London, Nov 3: The most acute form of post-natal depression might be linked to genes, says researchers.
The study led by Cardiff University, Birmingham University and Trinity College, Dublin suggests that the severe version of the condition, known as postpartum psychosis, may have a genetic cause.
The condition affects around one in 500 new mothers, and includes mood disorders.
It is believed that the mood disorders were caused by women''s circumstances, personality and hormonal changes.
