Association of mental health symptoms with the migraine-tension-type headache spectrum in the Brazilian longitudinal study of adult health.

OBJECTIVE: To investigate the relationship between mental health symptoms and the migraine-tension-type headache (TTH) spectrum in middle-aged adults from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil study). METHODS: In this cross-sectional analysis (baseline data: 2008-2010), it was evaluated the relationship between each mental health symptom assessed by the Clinical Interview Schedule-Revised (CIS-R) questionnaire and headache subtypes (migraine and TTH) according to international criteria. It was performed binary logistic regression models, with estimated odds ratios (OR) with their respective 95% confidence intervals (CI) adjusted for confounders including migraine attack frequency. RESULTS: Among 13,916 participants, 70.1% reported any major primary headache subtype within the last year. The most common subtype was definite TTH (33.4%), followed by probable migraine (21.0%), definite migraine (8.5%), and probable TTH (7.2%). Our main findings indicated positive associations between anxiety-related symptoms and the migraine-tension type headache (TTH) spectrum with a clear trend toward definite migraine more than tension-type headache. The presence of somatic symptoms presented a high likelihood for the associations with headaches, mainly definite migraine (OR: 7.9, 95% CI: 6.4-9.8), probable migraine (OR: 4.5, 95% CI 3.7-5.4) and probable TTH (OR: 3.0, 95% CI: 2.3-3.8). Other symptoms associated with headache disorders included fatigue, panic, irritability, anxiety symptoms, concentration problems, forgetfulness, depressive symptoms, and worry. The effect of associations remained significant after controlling for headache attack frequency. CONCLUSION: This study provides evidence of consistent associations between mental health symptoms and primary headache disorders, with a higher burden of anxiety-based symptoms observed in people with migraine than those with TTH.

Physical activity pattern and migraine according to aura symptoms in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) cohort: A cross-sectional study.

OBJECTIVE: To estimate the associations of physical activity (PA) levels with migraine subtypes. BACKGROUND: Physical activity has been associated with reduced migraine prevalence, but less is known about its relationship with migraine subtypes and PA levels as recommended by World Health Organization (WHO). METHODS: In this cross-sectional analysis of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), we estimated the odds ratios (ORs) of migraine with aura (MA) and migraine without aura (MO), compared to participants without headaches, according to PA levels in the leisure time (LTPA), commuting time (CPA), and combined PA domains. RESULTS: In total, 2773 participants provided complete data, 1556/2773 (56.1%) were women, mean (SD) age of 52.3 (9.1) years. In this study's sample, 1370/2773 (49.4%) participants had overall migraine, 480/2773 (17.3%) had MA, and 890/2773 (32.0%) had MO. In the LTPA domain, there were reduced odds of MA (OR 0.72, 95% confidence interval [CI] 0.53-0.96; p = 0.030) and MO (OR 0.71, 95% CI 0.56-0.90; p = 0.005) in participants who met the WHO PA guidelines after adjustment for confounder variables. In the analyses stratified by intensity, moderate LTPA was associated with reduced odds of MA (OR 0.56, 95% CI 0.320-0.99; p = 0.049), while vigorous LTPA was associated with reduced odds of MO (OR 0.55, 95% CI 0.395-0.77; p = 0.001). There were no significant associations between migraine subtypes and CPA or combined PA domains. In the whole migraine sample, meeting the WHO PA guidelines in the LTPA (OR 0.275, 95% CI 0.083-0.90; p = 0.034), CPA (OR 0.194, 95% CI 0.064-0.58; p = 0.004), and combined domains (OR 0.115, 95% CI 0.032-0.41; p = 0.001) was associated with reduced odds of daily migraine attack frequency. CONCLUSIONS: Meeting the WHO PA guidelines for LTPA, but not CPA or combined PA domains, is associated with lower migraine occurrence. Moderate LTPA favors MA reduction, while vigorous LTPA favors MO reduction.

Headache disability, lifestyle factors, health perception, and mental disorder symptoms: a cross-sectional analysis of the 2013 National Health Survey in Brazil.

