Cognitive impairment in chronic migraine compared to pseudotumor cerebri.

INTRODUCTION: We aimed to define the prevalence of objective cognitive impairment in a group of chronic migraineurs, and to define how migraineurs with cognitive impairment differed from those without impairment, and in doing so to compare cognitive impairment in chronic migraine to another chronic headache-related disorder already associated with cognitive impairment (i.e. pseudotumor cerebri syndrome). OBJECTIVES: Cognitive impairment in migraine, especially chronic migraine, has been too little studied. Only a few studies have been done, demonstrating that cognitive impairment exists in chronic migraineurs. It is not known how this compares to other headache-related conditions. MATERIAL AND METHODS: We administered a cognitive battery consisting of the National Adult Reading Test, Mini-Mental Status Examination, Digit Span, Boston Naming Test, Rey Auditory Verbal Learning Test, Trail Making Test, Controlled Oral Word Association, and Category Fluency. Cognitive impairment was defined as mild single-domain with one test score, and mild multi- -domain with two scores more than two standard deviations below the mean for age-, gender-, and education-adjusted norms. The data from this study was compared to our previously published population of patients with pseudotumor cerebri syndrome. RESULTS: One hundred prospectively recruited patients with chronic migraine were enrolled. Fifty-seven patients had normal cognitive profiles. Forty-three patients demonstrated mild cognitive impairment, and more than half (n = 24) showed impairment in multiple cognitive domains. Migraineurs with multi-domain impairment had higher pain intensity, shorter duration of disease, were taking narcotics, had more impaired vision-related mental health scores, and worse social health scores. We found an association between objective cognitive impairment and subjective perception of impairment only when controlling for pain. We found no associations with depression and topiramate use. The mean composite cognitive Z score was no different in chronic migraineurs and patients with pseudotumor cerebri. CONCLUSIONS AND CLINICAL IMPLICATIONS: Most chronic migraineurs have normal cognitive profiles, but a large proportion of them do experience mild cognitive impairment, especially in multiple domains. The impairment seen in migraine is similar to that in pseudotumor cerebri syndrome, which has already been associated with mild cognitive impairment. Cognitively impaired migraineurs are different from non-impaired/less impaired migraineurs in several ways, which may be an important factor in influencing their migraine treatment.

Depression, anxiety and stress in Saudi migraine patients using DASS-21: local population-based cross-sectional survey.

Background: Psychiatric comorbidity is common among migraineurs, such as anxiety and depression. This type of comorbidity contributed to migraine chronicity, management efficacy, and increasing the risk for other comorbidities. This study designed to estimate the prevalence of depression, anxiety, and stress (DAS) symptoms among Saudi migraine patients using the validated instrument (DASS-21) and considering socio-demographic factors and individual differences that affect migraine progression and prognosis.Design/methods: Cross-sectional, self-administered, web-based-questionnaire distributed among Saudi Arabia general population. Only migraine patients with clinical diagnosis allowed to complete the survey.Results: A total of 247 migraine patients participated and they are predominantly females, with ages between 16 and 45 years, Saudi nationals, married, non-smokers but do not exercise regularly. About 73.3% met the abnormal score in anxiety on DASS-21, as well as 70.9% in depression and 72.3% in stress. Four statistically significant correlations with DAS were identified. Migraine patients who are smoking have a higher prevalence of depression and stress (p < 0.05). Those who do not exercise regularly have a higher prevalence only for depression (p = 0.03). A higher prevalence of all emotional states was found in patients with more than one co-morbidity and patients with a clinical diagnosis of depression and anxiety disorders (p < 0.02). The sensitivity of DASS-21 for depression and anxiety are 96.9% and 93.3%, respectively.Conclusions: Both smoking cessation and exercise to prevent migraine attacks deserve a clinical trial. A holistic approach is needed to decrease psychiatry-related disability and promote management outcomes in migraineurs. Using DASS-21 for migraine patients as a routine screening instrument is valuable to prevent psychiatric comorbidity.

Examining the correlation between salivary cytokine concentrations and CRP in people experiencing social-cognitive stress.

