Subtle Motor Signs as a Biomarker for Mindful Movement Intervention in Children with Attention-Deficit/Hyperactivity Disorder.

ABSTRACT:

Objective

Previous studies of Tai Chi or mindfulness-based interventions in attention-deficit/hyperactivity disorder (ADHD) have relied on self- or parent-reported outcome measures; however, there is a critical need for the validation of objective biomarkers of treatment. Therefore, we implemented a mindful movement intervention for children with ADHD, hypothesizing that an ADHD-relevant motor control measure could serve as a predictive biomarker of treatment-related improvement.

Methods

Thirty-four participants were included, 8 to 12 year olds diagnosed with DSM-5 ADHD. Participants engaged in the mindful movement treatment, an 8-week program with 2 classes a week for 60 minutes. At pre- and post-treatment, ADHD symptoms and associated impairment and motor control via the Physical and Neurological Examination for Subtle Signs (PANESS) were assessed.

Results

The results showed a significant reduction for PANESS Gaits and Station (p ≤ 0.001), total overflow (p = 0.009), and total score (p = 0.001) after treatment, with the largest effect for Gaits and Stations. The results also showed a significant reduction in symptoms of inattention (p ≤ 0.001), hyperactivity/impulsivity (p ≤ 0.001), oppositional defiant disorder (p = 0.001), and executive dysfunction (p ≤ 0.001). There were significant positive correlations between change in PANESS Gaits and Stations and change in both inattentive (p = 0.02) and hyperactive/impulsive symptoms (p = 0.02). There was also a significant positive correlation between change in the PANESS total score and change in inattentive (p = 0.007) and hyperactive/impulsive symptoms (p = 0.042). The change in the PANESS total score (β = 0.295, p = 0.002) predicted post-treatment ADHD severity above the change in inattentive or hyperactive/impulsive symptoms.

Conclusion

The results suggest the effectiveness of a mindful movement treatment on ADHD symptoms and suggest the PANESS as a candidate motor biomarker for future mindful movement trials.

Project description:ImportanceMotor vehicle crashes (MVCs) are a major public health problem. Research has demonstrated that individuals with attention-deficit/hyperactivity disorder (ADHD) are more likely to experience MVCs, but the effect of ADHD medication treatment on the risk of MVCs remains unclear.ObjectiveTo explore associations between ADHD medication use and risk of MVCs in a large cohort of patients with ADHD.Design, setting, and participantsFor this study, a US national cohort of patients with ADHD (n = 2 319 450) was identified from commercial health insurance claims between January 1, 2005, and December 31, 2014, and followed up for emergency department visits for MVCs. The study used within-individual analyses to compare the risk of MVCs during months in which patients received ADHD medication with the risk of MVCs during months in which they did not receive ADHD medication.ExposuresDispensed prescription of ADHD medications.Main outcomes and measuresEmergency department visits for MVCs.ResultsAmong 2 319 450 patients identified with ADHD, the mean (SD) age was 32.5 (12.8) years, and 51.7% were female. In the within-individual analyses, male patients with ADHD had a 38% (odds ratio, 0.62; 95% CI, 0.56-0.67) lower risk of MVCs in months when receiving ADHD medication compared with months when not receiving medication, and female patients had a 42% (odds ratio, 0.58; 95% CI, 0.53-0.62) lower risk of MVCs in months when receiving ADHD medication. Similar reductions were found across all age groups, across multiple sensitivity analyses, and when considering the long-term association between ADHD medication use and MVCs. Estimates of the population-attributable fraction suggested that up to 22.1% of the MVCs in patients with ADHD could have been avoided if they had received medication during the entire follow-up.Conclusions and relevanceAmong patients with ADHD, rates of MVCs were lower during periods when they received ADHD medication. Considering the high prevalence of ADHD and its association with MVCs, these findings warrant attention to this prevalent and preventable cause of mortality and morbidity.