OBJECTIVE: To evaluate the past 2-week headache disability and explore its association with lifestyle factors, health perception, and mental disorder symptoms in the PNS 2013 survey. BACKGROUND: The prevalence of headache disorders has been associated with lifestyle factors, mental disorders, and health perception. However, less is known regarding their influence on headache-related disability. METHODS: In a cross-sectional analysis, chi-squared tests and logistic regression models computed the associations between headache-related disability (defined as days lost from work, school, or household chores in the past 2 weeks) and the variables of interest, compared to other disease-related disabilities groups or no day lost group. The adjusted models controlled for the effects of age, sex, income, and educational levels. RESULTS: In the sample aged ≥ 18 years (n = 145,580), 10,728 (7.4%) participants reported any disease-related disability in the past 2 weeks (median interquartile range (IQR) for age = 47 (33-59) years, 62% women), with the median (IQR) days lost = 5 (2-14). Headache disability represented 5.3% (572/10,728) of all diseases, constituting the 4th most prevalent disease-related disability [median (IQR) days lost = 3 (3-4)]. Among people aged 18-25 years, headache disorders ranked 2nd as the most prevalent disability (13%), headache-related disability positively associated with physical inactivity, poorer health perception, and frequent mental disorders symptoms, and negatively associated with overweight, obesity, and alcohol consumption. CONCLUSION: Headache disability represents a leading cause of disease-related disability in Brazil and associates with unhealthy lifestyle factors, poorer health perception, and frequent mental disorder symptoms.

Physical inactivity and headache disorders: Cross-sectional analysis in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

BACKGROUND: Physical inactivity has been linked to headache disorders but estimates based on the current World Health Organization physical activity guidelines are unknown. OBJECTIVE: To test the associations between headache disorders and physical inactivity in the ELSA-Brasil cohort. METHODS: In a cross-sectional analysis, linear (continuous variables) and logistic regression models (categorical variables) tested the associations of physical activity levels in the leisure time, commuting time, and combined leisure time physical activity + commuting time physical activity domains with headache disorders, adjusted for the effects of sociodemographic data, cardiovascular risk variables, psychiatric disorders, and migraine prophylaxis medication. RESULTS: Of 15,105 participants, 14,847 (54.4% women) provided data on physical activity levels and headache. Higher physical activity levels (continuous values) in the leisure time physical activity domain associated with lower migraine and tension-type headache occurrence and lower headache attack frequency, while in the commuting time physical activity domain it associated with more frequent headache attacks. Compared to people who met World Health Organization physical activity levels in the leisure time physical activity or combining leisure time physical activity + commuting time physical activity domains (i.e. ≥150 min.wk-1 of moderate and/or ≥75 min.wk-1 of vigorous physical activity), physical inactivity associated with higher migraine occurrence, while somewhat active (i.e. not meeting World Health Organization recommendations) associated with higher migraine and tension-type headache occurrence. Physical inactivity in the commuting time physical activity domain associated with higher tension-type headache in men and lower migraine in women. Physical inactivity within vigorous leisure time physical activity intensity, but not moderate leisure time physical activity, associated with higher migraine, mostly in women. Finally, physical inactivity associated with higher headache attack frequency regardless headache subtype. CONCLUSION: Physical inactivity and unmet World Health Organization physical activity levels associate with primary headaches, with heterogeneous associations regarding headache subtype, sex, physical activity domain/intensity, and headache frequency in the ELSA-Brasil study.

Fatores associados ao uso excessivo de medicação sintomática em pacientes com enxaqueca crônica / Factors associated with acute medication overuse in chronic migraine patients

OBJETIVO: Avaliar a prevalência de transtornos psiquiátricos em pacientes com diagnóstico de enxaqueca crônica com e sem uso excessivo de medicação sintomática. MÉTODOS: Setenta e dois voluntários foram recrutados a partir de um Programa de Saúde da Família da comunidade de Paraisópolis, na cidade de São Paulo (SP). Esses pacientes foram submetidos a exames clínico e neurológico. As seguintes variáveis foram analisadas: idade, gênero, nível educacional, índice de massa corporal, tipo de uso excessivo de medicação, características da cefaleia, consumo de cafeína, presença de ansiedade e distúrbios de humor. RESULTADOS: Dos 72 pacientes, 50 (69%) tinham cefaleia crônica, com uso exagerado de medicação, e 22 (31%) tinham cefaleia crônica, sem uso excessivo de medicação. Os fatores idade, gênero, nível educacional, índice de massa corporal, tipo de uso excessivo de medicação, características da cefaleia e consumo de cafeína não mostraram diferença significante entre os grupos estudados. Os diagnósticos de ansiedade e de distúrbios de humor ao longo da vida foram mais comuns nos pacientes com uso excessivo de medicação (p=0,003 e p=0,045, respectivamente). CONCLUSÃO: Este estudo mostrou uma associação significativa entre cefaleia crônica e uso excessivo de medicação nos pacientes avaliados, quanto ao diagnóstico de transtornos de ansiedade e de humor ao longo da vida. Não foi encontrada nenhuma associação com outros distúrbios psiquiátricos pesquisados.

