Background: Anti-CGRP monoclonal antibodies (anti-CGRP MAbs) are approved and available treatments for migraine prevention. Patients do not respond alike and many countries have reimbursement policies, which hinder treatments to those who might respond. This study aimed to investigate clinical factors associated with good and excellent response to anti-CGRP MAbs at 6 months., Methods: European multicentre, prospective, real-world study, including high-frequency episodic or chronic migraine (CM) patients treated since March 2018 with anti-CGRP MAbs. We defined good and excellent responses as ≥50% and ≥75% reduction in monthly headache days (MHD) at 6 months, respectively. Generalised mixed-effect regression models (GLMMs) were used to identify variables independently associated with treatment response., Results: Of the 5818 included patients, 82.3% were females and the median age was 48.0 (40.0-55.0) years. At baseline, the median of MHD was 20.0 (14.0-28.0) days/months and 72.2% had a diagnosis of CM. At 6 months (n=4963), 56.5% (2804/4963) were good responders and 26.7% (1324/4963) were excellent responders. In the GLMM model, older age (1.08 (95% CI 1.02 to 1.15), p=0.016), the presence of unilateral pain (1.39 (95% CI 1.21 to 1.60), p<0.001), the absence of depression (0.840 (95% CI 0.731 to 0.966), p=0.014), less monthly migraine days (0.923 (95% CI 0.862 to 0.989), p=0.023) and lower Migraine Disability Assessment at baseline (0.874 (95% CI 0.819 to 0.932), p<0.001) were predictors of good response (AUC of 0.648 (95% CI 0.616 to 0.680)). These variables were also significant predictors of excellent response (AUC of 0.691 (95% CI 0.651 to 0.731)). Sex was not significant in the GLMM models., Conclusions: This is the largest real-world study of migraine patients treated with anti-CGRP MAbs. It provides evidence that higher migraine frequency and greater disability at baseline reduce the likelihood of responding to anti-CGRP MAbs, informing physicians and policy-makers on the need for an earlier treatment in order to offer the best chance of treatment success., Competing Interests: Competing interests: All authors have completed the ICMJE uniform disclosure form at http://www.icmje.org/disclosure-of-interest/ and declare: EC has received honoraria from Novartis, Chiesi, Lundbeck, MedScape; his salary has been partially funded by Río Hortega grant Acción Estratégica en Salud 2017–2020, Instituto de Salud Carlos III (CM20/00217).

Treatment of migraine attacks is advised in all patients, using non-steroidal anti-inflammatory drugs when the pain is mild and triptans when the pain intensity is moderate-severe. However, the effectiveness of these drugs is moderate, a high percentage of patients have side effects, and triptans are contraindicated in people with a history of stroke, ischaemic heart disease or poorly controlled hypertension. Hence, there is an urgent need for new therapeutic alternatives. In recent years, new drugs for migraine attacks have become available, most notably ditans (lasmiditan) and gepants (ubrogepant and rimegepant). Furthermore, eptinezumab, which has been approved for the preventive treatment of migraine in adults, has also been used for migraine attacks. This manuscript reviews the efficacy and safety results of the new drugs for migraines that will soon be on the market.

Background: Epilepsy is a common neurological disorder in children, associated with significant morbidity and socioeconomic burden. The coronavirus disease 2019 (COVID-19) pandemic disrupted healthcare delivery, potentially exacerbating seizure control among pediatric epilepsy patients. This study aimed to evaluate the pandemic's impact on seizure characteristics and identify risk factors contributing to seizure exacerbation in children with epilepsy. Methods: A retrospective cohort study was conducted using medical records of 84 pediatric epilepsy patients at The Catholic University of Korea Yeouido St. Mary's Hospital from July 2019 to July 2022. Data were collected on demographics, epilepsy characteristics, and healthcare accessibility. Changes in seizure outcomes were analyzed alongside potential risk factors, including infections and socioeconomic variables. Statistical analyses assessed correlations between these factors and seizure exacerbations. Results: Among the 84 pediatric epilepsy patients, 25% experienced significant seizure exacerbations during the COVID-19 pandemic. These included increased seizure frequency (18%), prolonged duration (13%), emergence of new seizure types (4%), and status epilepticus requiring hospitalization (5%). Multivariate analysis identified recent epilepsy diagnosis (<1 year) and low socioeconomic status as independent predictors of seizure worsening (p < 0.05). Infections with non-COVID-19 respiratory viruses, such as RSV and influenza, were strongly associated with exacerbated seizure activity (p < 0.001). Dissatisfaction with access to epilepsy care further increased the risk of poor seizure control, reflecting the challenges posed by disrupted healthcare systems. Notably, no significant relationship was observed between SARS-CoV-2 infection and seizure outcomes, suggesting that indirect factors, rather than direct viral effects, were primary contributors to seizure exacerbation. Conclusions: This study highlights the compounded impact of disrupted healthcare access, socioeconomic challenges, and respiratory viral infections on seizure control during the COVID-19 pandemic. Strategies such as telehealth expansion, regular monitoring, and vaccination against respiratory pathogens are essential to optimize seizure management in future health crises.

