Cognitive characteristics of the parents of schizophrenic patients.
This article reviews the empirical literature on cognition and communication in the parents of schizophrenic patients to address the questions of whether these parents as a group show evidence of any distinguishing cognitive characteristics and, if so, what those characteristics might be. Included in the review are studies of thought and communication disorder, and psychometric studies of cognitive functioning. We included only those that used reliable measures and included control groups in their designs. Taken together, the findings provide substantial evidence that nonschizophrenic parents of schizophrenic patients as a group demonstrate subtle cognitive difficulties in the area of concept formation and maintenance. There are also indications of other cognitive anomalies that will require further study. We discuss the importance of clarifying the etiological relevance of these findings and of pursuing further research in this area.
