What Ever Happened to Developmental Gerstmann's Syndrome? Links to Other Pediatric, Genetic, and Neurodevelopmental Syndromes

Abstract

Developmental Gerstmann's syndrome is a neurodevelopmental disorder infrequently described in the literature. The limited literature might result from controversy surrounding developmental Gerstmann's syndrome as a "true syndrome." Developmental Gerstmann's syndrome requires a tetrad of symptoms: left-right confusion, finger agnosia, dyscalculia, and dysgraphia, with constructional dyspraxia often included as a fifth symptom. The etiology of developmental Gerstmann's syndrome is unknown, but several hypotheses have been proposed, and none have been conclusively confirmed. Based on the paucity of recent research on developmental Gerstmann's syndrome, individuals who meet the criteria for the disorder could be given other diagnoses. A clustering of neuropsychologic features across other seemingly related disorders suggests that the conceptualization of the tetrad of symptoms traditionally associated with developmental Gerstmann's syndrome more appropriately reflects soft signs that are commonly associated with a number of other neurodevelopmental disorders. Thus, although developmental Gerstmann's syndrome is of historical interest to neurodevelopmental specialists, there appears to be no basis for considering this disorder as a unique syndrome.
