Ricardo Tavares Pinheiro from the Universidade Católica de Pelotas in Brazil will identify factors that are associated with gestational depression, and determine whether they influence their response to treatment and ultimately the healthy development of the child. Gestational and postpartum anxiety and depression affect 15-25% of mothers and can alter the emotional, social and cognitive development of the child. They are likely caused by a complex combination of genetic, hormonal, psychological and social/environmental factors.
