Acalculia following a dominant-hemisphere subcortical infarct
A. J. Corbett, E. A. McCusker and O. R. Davidson
A 60-year-old, right-handed woman experienced persistent impairment of
calculating ability following a subcortical infarct involving the head of
the left caudate nucleus, the anterior superior putamen, and the anterior
limb of the internal capsule extending superiorly into the periventricular
white matter. Acalculia resulted from defects of numerical syntax, the loss
of ability to manipulate mathematical concepts, and impaired working
memory.
