Dyscalculia

Dyscalculia is a math learning disability that impairs an individual’s ability to learn number-related concepts, perform accurate math calculations, reason and problem solve, and perform other basic math skills. 1. Dyscalculia is sometimes called “number dyslexia” or “math dyslexia.”

 

Cluster Number:
Wiki Number: W071
Diagnosis: Dyscalculia (Math Abilities)
US Patients: 3-6%
World Patients:
Sex Ratio:
Age Onset:
Brain Area: intraparietal sulcus, frontal lobe, and left angular gyrus; difficulty with spatial awareness and memory
Symptoms: math abilities may stop at the 4th grade level, that may also be a developmental delay
Progression: Limitations in memory, counting, doing math problems, avoidance of careers where math or science is a component
Causes:
Medications: transcranial direct durrent stimulation of the left parietal (anode) and right parietal lobe (cathode)improved math for 2.
Therapies: Several computerized training programs are listed in the Wikipedia article followed by the article’s bibliography.

  • Auditory time perception impairment in children with developmental dyscalculia
    by Elisa Castaldi on April 25, 2024

    Developmental dyscalculia (DD) is a specific learning disability which prevents children from acquiring adequate numerical and arithmetical competences. We investigated whether difficulties in children with DD spread beyond the numerical domain and impact also their ability to perceive time. A group of 37 children/adolescent with and without DD were tested with an auditory categorization task measuring time perception thresholds in the sub-second (0.25-1 s) and supra-second (0.75-3 s) ranges....

  • Are numerical abilities determined at early age? A brain morphology study in children and adolescents with and without developmental dyscalculia
    by Simone Schwizer Ashkenazi on April 20, 2024

    The intraparietal sulcus (IPS) has been associated with numerical processing. A recent study reported that the IPS sulcal pattern was associated with arithmetic and symbolic number abilities in children and adults. In the present study, we evaluated the link between numerical abilities and the IPS sulcal pattern in children with Developmental Dyscalculia (DD) and typically developing children (TD), extending previous analyses considering other sulcal features and the postcentral sulcus (PoCS)....

  • Supporting neurodivergent nursing students in their practice placements
    by Rachael Major on April 15, 2024

    Neurodivergent conditions such as autism, attention deficit hyperactivity disorder (ADHD), dyslexia, dyspraxia, dyscalculia and Tourette's syndrome are common, and it is highly likely that practice assessors and supervisors will be asked to support neurodivergent nursing students in their practice learning environments. This article details the strengths that neurodivergent students can bring to nursing, as well as some of the challenges they may experience in practice settings. It outlines how...

  • The development of number line estimation in children at risk of mathematics learning difficulties: A longitudinal study
    by Carola Ruiz on April 13, 2024

    Children with mathematics learning difficulties (MLD) show poorer performance on the number line task, but how performance on this task relates to other mathematical skills is unclear. This study examined the association between performance on the number line task and mathematical skills during the first 2 years of school for children at risk of MLD. Children (N = 100; M(age) = 83.63 months) were assessed on four occasions on the number line task and other mathematical skills (math fluency,...
