What is dyscalculia?

Dyscalculia is a disability resulting in difficulty learning or comprehending  arithmetic, such as difficulty in understanding numbers, learning how to manipulate numbers, performing mathematical calculations and learning facts in mathematics.

Dyscalculia is associated with dysfunction in the region around the intraparietal sulcus and potentially also the frontal lobe. Dyscalculia can occur in people from across the whole  IQ range, along with difficulties with time, measurement, and spatial reasoning. Estimates of the prevalence of dyscalculia range between three and 6% of the population. In 2015, it was established that 11% of children with dyscalculia also had ADHD. Dyscalculia has also been associated with people who have Turner syndrome and people who have spina bifida.
