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.
失算症是一种后天获得的计算能力障碍，通常与左后顶叶损伤有关。通常区分两种失算症：（1）原发性失算症或失数症，患者表现出数值概念丧失（口头和书面计算均存在困难）；（2）继发失算症，继发于认知障碍，影响数学能力。继发失算症与失语症、失读症、失写症、执行功能障碍或视空间困难有关。本文提出了一种针对后天原发性和继发性失算症康复的临床干预建议。