Purpose: This study aimed to present clinical and immunological features in patients with neuroimmune complications of COVID-19 during Omicron wave in China. Methods: Patients with neuroimmune complications associated with COVID-19 were retrospectively analyzed in Huashan Hospital from December 2022 to April 2023, during the widespread prevalence of Omicron variants in China. Demographic information, symptoms, electrophysiological findings, cerebrospinal fluid(CSF) test results and immunological markers, Magnetic Resonance Imaging(MRI) characteristics, treatment strategies and outcomes of these patients were reviewed and analyzed. Results: A total of 53 cases of neuroimmune complications were included, with 7 cases of non-immune complications taken as controls. Neuroimmune complications comprised: 7 cases of Guillain-Barre syndrome/chronic inflammatory demyelinating polyneuropathy, 11 cases of spinal meningitis/myelitis, 2 cases of neuromyelitis optica spectrum disorder, 2 cases of myelin oligodendrocyte glycoprotein antibody-associated disease, 1 case of acute disseminated encephalomyelitis, 10 cases of autoimmune encephalitis, 17 cases of other encephalopathy/encephalitis and 3 cases of cerebellitis. SARS-CoV-2 was only detected in the CSF sample of one neuroimmune complications patient. CSF-restricted oligoclonal bands were detected in 11.1% (5/45) of neuroimmune patients, but absent in non-immune cases (0.0%, 0/5). Autoantibody testing identified specific antibodies in 26.5%(13/49) of neuroimmune cases and 0.0% (0/5) of non-immune cases. Glucocorticoids or intravenous immunoglobulins were administered as first-line treatments for all neuroimmune cases (100%, 53/53), whereas only 42.8% (3/7) of non-immune cases received these therapies. A baseline modified Rankin scale (mRS) score of 3 or above was present in the majority of both neuroimmune cases (96.2%, 51/53) and non-immune cases (71.4%, 5/7). At the end of a follow-up period, independent functional outcomes at day-90 with an mRS score below two were observed in a significant proportion of both neuroimmune cases (77.4%, 41/53) and non-immune case(71.4%, 5/7). Conclusion: The manifestations of neuroimmune complications of COVID-19 are diverse and can manifest with severe neurological deficits early in the course of the disease. The detection of immunological markers (such as autoantibody and oligoclonal bands) and immunotherapies can help to improve the prognosis of COVID-19 related neuroimmune complications.

Background: Neurological complications are a significant concern of Coronavirus Disease 2019 (COVID-19). However, the pathogenic mechanism of neurological symptoms associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is poorly understood. Methods: We used Drosophila as a model to systematically analyze SARS-CoV-2 genes encoding structural and accessory proteins and identified the membrane protein (M) that disrupted mitochondrial functions in vivo. The M protein was stereotaxically injected to further assess its effects in the brains of wild-type (WT) and 5 × FAD mice. Omics technologies, including RNA sequencing and interactome analysis, were performed to explore the mechanisms of the effects of M protein both in vitro and in vivo. Results: Systematic analysis of SARS-CoV-2 structural and accessory proteins in Drosophila identified that the M protein induces mitochondrial fragmentation and dysfunction, leading to reduced ATP production, ROS overproduction, and eventually cell death in the indirect flight muscles. In WT mice, M caused hippocampal atrophy, neural apoptosis, glial activation, and mitochondrial damage. These changes were further aggravated in 5 × FAD mice. M was localized to the Golgi apparatus and genetically interacted with four wheel drive (FWD, a Drosophila homolog of mammalian PI4KIIIβ) to regulate Golgi functions in flies. Fwd RNAi, but not PI4KIIIα RNAi, reversed the M-induced Golgi abnormality, mitochondrial fragmentation, and ATP reduction. Inhibition of PI4KIIIβ activity suppressed the M-induced neuronal cell death. Therefore, M induced mitochondrial fragmentation and apoptosis likely through disruption of Golgi-derived PI(4)P-containing vesicles. Conclusions: M disturbs the distribution and function of Golgi, leading to mitochondrial abnormality and eventually neurodegeneration via a PI4KIIIβ-mediated mechanism. This study reveals a potential mechanism for COVID-19 neurological symptoms and opens a new avenue for development of therapeutic strategies targeting SARS-CoV-2 M or mitochondria.

To systematically examine the literature on the clinical consequences of inadvertent delays in scheduled onabotulinumtoxin A (OTA) therapy for chronic migraine during the COVID-19 pandemic and assess recommendations when access to OTA is limited. Background: The coronavirus (COVID-19) pandemic was unprecedented in its impact on the global medical community. Most healthcare institutions in the United States (US) and the world had begun significantly limiting elective procedures, undermining management of many debilitating chronic conditions. OTA injections, were similarly involuntarily postponed, leading to significant setbacks in symptom control. Methods: A comprehensive literature search was conducted on databases of Medline and Embase with search timeframe defined as the point of database inception to March 1st, 2024, and the search was performed on March 2nd, 2024. The search strategy was independently formulated by two authors (QR and CR) and was reviewed and approved by all authors of the article after appropriate amendments. Results: A total of nine articles met the defined inclusion criteria. They collectively demonstrated marked delays in OTA treatment with decline in migraine symptom control measured in the form of migraine intensity, frequency, as well as patient satisfaction in disease management. Quality of care in the form of follow-ups also appeared compromised. Alternative strategies of telemedicine and the administration of calcitonin gene-related peptide monoclonal antibodies (CGRP mAb) were adopted in place of conventional treatment. Conclusion: The COVID-19 pandemic had caused marked clinical deterioration in the migraine patient populations across US, Europe, and the Middle East. Strategies employed to circumvent this limitation included the adoption of remote consultation via telemedicine as well as the use of pharmacological agents such as CGRP antagonists. In the event of a reoccurrence of a worldwide pandemic, strategies should be implemented to prevent the cessation of needed treatment for those suffering from chronic migraine.

The COVID-19 outbreak, caused by the SARS-CoV-2 virus, was linked to significant neurological and psychiatric manifestations. This review examines the physiopathological mechanisms underlying these neuropsychiatric outcomes and discusses current management strategies. Primarily a respiratory disease, COVID-19 frequently leads to neurological issues, including cephalalgia and migraines, loss of sensory perception, cerebrovascular accidents, and neurological impairment such as encephalopathy. Lasting neuropsychological effects have also been recorded in individuals following SARS-CoV-2 infection. These include anxiety, depression, and cognitive dysfunction, suggesting a lasting impact on mental health. The neuroinvasive potential of the virus, inflammatory responses, and the role of angiotensin-converting enzyme 2 (ACE2) in neuroinflammation are critical factors in neuropsychiatric COVID-19 manifestations. In addition, the review highlights the importance of monitoring biomarkers to assess Central Nervous System (CNS) involvement. Management strategies for these neuropsychiatric conditions include supportive therapy, antiepileptic drugs, antithrombotic therapy, and psychotropic drugs, emphasizing the need for a multidisciplinary approach. Understanding the long-term neuropsychiatric implications of COVID-19 is essential for developing effective treatment protocols and improving patient outcomes. [ABSTRACT FROM AUTHOR]