OBJECTIVES: The study aims to determine the relationship of migraine and chronic tension-type headache (TTHs) with alterations in the salivary markers of inflammation . METHODS: The prospective study involved 75 patients . The concentrations of inflammatory markers (CRP, IL-1 ß, and IL-6) in migraine and chronic TTH patients were determined in distinct time points: headache-free period (interictal period), during headache (ictal period), day after headache attack. The STAI-Y (State Trait Anxiety Inventory - Y) and BDI (Beck Depression Inventory) questionnaires were used to measure the level of anxiety and depression in the interictal and ictal periods. RESULTS: The interictal levels of CRP, IL1-ß, and IL-6 were significantly higher in headache groups compared to healthy controls (p < 0.001). Differences in the ictal concentrations were even stronger. Twenty-four hours after headache attack, patients with migraine and chronic TTH experienced a decrease in CRP, IL1-ß, and IL-6 levels; yet, those levels were still higher compared with the interictal ones. The repeated analysis of variance revealed no significant statistical differences in CRP, IL-ß, and IL-6 levels between the migraine and TTH groups over time (p > 0.05). Statistically higher levels of anxiety and depression were seen in unhealthy groups (p < 0.01). CONCLUSIONS: The relationship of CRP, IL1-ß, and IL-6 concentrations with migraine and chronic TTH has been established. No statistically significant differences were found in the dynamics between migraine and chronic TTH groups. There was a direct correlation of migraine and chronic TTH with anxiety and depression.

Factors implicated in response to treatment/prognosis of vestibular migraine.

PURPOSE: To identify patient factors that influence response to therapy in patients with vestibular migraines. METHODS: A retrospective cohort study was performed at a university-based tertiary medical center. PATIENTS: 47 patients evaluated for treatment of definite vestibular migraine, per the Barany Society criteria, from 2015 to 2019. INTERVENTIONS: A protocol of antidepressants, antiepileptics, beta blockers, and vestibular rehabilitation. Patients failing initial therapy received botulinum toxin per the PREEMPT protocol. Vestibular rehabilitation for motion desensitization in case of known vestibular dysfunction. OUTCOME MEASURES: Quality of life measured per the dizziness handicap inventory (DHI). Pre- and post-treatment DHI scores (total and domain scores) and change in DHI were correlated against patient-specific variables to determine factors associated with change in response to therapy. Patient factors included demographic variables, medical comorbidities, comorbid otologic or pain symptoms, treatment modality, and initial DHI scores. RESULTS: 47 patients underwent therapy for vestibular migraine. This population had a significant DHI reduction of 17.3 ± 25.2 (p < 0.001) with therapy. Univariate analysis showed that female gender, comorbid benign paroxysmal positional vertigo, and high initial DHI were significantly associated with greater reduction in DHI scores (ß = - 7.92, p = 0.033; ß = - 18.65, p = 0.028; ß = - 0.458, p = 0.016, respectively). Conversely, cervicalgia and oscillopsia were significantly associated with a lower reduction in DHI scores (ß = 5.525, p = 0.024 and ß = 21.48, p = 0.027, respectively). CONCLUSIONS: Vestibular migraine is a complex disorder with heterogeneous response to therapy. This study shows that patient-specific factors of gender, cervicalgia, oscillopsia, BPPV, and high DHI scores on presentation may influence response to common vestibular migraine therapy.

Cognitive impairment in chronic migraine: a cross-sectional study in a clinic-based sample / Comprometimento cognitivo na enxaqueca crônica: um estudo transversal em uma amostra clínica

Abstract Cognitive impairment has been described in all phases of a migraine attack and interictally. However, the prevalence and phenotype of such impairment in chronic migraine (CM) have not yet been studied. Objectives: The aim of this study was to evaluate both the prevalence of the objective cognitive deficit in patients with CM and the factors underlying its etiology. Methods: 144 patients with CM and 44 age-matched patients with low-frequency episodic migraine (EM) (a maximum of 4 headache days per month) participated in this study. Neuropsychiatric characteristics were measured with the HADS Hospital Anxiety and Depression Scale. Cognitive function was assessed with the Montreal Cognitive Assessment (MoCA), Digit Symbol Substitution Test (DSST), Rey Auditory Verbal Learning Test (RAVLT), and the Perceived Deficits Questionnaire (PDQ-20). Results: Compared to EM, CM subjects demonstrated higher subjective and objective cognitive impairment across all tests. CM patients had 4 times higher odds of achieving a RAVLT score in the lower quartile range compared to EM (Odds Ratio [OR] 3.8; 95% confidence interval [95%CI] 1.5‒9.6; р=0.005). In the MoCA, CM patients demonstrated the most striking impairment in memory/delayed recall (65.3%), attention (46.5%), abstraction (30.6%), and language (27.1%). Chronic headache and level of education, but not gender, depression or anxiety, were independent predictors of cognitive impairment. Conclusions: Cognitive impairment is prevalent in the CM population during their mildest possible pain and may be caused by a central sensitization. Timely preventive treatment of EM is warranted.

