Dyscalculia, learning disability calculation

Dyscalculia is a learning disability in the calculation. It is classified as learning disabilities at school, such as dyslexia, dysorthographia ... This is not a simple problem in mathematics, but a severe and lasting disability. All the experts do not agree on its definition. For some it is a disorder of the function calculator (a difficulty with the addition). But for others, dyscalculia is a condition most importantly, linked to logical-mathematical reasoning (inability to understand numbers). Dyscalculia is still unknown and diagnosis is unfortunately later when the child is failing. And often dyscalculia is never diagnosed and persisted into adulthood ... Symptoms and signs of dyscalculia
Dyscalculia can occur in very different ways. Some children fail to grasp what is a number. They do not include the mathematical signs (+, -, x ...). So they are literally lost when it is manipulating numbers. Some do not even understand that a number is greater than another. Obviously, the multiplication tables is a real torture. These children may also have problems with a calculator. Sometimes it is only the calculation that is the problem, and the child may be good in geometry. But for others, the notions of space and time are simply absurd. They will be easily delayed, it will be difficult to distinguish their left and right, will not know the time to read or navigate on a map. Avoidance strategies and compensation of dyscalculia
As a result, many children end up being considered "invalid in math," reinforced this idea by their surroundings. They can also develop real strategies of compensation. They will use their fingers to count, much longer than other children. Indeed, other children use their fingers to count how. With dyscalculia, the fingers are literally counting, because the child does not understand ... To compensate for the disorder, the child may also develop a very strong imagination. Some dyscalculia are very good in the field of writing. The suffering caused by dyscalculia can lead to a phobia of mathematics. Causes of dyscalculia
The causes of dyscalculia are still unknown. It is unclear whether it is innate or acquired disorder. Dyscalculia might even be the manifestation of several different problems. At present, the research focuses on disruption of neurons related to the calculation in the region of the intra-parietal cortex.
Treatment of dyscalculia
There is currently no recognized treatment of dyscalculia. However, there are forms of therapy designed specifically for children with special difficulties in mathematics. To support dyscalculia, speech therapist diagnosed precisely the elements that cause problems for the child and seek the appropriate rehabilitation method. Current research to develop a therapy specific to dyscalculia seem on track. Software developed by the INSERM-CEA, the "Race Number" would work on children 4 to 8 years. It comes in the form of a game could be quickly adapted for children from 8 to 10 years.