Aim of study. This study aimed to compare headache and facial pain prevalence and headache phenotype among people with common upper respiratory tract infections (URTIs). Clinical rationale for study. Headache is a common symptom in viral URTI, but its phenotyping has so far been limited to coronavirus disease 2019 (COVID-19) and influenza. Additionally, the prevalence of facial pain in URTIs has only rarely been discussed in scientific publications. Material and methods. Patients with acute URTI symptoms were evaluated for headache phenotype using a semi-structured questionnaire. Antigen swab tests were performed in all participants. Results. The analysis included 276 URTI/APVRS (acute post-viral rhinosinusitis) episodes in 223 patients (136 women, 60.1%) aged 18-73 [mean 41.3 / median (25th, 75th) 40 / standard deviation 15.1]. Participants were diagnosed with: COVID-19 -- 107/276 (38.8%); 'common cold' -- 103/276 (37.3%); influenza -- 36/276 (13.0%); or APVRS -- 30/276 (10.9%). Headache was present in 183/276 (66.3%) and URTIs and facial pain in 107/276 (38.8%). Predictors of headache in URTIs included sinonasal symptoms (odds ratio (OR) 10.70, p < 0.001) and fever (OR 2.9, p = 0.004). Headache more often (p = 0.030) had a migraine-like phenotype in COVID-19 (27.4% (20/73) vs. 9.1% (10/110) and tension-type headache (TTH)-like phenotype in 'common cold' (75.4%, 49/64 vs. 61.3%, 73/119). Previous COVID-19 immunisation (vaccination or infection) was associated (p = 0.004) with a lower prevalence of migraine-like headache [6.3% (1/16) vs. 32.8% (19/58)]. Conclusions and clinical implications. Headache and facial pain are prevalent during URTIs, and are associated with general and sinonasal immune response rather than virus type. Headache phenotype may depend on the causative microorganism, but it can evolve in response to previous immunisation. Our study supports vaccination against COVID-19, as people with prior immunisation are probably less likely to experience migraine-like headache. [ABSTRACT FROM AUTHOR]

Background: Evidence for the pathogenesis and treatment of postacute coronavirus disease 2019 (COVID‐19) (long COVID) is lacking. As long COVID symptoms are predicted to have an impact on the global economy, clarification of the pathogenesis is urgently needed. Our experiences indicated that some symptoms were complicated by diseases established before the COVID‐19 pandemic. Methods: Using a retrospective, cross‐sectional study, we aimed to evaluate the diseases complicating long COVID. Using the medical records of patients with confirmed COVID‐19 exhibiting residual symptoms lasting ≥60 days postinfection who visited our clinic in January 2021–February 2023, we investigated the symptoms and diseases observed. We identified diseases that occurred after COVID‐19 and excluded those that were exacerbations of existing diseases. Results: During the first visit, the most common symptoms reported in a total of 798 patients were fatigue (523 patients), anxiety (349 patients), and lack of motivation (344 patients). Complicating diseases were observed in 452 patients (57%). There were 115, 65, and 60 patients with postural tachycardia syndrome, postural syndrome without tachycardia, and mood disorders, respectively. Some diseases requiring immediate treatment included pulmonary thromboembolism, purulent shoulder arthritis, cerebellopontine angle tumors, myasthenia gravis, and cervical myelopathy. Conclusion: Not all symptoms that occur after COVID‐19 should be treated as long COVID. Similar to normal medical treatment, a list of differential diagnoses should be maintained based on symptoms to obtain definitive diagnoses. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic represents a global health phenomenon that will sadly remain part of our history. It had innumerable consequences for society and people's lives. With different mechanisms, COVID-19 has been pointed out as a factor in the pathophysiology of several secondary disorders or the deterioration of pre-existing conditions. Migraine is a frequent disorder that can be influenced by several conditions, including psychologically stressful conditions or infectious diseases. The purpose of the present study is to gain insight into the influence of COVID-19 on the clinical characteristics of patients with migraine. A self-administrable questionnaire has been developed, asking for migraine features before and after COVID-19 infection. One hundred and two patients who had been infected at least once were included. After COVID-19 infection, 54 reported the worsening of migraine, 45 noticed no variation, and 3 reported an improvement. After the infection, 21 patients changed preventive therapy due to the loss of efficacy of the previous one. The most effective treatments in this subpopulation were gene-related peptide monoclonal antibodies. The presented data confirm that the influence of COVID-19 is heterogeneous in patients with migraine, but new treatments may be effective in controlling the symptoms among those who report a worsening of the disease.

Objectives: Existing data regarding the risk of COVID‐19 infection and its effects on seizure control in patients with epilepsy (PWE) are inconclusive. Our research aims to investigate the PWE who are susceptible to COVID‐19 and what factors contribute to seizure exacerbation. Methods: From Dec 28, 2022 to Feb 19, 2023, a cross‐sectional questionnaire survey among adult PWE was conducted. The demographics, epilepsy‐related information, COVID‐19‐related variables, and seizure outcomes after COVID‐19 infection were collected. Multivariate logistic analyses were performed to determine the risk factors associated with COVID‐19 infection and exacerbated seizures. Results: Of 1557 PWE, 829 (53.2%) were infected with COVID‐19 and 136 (16.4%) developed seizure exacerbation after COVID‐19 infection. Overweight/obesity (OR 1.372, 95% CI 1.075–1.753, p = 0.011), immunocompromised (OR 3.301, 95% CI 1.093–9.974, p = 0.031), active epilepsy (OR 1.700, 95% CI 1.378–2.097, p < 0.001), and antiseizure medication (ASM) polytherapy (OR 1.314, 95% CI 1.065–1.621, p = 0.011) were associated with COVID‐19 infection. Active epilepsy (OR 4.696, 95% CI 2.568–8.586, p < 0.001) and fever‐associated seizures (OR 4.298, 95%CI 2.659–6.946, p < 0.001) were associated with seizure exacerbation. Significance: PWE with overweight/obesity, immunocompromised, active epilepsy, and ASM polytherapy were at higher risk of COVID‐19 infection. Once infected with COVID‐19, seizures were exacerbated in PWE with active epilepsy and fever‐associated seizures. Plain language summary: Patients with epilepsy (PWE) do not appear to be more susceptible to COVID‐19 infection than general population. Once infected with COVID‐19, 16.4% of PWE had seizure exacerbation. The PWE who have experienced seizures within the past 12 months before infection tend to contract COVID‐19 more often, and are more likely to experience seizure exacerbations following COVID‐19 infection.