Resumo O comprometimento cognitivo foi descrito em todas as fases de um ataque de enxaqueca, de maneira intermitente. Entretanto, a prevalência e o fenótipo desse comprometimento na enxaqueca crônica (EC) não foram estudados. Objetivos: O objetivo deste estudo foi avaliar a prevalência do déficit cognitivo objetivo em pacientes com EC e fatores subjacentes à sua etiologia. Métodos: 144 pacientes com CM e 44 pacientes pareados por idade com enxaqueca episódica (EE) de baixa frequência (máximo de 4 dias de dor de cabeça por mês) foram incluídos. As características neuropsiquiátricas foram medidas pela Hospital Anxiety and Depression Scale (HADS). A função cognitiva foi avaliada por meio da Montreal Cognitive Assessment (MoCA), o Digit Symbol Substitution Test (DSST), o Rey Auditory Verbal Learning Test (RAVLT) e o Perceived Deficits Questionnaire (PDQ-20). Resultados: Em comparação com a EE, os indivíduos com EC demonstraram um comprometimento cognitivo subjetivo e objetivo maior em todos os testes. Os pacientes com CM tiveram 4 vezes mais chances de alcançar um escore RAVLT na faixa quartil inferior, em comparação com EE (Odds Ratio [OR] 3,8; intervalo de confiança de 95% [IC95%] 1,5‒9,6; p=0,005). No MoCA, os pacientes com EC demonstraram o maior prejuízo na memória/atraso na recordação (65,3%), atenção (46,5%), abstração (30,6%) e linguagem (27,1%). Dor de cabeça crônica e nível de escolaridade, mas não o sexo, depressão ou ansiedade, foram preditores independentes de comprometimento cognitivo. Conclusões: O comprometimento cognitivo é prevalente na população com enxaqueca crônica mesmo durante uma dor muito leve e pode ser causado pela sensibilização central. O tratamento preventivo oportuno da enxaqueca episódica se faz necessário.

Attachment style in children with chronic diseases: a comprehensive review / Estilo de apego em crianças com doenças crônicas: uma revisão integrativa

ABSTRACT Objective: To investigate how attachment style has been studied in children with chronic disease in the scientific literature, and what repercussions this attachment has on this population. Data sources: An integrative review of the literature was carried out from a survey in the LILACS, MEDLINE and SciELO databases, including original national and international publications in Portuguese, Spanish and English from 2007 to 2018, using the descriptors "apego" and "criança" in the Health Sciences Descriptors (DeCS), and "attachment" and "children" for the Medical Subject Headings (MeSH). Sixteen (16 articles) were obtained for the sample analysis. Data synthesis: The chronic diseases found in the research were neurobehavioral disorders such as attention deficit hyperactivity disorder (ADHD) and autism, childhood obesity, and chronic migraine. The predominant attachment style was insecurity, which could compromise the biopsychosocial development of the child. Conclusions: The type of attachment between child and primary caregiver may be considered a protective or risk factor for child development. Considering this premise, it is important to equip/inform families based on dialogic educational practices, in which professionals create opportunities and means for families to develop their skills and competencies, and acquire resources which meet the child's needs. It is important that this professional helps the family to build secure bases for their child with chronic disease, understanding that the main focus for promoting child development is in the family unit.

RESUMO Objetivo: Investigar, na literatura científica, de que forma o estilo de apego tem sido estudado nas crianças com doença crônica e as repercussões dessa vinculação nessa população. Fonte de dados: Realizou-se uma revisão integrativa da literatura por meio de um levantamento nas bases de dados Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Medical Literature Analysis and Retrieval System Online (MEDLINE) e Biblioteca Eletrônica Científica Online (SciELO) incluindo publicações originais nacionais e internacionais, em português, espanhol e inglês, no período de 2007 a 2018, utilizando-se os descritores apego e criança nos Descritores em Ciências da Saúde (DeCS) e attachment e children para o Medical Subject Headings (MeSH). Foi obtida uma amostra de 16 artigos para análise. Síntese dos dados: As doenças crônicas encontradas na pesquisa foram os distúrbios neurocomportamentais, como transtorno do déficit de atenção e hiperatividade (TDAH) e autismo, obesidade infantil e enxaqueca crônica. O estilo de apego predominante foi o inseguro, o que pode comprometer o desenvolvimento biopsicossocial dessa criança. Conclusões: O tipo de vinculação entre criança e cuidador primário pode ser considerado um fator de proteção ou risco para o desenvolvimento infantil. Haja vista essa premissa, é fundamental a instrumentalização das famílias baseada em práticas educativas dialógicas, nas quais os profissionais criam oportunidades e meios para que os familiares desenvolvam suas habilidades e competências e adquiram recursos que atendam às necessidades da criança. É importante que esse profissional auxilie a família a construir bases seguras para a criança com doença crônica, entendendo que é na unidade familiar que está o principal foco de promoção do desenvolvimento infantil.

