Area of Science:

  • Developmental psychology
  • Neuroscience
  • Educational psychology

Background:

  • Developmental dyscalculia is a primary cognitive disorder affecting mathematical abilities.
  • Understanding its prevalence and associated factors is crucial for early intervention.

Purpose of the Study:

  • To determine the prevalence and demographic features of developmental dyscalculia in 11-year-old children.
  • To investigate associated factors including IQ, ADHD, dyslexia, socioeconomic status, and family history.

Main Methods:

  • A cohort of 3029 students was screened, with 143 identified with developmental dyscalculia.
  • Evaluations included assessments of gender, IQ, linguistic and perceptual skills, ADHD symptoms, socioeconomic status, and learning disabilities.
  • IQ scores ranged from 80-129 (mean 98.2).

Main Results:

  • The prevalence of dyscalculia was 6.5%, comparable to dyslexia and ADHD.
  • 26% of children with dyscalculia exhibited ADHD symptoms, and 17% had dyslexia.
  • Children with dyscalculia had lower socioeconomic status and 42% had learning disabilities in first-degree relatives.
  • Dyscalculia affected boys and girls equally.

Conclusions:

  • Developmental dyscalculia has a significant prevalence in school-aged children.
  • It frequently co-occurs with ADHD and dyslexia and is linked to socioeconomic factors.
  • Unlike other learning disabilities, dyscalculia shows no significant gender disparity.
