The study highlights the need for improved access to behavioral therapy for children with ADHD.
A new study found that children and teens with ADHD lag behind others in forming connections within their brains, particularly between networks controlling internal and external tasks. This lag may contribute to the disorder's hallmark symptoms of distraction and difficulty focusing.
A new study from Michigan State University and University of Vermont researchers found that daily before-school aerobic activities can help reduce ADHD symptoms in elementary school students. Children with a higher risk of ADHD showed significant improvements across various outcomes compared to those receiving sedentary activities.
Researchers found that ADHD children use less differentiated learning patterns, leading to suboptimal decisions. The study used mathematical models and multimodal imaging to examine brain activity in participants with and without ADHD.

These dimensions are linked to externalizing problems and can be targeted in interventions. The study suggests prevention and intervention approaches targeting these deficits have potential to impact clinical outcomes.
Researchers found that medication treatment for ADHD improved parenting skills in adults, leading to reduced negative child behavior and improved parenting practices. Parents who received lisdexamfetamine showed fewer commands, more responsive interactions, and increased praise compared to those on placebo.
Researchers found that levels of severity and functional impairment among children with ADHD under 7 were comparable to those with other mental disorders. The study highlights the importance of systematic study of diagnostic criteria in representative samples.
A new study found that people are more accepting of using performance-enhancing products for personal gain than for athletic performance. The research suggests that brands can make their products more appealing by reframing their effects as enabling true abilities rather than embellishing beyond them.
A Swedish study using national patient registers found no link between ADHD drug treatment and increased risk of suicide attempts or suicide. Instead, researchers suggest that ADHD medications may have a protective effect against suicidal behaviors.
Researchers have identified abnormal brain iron levels in children and adolescents with Attention Deficit Hyperactivity Disorder (ADHD), which may help improve diagnosis and treatment. The study suggests that brain iron absorption into the brain is abnormal in ADHD, even when blood iron levels are normal.
Researchers discovered distinct patterns of brain activity in adults with and without childhood ADHD, finding that those who recovered from the disorder have restored normal synchrony in their brain's default mode network. However, both groups showed impaired executive function, a sign separate from ADHD.
