Treatment of migraine in children and adolescents. The state of the art / Tratamento da enxaqueca em crianças e adolescentes. O Estado da arte

Introduction: Headaches and migraine are common in the pediatric population, being one of the most frequent symptoms reported in practice. Additionally, it is a considerably disabling condition, which brings significant burden and impairs several aspects of a child or adolescent's life, such as mental and physical health, executive functioning, school performance. Children and adolescents with migraine have higher risk of psychiatric comorbidities and psychosocial adjustment difficulties, which, in turn, compromise even more patient's well functioning. Objective:The present article provides the clinician with a straightforward and evidence-based approach to migraine treatment in this age group. Comment: Treatment of migraine in children and adolescents requires a systematic and thorough approach. Clinicians should keep in mind the important burden migraine brings to a child's life, thus investigate, and properly manage comorbidities presented. Patient and parents' education is a meaningful part of the treatment. Moreover, non-pharmacological treatments, such as healthy lifestyle habits, behavioral interventions may also play beneficial roles. When preventive treatment is indicated, it should be tailored considering drug's profile of effectiveness and safety, as well as patient's comorbidities. Lack of evidence in this context must not translate in lack of action by the clinician, since there may be a relevant burden associated. Therefore, reasoning for the perspicacious clinician is of fundamental importance and may influence positively the outcomes.

Introdução: Dores de cabeça e enxaqueca são comuns na população pediátrica, sendo um dos sintomas mais frequentes relatados na prática. Além disso, é uma condição consideravelmente incapacitante, que traz sobrecarga significativa e prejudica diversos aspectos da vida de uma criança ou adolescente, como saúde mental e física, funcionamento executivo, desempenho escolar. Crianças e adolescentes com enxaqueca apresentam maior risco de comorbidades psiquiátricas e dificuldades de ajustamento psicossocial, o que, por sua vez, compromete ainda mais o bom funcionamento do paciente. Objetivo: O presente artigo fornece ao médico uma abordagem simples e baseada em evidências para o tratamento da enxaqueca nesta faixa etária. Comente: O tratamento da enxaqueca em crianças e adolescentes requer uma abordagem sistemática e minuciosa. Os médicos devem ter em mente o importante fardo que a enxaqueca traz à vida de uma criança, investigando e gerenciando adequadamente as comorbidades apresentadas. A educação do paciente e dos pais é uma parte significativa do tratamento. Além disso, os tratamentos não farmacológicos, como hábitos de vida saudáveis ​​e intervenções comportamentais, também podem desempenhar papéis benéficos. Quando indicado tratamento preventivo, este deve ser adaptado considerando o perfil de efetividade e segurança do medicamento, bem como as comorbidades do paciente. A falta de evidências neste contexto não deve traduzir-se em falta de ação por parte do médico, uma vez que pode haver um ónus relevante associado. Portanto, o raciocínio do clínico perspicaz é de fundamental importância e pode influenciar positivamente os resultados.

Associated Factors of Attention-Deficit/Hyperactivity Disorder Diagnosis and Psychostimulant Use: A Nationwide Representative Study.

BACKGROUND: Connections between epidemiological findings and children's and adolescents' mental health policies have not been properly made in Brazil, and such nationwide studies are scarce. This epidemiological study (1) estimated the prevalence and predictors of parent-reported attention-deficit/hyperactivity disorder (ADHD) (ADHD-report), (2) estimated the probable diagnosis and risk of ADHD based on Diagnostic and Statistical Manual of Mental Disorders, 5th edition, criteria (ADHD-probable), and (3) estimated current psychostimulant use (ADHD-pst) in a representative nationwide sample of Brazilian school-aged children and adolescents. METHODS: Data were obtained from 7114 school-aged children (49.9% boys) from 87 cities in 18 Brazilian states. Parents and teachers were interviewed using psychometrically sound questionnaires. Data and codes are available. RESULTS: The prevalence of ADHD-report, ADHD-probable, and ADHD-pst were 7.1%, 3.9%, and 1.9%, respectively. The agreement was low between ADHD-probable and ADHD-report (22.6%) and between ADHD-report and ADHD-pst (15.6%). Logistic regression revealed that predictors of all three categories were male gender (odds ratio [OR] = 1.71, 2.32, and 1.96, respectively), divorced parents (OR = 1.47, 1.65, and 1.68, respectively), and below-expectation school performance (OR = 3.1, 13.74, and 3.95, respectively). Socioeconomic status was a significant predictor of ADHD-report, and participants from lower classes were less frequently diagnosed with ADHD than their peers from upper classes (OR = 0.57, 95% confidence interval = 0.37-0.88, P = 0.012). CONCLUSIONS: The present findings provide an accurate description of ADHD in Brazil. We suggest disparities in agreement between report, risk, and psychostimulant use among children and adolescents and discrepancies between socioeconomic classes concerning the prevalence of an ADHD diagnosis.

