Altered resting-state functional connectivity in the prefrontal cortex was related to the development of dyscalculia in patients with Turner syndrome.

We concluded that both groups of Turner syndrome patients shared visual deficits, and Turner syndrome patients with dyscalculia had a deficit in frontal cortex-based higher cognitive processing. It is not their visuospatial deficits, but rather their deficits in higher cognitive processing that are responsible for the development of dyscalculia in Turner syndrome patients.
