This paper examines the relationship between attention deficit hyperactivity disorder (ADHD) and learning disabilities (LD) in school-age children, drawing on a longitudinal study by Czamara et al. (2013) conducted over ten years with more than 4,000 children in Germany. The paper reviews evidence that ADHD and LD — particularly in reading, spelling, and math — are comorbid conditions likely rooted in a shared underlying cause. It discusses implications for educators and parents, stresses the importance of comprehensive diagnosis, and calls for further research into environmental, developmental, and lifestyle factors that may contribute to the co-occurrence of these conditions.
The article by Czamara, Tiesler, Kohlbock et al. (2013) focuses on attention deficit hyperactivity disorder (ADHD) and dyslexia as the most common neuro-behavioral childhood disorders. An estimated 5% of school-age children are affected by these conditions, while approximately half of all children with ADHD present as learning disabled (LD) students. The study examines the relationship between ADHD symptoms and learning disabilities in reading, spelling, and math. The researchers found that students with ADHD were at a higher risk of presenting with math, reading, and spelling learning disabilities compared to students without ADHD. The study demonstrated that both ADHD and learning disorders are comorbid and are likely the effect of the same underlying problem, though exactly what that problem or process is remains unclear.
Czamara et al. (2013) draw on numerous recent studies to support their research. These studies show that ADHD is often found among LD students and that there can be some confusion among teachers about the best way to approach these students — how to help them overcome learning obstacles and succeed in their schoolwork. However, few studies had actually compared the comorbidity of ADHD and LD, and as Czamara et al. (2013) note, the ultimate cause of this comorbidity remains unknown.
The study by Czamara et al. (2013) was a lengthy longitudinal investigation that took place over the course of ten years and included a population of more than 4,000 children in Germany. Questionnaires were distributed to families when children were 1, 2, 4, 6, and 10 years of age, and outcomes were measured according to the hyperactivity/inattention subscale of the Strengths and Difficulties Questionnaire (SDQ). Children without signs of ADHD were used as a reference category. Statistical analysis was conducted to interpret the nature of the results. Overall, the study supplied clear quantitative evidence of a strong correlation between ADHD and learning disorders.