Polymyositis is a rarely reported complication of COVID-19 illness, especially in children. Molecular mimicry may be a cause of hyperactivated autoimmunity, leading to various clinical manifestations, including myopathies. Symptoms vary from mild muscle weakness to severe rhabdomyolysis. We review the literature on post-COVID myositis and report a case of severe polymyositis in a 7-year-old boy, following undefined viral infection 3 weeks before the onset of muscle pain. Patient's condition deteriorated from physical activity-associated pain in the lower limbs to severe muscle weakness leading to dysphagia and mechanical ventilation. As antibodies against SARS-CoV-2 were detected and other possible conditions causing myositis were excluded, the diagnosis of post-COVID polymyositis was considered as the most likely. The patient was treated with high doses of methylprednisolone and cyclophosphamide, resulting in improvement. Although COVID-19 is becoming a seasonal disease, the infection itself and post-viral disorders, such as polymyositis, are still of great interest and require better investigation to ensure appropriate management for each individual. Our experience suggests that aggressive immunosuppressive therapy might be a solution for severe post-COVID-related diseases. This literature review is provided in addition to the case report presented at the 29th European Paediatric Rheumatology Congress; the abstract is available online in the Proceedings of the 29th European Paediatric Rheumatology Congress.

Due to the abundance of ACE2 receptors in nervous system cells, the SARS-CoV-2 virus can cause damage to this system. This study aims to examine the prevalence of neurological symptoms in COVID-19 patients. In this cross-sectional observational study, 75 COVID-19 positive patients admitted to Golestan Hospital’s neurology department in Ahvaz, Iran, from March 2020 to March 2023, were investigated. Neurological clinical symptoms were categorized into three groups: central nervous system, peripheral, and muscular symptoms. The relevant information was collected from patient files, including medical history, imaging data, and laboratory test results. Statistical analysis was performed using SPSS software, employing the rank-biserial correlation coefficient (r), Mann–Whitney U tests, Phi correlation, Cramer’s V, and Kendall’s Tau to evaluate the prevalence and significance of neurological symptoms. The most common clinical symptoms observed were hemiparesis, dysarthria, Central Facial Palsy (CFP), ataxia, and nausea, respectively. Among these symptoms, headaches (p = 0.001), seizures (p = 0.024), and nausea (p = 0.046) were found to be more prevalent in younger patients. Additionally, a significant relationship was identified between the level of serum Creatine phosphokinase (CPK) and seizures (p = 0.024), with lower levels observed in individuals with vomiting (p = 0.024), and higher levels observed in individuals with CFP (p = 0.040). This study highlights that patients with COVID-19 may experience serious neurological symptoms. The clinical spectrum and range of neurological symptoms associated with COVID-19 were found to be diverse and extensive, emphasizing the importance of considering this infection as a potential cause of neurological disorders.

To describe the need and effectiveness of acute and preventive medications in a series of 100 consecutive patients referred due to COVID-19-related headaches. Patients were aged 48.0 (standard deviation (SD): 12.4), 84% were female, and 56% had a prior history of headache. The most common headache phenotype was holocranial (63%), frontal (48%), pressing (75%), of moderate intensity (7 out of 10), and accompanied by photophobia (58%). Acute medication was required by 93%, with paracetamol (46%) being the most frequently used drug, followed by ibuprofen (44%). The drugs with the highest proportion of a 2 h pain-freedom response were dexketoprofen (58.8%), triptans (57.7%), and ibuprofen (54.3%). Preventive treatment was required by 75% of patients. The most frequently used drugs were amitriptyline (66%), anesthetic blockades (18%), and onabotulinumtoxinA (11%). The drugs with the highest 50% responder rate were amitriptyline (45.5%), mirtazapine (50%), and anesthetic blockades (38.9%). The highest 75% responder rate was experienced following onabotulinumtoxinA (18.2%). In conclusion, most patients required acute medication, with triptans and non-steroidal anti-inflammatory drugs achieving the best responses. Three-quarters of patients required preventive medication. The most frequently used drug was amitriptyline, which obtained the best results. In some treatment-resistant patients, anesthetic blockades and onabotulinumtoxinA were also beneficial. [ABSTRACT FROM AUTHOR]

FOLFOX is a widely used regimen in the management of gastrointestinal malignancies and is a combination of 5-fluorouracil (5-FU), folinic acid, and oxaliplatin. Raltitrexed is an antifolate thymidylate synthase inhibitor which is used as an alternative when 5-FU is not tolerated. Here we present a case of interstitial lung disease as a rare side-effect of oxaliplatin and raltitrexed. Not much is known about the pathophysiology of the condition and most information available in the literature is taken from published case reports. [ABSTRACT FROM AUTHOR]

Background: Little is known about the frequency and impact of the persistent headache and about the incidence of chronic daily headache (CDH) after coronavirus disease 2019 (COVID-19). The aim of this prospective cohort study was to assess the incidence, risk factors, characteristics, and impact of CDH in patients with COVID-19. Methods: In the first stage, 288 patients were interviewed by telephone after the acute phase of COVID-19. Subsequently, 199 patients who presented headache were reinterviewed at least one year after COVID-19. Headaches that persisted beyond the acute phase of COVID-19 for three or more months and presented frequency ≥ 45 days over the first three months were considered to be CDH. Results: One hundred and twenty-three patients were included, 56% were females; median age: 50 years (25th and 75th percentile: 41;58). The headache persisted beyond the acute phase of COVID-19 in 52%, and 20.3% had CDH (95% confidence interval: 13.6--28.2). Individuals who previously had headaches and who had headaches of greater intensity during the acute phase were at higher risk of developing CDH. The group with CDH included more females, greater impact of headache, more persistence of headache beyond the 120th day of COVID-19 and less throbbing headache than did the other individuals whose headache persisted. Conclusions: Patients who had COVID-19 had a high incidence of CDH. Previous headache and greater intensity of headache were associated with higher risk of CDH. [ABSTRACT FROM AUTHOR]

