Motor Proficiency, Manual Dexterity, and Visual Perception in School-age Children With ADHD: Contribution of Different Comorbidities.

Attention-deficit/hyperactivity disorder (ADHD) is often comorbid with a number of other psychiatric conditions. The goal of this study was to investigate whether motor skills, manual dexterity, and visual perception differ in the presence of ADHD and comorbid psychiatric conditions in school-age boys by comparing them to a group of children with typical development (TD). We evaluated 81 boys 6 to 10 years of age in 5 groups: ADHD only (n=18); ADHD+specific learning disorders (ADHD+SLDs) (n=17); ADHD+oppositional defiant disorder (n=16); ADHD+anxiety disorders (n=15); and TD (n=15). The participants with ADHD only and those with ADHD+comorbidity had significantly lower scores than the participants in the TD group in every area we evaluated. The lowest scores were observed in the ADHD+SLD group in all motor skills domains except for the fine motor precision field. Furthermore, the group with ADHD+SLD had statistically significantly lower scores than the 3 other groups with ADHD+comorbidity in 3 areas: balance, upper extremity coordination, and speed and agility. Motor problems in patients with ADHD and comorbid conditions may not be a focus of attention in clinics. However, especially in the case of comorbid conditions accompanying ADHD, it is important to consider problems in motor skills, manual dexterity, and visual perception in evaluation and treatment to increase these children's quality of life.

[Motor Proficiency in Children with Attention Deficit Hyperactivity Disorder: Associations with Cognitive Skills and Symptom Severity]. / Dikkat Eksikligi Hiperaktivite Bozuklugu Olan Çocuklarda Motor Yeterlilik: Bilissel Beceriler ve Belirti Siddeti ile Iliskisi.

OBJECTIVES: Of children with Attention Deficit Hyperactivity Disorder (ADHD), 45-70% have motor skill problems, which can adversely affect social competence, peer relations, and academic skills. The aim of this study is to assess motor skills in school-aged children with ADHD, and to elucidate if there are any relationships between ADHD symptoms and cognitive function. METHOD: Included in this study were 58 children (38 ADHD, 20 controls) between 8-11 years of age. Children were diagnosed with ADHD via the Schedule for Affective Disorders and Schizophrenia for School-Aged Children Present and Lifetime Version. The parents were asked to fill out the Conner's' Parent Rating Scale - Revised Short Turkish Form to determine the symptom domains and the symptom severity. The Wechsler Children's Intelligence Scale-IV was used to assess cognitive skills, and the Bruininks -Oseretsky Motor Proficiency Test was used to assess motor skills. RESULTS: Children with ADHD had impaired performance in many motor skill areas compared to the controls. Impairments in fine motor skills were correlated with problems in attention, working memory, and processing speed. In the ADHD group, age was not correlated with motor skills enhancement. CONCLUSION: The multistage clinical evaluation of ADHD should include screening for problems in motor skills. If deficiencies are found, the child should be clinically evaluated for motor proficiency and, if necessary, should be referred for appropriate objective assessment and intervention programs.
