Differences in motor imagery between children with developmental coordination disorder with and without the combined type of ADHD.

Full Abstract

It has been proposed, and questioned, whether motor impairments in attention-deficit-hyperactivity disorder, combined type (ADHD-C) alone, developmental coordination disorder (DCD) alone, and ADHD-C and comorbid DCD (ADHD-C/DCD) may arise from disruption to a common set of cognitive functions and their related neural substrate. This study examined movement durations for real and imagined movements in a visually guided pointing task in 58 prepubertal children aged 8 to 12 years old with ADHD-C alone (n=14), ADHD-C/DCD (n=14), DCD alone (n=15), and an age-, sex-, and Full-scale IQ-matched healthy comparison group (n=15). There were 10 males and 4 or 5 females in each group. The DCD alone group demonstrated an inability to generate imagined movements that was not present in the ADHD-C group, with or without comorbid DCD, or healthy comparison participants. These findings add to the emerging literature characterizing intended and actual motor impairments associated with DCD alone.
