Abstract

Introduction: Electroencephalogram (EEG) through event-related potential (ERP) of P50 has been widely used to measure sensory gating. However, this method of assessment is not always available. Considering the importance of sensory gating, this study aimed to investigate the potential use of ABR test with Stroop Task as an alternative method to objectively measure sensory gating, particularly among APD children. Methods: This study was conducted among 79 normal hearing children, aged from 8 to 12 years old. The children were divided into normal and APD group and were further categorized based on their attention status that was assessed through the SNAP-IV questionnaire, which are; i) normal attention; ii) attention deficit disorder (ADD) and iii) attention deficit hyperactivity disorder (ADHD). ABR test was conducted concurrently with Stroop Task that produce cognitive interference. The difference in wave V amplitude and latency between ABR recording with incongruent and neutral Stroop condition were calculated. Results: In normal children, significant reduction in wave V amplitude was observed during ABR recording with incongruent Stroop condition compared to neutral Stroop condition. Oppositely, in APD children, the wave V amplitude of ABR recording with incongruent Stroop condition was higher than neutral Stroop condition. This increment in wave V amplitude was more pronounce among APD children with attention deficit. No significant changes were observed in wave V latency. Discussion: Due to increase in cognitive interference during incongruent Stroop condition, the acoustic stimuli presented during ABR test were considered as irrelevant and suppressed, which lead to reduction in wave V amplitude. However, no reduction in wave V amplitude was observed among APD children, which possibly demonstrate lack of suppression and inhibitory control. The difference in the effect of increase in cognitive interference between normal and APD children indicates the potential use of ABR with Stroop Task as an alternative method to measure sensory gating.
