Cognitive Rehabilitation of Acquired Calculation Disturbances

Abstract EN

Acalculia is an acquired disorder in calculation abilities, usually associated with left posterior parietal damage.

Two types of acalculic disorders are usually distinguished: (1) primary acalculia or anarithmetia, where the patient presents a loss of numerical concepts (difficulties are observed both in oral and written calculations), and (2) secondary acalculia due to a different disturbance in cognition and affecting mathematical abilities.

Secondary acalculias are associated with aphasia, alexia, agraphia, executive function disorders, or visuospatial difficulties.

This paper is a proposal for clinical intervention to rehabilitation of acquired primary and secondary acalculias.
