There has been comparatively less research on dyscalculia compared to some other learning disorders. Thus it can sometimes be difficult to diagnose. It not yet possible to diagnose dyscalculia based on brain function. Therefore diagnosis is more dependent on analysis of the effects of the disorder. It is considered good practice to take notes of your child symptoms and ask their teachers for their help and input, as this could be of great assistance to the diagnostic process.
The doctor will first run tests, a medical exam, and a clinical interview in order to understand more about the symptoms and to rule out other possible causes of the struggle with math, for instance anxiety disorders or other learning disabilities (or you child could just be bad at math!).
Once other possibilities have been ruled out and it is clear that your child is severely compromised in math and it causes an everyday struggle, and that he or she is suffering from some sort of learning disability, your doctor will conduct more tests.
Diagnostic tests will look at mathematical ability, IQ, reading and writing ability and so on. There are other methods that are sometimes used to diagnose dyscalculia, for instance your child’s doctor may ask them to count dots, to count backwards, and to copy and draw shapes form memory.
The results of these tests will be examined and understood on a person-to-person basis, as there is currently not a generalized set of indicators for dyscalculia. Once a diagnosis is made, it will be much easier to suggest treatment and therapy for the disorder.