OBJECTIVE: To evaluate the prevalence of psychiatric disorders in patients diagnosed with chronic migraine with and without acute medication overuse. METHODS: Seventy-two volunteers were recruited from a Family Health Program of the Paraisópolis community in São Paulo (SP), Brazil. These patients were submitted to a detailed headache questionnaire. All participants were submitted to physical and neurological examinations. The following variables were analyzed: age, gender, education level, body mass index, type of overused medication, headache characteristics, and caffeine consumption, lifetime anxiety and mood disorders. RESULTS: Out of 72 patients, 50 (69%) had chronic migraine with medication overuse, and 22 (31%) had chronic migraine without medication overuse. Factors such as age, gender, education level, body mass index, type of overused medication, headache characteristics, and caffeine consumption were not significantly different between the two studied groups. Lifetime anxiety and mood disorders were more common in patients with acute medication overuse (p=0.003 and p=0.045, respectively). CONCLUSION: This study has shown a significant association among chronic migraine and medication overuse with lifetime mood and anxiety disorders in patients of the studied population. No association was found for other researched psychiatric disorders.

Anxiety and fear-avoidance in musculoskeletal pain.

Musculoskeletal pain (MP) is common in the general population and has been associated with anxiety in several ways: (a) muscle tension is included as a part of the diagnostic criteria for generalized anxiety disorder, (b) pain can be a common symptom and a good indicator of an anxiety disorder, (c) anxiety is an independent predictor of quality of life in patients with chronic MP, (d) anxiety leads to higher levels of pain chronification, and (e) fear, anxiety, and avoidance are related to MP. The objective of this article is to explore the mechanisms underlying the relation between anxiety disorders and musculoskeletal pain as well as its management. We have also highlighted the role of spirituality and religiosity in MP treatment. We found some similarities between proposed mechanisms and explicative models for both conditions as well as an overlapping between the treatments available. The recognition of this association is important for professionals who deal with chronic pain.

Trigger factors in migraine patients.

BACKGROUND: Migraine is a chronic neurological disease with several trigger factors, including dietary, hormonal and environmental factors. PURPOSE: To analyse precipitating factors in a sample of migraine patients. METHOD: Two hundred consecutive migraine patients were interviewed about possible trigger factors for migraine attacks. RESULTS: Most patients showed at least one dietary trigger, fasting was the most frequent one, followed by alcohol and chocolate. Hormonal factors appeared in 53%, being the pre-menstrual period the most frequent trigger. Physical activities caused migraine in 13%, sexual activities in 2.5% and 64% reported emotional stress a trigger factor. 81% related some sleep problem as a trigger factor. Regarding environmental factors, smells were reported by 36.5%. CONCLUSION: Trigger factors are frequent in migraine patients, its avoidance may decrease headache frequency and also improve patients' quality of life.

[Psychiatric comorbidities decrease quality of life in chronic migraine patients]. / Comorbidade psiquiátrica diminui a qualidade de vida de pacientes com enxaqueca crônica.

INTRODUCTION: Chronic migraine is a common, debilitating condition affecting quality of life and social functioning with significant impact. Migraine is highly comorbid with anxiety and mood disorders, but little is known about psychiatric comorbidities impact in the migraine patient quality of life. METHOD: Fifty patients with chronic migraine diagnosed according to the International Headache Society (2004) were interviewed and met diagnostic criteria for mental disorders, according to the structured interview SCID-I/P and were evaluated by the SF-36 Health Survey questionnaire. Patients were divided in the following groups: chronic migraine with both mood and anxiety disorders, with only anxiety disorders, with generalized anxiety disorder, with only a mood disorder, and without psychopathology. The scores in the group without psychopathology were compared with the other groups. All eight domains of the SF-36 scale were compared in those groups. RESULTS: Significantly lower (p<0.05) quality of life was found on all eight SF-36 domains for CM psychiatric comorbidity patients compared to no-co morbidity patients. On the SF-36 General Health domain alone, quality of life was not significantly lower for all four CM psychiatric comorbidity groups. On the SF-36 Physical Aspects domain alone, quality of life was not significantly lower only for the Anxiety Disorders group. CONCLUSION: Chronic migraine comorbidity with mental disorder is a significant factor affecting patients' quality of life.

