Learning disabilities: Developmental dyscalculia
2020Developmental dyscalculia (DD) is a developmental learning disability that manifests as a persistent difficulty in comprehending even the most basic numeric and arithmetic concepts, despite normal intelligence and schooling opportunities. Given the predominant use of numbers in modern society, this condition can pose major challenges in the sufferer's ...

Patterns of Developmental Dyscalculia With or Without Dyslexia
Neurocase, 2007This study has been conducted in order to investigate the extent to which some characteristics of dyscalculia may be common to dyslexia. Seven multiple single-cases were studied: two children with dyslexia only, two with dyscalculia only, and three more children with comorbidity of dyslexia and dyscalculia.

Number development and developmental dyscalculia
Developmental Medicine & Child Neurology, 2007There is a growing consensus that the neuropsychological underpinnings of developmental dyscalculia (DD) are a genetically determined disorder of ‘number sense’, a term denoting the ability to represent and manipulate numerical magnitude nonverbally on an internal number line.

Developmental Dyscalculia and Medical Assessment
Journal of Learning Disabilities, 1993Developmental dyscalculia (DC) is a primary cognitive disorder of childhood manifested by disturbance of arithmetic ability. As an isolated learning disability (LD), it is usually treated by remedial education and not referred for further medical evaluation.

Developmental Dyscalculia and Brain Laterality
Cortex, 1995The correlation between arithmetic dysfunction and brain laterality was studied in 25 children with developmental dyscalculia (DD). The children were tested on a standardized arithmetic battery and underwent a neurological and neuro-psychological evaluation.

DEVELOPMENTAL DYSCALCULIA: PREVALENCE AND DEMOGRAPHIC FEATURES
Developmental Medicine & Child Neurology, 1996SUMMARYOne hundred and forty‐thrée 11‐year‐old children with developmental dyscalculia, from a cohort of 3029 students, were studied to determine demographic features and prevalence of this primary cognitive disorder. They were evaluated for gender, IQ, linguistic and perceptual skills, symptoms of attention‐deficit hyperactivity disorder (ADHD), socio‐

Conceptual size in developmental dyscalculia and dyslexia.
Neuropsychology, 2018People suffering from developmental dyscalculia (DD) are known to have impairment in numerical abilities and have been found to have weaker processing of countable magnitudes. However, not much research was done on their abilities to process noncountable magnitudes.

Inhibitory ability of children with developmental dyscalculia
Journal of Huazhong University of Science and Technology [Medical Sciences], 2011Inhibitory ability of children with developmental dyscalculia (DD) was investigated to explore the cognitive mechanism underlying DD. According to the definition of developmental dyscalculia, 19 children with DD-only and 10 children with DD&RD (DD combined with reading disability) were selected step by step, children in two control groups were matched ...
