Dyscalculia

Dyscalculia is a learning disorder, resulting in difficulty learning or comprehending arithmetic, such as difficulty in understanding numbers, numeracy, learning how to manipulate numbers, performing mathematical calculations, and learning facts in mathematics. In the United Kingdom it is classified as a specific learning difficulty. It is sometimes colloquially referred to as "math dyslexia." Dyscalculia is associated with dysfunction in the region around the intraparietal sulcus, and potentially also the frontal lobe. Dyscalculia does not reflect a general deficit in cognitive abilities or difficulties with time, measurement, and spatial reasoning. Estimates of the prevalence of dyscalculia range between three and six percent of the population. In 2015, it was established that 11% of children with dyscalculia also have attention deficit hyperactivity disorder (ADHD). Dyscalculia has also been associated with Turner syndrome, Down syndrome, and people who have spina bifida.
