Perinatal mental disorders are associated with increased risk of psychological and developmental disturbances in children. However, these disturbances are not inevitable. ⋯ We review research of interventions, which are mostly about maternal depression, and emphasise the need to both treat the parent's disorder and help with associated caregiving difficulties. We conclude with policy implications and underline the need for early identification of those parents at high risk and for more early interventions and prevention research, especially in socioeconomically disadvantaged populations and low-income countries.
