either pulsating or tightening. Headache was persistent and daily in 8 patients (72.7%), while it occurred in episodes in the remaining subjects. Baseline diagnoses were new daily persistent headache (36.4%), probable new daily persistent headache (36.4%), probable migraine (9.1%), and migraine-like headache secondary to COVID-19 (18.2%). Ten patients received one or more preventive treatments and six of them showed an improvement. CONCLUSION: New-onset headache following COVID-19 is a heterogenous condition with uncertain pathogenesis. This type of headache can become persistent and severe, with a wide spectrum of manifestations (new daily persistent headache being the most represented one) and variable response to treatment.

Impact of COVID-19 Pandemic Lockdown on Migraine Patients in Latin America.

The coronavirus (COVID-19) pandemic, confinement, fear, lifestyle changes, and worldwide health care impacted almost all diseases. Reports from countries outside Latin America revealed differences in migraine patients. In this study, we describe and compare the immediate changes in migraine symptoms associated with COVID-19 quarantine in patients from Argentina, Mexico, and Peru. An online survey was conducted from May to July 2020. The survey was answered by 243 migraine patients, with questions related to sociodemographic data, quarantine conditions, changes in working conditions, physical activity, coffee intake, healthcare access, acute migraine medication use, symptoms of anxiety, depression, and fear of COVID-19. The results show that 48.6% of migraine patients experienced worsened symptoms, 15.6% improved, and 35.8% remained unchanged. Worsening migraine symptoms were associated with staying at home during the lockdown. Intake of analgesics was associated with an increase in migraine symptoms of 18 times relative to those who did not increase their intake. Migraine symptoms improved when the number of sleep hours was increased, and we observed an improvement when patients decreased analgesic intake. The uncertainty about the end of the pandemic, the news, and social media are three items that contributed to the worsening of migraine symptoms in patients in the three investigated countries. Confinement during the first pandemic wave in Latin America harmed migraine patients who stayed home during the lockdown.

Results of a Web-Based Survey on 2105 Greek Migraine Patients-Second Part: Efficacy of Acute and Prophylactic Migraine Treatments and Corresponding Patients' Reported Satisfaction.

Background and Objectives: The Greek Society of Migraine and Headache Patients conducted, in 2020, its second online survey, titled "Migraine in Greece-2020", after publication of the first similar online survey conducted in 2018. To compare the current findings with the corresponding data obtained in 2018, we herein release the second part of results obtained from the 2020 survey on the efficacy of preventive and symptomatic anti-migraine medications and the patients' reported satisfaction with these treatments. Materials and Methods: We surveyed 2105 migraine patients from all over Greece with the use of a 151-questions specific migraine-focused questionnaire in Greek language, which was distributed through the online research software "SurveyMonkey". Results: Triptans were mostly used with efficacy for the symptomatic relief of migraine attacks. About 2 of 3 surveyed patients had received various prophylactic oral medications and the majority of them discontinued these prophylactic medications as a result of inefficacy/safety issues. BoNTA was reported to be effective only when administration was commenced by a trained neurologist/headache specialist, while our current findings are generally comparable to those obtained in our 2018 pre-COVID-19 survey and the pandemic has not imposed any significant attitudes on migraine therapies and corresponding patients' satisfaction. Conclusion: Although a market change is anticipated with the evolving widespread use of anti-CGRPs monoclonal antibodies or gepants in the symptomatic and prophylactic treatment of migraine, it is of great interest to review published results of larger longitudinal population-based studies to further ascertain the satisfaction of patients to migraine therapies.

Post-vaccination headache reporting: Trends according to the Vaccine Adverse Events Reporting System.