Psychometric properties and clinical utility of the executive function inventory for children and adolescents: a large multistage populational study including children with ADHD.

Executive functions (EF) are a set of high order mental abilities that regulate cognition, emotions, and behavior. This study aims to report the construction and validation of a rating scale instrument for EF in children and adolescents aged from 5 to 18 years (EFICA), as well as to report the results of a comparison between children with ADHD and their peers without it. Thus, we conducted a population-based cross-sectional study relying on a sample composed of 3,284 typical children and adolescents accessed to study the psychometric properties of the parents' inventory (EFICA-P) and the teacher's inventory (EFICA-T) within a Structural Equation Modeling framework (SEM). Exploratory and confirmatory analyses were fitted, as well as the Cronbach's alpha and the McDonald's omega reliability indices. The known-groups method was carried out by independent Welch t-tests between untreated ADHD children and their peers. We concluded that the parents' inventory is composed of three dimensions (Cool Index 1, Cool Index 2, and Hot Index): χ2 (1,649) = 4,607.852 p < .01, CFI = .965, TLI .963, RMSEA = .053, whereas the teachers´ inventory is composed of two dimensions (Cool Index and Hot Index): χ2 (1,273) = 5,158.240, p < .01, CFI = .991, TLI = .991, RMSEA = .077. The internal consistency of both inventories was >.9. Significant differences between the ADHD groups were found in all domains accessed. These findings indicate that both inventories have a high degree of validity regarding their internal structures, as well as supporting their clinical utility.

Resilience and vulnerability in adolescents with primary headaches: A cross-sectional population-based study.

BACKGROUND: A scarcity of studies on the role of resilience resources (RRs) and vulnerability risk (VR) in children and adolescents with primary headache hampers the development of a risk-resilience model for pediatric headaches. OBJECTIVE: To examine the extent to which headache frequency and diagnosis are associated with RRs and VR and explore possible predictors of low RRs and high VR in a cross-sectional population-based study in adolescents. METHODS: This is a cross-sectional population study conducted in a small city in Brazil (Delfinópolis). Consents and analyzable data were obtained from 339/378 adolescents (89.7%). RRs and VR were assessed using the validated Brazilian version of the Resiliency Scales for Children and Adolescents, completed by the adolescents. Parents filled a structured questionnaire assessing sociodemographic and headache characteristics, as well as the Brazilian-validated version of the Strengths and Difficulties Questionnaire added to the impact supplement to evaluate the adolescent's psychosocial adjustment skills. Teachers completed a structured questionnaire about the students' school performance. RESULTS: A higher frequency of headache was associated with lower RRs (F3,335  = 2.99, p = 0.031) and higher VR (F3,335  = 4.05, p = 0.007). Headache diagnosis did not significantly influence the risk of having lower RRs or higher VR. In the exploratory analyses, females (OR 3.07; 95% CI: 1.16-9.3) and individuals with psychosocial adjustment problems (OR 7.5; 95% CI: 2.51-22.4) were predictors of low RRs, and prenatal exposure to tobacco (OR 5.6; 95% CI: 1.57-20.9) was a predictor of high VR in adolescents with primary headache. CONCLUSIONS: The risk of low RRs and high VR was associated with a higher headache frequency, but not with headache diagnosis. These findings may contribute to the development of a risk-resilience model of headaches in the pediatric population and help identify novel targets and develop effective resources for successful interventions.

