Is there an association between perinatal complications and ttention-deficit/hyperactivity disorder-inattentive type in children and adolescents? / Existe alguma associação entre complicações perinatais e transtorno de déficit de atenção/hiperatividade - subtipo desatento em crianças e adolescentes?

OBJECTIVE: The objective of the present study is to investigate the association between attention deficit/hyperactivity disorder (ADHD), predominantly inattentive type (ADHD-I) and prenatal, delivery and early postnatal complications (PDPC). METHOD: In a case-control design, we assessed a sample of 124 children and adolescents with ADHD-I and 124 non-ADHD controls (6-17 years old) from both a non-referred (n = 200) and a clinical sample (n = 48). Cases and controls, matched by gender and age, were systematically evaluated through structured diagnostic interviews. Prenatal, delivery and early postnatal complications (PDPC), as well as potential confounders were evaluated by direct interview with biological mothers. RESULTS: Conditional logistic regression analysis showed that children and adolescents whose mothers presented more PDPC had a significantly higher risk for ADHD-I (p = 0.005; OR = 1.25; CI 95%: 1.1-1.5). CONCLUSIONS: In a case-control study, we expanded to ADHD-I previous findings suggesting the association between perinatal factors and broadly defined ADHD. Due to the preventable nature of some of these PDPC, our results have clear impact in public mental health policies.

OBJETIVO: O objetivo desse estudo é investigar a associação entre complicações perinatais (complicações ocorridas nos períodos pré, peri e pós-natal imediato -CPPs) e transtorno de déficit de atenção/hiperatividade (TDAH) do subtipo desatento (TDAH-D). MÉTODO: Em um estudo de casos e controles, foram avaliadas 124 crianças e adolescentes (6-17 anos) com TDAH-D e 124 controles sem a doença, provenientes tanto de uma amostra populacional (n = 200), quanto de uma amostra clínica (n = 48). Casos e controles, pareados por gênero e idade, foram sistematicamente avaliados através de entrevistas diagnósticas estruturadas. Informações sobre as complicações ocorridas durante os períodos pré, peri e pós-natal imediato (CPPs), assim como sobre potencias confundidores, foram obtidas através de entrevistas realizadas diretamente com as mães biológicas. RESULTADOS:A análise de regressão logística condicional mostrou que para as crianças e adolescentes cujas mães apresentaram maior número de CPPs, o risco de TDAH-D foi significativamente mais elevado (p = 0.005; OR = 1.25; IC 95%: 1.1-1.5). CONCLUSÕES: Em um estudo de caso-controle, foi possível expandir, para o TDAH predominantemente desatento, os achados prévios que sugeriam a associação entre complicações perinatais e TDAH sem um subtipo específico. Em virtude da possibilidade de prevenção de algumas dessas complicações, nossos resultados podem exercer impacto sobre políticas públicas de saúde.

Methylphenidate combined with aripiprazole in children and adolescents with bipolar disorder and attention-deficit/hyperactivity disorder: a randomized crossover trial.

In clinical samples, juvenile bipolar disorder (JBPD) is frequently accompanied by co-morbid attention-deficit/hyperactivity disorder (ADHD). Clinical trials assessing combined psychopharmacological interventions in this population are scarce, and methylphenidate (MPH) may worsen manic symptoms. We conducted a randomized crossover trial with MPH and placebo (2 weeks each) combined with aripiprazole in children and adolescents (n = 16; 8-17 years old) with JBPD and ADHD who had a significant response in manic symptoms with aripiprazole but still presented clinically significant symptoms of ADHD. ADHD, manic, and depressive symptoms were assessed by means of standard scales. Fourteen out of the 16 subjects completed the trial. No significant differences between the effects of methylphenidate and placebo were detected in ADHD (F(1, 43.22) = 0.00; p = 0.97) or manic (F(1, 40.19) = 0.93; p = 0.34) symptoms. Significant improvement in depressive symptoms was observed in the MPH group (F(1,19.03) = 7.75; p = 0.01) according to a secondary self-reported outcome measure. One patient using aripiprazole and MPH discontinued the trial due to the onset of a severe mixed episode. No other significant adverse events were observed. Although MPH did not worsen manic symptoms, it was not more effective than placebo in improving ADHD symptoms in children and adolescents with JBPD co-morbid with ADHD stabilized with aripiprazole. Further investigations are warranted. This study is registered at www.clinicaltrials.gov under the identifier NCT00305370.

Pesquisa em psiquiatria da infância e da adolescência / Research on child and adolescennt psychiatry

A presente revisão busca avaliar criticamente: a) a situação da pesquisa em psiquiatria da infância e da adolescência nos EUA e no Brasil; b) as razões do desinteresse do psiquiatra de crianças e adolescentes em pesquisas e, mais ainda, nos resultados de pesquisa; c) as áreas de pesquisa em Psiquiatria da Infância e da adolescência e suas dificuldades; d) questões éticas de pesquisa nesse campo.

Transtorno de déficit de atenção/hiperatividade: revisando conhecimentos / Attention deficit hyperactivity disorder: an update

Tem-se dado crescente importância ao Transtorno de déficit de atenção/hiperatividade (TDAH), visto que ele associa-se com comorbidades importantes, bem como com uma maior frequência de desfechos relevantes, tais como déficit de funcionamento acadêmico e social ao longo do ciclo de vida do indivíduo. Recentemente, inúmeras pesquisas têm demonstrado que o transtorno ultrapassa os limites da infância, sendo prevalente em adolescente e mesmo em adultos. Esta é uma revisão atual e crítica dos principais aspectos do histórico, epidemiologia, etiologia, quadro clínico, comorbidades, diagnóstico, evolução e tratamento do transtorno
