A estimativa do tempo modifica o comportamento cognitivo e cortical de adultos com transtorno de déficit de atenção e hiperatividade

Abstract

Attention deficit hyperactivity disorder (adhd) is a neurological disorder characterized by levels of inattention, hyperactivity, and impulsivity, which affect time subjective perception. However, it is not clear whether time estimation tasks application induces changes in adhd subjects' time perception. Aim: this study investigated whether time estimation task training influences on adhd subjects' classification levels, as well as theta band activity changes in the dorsolateral prefrontal cortex and ventrolateral prefrontal cortex. Materials and methods: fourteen adhd subjects participated in this study under control conditions (without time estimation training) and experimental (thirty days of time estimation Training) with concomitant electroencephalographic analysis. Adhd scale adolescents and adults version was used to verify adhd levels and classification. Results and discussion: subjects who performed the training presented better task performance (p <0.05) with cognitive aspects improvement (attention, impulsivity, and emotion) (p <0.05). Electrophysiological results show that training increases activity in dorsolateral prefrontal cortex and ventrolateral prefrontal bilaterally (p <0.001). Conclusion: time estimation task training improves adhd cognitive symptoms, with a substantial increase in cortical areas activity related to attention and memory, being a tool for timing cognitive management and for non-invasive therapeutic aid in ADHD.
