Dyscalculia: News from the web:

There is still research necessary to find out exactly where Dyscalculia finds it’s origin:

Two hypotheses attempt to explain the main cause of dyscalculia. The first hypothesis suggests that a problem with the core mechanisms of perceiving (non-symbolic) quantities is the cause of dyscalculia (core deficit hypothesis), while the alternative hypothesis suggests that dyscalculics have problems only with the processing of numerical symbols (access deficit hypothesis). In the present study, the symbolic and non-symbolic numerosity processing of typically developing children and children with dyscalculia were examined with functional magnetic resonance imaging (fMRI). Control (n=15, mean age: 11.26) and dyscalculia (n=12, mean age: 11.25) groups were determined using a wide-scale screening process.
