Summary
Research consistently finds that children with ADHD have lower HRV than neurotypical peers, suggesting autonomic nervous system involvement in ADHD. This may explain difficulties with emotional regulation and attention.
Methods
Multi-parametric study and meta-analysis of ADHD and HRV
Key Findings
- Children with ADHD show 15-25% lower RMSSD than controls
- Reduced parasympathetic activity during rest and tasks
- HRV differences correlate with symptom severity
- Some stimulant medications may improve HRV
- HRV biofeedback being explored as adjunct treatment
Limitations
Medication effects complicate interpretation, varied age ranges
What This Means for You
If your child has ADHD and you're tracking their HRV, expect lower values than age-matched norms. Focus on their personal trends rather than population comparisons. HRV biofeedback may be worth exploring.