Comparison of patients with migraine and tension-type headache in terms of somatosensory amplification and health anxiety / Estudo comparativo de pacientes com enxaqueca e cefaleia do tipo tensional em relação à amplificação somatossensorial e à ansiedade associada à saúde

ABSTRACT Although it is known that anxiety and depressive disorders frequently accompany migraine and TTH, the role of somatic amplification (SSA) and health anxiety in these diseases is not adequately known. Objective: The aim of this study is to compare SSA and health anxiety in patients with migraine or TTH, and healthy controls and to investigate the relationships between SSA, health anxiety, headache characteristics, anxiety and depressive symptoms. Methods: Fifty-four migraine, 50 TTH patients from the outpatient unit of the neurology department and 53 healthy volunteers were recruited for the study. The somatosensory amplification scale (SSAS), health anxiety inventory, Beck depression (BDI) and anxiety inventory (BAI) were administered to all participants. Results: The SSAS scores were significantly higher in migraineurs compared with the healthy controls. The health anxiety scores were significantly higher in both migraine and TTH groups. The BDI and BAI scores were also significantly higher in migraine and TTH groups compared with the controls. A significant positive correlation was found between headache frequency and BAI scores, the visual analogue scale scores and SSAS and BDI scores in migraineurs. The SSAS scores were also significantly correlated with the BDI and BAI scores in both of the headache groups. A similar correlation was determined with the health anxiety scores. Conclusions: While patients with migraine and TTH evalute, taking into account the SSA and health anxiety may contribute to the prognosis and treatment of these diseases.

RESUMO Embora se saiba que os distúrbios de ansiedade e depressão frequentemente acompanhem a enxaqueca e a TTH, o papel da amplificação somatossensorial (somatosensory amplification, SSA) e da hipocondria nessas doenças ainda não é bem conhecido. Objetivo: O presente estudo faz uma comparação entre pacientes que sofrem de enxaqueca e TTH com um grupo de controle saudável em termos de SSA e hipocondria e investiga a relação entre os achados e as características da cefaleia, a ansiedade e os sintomas depressivos. Métodos: O estudo incluiu 54 pacientes com enxaqueca, 50 pacientes com TTH e 53 voluntários saudáveis que se cadastraram na clínica de neurologia. A escala de amplificação somatossensorial (somatosensory amplification scale, SSAS), o inventário de hipocondria, o Inventário de Depressão de Beck (Beck Depression Inventory, BDI) e o Inventário de Ansiedade de Beck (Beck Anxiety Inventory, BAI) foram aplicados aos participantes. Resultados: Quando comparados com os controles saudáveis, as pontuações da SSAS dos pacientes com enxaqueca foram significativamente maiores, enquanto as pontuações de hipocondria foram significativamente maiores em ambos os grupos de enxaqueca e TTH. As pontuações do BAI e do BDI foram significativamente maiores em ambos os grupos de pacientes que no grupo de controle. No grupo da enxaqueca, foi identificada uma correlação positiva entre frequência de cefaleia e ansiedade, bem como entre a Escala Analógica Visual (EVA), a SSAS e a depressão. Em ambos os grupos de pacientes, a SSA foi correlacionada positivamente com a depressão e a ansiedade, e uma correlação semelhante foi encontrada entre a SSA e a hipocondria. Conclusão: Em avaliações dessas doenças, a hipocondria e a SSA devem ser levadas em consideração, pois se acredita que essa abordagem possa contribuir positivamente para o prognóstico e tratamento da doença.

Development and validation of the ID-EC - the ITALIAN version of the identify chronic migraine.

BACKGROUND: Case-finding tools, such as the Identify Chronic Migraine (ID-CM) questionnaire, can improve detection of CM and alleviate its significant societal burden. We aimed to develop and validate the Italian version of the ID-CM (ID-EC) in paper and as a smart app version in a headache clinic-based setting. METHODS: The study investigators translated and adapted to the Italian language the original ID-CM questionnaire (ID-EC) and further implemented it as a smart app. The ID-EC was tested in its paper and electronic version in consecutive patients referring to 9 Italian tertiary headache centers for their first in-person visit. The scoring algorithm of the ID-EC paper version was applied by the study investigators (case-finding) and by patients (self-diagnosis), while the smart app provided to patients automatically the diagnosis. Diagnostic accuracy of the ID-EC was assessed by matching the questionnaire results with the interview-based diagnoses performed by the headache specialists during the visit according to the criteria of International Classification of Headache Disorders, III edition, beta version. RESULTS: We enrolled 531 patients in the test of the paper version of ID-EC and 427 in the validation study of the smart app. According to the clinical diagnosis 209 patients had CM in the paper version study and 202 had CM in the smart app study. 79.5% of patients returned valid paper questionnaires, while 100% of patients returned valid and complete smart app questionnaires. The paper questionnaire had a 81.5% sensitivity and a 81.1% specificity for case-finding and a 30.7% sensitivity and 90.7% specificity for self-diagnosis, while the smart app had a 64.9% sensitivity and 90.2% specificity. CONCLUSIONS: Our data suggest that the ID-EC, developed and validated in tertiary headache centers, is a valid case-finding tool for CM, with sensitivity and specificity values above 80% in paper form, while the ID-EC smart app is more useful to exclude CM diagnosis in case of a negative result. Further studies are warranted to assess the diagnostic accuracy of the ID-EC in general practice and population-based settings.

