Investigating if psychosis-like symptoms (PLIKS) are associated with family history of schizophrenia or paternal age in the ALSPAC birth cohort

Overall our findings provide little evidence that these established risk factors for schizophrenia show a similar relationship with PLIKS, suggesting that the presence of PLIKS is unlikely to be a strong marker of early expression of the pathology underlying schizophrenia. Whether future studies of PLIKS will increase our understanding of mechanisms underlying the development of schizophrenia, or prove useful in prediction of this disorder, remains to be seen.
