Key result
Children with ADHD exhibited increased parasympathetic activity compared to controls, with higher differences between adjacent normal-to-normal intervals >50 ms (199.75 vs 127.46; P<0.05).
Why the study?
Does cardiac autonomic modulation, measured by heart rate variability, differ in children with attention deficit hyperactivity disorder compared to healthy controls?
Case-Control (n=56)

Absolute Event Rate: 199.75% vs 127.46%
p-value: p=<0.05
Children with ADHD demonstrate increased parasympathetic autonomic nervous system activity compared to healthy controls, as evidenced by heart rate variability analysis.
No takes yet. Share an insight, caveat, or question.
Increased parasympathetic activity in ADHD children should not yet change practice; leaves open longitudinal HRV studies on cardiac outcomes.
Abreu et al. (2014) conducted a case-control in Attention deficit hyperactivity disorder (ADHD) (n=56). Attention deficit hyperactivity disorder (ADHD) vs. Controls without ADHD was evaluated on Differences between adjacent normal-to-normal intervals greater than 50 milliseconds (p=<0.05). Children with ADHD exhibited increased parasympathetic activity compared to controls, with higher differences between adjacent normal-to-normal intervals >50 ms (199.75 vs 127.46; P<0.05).
