Do Children with ADHD Have Higher RLS Rates? 

Yes, research indicates that RLS rates in children with ADHD are significantly higher compared to children without ADHD. Restless legs syndrome (RLS) is a neurological condition that causes an uncontrollable urge to move the legs, often accompanied by uncomfortable sensations. These symptoms typically worsen in the evening or at night, disrupting sleep and affecting daytime functioning. 

The Link Between Pediatric RLS and ADHD 

Studies have found that pediatric RLS is more prevalent among children diagnosed with ADHD, with some research suggesting rates up to twice as high as in the general paediatric population. Both conditions are thought to involve irregularities in dopamine regulation, a neurotransmitter crucial for controlling movement, attention, and motivation. Iron deficiency, another factor linked to RLS, has also been reported more often in children with ADHD. 

Impact on ADHD Symptoms 

When children experience poor sleep due to RLS, their ADHD comorbidity symptoms, such as inattention, hyperactivity, and impulsivity, may become more pronounced. This can make school performance, emotional regulation, and daily routines even more challenging. 

Why Early Recognition Matters 

Identifying RLS in children with ADHD is crucial because targeted treatment, such as addressing iron deficiency, improving sleep hygiene, or using dopamine-based medications, can improve both sleep quality and ADHD symptom control. Without intervention, the cycle of poor sleep and worsened ADHD behaviours can persist. 

Understanding the higher RLS rates of children with ADHD can help parents, teachers, and healthcare providers take a proactive approach to diagnosis and treatment. For more on pediatric RLS and managing ADHD comorbidity, consider reaching out to providers like ADHD Certify.