OBJECTIVE: To assess the characteristics and associated disability of headache as an adverse event following vaccination. BACKGROUND: According to clinical trials and post-licensure surveillance, headache is a common symptom of vaccines, yet systematic investigations of post-licensure reports of this adverse event are lacking. METHODS: This was a retrospective database analysis study. We searched the Vaccine Adverse Events Reporting System (VAERS) database completed from July 1990 to June 2020 (a 30-year period prior to the start of COVID-19 pandemic) to identify reports of headache. We evaluated epidemiological features, including event characteristics, patient demographics, and vaccine type. RESULTS: In those aged 3 years or older, headache was the fifth most reported adverse symptom, present in 8.1% (43,218/536,120) of all reports. Of headache reports, 96.3% (41,635/43,218) included the code "headache" not further specified. Migraine was coded in 1973 cases, although almost one-third (12,467/41,808; 29.8%) of headache reports without a migraine code mention nausea or vomiting. The onset of symptoms was within 1 day of vaccination in over two-thirds of cases. The majority of reports were classified as not serious; about one-third involved emergency room or office visits. Of the 43,218 total headache reports, only a minority involved hospitalizations (2624; 6.1%) or permanent disability (1091; 2.5%), females accounted for 68.9% (29,771) and males for 29.5% (12,725), patients aged 6 to 59 years represented 67.3% (29,112), and over one-third of cases were reported after herpes zoster (8665; 20.1%) and influenza (6748; 15.6%) vaccinations. CONCLUSION: In a national surveillance system, headache was a commonly reported post-vaccination adverse event; a small subset of reports was considered serious. The development of standardized vaccine-related case definitions could be useful for better evaluating headache as an adverse event during vaccine development, and may reduce vaccine hesitancy especially in headache-prone individuals.

Headache attributed to SARS-CoV-2 infection, vaccination and the impact on primary headache disorders of the COVID-19 pandemic: A comprehensive review.

OBJECTIVE: The objective is to summarize the knowledge on the epidemiology, pathophysiology and management of secondary headache attributed to SARS-CoV-2 infection and vaccination; as well as to delineate their impact on primary headache disorders. METHODS: This is a narrative review of the literature regarding primary and secondary headache disorders in the setting of COVID-19 pandemic. We conducted a literature search in 2022 on PubMed, with the keywords "COVID 19" or "vaccine" and "headache" to assess the appropriateness of all published articles for their inclusion in the review. RESULTS: Headache is a common and sometimes difficult-to-treat symptom of both the acute and post-acute phase of SARS-CoV-2 infection. Different pathophysiological mechanisms may be involved, with the trigeminovascular system as a plausible target. Specific evidence-based effective therapeutic options are lacking at present. Headache attributed to SARS-CoV-2 vaccinations is also common, its pathophysiology being unclear. People with primary headache disorders experience headache in the acute phase of COVID-19 and after vaccination more commonly than the general population. Pandemic measures, forcing lifestyle changes, seemed to have had a positive impact on migraine, and changes in headache care (telemedicine) have been effectively introduced. CONCLUSIONS: The ongoing COVID-19 pandemic is a global challenge, having an impact on the development of secondary headaches, both in people with or without primary headaches. This has created opportunities to better understand and treat headache and to potentiate strategies to manage patients and ensure care.

Headache following vaccination against COVID-19 among healthcare workers with a history of COVID-19 infection: A cross-sectional study in Iran with a meta-analytic review of the literature (preprint)

Background: There is evidence of the occurrence of headache after vaccination against COVID-19. However, only a few studies have examined the headache characteristics and related determinants, especially among healthcare workers with a history of COVID-19 infection. Methods: We evaluated the incidence of headaches after injection of different types of COVID-19 vaccine to determine factors relating to the incidence of headache after vaccination among the Iranian healthcare workers who had previously contracted COVID-19. A group of 334 healthcare workers with a history of COVID-19 infection were included and vaccinated (at least one month after recovery without any COVID-19 related symptoms) with different COVID-19 vaccines. The baseline information, headache characteristics and vaccine specifications were recorded. Results: Overall, 39.2% reported experiencing a post-vaccination headache. Of those with a previous history of headache, 51.1% reported migraine-type, 27.4% tension-type and 21.5% other types. The mean time between vaccination and headache appearance was 26.78±6.93 h, with the headache appearing less than 24 h after vaccination in most patients (83.2%). The headaches reached its peak within 8.62±2.41 hours. Most patients reported a compression-type headache. The prevalence of post-vaccination headaches was significantly different according to the type of vaccine used. The highest rates were reported for AstraZeneca, followed by Sputnik V. In regression analysis, the vaccine brand, female gender and initial COVID-19 severity were the main determinants for predicting post-vaccination headache. Conclusion: Participants commonly experienced a headache following vaccination against COVID-19. Our study results indicated that this was slightly more common in females and in those with a history of severe COVID-19 infection.

