Dyscalculia: News from the web:
Great article with indepth information about dyscalculia
Do read the whole article but here is the punch line:
Mathematical performance deficits, Developmental Dyscalculia, may arise because of a wide range of factors, from poor teaching, to low socio-economic status, to behavioral attention problems. However, a subset of children with math difficulties, possibly with the most-severe impairments, appears to suffer from a developmental learning disorder that undermines the ability to process basic numerical magnitude information, and that impairment in turn undermines the acquisition of school-level arithmetic skills. This disorder, “primary developmental dyscalculia,” should not be confused with “secondary developmental dyscalculia,” which refers to mathematical deficits stemming from external factors such as those described above. Instead, primary DD is associated with impaired development of brain mechanisms for processing numerical magnitude information and is thus driven by endogenous neurodevelopmental factors.
