The children of mothers who experience perinatal depression are more likely to report psychotic experiences at the age of 18, a UK prospective cohort study has found. A joint analysis found an association between maternal antenatal depression symptoms and both offspring psychotic experiences and depression at age 18. Most of those with psychotic symptoms will not go on to develop psychosis or schizophrenia. However, they are still at increased risk of low educational and occupational achievement, social impairment, harmful drinking and substance misuse.