Occipital neuralgia after COVID-19 vaccination: a report of two cases (preprint)

BACKGROUND A wide range of neurological complications has been described following the administration of COVID-19 vaccinations, with headache being the most commonly reported neurological adverse effect, with higher incidence after the second dose. The most common headache is a dull pain or migraine like. Still, two cases of trigeminal neuralgia and a case series of 7 patients with cluster headache who were clinically stable and had a new episode a few days after COVID-19 vaccination have also been reported. Herein, we describe the first two cases of occipital neuralgia developing after COVID-19 vaccination.CASES PRESENTATION Two cases were observed in the neurology outpatient clinic of a tertiary university referral center in Portugal between October 2021 and June 2022. Both patients developed the headache within 1 to 6 days after the second dose of BNT162b2 (Pfizer). One had no previous history of headaches, and the other had a migraine that was clearly different from the present headache. Each case is described, checked for ICHD criteria for occipital neuralgia, and its temporal relation with COVID-19 Vaccination is reported.CONCLUSIONS COVID-19 vaccination can trigger various types of headaches, far beyond the most commonly described feature of dull pain, possibly by activating an immune-inflammatory response.

Triggers and clinical changes of childhood primary headache characteristics during COVID-19 pandemic lockdown.

OBJECTIVE: Children with primary headache are particularly vulnerable to the negative impacts of the pandemic due to factors like increased social isolation, disruption of sleep and impairment of healthy diet. We aimed to investigate the clinical changes and triggering factors for childhood primary headaches to demonstrate the impact of the pandemic lockdown. METHOD: Children aged between 60 months and 18 years with headache complaint attending the general outpatient clinic between December 2019 and December 2020 were included in the study. Patients were classified according to ICHD-3 regarding clinical and laboratory data. Primary headaches diagnosed before (December 2019-March 2020) and during the pandemic lockdown (April 2020-December 2020) were divided into two groups as migraine and tension-type headache (TTH). Clinical picture and triggering factors were compared between groups to illustrate the effect of the lockdown. RESULTS: The study included 612 subjects, with 463 patients (76%) classified in the primary headache group and 149 (24%) in the secondary headache group. Among the first group, 267 patients (58%) had migraine and 196 patients (42%) had TTH. Comparisons between before and during the pandemic lockdown showed significant increased frequency of TTH, but no difference in the frequency and duration of migraine. Both screen exposure and sleep pattern changes were found to be significantly increased in the TTH group during the pandemic lockdown. DISCUSSION: We found a significant increase in the attack frequency for TTH patients during the pandemic lockdown. Reduction in screen time is an important strategy in preventing primary headache attacks in children.

Mint and Menthol: A Review of Potential Health Benefits and wider Human effects (preprint)

Mint and to a lesser extent menthol have been used since antiquity for medicinal purposes. Key components of mint and menthol use such as composition and intake, safety and traditional uses are discussed prior to a review of clinical and human performance outcomes in the areas of digestive and respiratory health; antibacterial and anti-fungal properties, nocioception, migraine and headache and emerging evidence regarding COVID 19. Evidence suggests benefit for patients with irritable bowel syndrome and related digestive issues, with analgesic and respiratory effects also noted. Perceptual characteristics relating to thermal comfort and sensation, taste sensitivity and alertness are also considered; these effects are predominantly driven by stimulation of transient receptor potential melastatin 8 (TRPM8) activity resulting in sensations of cooling and freshness, with lesser influence on thirst. Finally, sport performance is considered as a domain that may further elucidate some of the aforementioned underpinning outcomes due to its systemic and dynamic nature, especially when performed in hot environmental conditions.

Severe acute infection and chronic pulmonary disease are risk factors for developing post-COVID-19 conditions (preprint)

Post-COVID-19 conditions, also known as long COVID, has significantly impacted the lives of many individuals, but the risk factors for this condition are poorly understood. In this study, we performed a retrospective EHR analysis of 89,843 individuals at a multi-state health system in the United States with PCR-confirmed COVID-19, including 1,086 patients diagnosed with long COVID and 1,086 matched controls not diagnosed with long COVID. For these two cohorts, we evaluated a wide range of clinical covariates, including laboratory tests, medication orders, phenotypes recorded in the clinical notes, and outcomes. We found that chronic pulmonary disease (CPD) was significantly more common as a pre-existing condition for the long COVID cohort than the control cohort (odds ratio: 1.9, 95% CI: [1.5, 2.6]). Additionally, long-COVID patients were more likely to have a history of migraine (odds ratio: 2.2, 95% CI: [1.6, 3.1]) and fibromyalgia (odds ratio: 2.3, 95% CI: [1.3, 3.8]). During the acute infection phase, the following lab measurements were abnormal in the long COVID cohort: high triglycerides (meanlongCOVID: 278.5 mg/dL vs. meancontrol: 141.4 mg/dL), low HDL cholesterol levels (meanlongCOVID: 38.4 mg/dL vs. meancontrol: 52.5 mg/dL), and high neutrophil-lymphocyte ratio (meanlongCOVID: 10.7 vs. meancontrol: 7.2). The hospitalization rate during the acute infection phase was also higher in the long COVID cohort compared to the control cohort (ratelongCOVID: 5% vs. ratecontrol: 1%). Overall, this study suggests that the severity of acute infection and a history of CPD, migraine, CFS, or fibromyalgia may be risk factors for long COVID symptoms. Our findings motivate clinical studies to evaluate whether suppressing acute disease severity proactively, especially in patients at high risk, can reduce incidence of long COVID.

