Evidence of Common Genetic Overlap Between Schizophrenia and Cognition

Our results support the presence of shared common genetic factors between schizophrenia and childhood cognitive ability. We observe a genetic relationship between schizophrenia and performance IQ but not verbal IQ or other cognitive variables, which may have implications for studies utilizing cognitive endophenotypes for psychosis.

Although not diagnosed with schizophrenia my non verbal IQ is significantly lower than my verbal IQ. Performance IQ tests non verbal capabilities.