Comorbidade psiquiátrica diminui a qualidade de vida de pacientes com enxaqueca crônica / Psychiatric comorbidities decrease quality of life in chronic migraine patients

INTRODUÇÃO: A enxaqueca apresenta elevada comorbidade com os transtornos de humor e de ansiedade e extremo impacto no grau de incapacidade e qualidade de vida do indivíduo afetado, mas pouco se sabe sobre a qualidade de vida dos pacientes com enxaqueca crônica e o impacto das comorbidades psiquiátricas. MÉTODO: Cinquenta pacientes com diagnóstico de enxaqueca crônica (Sociedade Internacional de Cefaléias, 2004) foram diagnosticados quanto à presença de transtornos mentais, através da entrevista estruturada SCID-I/P e do questionário de qualidade de vida SF-36. Pacientes foram divididos nos seguintes grupos: enxaqueca crônica com transtornos de ansiedade, transtorno de ansiedade generalizada, transtornos de ansiedade com pelo menos um episódio depressivo maior, com episódio depressivo maior, comparados a pacientes sem comorbidade psiquiátrica. RESULTADOS: Constatou-se qualidade de vida significativamente inferior nos oito domínios da SF-36, nos pacientes com enxaqueca crônica associada a comorbidade psiquiátrica tais como transtornos de ansiedade, transtorno de ansiedade generalizada, transtornos de ansiedade com pelo menos um episódio depressivo maior, assim como nos pacientes apenas com episódio depressivo maior, comparados a pacientes com enxaqueca crônica sem comorbidade psiquiátrica (p<0,05). Somente no domínio Estado Geral de Saúde do SF-36, a qualidade de vida não foi significativamente inferior em todos os grupos de pacientes com enxaqueca crônica associada a comorbidade psiquiátrica. Nos domínios do SF-36 relacionados aos aspectos físicos, a qualidade de vida não foi significativamente inferior somente nos transtornos de ansiedade. CONCLUSÃO: A comorbidade da enxaqueca crônica e transtornos mentais é fator associado à piora da qualidade de vida dos pacientes e deve ser ativamente pesquisada nesta população.

Comorbidade entre cefaléias primárias e transtorno de ansiedade generalizada / Primary headaches and generalized anxiety disorder comorbidity

INTRODUÇÃO. A comorbidade entre cefaléias e transtornos psiquiátricos vem sendo enfatizada como um dos aspectos mais importantes no manejo dos pacientes com cefaléias primárias. Os transtornos de ansiedade, além dos de humor, são um dos diagnósticos de maior importância neste contexto. O transtorno de ansiedade generalizada (TAG) é o transtorno de ansiedade mais associado à enxaqueca. Apesar da relevância do tema, é surpreendente a escassez de estudos sobre o impacto das cefaléias primárias em pacientes com TAG. OBJETIVO. O objetivo deste estudo foi de avaliar a prevalência ao longo da vida e o impacto das cefaléias primárias em pacientes com e sem TAG. MÉTODOS. Sessenta pacientes foram incluídos no estudo: 30 pacientes com diagnóstico de TAG, de acordo com a entrevista estruturada SCID-1/P, e 30 controles saudáveis. Todos os pacientes passaram por entrevista clínica enfocando variáveis demográficas (idade, sexo, escolaridade e estado civil), antropométricas (peso, altura e IMC), relativas às cefaléias (intensidade, duração, freqüência, aura, tempo de história e consumo de analgésicos), gravidade da sintomatologia (ansiosa, depressiva, de fadiga e de sonolência diurna) e conseqüências médico-sociais (incapacidade funcional, utilização de serviços de saúde e qualidade de vida). As cefaléias primárias foram avaliadas através de entrevista estruturada e foram empregados os critérios da Classificação Internacional das Cefaléias (2a edição) para realização de seu diagnóstico. RESULTADOS. 86,6% dos pacientes com TAG receberam algum diagnóstico de cefaléia, sendo a enxaqueca o diagnóstico mais comum. Comparados aos controles, os pacientes com TAG apresentaram odds ratio maior para cefaléias primárias (RC=7,43) e também para enxaqueca (RC=13,00), enxaqueca episódica (RC=6,88) e aura (RC=10,55). Já nos controles, apenas 47% receberam algum diagnóstico de cefaléia, sendo CTT episódica infreqüente o diagnóstico mais comum...