Infection and vaccine induced Spike antibody responses against SARS-CoV-2 Variants of concern in immune naïve children and adults (preprint)

A more efficient and effective adaptive humoral immune response has been proposed as the basis of the usually favourable outcome of paediatric COVID-19. The breadth of virus and vaccine immunogenicity towards the ever-mutating Spike protein amongst variants of concern (VOC) have not yet been compared between children and adults. We utilized molecular cloning and sensitive antibody detection against conformational Spike by flow cytometry to assess Spike antibodies and delineate the immunogenic region in immune naïve children and adults vaccinated by BNT162b2 and ChAdOx1, and naturally infected with Early Clade, Delta, and Omicron variants. Patient sera were analysed against SARS-CoV-2 Spike antigens including naturally occurring VOCs Alpha, Beta, Gamma, Delta, Omicron BA.1, BA.2, and BA.5 variants of interest Epsilon, Kappa, Eta, D.2, and artificial Spike mutants. There was no notable difference between breadth and longevity of antibody responses generated against VOCs in children and adults. Vaccinated individuals displayed similar immunoreactivity profiles across variants to naturally infected individuals. Delta-infected patients had an enhanced immunogenicity toward Delta and some VOCs compared to patients infected by Early Clade SARS-CoV-2. Although Omicron BA.1, BA.2, and BA.5 antibody levels were increased after Omicron infection in both children and adults, immunogenicity against Omicron subvariants was reduced. This decrease was observed across VOC infection, immunization, and age groups. Selected epistatically combined mutations led to an increase of immunogenicity in artificial Spikes, but were unable to compensate overall within Omicron. Our results reveal important molecular features central to the generation of high antibody titers and broad immunoreactivity that should be considered in future vaccine design and global serosurveillance.

A Digital Therapeutic Allowing a Personalized Low-Glycemic Nutrition for the Prophylaxis of Migraine: Real World Data from Two Prospective Studies.

Migraine is a headache disorder associated with a high socioeconomic burden. The digital therapeutic sinCephalea provides an individualized low-glycemic diet based on continuous glucose measurement and is intended to provide a non-pharmacological migraine prophylaxis. We performed two prospective studies with migraine patients who used sinCephalea over a period of 16 weeks. The patients used a headache diary and recorded their migraine-related daily life impairments using the assessment tools HIT-6 and MIDAS for a pre versus post comparison. In addition, continuous glucose data of patients were compared to healthy controls. In both studies, patients reported a reduction of headache and migraine days as well as reductions in HIT-6 and MIDAS scores. More specifically, migraine days decreased by 2.40 days (95% CI [-3.37; -1.42]), HIT-6 improved by 3.17 points (95% CI [-4.63; -1.70]) and MIDAS by 13.45 points (95% CI [-22.01; -4.89]). Glucose data suggest that migraine patients have slightly increased mean glucose values compared to healthy controls, but drop into a glucose range that is below one's individual standard range before a migraine attack. In conclusion, sinCephalea is a non-pharmacological, digital migraine prophylaxis that induces a therapeutic effect within the range of pharmacological interventions.

