AIMS: Children with attention deficit hyperactivity disorder (ADHD) often present with deficits in fine motor control. The cortico-spinal tract (CST) is critical for voluntary motor control. Although neuroimaging work has identified anomalous microstructural properties in the CST in ADHD, no study to date has attempted to investigate the link between deficits in fine motor performance and microstructural properties of the CST in children with ADHD. This study aimed to address this gap using a novel fixel-based analysis (FBA). METHODS: Participants were 50 right-handed medication naïve children with a history of ADHD and 56 non-ADHD controls aged 9-11 years. Fine motor control was assessed us..View full abstract
