The Clinical Utility of the Objective Measures for Diagnosing and Monitoring Attention-Deficit and Hyperactivity Disorder (ADHD) in Adults: A Systematic Review
Bibliographic record
Abstract
Background: Clinical practice suggests that objective assessment tools are needed to assess adults with inattention or hyperactivity, informed by the underlying pathophysiology of attention-deficit and hyperactivity disorder (ADHD). This systematic review comprehensively evaluates the current objective assessment methods as an adjunct diagnostic tool for these adults. Methods: We conducted a systematic review of studies investigating various objective diagnostic methods to assess adults with ADHD and healthy controls. The database search occurred from its inception to 23 December 2024. Results: Our search yielded 46 studies that reported on various objective methods to assess adults with ADHD. The MOXO-distracted Continuous Performance Test (MOXO-d-CPT), eye-tracker with MOXO-d CPT, Conners’ Continuous Performance Test—3rd edition (CCPT-3), and oculomotricity can differentiate between true and feigned ADHD or other diagnostic possibilities. The Quantified Behavior Test (Qb Test+) can detect hyperactivity and differentiate it from other psychiatric disorders. Mono-d, CCPT-3, Qb Test+, Test of Variables and Attention (TOVA), Integrated Visual and Auditory Continuous Performance Test (IVA-CPT), and oculomotricity can monitor pharmacotherapy response. Functional near-infrared spectroscopy (fNIRS) offers more promise than structural imaging and demonstrates a moderate level of sensitivity and specificity to differentiate adults with and without ADHD by performing the verbal fluency test. Notwithstanding, electroencephalography (EEG)/event-related potential (ERP) shows potential in diagnosis and treatment monitoring (e.g., neurofeedback training). In addition, transcriptome-based biomarkers have also been explored as diagnostic tools. Conclusion: The diagnosis and monitoring of ADHD in adults come with a unique set of challenges due to psychiatric comorbidity, including depression and anxiety; fluctuation of symptoms over time; and lack of consensus among clinicians and professional organizations to adopt objective tests in the diagnostic process. Our findings support the notion that a combination of clinical assessment and objective biomarkers targeting distinct pathophysiological aspects may enhance the accuracy of ADHD diagnosis.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