Factors Associated with Migraine in the General Population of Spain: Results from the European Health Survey 2014.

OBJECTIVE: To identify the modifiable and nonmodifiable variables that are associated with and might moderate the presence of migraine in the general population. DESIGN: Nationally representative cross-sectional survey. SETTING: Noninstitutionalized population of Spain. SUBJECTS: Individuals aged 15 years or older (N = 22,842). METHODS: A secondary analysis of data from the second wave of the European Health Interview Survey conducted in Spain (2014/2015). We estimated the prevalence of migraine and its distribution according to the study variables, and then built a multivariate logistic model encompassing age, sex, depression severity, chronic anxiety, body mass index, physical activity, smoking status, alcohol use, and perceived social support to predict migraine. RESULTS: The one-year prevalence of migraine was 8%. The final multivariate model (Wald χ2 = 693.00, df = 15, P < 0.001) retained depression severity, chronic anxiety, exercising several times a month or week, and alcohol use as predictors of migraine (odds ratios = 2.1-3.5 for positive associations, odds ratios = 0.4-0.9 for negative associations). CONCLUSIONS: Raising awareness among clinicians regarding the fact that many of the variables that potentially contribute to the presence of migraine are modifiable (e.g., psychological problems and lifestyle behaviors) might intensify resources dedicated to assessing and impacting these factors in order to potentially prevent the frequency and severity of migraine.

A prevalência de cefaleia e fatores psicossociais associados em estudantes de medicina no Ceará / The prevalence of headache and psychosocial factors associated among medical students in a university of northeast Brazil

Introdução: A cefaleia é uma afecção que impacta negativamente a qualidade de vida da pessoa. O curso de medicina é reconhecidamente um gerador de esgotamento e, de acordo com a literatura, fatores estressantes são mais comuns em alunos de medicina que na população em geral, podendo desencadear a cefaleia. Esses fatores estressores podem ser intensificados em períodos que antecedem as provas devido a mudanças nos hábitos de sono e de estudo, havendo uma possível relação com o surgimento de cefaleias primárias. Objetivo: Avaliar a prevalência de cefaleia primária nos estudantes de medicina (EM) em períodos de provas e relacionar com fatores psicossociais. Métodos: Trata-se de um estudo transversal, baseado na aplicação de dois questionários a uma amostra de 219 EM do 1º ao 8º semestre de uma universidade no interior do Ceará. Um questionário relacionou a cefaleia com fatores psicossociais em períodos de provas. O segundo questionário: HSQ-DV, foi utilizado para o diagnóstico de enxaqueca e cefaleia do tipo tensional (CTT). Resultados: 98% dos EM relataram já ter sentido cefaleia. A prevalência de CTT e enxaqueca encontradas foi de 61,9% e 18,1%, respectivamente, dados maiores que a média para a população geral. Estudantes com enxaqueca têm mais crises antes de provas, se automedicam mais, ingerem mais psicoestimulantes, são mais ansiosos, mais depressivos, mais sedentários, mais estressados e dormem menos que aqueles com CTT. Conclusão: De fato, os EM são um grupo de risco para o desenvolvimento de cefaleias, merecendo, portanto, uma maior ênfase de pesquisas científicas sobre as cefaleias primárias neste grupo.

Introduction: Headache is a condition that impacts negatively the patients' quality of life. The medical course is a known generator of exhaustion and, according to the literature, stressors are more common in medical students (MS) than in the general population, which can trigger a headache. These stressors can be intensified in periods that precede the tests due to changes in sleep and in study habits, with a possible relation with the appearance of primary headache. Objective: To associate the presence of primary headache in MS during periods of tests and to relate to psychosocial factors. Methods: This is a cross-sectional study based on the application of two questionnaires to a sample of 219 MS from the 1st to the 8th semester of a university in Northeast Brazil. The first questionnaire related headache with psychosocial factors in periods of tests. The second questionnaire: HSQ-DV, was used for the diagnosis of migraine and tension-type headache (TTH). Results: 98% of MS reported having experienced headache. The prevalence of TTH and migraine was 61.9% and 18.1%, respectively, higher than the average for the general population. Students with migraine have more attacks before tests, self-medicate more, ingest more psychostimulants, are more anxious, more depressed, more sedentary, more stressed, and sleep less than those with TTH. Conclusion: In fact, MS are a risk group for the development of headache, thus deserving a greater emphasis of scientific research on primary headaches in this group

Evaluating Quality of Life in Patients With Meniere's Disease Treated as Migraine.

