Angular Gyrus Syndrome

Abstract

Damage to the inferior parietal lobe of the dominant hemisphere can produce the angular gyrus syndrome, which consists of transcortical sensory aphasia, alexia with agraphia, and Gerstmann's syndrome. Gerstmann's syndrome is the tetrad of acalculia, finger agnosia, left–right confusion, and agraphia. Although there has been controversy over the relevance or existence of Gerstmann's syndrome, it has been found in pure form in cases involving the left angular gyrus or underlying subcortical white matter.
