Dyscalculia: the causes

Dyscalculia is therefore defined as a difficulty in learning and performing simple arithmetic calculations.

The causes of dyscalculia are complex, and often linked to many factors. One often finds a difficulty to structure the thought whose origin perhaps a deficiency, a retardation of development or a delay following difficulties of school order ...

The researchers hypothesized that dyscalculia is caused by an anomaly in the development of neural networks involved in calculus and number perception. Genetic factors could be at the origin of this dysfunction. These data have not yet been demonstrated.

There are not really different kinds of dyscalculia. However, dyscalculic disorder or logico-mathematical reasoning is not the same for each patient (child or adult), depending on the disorder (different logical structures, number, reasoning, language, operations, logic ...) and the age and stage of development of the patient.

In addition, there are frequent cases of dyscalculia in children of mothers with alcohol problems, and in children born prematurely.

When dyscalculia occurs in adulthood, it is often the result of brain injury due to an accident or trauma.
