Beyin harekete geçirmek (NIR-HEG/Q-EEG) ve yürütme önlemler (CPTs) bir DEHB değerlendirme protokolü kullanarak

Overview

This study introduces a comprehensive protocol for diagnosing Attention Deficit Hyperactivity Disorder (ADHD), emphasizing more objective measurement through innovative assessment tools. It explores the connection between cortical activation and executive function, addressing how different brain areas relate to ADHD symptoms.

Key Study Components

Area of Science

• Neuroscience
• Clinical Psychology
• Diagnostic Assessment

Background

• ADHD is characterized by persistent patterns of inattention, hyperactivity, and impulsivity.
• The Diagnostic and Statistical Manual (DSM-IV) outlines three types of ADHD presentations.
• Dysfunction in dopaminergic and androgenic systems underpin ADHD symptoms.
• Current diagnostic methods lack a unified protocol, making assessment challenging.

Purpose of Study

• To present a model for a more objective ADHD diagnostic procedure.
• To investigate relationships between brain activation and executive function.
• To identify cortical activation patterns associated with ADHD symptoms.

Methods Used

• The study utilizes continuous performance tests (CPTs) to assess attention and impulsivity.
• Key assessments include the traditional Test of Variables of Attention and the virtual reality-based Aula Nesplora.
• Cortical activation is measured using hemoencephalography and quantified electroencephalogram.
• Testing involves multiple phases, immersing participants in interactive tasks within a virtual classroom environment.
• Participants engage in a 20-minute Aula Nesplora test with different executive function paradigms.

Main Results

• Unique activation patterns correlated with different executive function tasks in ADHD diagnoses.
• The methodology provides a framework to improve ADHD assessment accuracy.
• Key measures of attention, impulsivity, and performance speed were effectively captured through both CPTs.

Conclusions

• This study enhances the diagnostic potential for ADHD by introducing a structured protocol incorporating technological advancements.
• The findings underline the significance of cortical activity in understanding ADHD's behavioral manifestations.
• This research has implications for improving intervention strategies and contributes to the knowledge of ADHD's neurobiological underpinnings.