Background: New onset or worsening of a headache disorder substantially contributes to the disease burden of post-COVID-19. Its management poses a suitable means to enhance patients' participation in professional, social, and personal activities. Unfortunately, the pathophysiology of post-COVID-19 headaches is poorly understood. This study aims to investigate the role of (neuro-) inflammatory mechanisms in order to guide the development of anti-inflammatory treatment strategies. Methods: We included patients from the interdisciplinary post-COVID-19 Rehabilitation Study (PoCoRe, n = 184 patients) run at a tertiary care university hospital, comprising patients with PCR-confirmed SARS-CoV-2 infection ≥ 6 weeks prior to their initial consultation. Patients reporting any headache since their infection were considered for this study (n = 93). These were interviewed and classified according to the International Classification of Headache Disorders, Third Edition (ICHD-3) by headache specialists. Patient sera were additionally analysed for levels of VILIP-1, MCP-1 (CCL2), sTREM-2, BDNF, TGF-ß1, VEGF, IL-6, sTREM-1, ß-NGF, IL-18, TNF-alpha, sRAGE, and CX3CL1 (Fractalkine). Markers of inflammation were compared between four groups of patients (none, unchanged, worsened, or new headache disorder). Results: Patients reported experiencing more severe headaches (n = 17), new onset headaches (n = 46), unchanged headaches (n = 18), and surprisingly, some patients denied having any headaches (n = 12) despite self-reports. Serum levels of CX3CL1 were increased in the worsened (2145 [811–4866] pg/ml) and new onset (1668 [0-7357] pg/ml) headache group as compared to patients with no (1129 [0-5379] pg/ml) or unchanged (1478 [346–4332] pg/ml) headaches. Other markers also differed between groups, but most significantly between patients with worsened (TGF-ß1: 60 [0-310] pg/ml, VEGF: 328 [86–842] pg/ml, ß-NGF: 6 [3–38] pg/ml) as compared to unchanged headaches (TGF-ß1: 29 [0–77] pg/ml, VEGF: 183 [72–380] pg/ml, ß-NGF: 3 [2–89] pg/ml). The results did not differ between headache phenotypes. Discussion: This study provides evidence that worsened or new headaches following COVID-19 are associated with pro-(neuro-)inflammatory profiles. This supports the use of anti-inflammatory treatment options in this population, especially in the subacute phase. [ABSTRACT FROM AUTHOR]

COVID-19, a respiratory illness with a global impact on millions, has recently been linked to manifestations affecting various bodily systems, including the oral cavity. Studies highlight oral issues, like ulcers, blisters, and white patches, alongside olfactory and gustatory dysfunction, influencing an individual's quality of life. In this context, our study aimed to assess the frequency of oral lesions, olfactory and gustatory disorders, and xerostomia resulting from COVID-19. An observational study was conducted with 414 patients to evaluate the frequency of oral symptoms resulting from COVID-19. Patients were diagnosed with mild symptoms and evaluated through clinical examination of the oral cavity and a questionnaire to assess functional alterations. The findings showed that 139 out of 414 patients presented clinical manifestations, with oral lesions being the most prevalent (19.1%), followed by gustatory disorders (18.1%), xerostomia (14.2%), and olfactory dysfunction (14%). The most prevalent oral lesions were ulcerations (n = 51), candidiasis (n = 8), and erythema or red plaques (n = 7). Unfortunately, 50 (12.1%) patients died during this study. Therefore, oral lesions, olfactory and gustatory dysfunctions, and xerostomia are common symptoms associated with COVID-19. [ABSTRACT FROM AUTHOR]

Objective: To characterize the cognitive profile of long COVID-19 subjects and its possible association with clinical symptoms, emotional disturbance, biomarkers, and disease severity. Methods: We performed a single-center cross-sectional cohort study. Subjects between 20 and 60 years old with confirmed COVID-19 infection were included. The assessment was performed 6 months following hospital or ambulatory discharge. Excluded were those with prior neurocognitive impairment and severe neurological/neuropsychiatric disorders. Demographic and laboratory data were extracted from medical records. Results: Altogether, 108 participants were included, 64 were male (59.25%), and the mean age was 49.10 years. The patients were classified into four groups: non-hospitalized (NH, n = 10), hospitalized without Intensive Care Unit (ICU) or oxygen therapy (HOSPI, n = 21), hospitalized without ICU but with oxygen therapy (OXY, n = 56), and ICU (ICU, n = 21) patients. In total, 38 (35.18%) reported Subjective Cognitive Complaints (SCC). No differences were found considering illness severity between groups. Females had more persistent clinical symptoms and SCC than males. Persistent dyspnea and headache were associated with higher scores in anxiety and depression. Persistent fatigue, anxiety, and depression were associated with worse overall cognition. Conclusions: No cognitive impairment was found regarding the severity of post-COVID-19 infection. SCC was not associated with a worse cognitive performance, but with higher anxiety and depression. Persistent clinical symptoms were frequent independent of illness severity. Fatigue, anxiety, and depression were linked to poorer cognitive function. Tests for attention, processing speed, and executive function were the most sensitive in detecting cognitive changes in these patients. [ABSTRACT FROM AUTHOR]

Background: The prolonged psychiatric disorders rate following coronavirus disease 2019 (COVID-19) could surpass that of severe acute respiratory syndrome (SARS) as well as Middle East Respiratory Syndrome (MERS) as a result of variations in viral disease treatment as well as societal circumstances throughout the outbreaks. This work aimed to investigate the COVID-19 prolonged psychiatric effects on survivors without psychiatric diseases before infection. Methods: This cross-sectional research was conducted on 1254 patients of which 700 patients (55.8%) were positive for psychiatric complications based on the general health (GHQ-28) questionnaire and 554 patients (44.1%) were negative, aged above 18 years old who had been infected with COVID19 (PCR swab confirmed) and recovered since less than 6 months without previous history of any psychiatric disease. Results: Smoking, medical comorbidities, hospitalization, and cortisone in treatment were significantly higher in GHQ-28 positive than GHQ-28 negative (p < 0.05). Psychiatric disorders and Beck's Depression Inventory (BDI) grades showed a significant association between smoking and hospitalization and Taylor Manifest Anxiety scales and smoking, hospitalization, and treatment with cortisone). Smoking, medical comorbidities, hospitalization, and cortisone in treatment were the most significant predictors of positive GHQ-28. However, multivariate analysis demonstrated that medical comorbidities, hospitalization, and cortisone in treatment were the best independent predictors of GHQ-28 positive (p = 7.055, p = 0.007, p = 0.043, p = 0.047, respectively). Conclusions: COVID-19 cases without pre-existing psychological disorders exhibited a significant increase in psychiatric disorders occurrence 6 months following recovery. Anxiety disorders represented the predominant mental diagnoses documented. [ABSTRACT FROM AUTHOR]

