Abstract

This study aims to determine whether children with ADHD and learning disabilities (LD) have a significant history of obstetrical complications when compared to children with ADHD but without LD. Methods: Sixty-four children aged 6 to 12 years diagnosed with ADHD were assessed for a history of obstetrical complications using the Kinney medical and gynecological questionnaire. Learning ability was appraised using the Wide-Range Achievement Test (WRAT-R) for anglophone students and the "Test de Rendement Français" for francophone students. Results: Children with ADHD and a learning disability in mathematics had a higher rate of neonatal complications of great severity (p = 0.01) than children with ADHD and no disability in mathematics. Children with ADHD and a learning disability in reading also had a preponderance of neonatal complications of high severity (p = 0.02) compared to their peers with ADHD and no learning disability in reading. Children with ADHD and learning disability tend to have a significant history of neonatal complications, which validates the theory that complications in early life could adversely affect a child's academic ability later in life. This further confirms the importance of the perinatal and postnatal periods in CNS development of brain regions essential for mathematics and reading ability.