OBJECTIVES. Anxiety disorders and headaches are comorbid conditions, but no research has been done on the prevalence and impact of primary headaches in generalized anxiety disorder (GAD) patients. The study's aim was to analyze lifetime prevalence and impact of primary headaches in patients with and without generalized anxiety disorder. METHODS. Sixty participants were enrolled in the study; 30 GAD patients diagnosed according to the DSM-IV were compared to 30 healthy control subjects. All patients were interviewed for psychiatric assessment using the SCID-I/P. Primary headaches were diagnosed using ICHD-II criteria for structured interview. RESULTS. Migraine was the most common diagnosis in generalized anxiety disorder patients. The prevalence of migraine was highest among GAD patients as opposed to controls (66.7% vs 13.3%; p<0.001; OR=13.00; 95% CI=3.55-47.6), episodic migraine (43.3% vs 10%; p=0.004; OR=6.88; 95% CI=1.71-27.75), chronic daily headache (20% vs 0; p=0.024) and aura (26.6% vs 3.3%; p=0.026; OR=10.55; 95% CI=1.23-90.67). Tension Type Headache (TTH) was equal for controls and the GAD group (20% vs 33.3%; p=0.243).The characteristics of migraines (frequency, intensity, duration, and consumption of analgesics), symptoms such as anxiety, depression, fatigue, and daytime sleepiness, as well as the medical-social consequences (functional incapacity, use of health services and quality of life) were worse in GAD patients than in controls. CONCLUSION. Primary headaches in general, and migraine in particular, are significantly more common in GAD patients than controls. GAD aggravates headaches. Primary headache diagnosis is important for anxiety disorder patients, particularly those with GAD, since correct assessment may lead to better patient management and clinical outcomes.

Depression in chronic migraine: severity and clinical features.

INTRODUCTION: Chronic migraine (CM) is a common medical condition affecting 2.4% of the general population. Depression is one of the most frequent comorbid disorders in CM. METHOD: Seventy patients diagnosed with chronic migraine were studied. All patients evaluated filled out the Beck Depression Inventory (BDI). Depression severity was divided into none or minimal depression, mild, moderate, and severe. RESULTS: BDI ranged from 4 to 55, mean 21 +/- 10.7. Moderate or severe depression, were present in 58.7% of the patients. Some degree of depression appeared in 85.8% of patients. The BDI scores correlated with pain intensity (p = 0.02). Severe depression was more frequent in patients with comorbid fibromyalgia and in patients reporting fatigue. CONCLUSION: The BDI is an easy tool to access depression in CM patients. Suicide risk assessment is needed in CM patients. Patients with fibromyalgia and fatigue are at even higher risk for severe depression.

Depression in chronic migraine: severity and clinical features

INTRODUÇÃO: A migrânea crônica (MC) é uma doença comum, que afeta 2,4% da população geral. A depressão é uma das comorbidades mais frequentes em enxaqueca. MÉTODO: Setenta pacientes diagnosticados com migrânea crônica foram estudados. Todos os pacientes preencheram o Inventário de Depressão Beck.(BDI). A gravidade da depressão foi dividida em nenhuma ou leve, mínima, moderada, e grave. RESULTADOS: O BDI variou de 4 a 55, média 21 ± 10,7. A depressão moderada ou grave esteve presente em 58,7% dos pacientes. Algum grau de depressão foi observado em 85,8% dos pacientes. Os escores de depressão correlacionaram-se com a intensidade da dor. A depressão grave foi mais freqüente em paciente com comorbidade com fibromialgia e fadiga. CONCLUSÃO: O BDI é um instrumento de fácil avaliação da depressão em MC. A identificação do risco de suicídio é necessária nestes pacientes. Fibromialgia e fadiga são fatores de risco para depressão grave.