OBJECTIVE:: To evaluate the change in quality of life (QOL) of patients with Meniere's disease (MD) after treatment with migraine prophylaxis therapy. METHODS:: Patients with definite MD were given the Meniere's Disease Outcomes Questionnaire-Retrospective (MDOQ-R) after migraine prophylactic therapy to assess QOL. Changes in physical, emotional, and social parameters affected by MD were calculated, along with a global pre- and posttreatment QOL scores. RESULTS:: The MDOQ-R was given to 27 consecutive patients with definite MD. Patients who had at least an 18-month follow-up were included, resulting in 25 questionnaires. The mean change in QOL score was 25 ± 16 (range, -3 to 55), P = .02. Quality of life was improved in 23 (92%) of the respondents in every metric measured, unchanged in 1 (4%), and poorer in 1 (4%) of patients after migraine prophylaxis treatment. CONCLUSIONS:: Majority of MD patients who had all failed diuretic therapy responded positively to medications used for migraine prophylaxis, as indicated by a significant improvement in QOL. This study may further suggest a correlation between the pathophysiologic basis of disease in MD and vestibular migraine. Patients with MD may be successfully managed with medications intended to treat migraine.

Chronic migraine patients show cognitive impairment in an extended neuropsychological assessment / Pacientes com migrânea crônica apresentam déficits cognitivos em uma avaliação neuropsicológica estendida

ABSTRACT The objective of the present study was to assess the presence of cognitive deficits in patients with chronic migraine, and to assess the main factors that trigger cognitive disorders, such as comorbidities or the use of medications. Methods: Chronic migraine and control groups were interviewed in a case-control study. The frequency and intensity of the headache, medication used and associated comorbidities were determined. All patients were submitted to an extended neuropsychological assessment. Results: The chronic migraine group (n = 30) had a worse performance in the Montreal Cognitive Assessment Test (p = 0.00), Verbal Fluency (p = 0.00), Stroop (p = 0.00), Clock Drawing Test (p = 0.00), Digit Span (p = 0.00) and Matrix Reasoning (p = 0.01). After statistical adjustment by linear regression, migraine continued to be the only relevant factor in the poorer performance in the Montreal Cognitive Assessment, Verbal Fluency, Clock Drawing and Stroop tests. Conclusion: Patients with chronic migraine have cognitive deficits in multiple tasks, regardless of the presence of comorbidities or the use of medications.

RESUMO O objetivo do presente estudo foi avaliar a presença de déficits cognitivos em pacientes com migrânea crônica e avaliar os principais fatores que desencadeiam transtornos cognitivos, como comorbidades e uso de medicações. Métodos: Pacientes com migrânea crônica (n = 30) e controles foram entrevistados, em um estudo caso-controle. A frequência e intensidade da cefaleia, medicações utilizadas e comorbidades associadas foram determinadas. Todos os pacientes foram submetidos a uma avaliação neuropsicológica estendida. Resultados: Os pacientes com migrânea crônica apresentaram uma pior performance no Montreal Cognitive Assessment (p = 0.00), Fluência Verbal (p = 0.00), Teste de Stroop (p = 0.00), Teste do Relógio (p = 0.00), Subteste Dígitos (p = 0.00) e Raciocínio matricial da WAIS-III (p = 0.01). Após ajuste estatístico através de Regressão Linear, a migrânea se manteve como único fator relevante para pior desempenho em MoCA, Fluência verbal, Teste do relógio e Teste de Stroop. Conclusão: Pacientes com migrânea crônica apresentam déficits cognitivos incluindo múltiplas tarefas, independentes da presença de comorbidades e uso de medicações.

Evidence of Diplopia in Children's Headache Drawings Helps to Differentiate Pseudotumor Cerebri From Migraine.

