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.

- Activation and functional connectivity of cerebellum during reading and during arithmetic in children with combined reading and math disabilitiesby Sikoya M Ashburn on May 14, 2024
CONCLUSION: These results do not support theories that children's deficits in reading and math originate in the cerebellum.
- Diverging medical and legal perceptions of the need for legal guardianship in people with dementia: A qualitative studyby Kaisa Näkki on May 11, 2024
CONCLUSIONS: Physicians and legal experts diverged in their perceptions of cognitive and neuropsychiatric domains affecting mental capacity and the need for guardianship. The evaluation and influence of medical evidence among legal experts heavily rely on subjective opinions. Given the substantial potential impact on patients' equal access to their rights, developing standardized guidelines is essential.
- The typical and atypical developing mind: a common modelby Andreas Demetriou on May 9, 2024
We present a theory of atypical development based on a developmental theory of the typical mind integrating developmental, cognitive, and psychometric theory and research. The paper comprises three parts. First, it outlines the theory of typical development. The theory postulates central cognitive mechanisms, such as relational integration, executive and inferential processes, and domain-specific processes underlying different environmental relations, such as visuospatial or quantitative...
- Auditory time perception impairment in children with developmental dyscalculiaby 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....
