“…Our study corroborates the aforementioned study, as there was no significant difference for the finding as to latency. In the literature there was also the rare stimulus counting in two ways namely: counting mentally 27 , counting mentally and raising the hand 21,26,28 to hear it and after, count aloud 21,29 .…”

Purpose: to identify if there are differences in the findings of Long Latency Auditory Evoked Potencial for latency and amplitude in different ways of counting the rare stimulus, being mentally counting or marking on paper (without memorizing). Methods: this study was prospective and transversal. The sample consisted of convenience and comprised by 49 subjects, including 29 females and 20 males. The following procedures were performed: Visual inspection of the external auditory canal, pure tone audiometry, acoustic emittance measures and long latency auditory evoked potentials, which was performed twice, one after the other, with individuals paying attention to the rare stimulus, always starting counting mentally and after marking on a paper. Results: there were significant differences between the ears to the P1, P2 latencies and amplitude of N1 for the method of marking on paper and the amplitude of P2 in both methods but with all values within the range normality. In addition, a statistically significant difference was also evident when comparing genders, being found larger latency values of P2 and N2 for males in both counting methods of the rare stimuli. The amplitude of P1, P2 and P3 was lower in males in different ways to count, being in P2 the only difference in the method mentally counting. When comparing the methods, there was a statistically significant difference only to the latency of P2 which was higher values for the method of marking on paper. Conclusion: there were no differences for the latencies and amplitudes of the long latency potentials in comparison of the rare stimulus score (mentally counting and marking on paper) for almost all potentials except for the potential P2 regarding to amplitude and latency.

Métodos: esse estudo teve caráter prospectivo e transversal. A amostra foi composta por conveniência sendo constituída por 49 indivíduos, sendo 29 do gênero feminino e 20 do gênero masculino. Foram realizados os seguintes procedimentos: Inspeção Visual do Meato Acústico Externo, Audiometria Tonal Liminar, Medidas de Imitância Acústica e Potencial Evocado Auditivo de Longa Latência, o qual foi realizado duas vezes, uma após a outra, com os indivíduos atentando ao estímulo raro, começando sempre contando mentalmente e após marcando em um papel. Resultados: houve diferença estatisticamente significante entre as orelhas para as latências de P1, P2 e amplitude de N1 para o método de marcação no papel, da latência de N1 para o método de contagem mental dos estímulos raros, e da amplitude de P2 em ambos os métodos, porém com todos os valores dentro da faixa de normalidade. Além disso, a diferença estatisticamente significante também foi evidente na comparação entre os...

“…Also, snoring was found in 33% of children diagnosed as ADHD. Additionally, in one study, altered P300 in children with OSA was only found in children with severe OSA associated with sleep deprivation and forced awakeness, suggesting that the larger impact of OSA over P300 features may also be linked in young people 29 .…”

Objective To determine the prevalence of obstructive sleep apnea (OSA) in children with attention deficit/hyperactive disorder (ADHD) and compare amplitude and latency of the P300 potential among children with and without OSA. Method Sixty-one children with ADHD underwent oddball auditory attention tests for detection of P300 (ERPs) followed by an all-night polysomnography. The children were divided in two groups, those with and without OSA. Results Significant decreased amplitude of the P300 potential was observed in children with OSA when compared with children without OSA. Conclusion The study showed that sleep fragmentation as a result of OSA can exacerbate the attention disorder that characterizes ADHD, and highlights the importance of assessing the presence of OSA in the differential diagnosis of children with attention deficits.

“…The prevalence of OSAS ranges between 2% and 4% in the general population. Recurrent sleep disturbances cause increased daytime sleepiness, concentration difficulty, and impaired attention and learning (1). Hypoxic attacks have been shown to cause reduction in neurocognitive functions secondary to neuronal damage and atrophy at the brain cortex and hippocampus (2).…”

Background/aim: Obstructive sleep apnea syndrome (OSAS) is a disease characterized by repeated hypoxia attacks during sleep. The effect of hypoxia on the central nervous system is a well-known entity. In this study we aimed to investigate the effect of OSAS on the central auditory system. Materials and methods: Twenty-one OSAS patients diagnosed by polysomnography (PSG) and 10 control subjects were included in the study. After a thorough otorhinolaryngology examination, all subjects underwent pure tone audiometry (250 to 8000 Hz frequency). The subjects with normal otoscopic examination and hearing threshold were included in the study. All participants underwent speech discrimination analyses and auditory time processing and sequencing tests, i.e. frequency pattern test (FPT) and duration pattern test (DPT). Results: Although hearing was normal in the OSAS patients, significant loss was observed in the speech discrimination rates compared to the control group (P < 0.05). Significant disruption was also detected in the FPT and SPT in the OSAS patients (P < 0.05). Conclusion: Repeated hypoxic episodes in OSAS resulted in statistically significant impairments in the central auditory pathways, even if the hearing threshold was within normal limits.