OBJECTIVE: This study aimed to determine whether children's headache drawings can distinguish between pseudotumor cerebri and migraine. BACKGROUND: Headache features associated with pseudotumor cerebri (pseudotumor; idiopathic intracranial hypertension) are nonspecific and are difficult to distinguish clinically from migraines. Children's headache drawings have a high predictive value for migraine versus nonmigraine headaches. We hypothesized that drawings could help to differentiate pediatric headaches due to pseudotumor cerebri from those associated with migraines. METHODS: Children aged six to 18 years old attending university hospital pediatric neurology clinics were asked to draw a picture of how their headache feels. From our database of children's headache drawings, pictures by children with clinically diagnosed pseudotumor were compared with migraine drawings. RESULTS: Headache drawings of 21 children (16 females) with pseudotumor were compared with those of 518 children with migraine. Pseudotumor drawings depicted a variety of symptoms including pounding pain (n = 11), pressure-like pain (n = 3), photophobia (3), dizziness (1), and recumbency (1). Severe pain indicators included hammers, bombs, anvil, and vise grip. Positive visual phenomena included scintillations, scotomata, or blurring (n = 8). Negative visual phenomena included field defects (n = 2). Pseudotumor drawings were similar to migraine drawings except that 6 of 21 pseudotumor drawings (28.6%) depicted diplopia (crossed eyes, double images), whereas only three of 518 migraine drawings (0.6%) depicted diplopia (P < 0.000001). CONCLUSIONS: Diplopia was depicted in a significantly higher percentage of pseudotumor drawings than migraine drawings. In all other respects, headache drawings by children with pseudotumor cerebri were similar to those drawn by children with migraine.

Ability to Cope with Pain Puts Migraine Surgery Patients in Perspective.

BACKGROUND: Candidates for migraine surgery are chronic pain patients with significant disability. Currently, migraine-specific questionnaires are used to evaluate these patients. Analysis tools widely used in evaluation of better understood pain conditions are not typically applied. This is the first study to include a commonly used pain questionnaire, the Pain Self-Efficacy Questionnaire (PSEQ) that is used to determine patients' pain coping abilities and function. It is an important predictor of pain intensity/disability in patients with musculoskeletal pain, as low scores have been associated with poor outcome. METHODS: Ninety patients were enrolled prospectively and completed the Migraine Headache Index and PSEQ preoperatively and at 12 months postoperatively. Scores were evaluated using paired t tests and Pearson correlation. Representative PSEQ scores for other pain conditions were chosen for score comparison. RESULTS: All scores improved significantly from baseline (p < 0.01). Mean preoperative pain coping score (PSEQ) was 18.2 ± 11.7, which is extremely poor compared with scores reported for other pain conditions. Improvement of PSEQ score after migraine surgery was higher than seen in other pain conditions after treatment (112 percent). Preoperative PSEQ scores did not influence postoperative outcome. CONCLUSIONS: The PSEQ successfully demonstrates the extent of debility in migraine surgery patients by putting migraine pain in perspective with other known pain conditions. It further evaluates functional status, rather than improvement in migraine characteristics, which significantly adds to our understanding of outcome. Poor preoperative PSEQ scores do not influence outcome and should not be used to determine eligibility for migraine surgery. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Fibromyalgia Among Patients With Chronic Migraine and Chronic Tension-Type Headache: A Multicenter Prospective Cross-Sectional Study.

OBJECTIVES: To investigate the frequency and impact of fibromyalgia among patients with chronic migraine (CM) and chronic tension-type headache (CTTH). BACKGROUND: Fibromyalgia (FM) is a common comorbidity in patients with chronic headaches. CM and CTTH are the two common types of chronic headaches. METHODS: We conducted a cross-sectional study in neurology outpatient clinics of four university hospitals and selected first-visit 136 patients with CM and 35 patients with CTTH. FM was assessed based on the 2010 American College of Rheumatology diagnostic criteria. RESULTS: The frequency of FM was significantly higher among patients with CM when compared to those with CTTH (91/136 [66.9%] vs 9/35 [25.7%], P < .001). Logistic regression analyses revealed an increased odds ratio (OR) for FM for patients with CM when compared to those with CTTH after adjustment for age, sex, anxiety, depression, and insomnia (OR = 3.6, 95% confidence interval = 1.1-11.4). Furthermore, CM patients with FM had higher scores in FM Impact Questionnaire compared to CTTH patients with FM (51.5 ± 16.3 vs 43.7 ± 18.7, P = .015). Comorbidity of FM was associated with increased frequency of photophobia, phonophobia, anxiety, depression, and insomnia among patients with CM. Such association was not noted among patients with CTTH. CONCLUSION: FM based on 2010 American College of Rheumatology diagnostic criteria was more prevalent among patients with CM than those with CTTH. Some clinical features and comorbidities of CM varied with the presence of FM.

Unbalanced plasma TNF-α and IL-12/IL-10 profile in women with migraine is associated with psychological and physiological outcomes.