Introduction: The emergence of the coronavirus in 2019 became a global epidemic disease. According to the World Health Organization, people with a history of chronic diseases such as brain stroke are among the main groups at risk of contracting COVID‑19. Therefore, this study was performed with the aim of the determination amount of the frequency of contracting COVID‑19 in stroke patients. Materials and Methods: This descriptive‑analytical study was conducted on 100 patients with a history of stroke referred to Imam Hossein Hospital in Tehran (Iran) between 2019 and 2022, which had all the inclusion criteria in the study. The demographic information including (gender, weight, height) and clinical information was collected by a researcher‑made questionnaire and analyzed by SPSS version 24 software. Results: The average age of the studied patients was 63 years. Among them, 53 people (53%) were infected with COVID‑19. The most of underlying diseases were related to high blood pressure. All cases of stroke in patients with COVID‑19 were associated with thrombotic type, and half of the other cases included involvement in large cerebral vessels. Lymphocyte count, CRP, and ESR levels were relatively higher in stroke patients with COVID‑19, but there were observed no cases of pleural effusion and pericardial effusion associated with COVID‑19 in stroke patients. In all of the patients with COVID‑19, pulmonary involvement was observed in the Peripheral/Perihillar area. Discussion and Conclusion: According to the results and data of this research, the probability of infecting COVID‑19 is higher in people with a history of stroke, and these patients have more severe strokes and more mortality than stroke patients without contracting COVID‑19.

Background: Migraine is a leading cause of disability, estimated to affect one-in-ten people in Spain. This study aimed to describe the management of migraine in Spain and identify improvement areas. Methods: Non-interventional, retrospective, cross-sectional cohort study conducted using an electronic medical records database covering visits to public healthcare providers for 3% of the Spanish population. Patients with a migraine diagnosis (ICD-9 346) between 01/2015 and 04/2022 were included, as well as their demographic and clinical characteristics, prescribed migraine treatments and the specialty of the prescribing physicians. Results: The database included 61,204 patients diagnosed with migraine. A migraine treatment had been prescribed to 50.6% of patients over the last 24 months (only acute to 69.5%, both acute and preventive to 24.2%, and only preventive to 6.3%). The most frequently prescribed treatments were NSAIDs (56.3%), triptans (44.1%) and analgesics (28.9%). Antidepressants were the most common preventive treatment (prescribed to 17.9% of all treated patients and 58.7% of those treated with a preventive medication), and anti-CGRP monoclonal antibodies the least prescribed (1.7%; 5.7%). In 13.4% of cases, preventive medications were the first treatment: alone in 5.8% of cases and together with an acute medication in 7.6%. A fifth of patients who were initially prescribed with only acute treatment were later prescribed a preventive medication (20.7%). On average, it took 29.4 months for this change to occur. Two-thirds of patients started their preventive treatment in primary care (64.2%). The percentage of patients treated by a neurologist increased with the number of received preventive medications. However, 28.8% of patients who had already been prescribed five or more distinct preventive treatments were not treated by a neurologist. Migraine patients had between 1.2- and 2.2-times higher prevalence of comorbidities than the general population, age-gender adjusted. Conclusions: Our study emphasizes the need for improved management of migraine in Spain to reduce the risk of chronification and improve patient outcomes. More training and coordination across healthcare professionals is necessary to recognize and address risk factors for migraine progression, including multiple associated comorbidities and several lines of treatment, and to provide personalized treatment plans that address the complex nature of the condition.

Background: The COVID-19 pandemic has been associated with multiple psychiatric problems in the general population as well as in those admitted with the infection. Studies done so far have mainly focused on the general population. It is important to address the needs and gaps in mental and psychological aspect of health of patients admitted with the infection to improve their overall prognosis. This study was undertaken with the aim to study the pattern of psychiatric referrals of hospitalized COVID-19 patients and to find out if there is any association between their socio-demographics, severity of COVID-19 infection, inflammatory markers, and co-morbidities. Materials and Methods: A descriptive, retrospective chart analysis of the record of 160 psychiatry referrals for COVID-19 patients seen by the on-call psychiatrist from May 2020 to October 2020 in a tertiary care hospital was undertaken. Sociodemographic data, severity of COVID-19 infection, blood investigation reports, psychiatric symptoms, diagnosis and management were recorded, tabulated, and analyzed using SPSS 20. Results: Referrals were more for individuals having moderate-to-severe COVID-19 infection, in elderly patients and in males. The most common reason for referral was disorientation (27.5%) and insomnia (27.5%), followed by the patient having a preexisting psychiatric illness (15%). The most common psychiatric diagnosis was delirium secondary to general medical condition, (28%), followed by anxiety and depressive spectrum disorders (23.75%). 32.5% of the patients referred had a past history of psychiatric illness, the most common being substance use disorder, followed by major depressive disorder and mixed anxiety depression. With the increase in the age of the individuals, the number of referrals for males was significantly more as compared to females (P = 0.00). No statistically significant association was found between age (P = 0.83), gender (P = 0.99), and psychiatric diagnosis. No significant association was found between the severity of COVID-19 and psychiatric diagnosis (P = 0.69). Conclusion: It is essential to screen for psychiatric disorders in patients admitted for COVID, as it goes a long way in reducing the overall morbidity and improves patient cooperation for various procedures which could be life-saving.

