Clinical Characteristics in Attention-Deficit Hyperactivity Disorder with/or without Developmental Coordination Disorder Patients

ABSTRACT

OBJECTIVES: This study explored the clinical differences in attention-deficit hyperactivity disorder (ADHD) patients with and without developmental coordination disorder (DCD). METHODS: Participants were 49 children and adolescents with ages between 6 and 18 years. These subjects were placed into 2 groups ADHD without DCD (24) and ADHD with DCD (25). We used several evaluation tools on both groups the Affective Disorders and Schizophrenia-Present and Lifetime Version- Korean Version (K-SADS-PL), Wechsler Intelligence Scale for Children-III (WISC-IIII), Child Behavior Check List (CBCL), Korean Personality Rating Scale for Children (K-PRC), and Bruininks-Osretsky Test of Motor (BOT-2). RESULTS: Patients with both ADHD and DCD had a lower performance intelligence quotient and more internal and external behavioral symptoms than patients with ADHD but not DCD. It is possible that patients with ADHD and motor coordination problems should be noticed earlier and given intensive treatment.
