Developmental brain trajectories in children with ADHD and controls: a longitudinal neuroimaging study

Area of Science:

• Neuroscience
• Developmental Psychology
• Child Psychiatry

Background:

• Attention Deficit/Hyperactivity Disorder (ADHD) symptoms and cognitive function evolve during adolescence.
• The relationship between brain development trajectories and ADHD outcomes remains unclear.
• Understanding these changes is crucial for predicting ADHD course and informing interventions.

Purpose of the Study:

• To investigate how brain structure and function change with age in children with ADHD.
• To determine if distinct brain development trajectories are linked to variations in ADHD outcomes.
• To explore the influence of sex, ADHD presentation, comorbidities, and medication on brain development.

Main Methods:

• The Neuroimaging of the Children's Attention Project (NICAP) is a longitudinal, multimodal neuroimaging study.
• Approximately 200 children (100 with ADHD, 100 controls) aged 9-11 years are scanned at 18-month intervals.
• Magnetic resonance imaging (MRI) is used alongside diagnostic interviews, questionnaires, and cognitive assessments.

Main Results:

• Data collection is ongoing; results are pending.
• Analysis will focus on changes in brain structure and function over time.
• Correlations between neuroimaging findings and clinical/behavioral outcomes will be examined.

Conclusions:

• NICAP aims to describe the neurobiological development of ADHD.
• The study will identify brain features associated with differential clinical and behavioral outcomes.
• Findings may improve prediction of ADHD course and inform personalized treatment strategies.
