Habilidades auditivas em crian？as com dislexia e transtorno do déficit de aten？？o e hiperatividade

background: auditory processing and co-occurrence of pathologies. aim: to investigate the performance of children with dyslexia and attention deficit hyperactivity disorder (adhd) in behavioral and auditory processing tests, comparing the results to a control group. method: participants of the study were 30 children, with ages between 7 and 12 years, divided into three groups: a control group of 10 children, a study group of 10 children with dyslexia and a study group of 10 children with adhd. all participants were submitted to the following auditory processing tests: speech in noise, dichotic of digits and frequency pattern. results: concerning the speech in noise test, there was an interactive effect between the control group and the adhd group (p < 0.001), with the adhd group presenting a significantly lower performance; for the dichotic of digits test, there was an interactive effect between the three groups (p < 0.001), with the adhd group presenting a lower performance, followed by the dyslexic and control groups; for the frequency pattern, there was a marginal effect (p = 0.056) with the adha group presenting a lower performance, followed by the dyslexic and control groups. conclusion: the adhd group presented a poorer performance in all tests when compared to the dyslexic and control groups. this result suggests a relationship between attention and hearing abilities.