A collaborative approach to improving representation in viral genomic surveillance (preprint)

The lack of routine viral genomic surveillance delayed the initial detection of SARS-CoV-2, allowing the virus to spread unfettered at the outset of the U.S. epidemic. Over subsequent months, poor surveillance enabled variants to emerge unnoticed. Against this backdrop, long-standing social and racial inequities have contributed to a greater burden of cases and deaths among minority groups. To begin to address these problems, we developed a new variant surveillance model geared toward building microbial genome sequencing capacity at universities in or near rural areas and engaging the participation of their local communities. The resulting genomic surveillance network has generated more than 1,000 SARS-CoV-2 genomes to date, including the first confirmed case in northeast Louisiana of Omicron, and the first and sixth confirmed cases in Georgia of the emergent BA.2.75 and BQ.1.1 variants, respectively. In agreement with other studies, significantly higher viral gene copy numbers were observed in Delta variant samples compared to those from Omicron BA.1 variant infections, and lower copy numbers were seen in asymptomatic infections relative to symptomatic ones. Collectively, the results and outcomes from our collaborative work demonstrate that establishing genomic surveillance capacity at smaller academic institutions in rural areas and fostering relationships between academic teams and local health clinics represent a robust pathway to improve pandemic readiness. Author summaryGenomic surveillance involves decoding a pathogens genetic code to track its spread and evolution. During the pandemic, genomic surveillance programs around the world provided valuable data to scientists, doctors, and public health officials. Knowing the complete SARS-CoV-2 genome has helped detect the emergence of new variants, including ones that are more transmissible or cause more severe disease, and has supported the development of diagnostics, vaccines, and therapeutics. The impact of genomic surveillance on public health depends on representative sampling that accurately reflects the diversity and distribution of populations, as well as rapid turnaround time from sampling to data sharing. After a slow start, SARS-CoV-2 genomic surveillance in the United States grew exponentially. Despite this, many rural regions and ethnic minorities remain poorly represented, leaving significant gaps in the data that informs public health responses. To address this problem, we formed a network of universities and clinics in Louisiana, Georgia, and Mississippi with the goal of increasing SARS-CoV-2 sequencing volume, representation, and equity. Our results demonstrate the advantages of rapidly sequencing pathogens in the same communities where the cases occur and present a model that leverages existing academic and clinical infrastructure for a powerful decentralized genomic surveillance system.

Post-COVID Headache: A Literature Review.

PURPOSE OF REVIEW: Post-COVID headache may be unique in presentation and mechanism, often presenting as a new phenotype in patients with a history of a primary headache disorder or resulting in a new headache syndrome in those without history of headache. This review presents a description of the literature published focused on post-COVID headache. Additionally, we discuss potential mechanisms and considerations for treatment of post-COVID headache. RECENT FINDINGS: Headache is one of the most common symptoms of COVID. Common characteristics are revealed when reviewing the phenotypes of headaches that have been described in patients with COVID-19, with most headache phenotypes resembling migraine and new persistent daily headache. Post-COVID headaches are often described as moderate to severe, persistent, and treatment refractory. This review highlights the diversity of presentation of headaches that present as a complication of COVID-19. Treatment of post-COVID headache is challenging, especially in the setting of a pandemic where resources are limited. CLINICAL CASE: A 42-year-old woman with a history of episodic migraine without aura presents over video visit with a new headache type. Her typical headaches are predominantly left sided, throbbing in nature, and associated with photophobia and phonophobia. They are fully relieved by oral sumatriptan 2 h after treatment. She describes this new headache as a constant, pulsating, holocephalic pain with no other migrainous features that have been ongoing for 6 weeks. She notes that the headache has been persistent since that time. She has tried over-the-counter acetaminophen and ibuprofen and her typical migraine abortive therapy without relief. She is debilitated and wonders if there is anything that will take the pain away. She shares that she tested positive for COVID-19 about 2 days prior to headache onset and has associated rhinorrhea, anosmia, and ageusia.

Sleep and sleep-modifying factors in chronic migraine patients during the COVID-19 lockdown.

AIMS: The objective of the present study was to evaluate sleep features and sleep-modifying factors in patients with chronic migraine (CM) during the first Italian COVID-19 lockdown. MATERIAL AND METHODS: The study was based on an e-mail survey addressed to CM patients of our headache center. The survey investigated demographic, life-style, sleep, psychological, and migraine features during the first COVID-19 lockdown period and the month before. The outcomes were sleep quality (measured using PSQI) and variation in sleep quality, duration, and latency. RESULTS: Ninety-two patients were included. The mean PSQI was 11.96. Sleep quality was improved in 14.1%, stable in 47.8%, and worsened in 38.0%. Sleep latency was reduced in 5.4%, stable in 46.7%, and increased in 47.8%. Sleep duration was reduced in 29.3%, stable in 34.8%, and increased in 35.9%. Significant associations were found with age, work/study, remote working, job loss, meal quality change, smoking variation, COVID-19 province prevalence, home-inhabitant relationship, ratio of house size/number of people, stress, state anxiety, anxiety/depression variation, future concern variation, computer hours, internet hours, and television hours. CONCLUSION: The study described sleep features of chronic migraineurs during COVID-19 lockdown, pinpointing the main factors involved in sleep quality and sleep changes. Our findings revealed that migraineurs' sleep was closely linked with life-style and psychological features. Several modifiable factors came to light and they should be considered in order to develop an optimal management of CM. An appropriate and more aware treatment of sleep problems could be a way to improve migraineurs' life.