ADHD Is Comorbid to Migraine in Childhood: A Population-Based Study.

Objective: Recurrent headaches and ADHD are prevalent in the pediatric population. Herein, we assess if ADHD is comorbid to headaches overall, to headache subtypes (e.g., migraine), and to headache frequency. Method: Informed consent and analyzable data were obtained for 5,671 children aged 5 to 12 years (65.9% of the target sample). Parents and teachers were interviewed using validated questionnaires based on the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5). Relative risks were modeled using univariate and multivariate analyses. Results: As contrasted to nonheadache controls, the prevalence of ADHD was significantly higher in children with migraine (p < .001) but not in those with tension-type headaches. In children with migraine, risk of ADHD increased as a function of headache frequency (p < .05). Conclusion: Migraine and frequent migraine are comorbid to ADHD. Future studies should focus on the impact of the association on the burden to the children and their families.

Painful Temporomandibular Disorder Is Associated With Migraine in Adolescents: A Case-Control Study.

Some types of primary headaches and temporomandibular disorders (TMD) are comorbid in adults and highly prevalent in adolescents. Herein, we investigated the association of painful TMD with specific headache diagnoses (migraine, tension-type headache) and with headache frequency in adolescents. We also explored the association of headache diagnosis with the number of painful sites in the trigeminal area. Painful TMD was assessed using the Research Diagnostic Criteria for TMD. We conducted a case-control study of adolescents from 13 to 15 years old who were recruited among participants in a previous epidemiologic study conducted in Araraquara, SP, Brazil. Headaches were classified according to the second edition of the International Classification for Headache Disorders. Logistic, multinomial logistic and linear regression models were used to test associations. Of 149 individuals, 55.7% presented painful TMD. Adolescents with painful TMD (cases) were more likely to have migraine compared with those without TMD (controls; odds ratio = 3.0, 95% confidence interval = 1.47-6.19, P = .033). Significant differences were not observed for probable tension-type headache (P = .307) or tension-type headache (P = .834). Painful TMD was also associated with an increase in headache frequency (linear-by-linear association = 8.051; P = .005). Only migraine was associated with a greater number of painful sites on palpation in the trigeminal area (P = .001). Migraine and frequency of headache were associated with painful TMD in adolescents. PERSPECTIVE: Migraine and headache frequency were strongly associated with painful TMD in adolescents, and causality must be determined. For now, the presence of 1 condition should raise suspicion of the other and warrants collaboration between orofacial pain specialists and neurologists.

Recent advances in the management of chronic migraine in children.

INTRODUCTION: Migraine is a chronic-recurrent disorder that progresses in some adults and also in many children. Chronic migraine (CM) is the clinical result of this process. Since migraine does not progress in most children, identifying the risk factors for progression is an important public health priority that should be matched by evidence-based treatment. Areas covered: Herein we conduct a systematic review on the comorbidities and treatment of CM in children and adolescents in the last ten years, summarizing evidence-based recommendations for disease management. Expert commentary: By conceptualizing CM as the result of migraine progression from an episodic form, we suggest avoiding CM at the outset through development of aggressive, preventive interventions as the goal of headache management in the pediatric population. Key interventions include: Decreasing headache frequency with behavioral and pharmacologic interventions; Monitoring body mass index and encouraging maintenance of normal weight; Avoiding medication overuse; Screening and treating comorbidities.

Prenatal exposure to tobacco and alcohol are associated with chronic daily headaches at childhood: A population-based study.