Increased plasma pro-inflammatory and decreased anti-inflammatory cytokines have been implicated in physiological and behavioural aspects of mood- and pain-related disorders, including migraine. In this case-control study, we assessed mood scores, cardiorespiratory fitness (VO2Peak), and plasma concentrations of TNF-α, IL-1ß, IL-6, IL-8, IL-10, and IL-12p70 interictally in women with episodic migraine with/without aura (ICHD-II), taking no preventive medicine, and in healthy women recruited from São Paulo Hospital and local community, respectively. Thirty-seven participants (mean±SD age=34±10 and BMI=26.5±4.9) were assessed. Groups (Control, n=17; Migraine, n=20) showed no differences in age, BMI, and VO2Peak. Migraine patients showed higher tension (p=0.019) and anxiety scores (p=0.046), TNF-α (p<0.01), and IL-12p70 (p=0.01), while IL-6 (p<0.01), IL-8 (p<0.01), and IL-10 (p<0.01) were decreased compared to control group. Multiple linear regression models showed that migraine was positively associated with TNF-α and IL-12p70, and negatively associated with IL-6, IL-8, and IL-10. Anxiety scores were positively associated with IL-12p70, and VO2Peak was negatively associated with TNF-α. In conclusion, an exaggeratedly skewed cytokine profile, in particular the TNF-α and 12p70/IL-10 balance may be related to migraine pathomechanisms, and its psychiatric comorbidities and functional capacity. Additional studies are needed to confirm these results.

Symptoms of central sensitization and comorbidity for juvenile fibromyalgia in childhood migraine: an observational study in a tertiary headache center.

BACKGROUND: Central sensitization is an important epiphenomenon of the adult migraine, clinically expressed by allodynia, pericranial tenderness and comorbidity for fibromyalgia in a relevant number of patients. This study aimed to evaluate the frequency and the clinical characteristics of allodynia, pericranial tenderness, and comorbidity for Juvenile Fibromialgia (JFM) in a cohort of migraine children selected in a tertiary headache center. METHODS: This was an observational cross-sectional study on 8-15 years old migraine patients. Allodynia was assessed by a questionnaire. Pericranial tenderness and comorbidity for JFM as well as their possible association with poor quality of life and migraine related disability, and with other clinical symptoms as anxiety, depression, sleep disorders and pain catastrophizing, were also evaluated. RESULTS: One hundred and fifty one patients were selected, including chronic migraine (n°47), migraine without aura (n° 92) and migraine with aura (n° 12) sufferers. Allodynia was reported in the 96,6% and pericranial tenderness was observed in the 68.8% of patients. Pericranial tenderness was more severe in patients with more frequent migraine and shorter sleep duration. Allodynia seemed associated with anxiety, pain catastrophizing and high disability scores. Comorbidity for JFM was present in the 0.03% ofpatients. These children presented with a severe depression and a significant reduction of quality of life as compared to the other patients. CONCLUSIONS: This study outlined a relevant presence of symptoms of central sensitization among children with migraine. Severe allodynia and comorbidity for JFM seemed to cause a general decline of quality of life, which would suggest the opportunity of a routine assessment of these clinical features.

Osmophobia and olfactory functions in patients with migraine.

Olfactory dysfunction and migraine has been associated for a long time. In this study, we planned to compare olfactory functions in patients with migraine and osmophobia with patients having migraine but no osmophobia, in addition with a normal control group using "Sniffin' Sticks" test. The main distinction of this study is that all qualitative and quantitative properties of olfactory functions; threshold, discrimination and identification, are evaluated separately and jointly. Thirty healthy person aged between 16 and 56 (18 women, 12 men) and 60 migraine patients aged between 15 and 54 (39 women, 21 man) were included in the study. All patients have been inquired about osmophobia and have been assessed with Hedonic tone assessment. Osmophobia has been tested for perfume, cigarette smoke, leather, stale food, soy sauce, fish, spices and coffee smells. Olfactory functions has been assessed with "Sniffin' Sticks" smell test. Thresholds, discrimination and identification have been determined for each patient. In migraine patients with osmophobia, threshold was 7.75 ± 2.3, in migraine patients without osmophobia threshold was 8.25 ± 1.5 and threshold was 10.75 ± 1.3 for the control group. Discrimination score was 6 ± 1.2 in migraine patients with osmophobia, 9 ± 0.8 in patients without osmophobia and was 12 ± 1.4 in the control group. In migraine patient with or without osmophobia Threshold/Discrimination/Identification (TDI) scores were lower than the control group. The most important parameter in our study is that discrimination scores were especially lower in patients with osmophobia. We believe that this decrease in discrimination in migraine patients with osmophobia; who claim that they smell everything and they are sensitive to all smells, is significant. Further studies about smell discrimination will help better understand some conditions; especially anosmia and hyposmia after upper respiratory tract infections and parosmia.
