Purpose:To characterize the behavioral signs of attention deficit hyperactivity disorder (ADHD) and central auditory processing disorder (CAPD) from the perspective of the professionals who diagnose and manage these conditions in Brazil. Methods: Forty-two health professionals in Brazil (medical doctors, speech therapists, psychologists, and pedagogues) participated in this study, and they responded to a questionnaire listing 58 behavioral signs of ADHD and CAPD. The participants were asked to score the listed behavioral signs according to the frequency with which they occurred, from 1 (never) to 5 (always). The average values were compared to the results of a similar study conducted in North America. Results: Some of the listed behavioral signs were indicated more often than others, depending on the disorder. In the case of ADHD, the behavioral signs most often mentioned were difficulty playing quietly, distraction, disorganization, inattentiveness, hyperactivity, restlessness, shifting from one incomplete task to another, poor self-control, lack of persistence, and hastiness or impulsiveness. The most evident behavioral signs of CAPD were auditory divided attention deficit, auditory selective attention deficit, difficulty following instructions given orally, poor auditory association skills, difficulty hearing in a noisy environment, auditory sustained attention deficit, difficulty discriminating speech, and reduced auditory information processing rate. Conclusion: The health professionals identified some behavioral signs as being more evident in ADHD and other signs as more evident in CAPD. RESUMO Objetivo: Caracterizar os sinais comportamentais do Transtorno do Déficit de Atenção com Hiperatividade (TDAH) e do Transtorno do Processamento Auditivo (TPA), segundo a visão de profissionais que atuam no diagnóstico e intervenção relacionados a estes transtornos no Brasil. Métodos: Participaram 42 profissionais (médicos, fonoaudiólogos, psicólogos e pedagogos). Todos responderam a um questionário contendo 58 sinais comportamentais de TDAH e TPA. Cada participante foi orientado a classificar os comportamentos de acordo com a frequência de ocorrência, elencando-os em categorias de 1 (nunca) a 5 (sempre). Os valores da média geral deste estudo foram comparados aos valores da média apresentados em estudo norte americano similar. Resultados: Verificou-se que alguns sinais comportamentais foram mais citados do que outros em ambos os transtornos. No TDAH os sinais comportamentais mais evidentes foram: dificuldade em brincar silenciosamente, distraído, desorganizado, desatento, hiperativo, irrequieto, muda de um trabalho incompleto para o outro, pouco autocontrole, falta de persistência e apressado ou impulsivo. No TPA os sinais comportamentais mais evidentes foram: déficit na atenção auditiva dividida, déficit na atenção auditiva seletiva, dificuldade em seguir instruções orais, habilidade de associação auditiva ruim, dificuldade de ouvir em ambiente ruidoso, déficit na atenção auditiva sustentada, dificuldade em discrimi...

A ttention deficit hyperactivity disorder (ADHD) patients show, as one of the main symptoms, an attentional impairment. Selective attention in the hearing process is the ability to understand speech in a noisy environment, which can be evaluated by several methods. One of the main approaches is the functioning of the Medial Olivocochlear Efferent System, which can be accessed by TransientEvoked Otoacoustic Emissions (TOAE).Objective: This study aimed at evaluating the suppression effect of contralateral noise on TOAE in ADHD (study group) and normal subjects (control group). Study Design: Case-control study. Material and Methods:A study with 20 children distributed in two, age-and gender-matched groups. Results: No differences were found in TOAE responses between the two groups, with and without noise. Conclusions:We conclude that there were no functional differences in the Medial Olivocochlear Efferent System in the two groups analyzed. Braz J Otorhinolaryngol. 2012;78(3):27-31. ORIGINAL ARTICLE
