Abstract

Cloninger’s biopsychological model for personality distinguishes between Temperament [Novelty Seeking, Harm Avoidance (HA), Reward Dependence (RD), Persistence (PS)], and Character [Self-Directedness (SD), Cooperativeness (CO), Self-Transcendence (ST)] traits. Cloninger has also described three sets of complex interactions among these traits, which can be summarized as a linked network of three cubes. Within each cube, the different combinations of the sub-dimensions formulate multidimensional profiles that describe personality more accurately compared with their individual constituents. The aim of the present study was to examine differences of these multidimensional profiles in cognitive functions and Prepulse Inhibition (PPI) in unaffected relatives of schizophrenia-spectrum patients and control individuals. We assessed 114 unaffected relatives of schizophrenia-spectrum patients and 122 controls for Temperament/Character traits, a wide range of cognitive functions, and PPI of the acoustic startle reflex. The relatives had higher Ηarm Avoidance and Self-Transcendence along with lower Reward Dependence, Persistence, Self-Directedness and Cooperativeness scores as well as lower PPI and poorer cognition compared with controls. We also found a) unequal distribution of relatives and controls in several “disadvantageous” profiles associated with the schizophrenia-spectrum, b) the Schizotypal/Disorganized, Apathetic and Fragile profiles had poorer emotional decision making and attention switching, respectively, compared with their “advantageous” counterparts and c) the Adventurous, Independent, Bossy and Resilient profiles had higher PPI compared with their counterparts. These findings further highlight the significance of personality determinants of cognitive processes and have potential implications in early intervention programs in the schizophrenia-spectrum.

Abstract

Liability to schizophrenia is inversely correlated with general cognitive ability at both the phenotypic and genetic level. Paradoxically, a modest but consistent positive genetic correlation has been reported between schizophrenia and educational attainment, despite the strong positive genetic correlation between cognitive ability and educational attainment. Here we leverage published GWAS in cognitive ability, education, and schizophrenia to parse biological mechanisms underlying these results. Association analysis based on subsets (ASSET), a pleiotropic meta-analytic technique, allowed jointly associated loci to be identified and characterized. Specifically, we identified subsets of variants associated in the expected (“Concordant”) direction across all three phenotypes (i.e., greater risk for schizophrenia, lower cognitive ability, and lower educational attainment); these were contrasted with variants demonstrating the counterintuitive (“Discordant”) relationship between education and schizophrenia (i.e., greater risk for schizophrenia and higher educational attainment). ASSET analysis revealed 235 independent loci associated with cognitive ability, education and/or schizophrenia at p−8. Pleiotropic analysis successfully identified more than 100 loci that were not significant in the input GWASs, and many of these have been validated by larger, more recent single-phenotype GWAS. Leveraging the joint genetic correlations of cognitive ability, education, and schizophrenia, we were able to dissociate two distinct biological mechanisms: early neurodevelopmental pathways that characterize concordant allelic variation, and adulthood synaptic pruning pathways that were linked to the paradoxical positive genetic association between education and schizophrenia. Further, genetic correlation analyses revealed that these mechanisms contribute not only to the etiopathogenesis of schizophrenia, but also to the broader biological dimensions that are implicated in both general health outcomes and psychiatric illness.
