In parallel, childhood maltreatment increases the risk of adult psychoses through unknown mechanisms.

The aim of the current study was to explore the cognitive factorial structure in subsamples from highly familial and densely affected kindreds of schizophrenia and bipolar disorder - i.e. affected(More)