Background: Accumulating evidence on the neurological sequelae of COVID-19 is a serious concern, with patients possibly being at risk of permanent debilitation if not managed appropriately. We aimed to determine the prevalence and pattern of neurological manifestations and diagnostic and therapeutic findings among hospitalized COVID-19 patients consulted with the neurology service for neurological disorders. We conducted a retrospective, observational study at the Golestan Hospital of Ahvaz, Iran, between March 20, 2020, and March 19, 2021. Patients' demographic, clinical, paraclinical, and therapeutic characteristics were extracted from medical records and then subjected to statistical analysis. Results: Overall, 6.7% (157/2340) of COVID-19 patients at Golestan Hospital had a neurological disorder. Most of the patients (90/157) were men, and the mean age of patients was 62.91 ± 91 years. A total of 56.68% of patients (89/157) were SARS-CoV-2 RT-PCR positive. The mean chest CT severity score was 8.26 ± 4.4, ranging from 1 to 19. The most common neurologic disorders were cerebrovascular disease (72.6%), encephalopathy (8.9%), and Guillain–Barre syndrome (6.4%). The CSF SARS-CoV-2 PCR test was positive in one patient with Guillain–Barre syndrome. The in-hospital mortality rate was 43.9%. Definite COVID-19, ICU admission, history of stroke and dementia, and comorbidities were associated with an increased mortality risk in these patients. Conclusions: Patients with COVID-19 can present with serious neurological disorders such as cerebrovascular disease and impaired consciousness, even without typical COVID-19 symptoms. Close monitoring for neurological symptoms may help improve prognosis in hospitalized COVID-19 patients. [ABSTRACT FROM AUTHOR]

The World Health Organization reports that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has impacted a staggering 770 million individuals to date. Despite the widespread nature of this viral infection, its precise effects remain largely elusive. This scientific inquiry aims to shed light on the intricate interplay between SARS-CoV-2 infection and the development of neurodegenerative disorders—an affliction that weighs heavily on millions worldwide and stands as the fourth most prevalent cause of mortality. By comprehensively understanding the repercussions of SARS-CoV-2 on neurodegenerative disorders, we strive to unravel critical insights that can potentially shape our approach to the diagnosis, prevention, and treatment of these debilitating conditions. To achieve this goal, we conducted a comprehensive literature review of the scientific data available to date showing that SARS-CoV-2 infection is associated with increased risk and severity of neurodegenerative disorders, as well as altered expression of key genes and pathways involved in their pathogenesis.

"Long COVID" is a term used to describe a condition when the symptoms and signs associated with coronavirus disease 2019 (COVID-19) persist for more than three months among patients infected with COVID-19; this condition has been reported globally and poses a serious public health issue. Long COVID can manifest in various forms, highlighting the need for appropriate evaluation and management by experts from various fields. However, due to the lack of clear clinical definitions, knowledge of pathophysiology, diagnostic methods, and treatment protocols, it is necessary to develop the best standard clinical guidelines based on the scientific evidence reported to date. We developed this clinical guideline for diagnosing and treating long COVID by analyzing the latest research data collected from the start of the COVID-19 pandemic until June 2023, along with the consensus of expert opinions. This guideline provides recommendations for diagnosis and treatment that can be applied in clinical practice, based on a total of 32 key questions related to patients with long COVID. The evaluation of patients with long COVID should be comprehensive, including medical history, physical examination, blood tests, imaging studies, and functional tests. To reduce the risk of developing long COVID, vaccination and antiviral treatment during the acute phase are recommended. This guideline will be revised when there is a reasonable need for updates based on the availability of new knowledge on the diagnosis and treatment of long COVID. [ABSTRACT FROM AUTHOR]

Introduction: The Coronavirus Disease-2019 (COVID-19) pandemic, which started in December 2019, has rapidly spread across the globe. Although the prevalence of COVID-19 disease has significantly decreased, there are cases of post-COVID-19 complications affecting multiple organ systems, including the eyes. Aim: To evaluate ocular diseases presenting in post-COVID-19 patients and their association with demographic profiles, duration of post-COVID-19, and the type of treatment received. Materials and Methods: A descriptive cross-sectional study was conducted over a four-month period (August 2021 to November 2021) in the Department of Ophthalmology at AIIMS, Mangalagiri, Guntur, Andhra Pradesh, India. The study focused on post-COVID-19 patients who had been affected by COVID-19 no more than three months prior. Patients who were not post-COVID-19 and those who had contracted COVID-19 during the first wave were excluded from the study. The patients' clinical history and symptoms were documented. Visual acuity, intraocular pressure, and detailed anterior and posterior segment findings were recorded for all patients. The study aimed to assess post-COVID-19 ocular complications and any potential associations with hospital stays, steroid intake, or oxygen inhalation on eye diseases. Mean and median calculations were performed for continuous variables, and a Chi-square test was used to study associations. Statistical Package for Social Sciences (SPSS) version 25.0 was employed, and a p-value <0.05 was deemed significant. Results: In the present study, males constituted 41 (62.1%) and females constituted 25 (37.9%), with a male-to-female ratio of 1.64:1. The majority of patients 23 (34.8%) were above 50 years old. Most patients 24 (36.4%) developed eye diseases one month after their COVID-19 infection. Out of 66 patients, 11 (16.7%) were diabetic, 8 (12.1%) were hypertensive, and 40 (60.6%) had no associated co-morbidities. During their COVID-19 illness, 53 (80.3%) patients underwent home isolation and received supportive treatment, while 13 (19.7%) patients were hospitalised. The most common ocular disease observed was conjunctivitis 39 (59.1% of patients) following post-COVID-19. Additionally, 4 (6%) patients developed central serous chorioretinopathy, 4 (6%) developed refractive errors, 5 (7.6%) experienced persistent headaches, and 2 (3%) developed orbital mucormycosis. Conclusion: The present study presents ophthalmic manifestations in post-COVID-19 patients. Conjunctivitis was found to be the most common ocular disease, more prevalent one month after the COVID-19 infection. COVID-19 retinopathy was the most common posterior segment complication, especially in patients above 50 years old and three months post-COVID-19. [ABSTRACT FROM AUTHOR]

Current definitions of migraine that are based mainly on clinical characteristics do not account for other patient's features such as those related to an impaired quality of life, due to loss of social life and productivity, and the differences related to the geographical distribution of the disease and cultural misconceptions which tend to underestimate migraine as a psychosocial rather than neurobiological disorder. Global differences definition, care access, and health equity for headache disorders, especially migraine are reported in this paper from a collaborative group of the editorial board members of the Journal of Headache and Pain. Other components that affect patients with migraine, in addition to the impact promoted by the migraine symptoms such as stigma and social determinants, are also reported. [ABSTRACT FROM AUTHOR]

