Abstract
Meta-analysis of 38 studies compared Wechsler IQ scores in affective disorder (A), lateralized right (RH), left (LH) and bilateral/diffuse (BI) brain damage. A, RH, and BI had lower PIQ than VIQ. In A and BI groups the PIQ/VIQ ratio was identical, whereas each differed significantly from the RH group which revealed a much lower PIQ/VIQ ratio. Similarity of neuropsychological profiles of A and RH patients is often interpreted as indicating predominant right-hemisphere involvement in affective disorder. The present findings suggest an alternative interpretation is possible: i.e., the presence of bilateral/diffuse CNS involvement in affective disorder. We do not believe that our findings strongly support one interpretation over the other. In future research, both possibilities should be considered.This publication has 52 references indexed in Scilit:
