Review of the Research Literature on Dyscalculia: from Genetic Genealogy to Adaptive Teaching Tools

Posted on by

Dyscalculia is a common neurodevelopmental disorder characterized by difficulties in processing numerical information, understanding quantitative concepts, and performing simple mathematical calculations, and is seen in approximately 3 to 7 percent of children. This article reviews 61 studies between 2006 and 2025 to analyse the strategies and challenges of cognitive, neurological, and technological interventions. The results show that dyscalculia is a heterogeneous disorder and is associated with problems such as poor working memory, attention, cognitive inhibition, and math anxiety. Brain imaging findings such as fMRI show reduced activity in areas related to number perception, such as the interparietal sulcus and angular gyrus. Differences in the brain networks of children with dyscalculia can also help identify specific cognitive profiles. Four areas of intervention are proposed, including structured instruction, adaptive digital tools, early screening, and neurophysiological interventions (such as brain stimulation). Tools such as Calcularis and EDSense are effective in improving numerical skills and reducing anxiety. However, children with co-occurring disorders such as dyslexia or ADHD respond less well to interventions. Genetic studies also suggest genetic overlap between these disorders and deletions of genes such as 15q11.2. Finally, the need to design multi-layered, personalized interventions and use new technologies is emphasized to map out a more effective path to identifying and treating dyscalculia.

How Is Dyscalculia Diagnosed in Children

Posted on by

How is dyscalculia diagnosed, and why does it matter for a child’s future in school? Dyscalculia is a specific learning disorder that affects a person’s ability to understand numbers and core math concepts. While many children experience temporary math struggles, dyscalculia involves persistent math difficulties that interfere with learning, problem solving skills, and everyday math related tasks.

In the classroom, these challenges may appear as trouble learning basic math facts, completing math homework, or solving math word problems. At home, a child might struggle to count change, read an analog clock, or remember phone numbers. Because math skills are foundational for mathematics and other subjects, early identification is essential.

Parents and teachers often notice common signs but feel unsure about what they mean. Is it anxiety, lack of practice, ADHD, or a specific learning disability? Understanding how is dyscalculia diagnosed helps families determine the right assessment process and secure appropriate support.

This article explains the diagnosis step by step, clarifies the signs of dyscalculia in school age children, and outlines how professionals determine whether a child’s math difficulties reflect a learning difference or a formal learning disability.

Why Is Math Harder for Some Kids?

According to a study by Stanford Medicine, children with math learning disabilities do not process number symbols using two particular areas of the brain – but do not actually differ concerning the processing of dot-based quantities.

Could Something Medical Be Causing My Math Problems?

Posted on by

Sometimes math difficulties are related to other health conditions.

You should speak to a doctor if math problems are:

  • New or worsening in adulthood
  • Occurring after a head injury
  • Associated with memory loss
  • Linked to confusion or personality changes
  • Accompanied by vision problems
  • Occurring with stroke-like symptoms (sudden weakness, speech problems)

Sudden changes in math ability could signal a neurological issue, such as:

  • Brain injury
  • Stroke
  • Brain tumor
  • Seizure disorder
  • Neurodegenerative disease

These situations require urgent medical attention.

If your symptoms developed suddenly or feel severe, speak to a doctor right away.
