Over the past few years, there has been an increase in media reports about postnatal depression and other maternal mental illnesses, and campaigns have led to greater understanding about the need for more specialist services. Although this is encouraging, little is said about fathers. But men can get postnatal depression, too.
Currently, only mothers can be diagnosed with postnatal depression. The psychiatrists' "Bible", the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), includes a diagnosis of "peripartum depression". Peripartum depression is a form of clinical depression that is present at any time during pregnancy, or within four weeks after giving birth, although experts working in perinatal mental health tend to be more flexible, extending that period to the first year after giving birth.
In many ways, postnatal depression varies little from traditional depression. It, too, includes a period of at least two weeks where the person experiences low mood or a lack of motivation, or both. Other symptoms include poor sleep, agitation, weight changes, guilt, feelings of worthlessness, and thoughts of death and dying. But the biggest difference is that a depression at this time involves a significant additional person: the child.
Evidence suggests that the long-term consequences of postnatal depression on the child can be damaging, including developmental problems, poor social interaction, partner-relationship problems and greater use of health services (including mental health services).
