These areas include the third frontal convolution pronunciation of numbersthe angular gyrus and the fissure interparietalis reading of numbersand the angular gyrus again for the writing of numbers. InLindquist proposed that lesions of different areas of the brain can cause different calculation defects, and that there are therefore several variations of acalculia.

Citations Publications citing this paper. The acaoculia was key in that it established calculation disorders as separate from language disorders, as the two were formerly associated.

Double dissociation between rote verbal and quantitative knowledge of arithmetic. Developmental calculation disturbances developmental dyscalculia are analyzed.


The term “acalculia” was coined by Henschen in ; it refers to the decrease in cognitive capacity for calculation that results from damage to the brain. Acalculia is associated with lesions of the parietal lobe especially the angular gyrus and the frontal lobe and can be an early sign of dementia.

Primary acalculia is a “pure” condition in which an individual can neither comprehend mathematical concepts diecalculia perform mathematical operations. Cognitive rehabilitation may be useful for the symptoms that interfere with activities of daily life, such as agraphia and acalculia.

Neuropsychology, Neuropsychiatry, and Behavioral Neurology. A proposed reinterpretation of Gerstmann’s syndrome. The enigma of Gerstmann’s syndrome revisited: Secondary acalculia is a loss of calculation abilities that stems from other cognitive difficulties, such as memory.

From Wikipedia, the free encyclopedia. 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.

The following tests are suggested:. The origins and development of numerical cognition: This therapy raised her caalculia ability to a high school level after she received treatment for a number of months. Studies of patients with lesions to the parietal lobe have demonstrated that lesions to the angular gyrus tend to lead to greater impairments in memorized mathematical facts, such as multiplication tableswith relatively unimpaired subtraction abilities.

Advancement requires the grasping of fundamental concepts before progressing to more difficult and involved concepts. Developmental arithmetic disorder Search for additional papers on this topic.

It has been questioned whether primary acalculia can exist independently of other cognitive impairments.

Henshcen’s research was consistent with Lewandowsky’s and Stadelmann’s finding. She was observed to have mixed up the arithmetical procedures and inadequately oriented the columns in mathematical problems. Localization acapculia Gerstmann syndrome.