Vestibular syndromes after COVID-19 vaccination: A prospective cohort study.

BACKGROUND AND PURPOSE: Dizziness and vertigo are common symptoms after COVID-19-vaccination. We aimed to prospectively evaluate objective central or peripheral vestibular function in patients with dizziness, vertigo, and postural symptoms that started or worsened after COVID-19-vaccination. METHODS: Of 4137 patients who presented between January 2021 and April 2022 at the German Center for Vertigo and Balance Disorders, Ludwig Maximilian University of Munich, we identified 72 patients (mean age = 47 years) with enduring vestibular symptoms following COVID-19 vaccination. All underwent medical history-taking, and neurological and neuro-otological workup with bithermal caloric test, video head-impulse test, orthoptics, and audiometry. Diagnoses were based on international criteria. The distribution of diagnoses was compared to a cohort of 39,964 patients seen before the COVID-19 pandemic. RESULTS: Symptom onset was within the first 4 weeks postvaccination. The most prevalent diagnoses were somatoform vestibular disorders (34.7%), vestibular migraine (19.4%), and overlap syndromes of both (18.1%). These disorders were significantly overrepresented compared to the prepandemic control cohort. Thirty-six percent of patients with somatoform complaints reported a positive history of depressive or anxiety disorders. Nine patients presented with benign paroxysmal positional vertigo, three with acute unilateral vestibulopathy, and seven with different entities (vestibular paroxysmia, Ménière disease, polyneuropathy, ocular muscular paresis). Causally related central vestibular deficits were lacking. Novel peripheral vestibular deficits were found in four patients. CONCLUSIONS: Newly induced persistent vestibular deficits following COVID-19 vaccination were rare. The predominant causes of prolonged vestibular complaints were somatoform vestibular disorders and vestibular migraine, possibly triggered or aggravated by stress-related circumstances due to the COVID-19 pandemic or vaccination. An increase of other central or peripheral vestibular syndromes after COVID-19 vaccination was not observed.

Serum alpha-CGRP levels are increased in COVID-19 patients with headache indicating an activation of the trigeminal system (preprint)

Background: Headache is among the most frequent symptoms of acute COVID-19 infection. Its mechanisms remain obscure, but due to its migraine-like characteristics, the activation of the trigeminal system could account for its underlying pathophysiology. Methods: Our aim was to compare the serum levels of CGRP, as a theoretical marker of trigemino-vascular activation, in 25 COVID-19 inpatients with lung involvement experiencing headache with those of 25 matched healthy controls with no headache history. Results: Morning serum alpha-CGRPα levels, as measured by ELISA (Abbexa, UK), were increased in COVID-19 patients with headache (55.2±34.3 pg/mL) vs controls (33.9±14.0 pg/mL) (p<0.01). Conclusions: CGRP levels are increased in COVID-19 patients experiencing headache in the acute phase of this disease, which could explain why headache frequently occurs in COVID-19 and strongly supports a role for trigeminal activation in the pathophysiology of headache in this viral infection.

Hemiplegic Migraine as Cause For Motor Vehicle Collision: A Case Report (preprint)

Introduction: Hemiplegic migraine (HM) is a rare, heterogenous form of migraine characterized by unilateral weakness. This motor aura can present with reversible visual, sensory, and language deficits. HM can be difficult to diagnose due to overlapping presentation with other complex conditions such as multiple sclerosis, seizure disorders, and transient ischemic attack (TIA). Case Presentation: We describe a case of a 40 year old with asymptomatic COVID-19 infection who presented after a motor vehicle collision caused by HM consistent with left sided weakness and loss of consciousness. Conclusions: To date, this is the first description of a patient with known complex migraines to have a motor vehicle collision as a result of HM. The risk of HM-associated neurologic symptoms while driving poses a significant public safety concern. We suggest driving restrictions be considered in patients with HM when migraine aura is present. This case presents support to examine active infection with SARS-CoV-2 as a trigger for HM.
