Maternal depression and warmth during childhood predict age 20 neural response to reward.

ABSTRACT: OBJECTIVE:Early parenting experiences likely shape children's brain development, with consequences potentially extending into adulthood. Parents' affective disorders and expressions of positive affect could exert an influence on affect-related circuitry. The current study evaluated how maternal depression and maternal warmth assessed in early childhood and early adolescence were related to boys' reward function during early adulthood. METHOD:Participants were 120 boys at socioeconomic risk for emotional problems. Mothers' history of depression during the child's lifetime was measured when boys were 42 months old and 10 and 11 years old. Maternal warmth was observed during mother-child interactions at 18 and 24 months and at 10 and 11 years. RESULTS:Maternal warmth during early childhood was associated with less activation in the medial prefrontal cortex (mPFC) when anticipating and experiencing reward loss. Maternal warmth during early adolescence was associated with less activation in the mPFC when winning rewards and greater activation in the caudate when experiencing loss. The association between maternal warmth during early childhood and early adolescence and reward function in the striatum and mPFC was stronger for boys exposed to maternal depression relative to boys who were not. CONCLUSIONS:The experience of warmth and affection from mothers may be a protective factor for reward function in boys exposed to maternal depression, possibly by engaging vulnerable neural reward systems through affiliation.

Project description:Disruption in the parent-child relationship is a commonly hypothesized risk factor through which maternal depression may increase risk for offspring psychopathology. However, maternal depression is commonly accompanied by other psychopathology, including antisocial behaviour. Few studies have examined the role of co-occurring psychopathology in depressed mothers. Using a longitudinal study of offspring of mothers with recurrent depression, we aimed to test whether maternal warmth/hostility mediated links between maternal depression severity and child outcomes, and how far direct and indirect pathways were robust to controls for co-occurring maternal antisocial behaviour.Mothers with a history of recurrent major depressive disorder and their adolescent offspring (9-17 years at baseline) were assessed three times between 2007 and 2010. Mothers completed questionnaires assessing their own depression severity and antisocial behaviour at Time 1 (T1). The parent-child relationship was assessed using parent-rated questionnaire and interviewer-rated 5-min speech sample at Time 2 (T2). Offspring symptoms of depression and disruptive behaviours were assessed using the Child and Adolescent Psychiatric Assessment at Time 3 (T3).Maternal hostility and warmth, respectively, mediated the association between maternal depression severity and risk for offspring psychopathology. However, the effects were attenuated when maternal antisocial behaviour was included in the analysis. In tests of the full theoretical model, maternal antisocial behaviour predicted both maternal hostility and low warmth, maternal hostility predicted offspring disruptive behaviour disorder symptoms, but not depression, and maternal warmth was not associated with either child outcome.Parenting interventions aimed at reducing hostility may be beneficial for preventing or reducing adolescent disruptive behaviours in offspring of depressed mothers, especially when depressed mothers report co-occurring antisocial behaviour.
