Using Mobile Electroencephalography and Actigraphy to Diagnose Attention-Deficit/Hyperactivity Disorder: Case-Control...

Area of Science:

• Neuroscience
• Pediatrics
• Psychiatry

Background:

• Attention-deficit/hyperactivity disorder (ADHD) is a neurobehavioral disorder impacting children's learning and social relationships.
• Current diagnostic tools in psychiatric clinics aid in evaluating ADHD and determining treatment needs.
• Objective assessment methods are crucial for accurate ADHD diagnosis and management.

Purpose of the Study:

• To evaluate electroencephalography (EEG) and actigraphy for ADHD diagnosis.
• To identify and validate indicators of attention, meditation (EEG), and activity (actigraph) for ADHD.
• To compare the efficacy of EEG and actigraphy in ADHD screening.

Main Methods:

• Recruited 63 participants (53 with ADHD, 10 controls), age-matched.
• Utilized a 20-minute testing protocol divided into pretest, in-test, and posttest stages.
• Employed correlation analysis, repeated measures ANOVA, and regression analysis for indicator validation.

Main Results:

• EEG attention indicators showed significant correlations with reaction time and standard error changes.
• Actigraphy indicators (confidence index, omissions, RT SE, variability) were significant predictors of ADHD.
• Actigraphy demonstrated superior performance over EEG in screening for ADHD, with significant differences in activity levels observed in ADHD participants (P<0.001).

Conclusions:

• Increased activity levels in ADHD individuals under specific conditions may serve as a novel electronic physiological biomarker.
• Actigraphy effectively quantifies activity levels, aiding physicians in objective ADHD diagnosis.
• Development of rapid, objective auxiliary diagnostic tools for ADHD is supported by these findings.
