Hypercalculia

Hypercalculia is "a specific developmental condition in which the ability to perform mathematical calculations is significantly superior to general learning ability and to school attainment in maths."[1] A 2002 neuroimaging study of a child with hypercalculia suggested greater brain volume in the right temporal lobe. Serial SPECT scans revealed hyperperfusion over right parietal areas during performance of arithmetic tasks.[2]

Math and reading achievement profiles in autistic individuals

Children at any age may be stronger in language or in mathematics, but very rarely in both. Autistic children are no different. A study published in 2014 examined the reading and math achievement profiles and their changes over time within a sample of children between the ages 6–9 diagnosed with an autism spectrum disorder. What they found was that there are four distinct achievement profiles: higher-achieving (39%), hyperlexia (9%), hypercalculia (20%) and lower-achieving (32%).[3] A previous study conducted in 2009 estimated the rate of hypercalculia at 16.2% in ASD adolescents.[4][5]
