![]() 1 A structured clinical interview was conducted with parents and school teachers through SNAP IV 11 and Conners Rating Scales Revised. ![]() ADHD: Attention Deficit and Hyperactivity Disorder DSM-IV: Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition SNAP-IV (Swanson et al., 2001) MPH: Methylphenidate (0.5 mg/kg/day) SN: speech with white noise DD: dichotic digits PPS: pitch pattern sequence.Īfter written informed consent has been signed, children, parents (or caregivers), and teachers underwent a diagnostic assessment for ADHD and subtypes, using Portuguese versions of DSM-IV-TR criteria. The study examined the AP in ADHD children compared with non-ADHD children, and before and after 3 or 6 months of methylphenidate (MPH) treatment in ADHD children.įlow chart of the general experimental protocol. Our hypothesis was that ADHD children would present deficits in the discrimination of noise environmental, of temporal processing, and of auditory attention, when compared with non-ADHD children, and that these deficits would improve along 6 months of MPH treatment. To better understand this issue, we proposed analyzing the auditory processing, through a behavioral auditory battery, in ADHD children before and after MPH treatment. 8 However, MPH effect data on the auditory processing in ADHD children are scarce. 9 According to Ozdag et al, 10 MPH may improve the deficits of auditory information processing in ADHD children with no influence over information inputs. 8 Stimulant drugs, such as methylphenidate (MPH), are the standard pharmacological treatment for ADHD. 7 Although APD and ADHD have overlapping clinical characteristics, they are distinct entities, requiring accurate diagnoses and appropriate interventions. Recently, studies have suggested that ADHD children show sensory processing deficits, in which the underlying pathophysiology is poorly understood. 5 Disorders such as ADHD, autism, and learning disabilities may present similar symptoms. APD children may have difficulties hearing in noisy environments, understanding instructions, 4 reading, and spelling, as well as poor concentration and impaired memory. 4Īuditory Processing Disorder (APD) refers to auditory perceptual difficulties that are not related to peripheral hearing deficits or language and cognitive dysfunctions. ![]() 3Īuditory Processing (AP) refers to the perceptual processing of auditory information in the Central Nervous System (CNS), including sound localization, auditory discrimination, auditory pattern recognition, temporal aspects of hearing during exposure to competitive, and degraded acoustic signs. 1 It is the most common psychiatry disorder with 5.3% prevalence in school children population 2 and high association with comorbidities, such as Oppositional Defiant Disorder (ODD). ![]() Treatment with MPH gradually improved these deficiencies and completely reversed them by reaching a performance similar to non-ADHD children at 6 months of treatment.Īttention Deficit Hyperactivity Disorder (ADHD) is a neurobiological condition characterized by symptoms of inattention, hyperactive, and impulsive behaviors. The treatment with MPH, especially along 6 months, significantly decreased the mean errors in the DD ( p < 0.01) and increased the correct response in the PPS ( p < 0.001) and SN ( p < 0.01) tests when compared with the performance before MPH treatment.Ĭonclusions ADHD children show inefficient AP in selected behavioral auditory battery suggesting impaired in auditory closure, binaural integration, and temporal ordering. Results ADHD children presented larger number of errors in DD ( p < 0.01), and less correct responses in the PPS ( p < 0.0001) and in the SN ( p < 0.05) tests when compared with non-ADHD children. They were followed for 3 and 6 months of MPH treatment (0.5 mg/kg/day). They were submitted to a behavioral battery of AP tests comprising Speech with white Noise, Dichotic Digits (DD), and Pitch Pattern Sequence (PPS) and were compared with non-ADHD children. Methods Drug-naive children diagnosed with ADHD combined subtype aging between 7 and 11 years, coming from public and private outpatient service or public and private school, and age-gender-matched non-ADHD children, participated in an open, non-randomized study from February 2013 to December 2013. Objective The study examined the AP in ADHD children compared with non-ADHD children, and before and after 3 and 6 months of methylphenidate (MPH) treatment in ADHD children. Introduction Children with Attention Deficit Hyperactivity Disorder can present Auditory Processing (AP) Disorder. ![]()
