Abstract

The tetrad characterized by a disturb in the praxic knowledge o the fingers, right-left disorientation, dyscalculia and dysgrafia (Gerstmann syndrome) has been described as a developmental disorder, probably linked to a dysfunction refered to the gyrus angularis whether bilateral or even in the right hemisphere and independent of dyslexia. In this paper three cases of a Developmental Gerstmann syndrome are presented, where the three obliged symptoms were founded, and only in one case graphemic and orthographic levels are affected. Among the heterogeneity of the cases, the disorder in the mathematical domain can be considered as an anaritmetia, that is, a perturbation in the nuclear representation of the number. Theoretical consideration are proposed about the relation in the acquisition between the somestesic discrimination of fingers, an asymmetric representational space, and mathematical abilities.