The influence of prenatal events on the development of headaches at childhood has not been investigated and is the scope of our study. Of 2,173 children identified as the target sample, consents and analyzable data were provided by 1,440 (77%). Parents responded to a standardized questionnaire with a validated headache module and specific questions about prenatal exposures. Odds of chronic daily headache (CDH) were significantly higher when maternal tabagism was reported. When active and passive smoking were reported, odds ratio (OR) of CDH were 2.29 [95% confidence intervals (CI)=1.6 vs. 3.6)]; for active tabagism, OR=4.2 (95% CI=2.1-8.5). Alcohol use more than doubled the chance of CDH (24% vs. 11%, OR=2.3, 95% CI=1.2-4.7). In multivariate analyses, adjustments did not substantially change the smoking/CDH association. Prenatal exposure to tobacco and alcohol are associated with increased rates of CDH onset in preadolescent children.

A influência de eventos pré-natais na fisiopatogenia das cefaleias na infância ainda não foi investigada e é o objetivo desse estudo. Da amostra-alvo de 2.173 crianças, um consentimento pós-informado e dados suficientes para as análises foram obtidos de 1.440 (77 por cento). Os pais responderam a um questionário padrão com um módulo de cefaleia validado na população brasileira e questões específicas sobre antecedentes pré-natais. O risco de cefaleia crônica diária (CCD) foi significativamente maior nas crianças cujas mães fumaram durante a gestação. Quando presentes tabagismo ativo e passivo, o risco (OR) de CCD foi de 2,29 [intervalo de confiança (IC) de 95 por cento=1,6-3,6)]; para tabagismo ativo, OR=4,2 (IC 95 por cento=2,1-8,5). O uso de álcool durante a gestação dobrou o risco de CCD (24 por cento vs. 11 por cento, OR=2,3, IC 95 por cento=1,2-4,7). Nas análises multivariadas, os ajustes não modificaram, substancialmente a associação entre tabagismo materno durante a gestação e CCD. A exposição pré-natal ao tabaco e ao álcool encontra-se associada à CCD de início na infância.

An epidemiologic study of headaches in Brazilian schoolchildren with a focus on pain frequency.

The purpose of this study was to assess the prevalence and frequency of the headaches in Brazilian schoolchildren. A cross-sectional study was conducted between March and November 2004 in São José do Rio Preto, São Paulo State, Brazil. A sample of 5,232 children from elementary schools was selected using proportional stratified sampling method. To collect data, a questionnaire was handed out in the schools to the schoolchildren to be answered by parents or guardians. From the total answers received, 84.2% reported headache complaints during the last year. There were significant complaint differences between males and females. Females were reported as having more frequent headaches than males with daily ones occurring twice as many times. A greater headache frequency was also reported for increasing age. The study has shown that headache prevalence was high, with a predominantly higher frequency (monthly, weekly and daily) with girls and older age groups.

A cefaleia é um dos sintomas mais frequentes da espécie humana e na infância uma das principais queixas na clínica pediátrica e neuropediátrica. A enxaqueca é a causa mais frequente de cefaleia crônica na infância e adolescência e apresenta, nessa faixa etária, numerosas peculiaridades diagnósticas e terapêuticas. O autor analisa tais peculiaridades e apresenta um roteiro para o diagnóstico e tratamento agudo e profilático desta cefaleia através de evidências científicas extraídas da literatura atual.

Propranolol vs flunarizine vs flunarizine plus propranolol in migraine without aura prophylaxis

Fourty-five migraine without aura patients underwent a parallel double-blind trial aiming the comparison of the effects of propranolol 60 mg/day to flunarizine 10 mg/day and to propranolol 60 mg/day plus flunarizine 10 mg/day simultaneously. There were 3 groups, each one with 15 patients. After a 20-day-baseline period, each group received one kind of treatment during 120 days. Migraine index on propranolol was 23.4*, on flunarizine 18,7* and on both drugs 14.4*, mean frequency of attacks on propranolol was 1.26**, on flunarizine 1.2** and on both drugs, 1.13** (*p<0.05, **p<0.01 compared to baseline) and global evaluation was reduced with all forms of treatment. It was not found statistical differences between groups, nevertheless there was a trend in the group using two drugs reaching lower values in migraine index, frequency of attacks and global evaluation. In individuals using flunarizine (alone or associated with propranolol) the therapeutic effect was largely maintained up to 45 days after drug withdrawal.
