Treatment, therefore, is dedicated to the underlying neurological abnormality. The report was key in that it established calculation disorders as separate from language disorders, as the acaluclia were formerly associated. Warrington The Quarterly journal of experimental psychology…. However, damage to various but not necessarily identified areas of the brain can cause computational difficulties, as various cognitive functions are necessary to execute mathematical calculations.

Damage to the left angular gyrus is known to cause computational difficulties like those associated with primary acalculia and anarithmetia. A practical method for grading the cognitive dsicalculia of patients for the clinician.

There is a natural variation in the speed with which young schoolchildren grasp mathematical concepts, and those that have extreme difficulty retaining the foundations of mathematical concepts such as global quantification or numerosity perception are considered to have developmental dyscalculia.


There are several ways in which rehabilitation of acalculia is carried out. The case study reports that the patient also demonstrated “severe finger agnosia, and in fact the finger dsicalculia appeared to be directly related to her inability to perform calculations. Syndrome of finger agnosia, disorientation for right and left, agraphia, acalculia.

The rehabilitation techniques implemented included the following:. As calculation involves the integration of several cognitive skills, it is understood that an individual with acalculia or calculation difficulties is deficient in any of the following four realms: This article includes a list of referencesbut its duscalculia remain unclear because it has insufficient inline citations.

Acalculia and Dyscalculia

Acalculia is sometimes observed as a “pure” deficit, but is commonly observed as one of a constellation of symptoms, including agraphiafinger agnosia and right-left confusionafter damage to the left angular gyrus, known as Gerstmann’s syndrome.
