Common symptoms of dyscalculia are having difficulty with mental math, trouble analyzing time and reading an analog clock, struggle with motor sequencing that involves numbers, and often counting on fingers when adding numbers. It tends to become more apparent as children get older however, symptoms can appear as early as preschool. Dyscalculia often looks different at different ages. However, children with dyscalculia can subitize fewer objects and even when correct take longer to identify the number than their age-matched peers. Children as young as five can subitize six objects, especially looking at a die. The earliest appearance of dyscalculia is typically a deficit in subitizing, the ability to know, from a brief glance and without counting, how many objects there are in a small group. Mathematical disabilities can occur as the result of some types of brain injury, in which case the term acalculia is used instead of dyscalculia, which is of innate, genetic or developmental origin. Dyscalculia has also been associated with Turner syndrome and people who have spina bifida. In 2015 it was established that 11% of children with dyscalculia also have ADHD. Estimates of the prevalence of dyscalculia range between 3 and 6% of the population. Dyscalculia does not reflect a general deficit in cognitive abilities or difficulties with time, measurement, and spatial reasoning. ĭyscalculia is associated with dysfunction in the region around the intraparietal sulcus and potentially also the frontal lobe.
It is sometimes colloquially referred to as "math dyslexia", though this analogy is misleading as they are distinct syndromes.
