Polygenic scores for schizophrenia and general cognitive ability: associations with six cognitive domains, premorbid intelligence, and cognitive composite score in individuals with a psychotic disorder and in healthy controls.

Except for a nominally significant association to verbal learning for individuals with psychosis ( β = −0.11, p = 0.03), there were no significant associations between the PGS SCZ and the remaining cognitive phenotypes (numerical values for β s, 95% confidence intervals (CIs), and p values for both participants with psychosis and healthy controls are presented in Supplementary Table S1 ).