Background: Headache is one of the most common symptoms of acute COVID-19 infection. However, its mechanisms remain poorly understood, and there is a lack of studies investigating changes in the periaqueductal gray (PAG) in COVID-19 patients exhibiting headaches. Purpose: The study aimed to explore the alterations in metabolites of the PAG pre- and post-COVID-19 infection in individuals who suffered from headaches during the acute phase of the disease using proton magnetic resonance spectroscopy (1H-MRS). Methods: Fifteen participants who experienced headaches during the acute phase of COVID-19 were recruited. All subjects underwent two proton magnetic resonance spectroscopy (1H-MRS) examinations focusing on the PAG before and after they were infected. Metabolite changes were assessed between the pre- and post-infection groups. Results: The combined glutamine and glutamate/total creatine ratio (Glx/tCr) was increased in the PAG following COVID-19 infection. The total choline/total creatine ratio (tCho/tCr) in the pre-infection group was negatively correlated with the duration of headache during the COVID-19 acute phase. Conclusion: The present study indicates that PAG plays a pivotal role in COVID-19 headaches, thereby supporting the involvement of trigeminovascular system activation in the pathophysiology of COVID-19 headaches.

COVID-19 is primarily a respiratory disease, but numerous studies have indicated the involvement of various organ systems during the course of illness. We conducted a comprehensive review of atypical complications of COVID-19 with their incidence range (IR) and their impact on hospitalization and mortality rates. We identified 97 studies, including 55 research articles and 42 case studies. We reviewed four major body organ systems for various types of atypical complications: (i) Gastro-intestinal (GI) and hepatobiliary system, e.g., bowel ischemia/infarction (IR: 1.49–83.87%), GI bleeding/hemorrhage (IR: 0.47–10.6%), hepatic ischemia (IR: 1.0–7.4%); (ii) Neurological system, e.g., acute ischemic stroke/cerebral venous sinus thrombosis/cerebral hemorrhage (IR: 0.5–90.9%), anosmia (IR: 4.9–79.6%), dysgeusia (IR: 2.8–83.38%), encephalopathy/encephalitis with or without fever and hypoxia (IR: 0.19–35.2%); (iii) Renal system, e.g., acute kidney injury (AKI)/acute renal failure (IR: 0.5–68.8%); (iv) Cardiovascular system, e.g., acute cardiac injury/non-coronary myocardial injury (IR: 7.2–55.56%), arrhythmia/ventricular tachycardia/ventricular fibrillation (IR: 5.9–16.7%), and coagulopathy/venous thromboembolism (IR: 19–34.4%). This review encourages and informs healthcare practitioners to keenly monitor COVID-19 survivors for these atypical complications in all major organ systems and not only treat the respiratory symptoms of patients. Post-COVID effects should be monitored, and follow-up of patients should be performed on a regular basis to check for long-term complications. [ABSTRACT FROM AUTHOR]

Objective: To assess the incidence, characteristics, and risk factors for developing persistent headache attributed to past ischemic stroke. Background: Although the most recent International Classification of Headache Disorders has recognized the existence of persistent headache attributed to past ischemic stroke, there has been limited research in this area. Methods: This was a prospective cohort study. We initially assessed patients hospitalized with ischemic stroke admitted within 72 h of symptom onset. All patients underwent diffusion‐weighted magnetic resonance imaging. These patients were re‐interviewed by telephone 1 year after the stroke. Semi‐structured questionnaires, the National Institutes of Health Stroke Scale (NIHSS), and six‐item Headache Impact Test were used. Results: A total of 119 participants answered the interview conducted 1 year after the stroke. The mean (standard deviation) age was 64 (13.1) years, 82/119 (68.9%) were female, and the median (interquartile range) NIHSS score was 2 (1.0–4.0). The incidence rate of persistent headache attributed to past ischemic stroke was 12/119 (10.1%; 95% confidence interval [CI] 5.3–17.0%). The most frequent pattern presented was a migraine‐like pattern in seven of the 12 (58.3%) patients, which had a substantial/severe impact on five of the 12 (41.7%). For most patients this headache continued, although it began to improve. Previous migraine (odds ratio 7.1, 95% CI 1.06–50.0; p = 0.043) and headache intensity in the acute phase of stroke (odds ratio 1.75, 95% CI 1.13–2.7; p = 0.012) were associated with the occurrence of persistent headache attributed to past ischemic stroke. Conclusion: Persistent headache attributed to past ischemic stroke is a frequent complication after stroke. It often has a significant impact on patients' lives and presents a migraine‐like pattern as its most frequent phenotype. [ABSTRACT FROM AUTHOR]

Background: The novel coronavirus disease (COVID-19) has claimed innumerable lives globally since its onset and several extrapulmonary manifestations of the disease have been reported in association with COVID-19. Although optic neuropathy has been previously linked to a variety of infections, neuro-ophthalmological associations of SARS-CoV-2 have been sparsely reported till date. Our aim was to report the clinical profile and outcome of patients diagnosed with parainfectious/postinfectious optic neuritis (ON) associated with COVID-19. Case presentation: In this case series, we have discussed the clinical presentation, laboratory parameters and outcome in a series of three patients of ON associated with COVID-19 and also compared those findings against existing literature. Among the three patients, two patients (Case 1, 3) were incidentally diagnosed with COVID-19 during the course of hospital admission and contributed to a parainfectious association with ON, while one patient (Case 2) had an antecedent history of COVID-19 as evidenced by her antibody titers thus contributing to a postinfectious association. Notably, all these patients were asymptomatic or had mild manifestations of COVID-19 and all of them tested negative for myelin oligodendrocyte glycoprotein (MOG) antibodies. They were treated accordingly and their visual outcomes were noted in follow-up. Conclusion: ON with or without MOG seropositivity, probably attributed to molecular mimicry has surfaced up considerably in association with COVID-19. This article provides a comprehensive overview of clinical presentation and outcome of ON associated with parainfectious/postinfectious COVID-19 in three cases and a critical analysis of existing literature.
