Perinatal depression (PND) describes the onset of depression which can occur both before and after birth.
Ante natal depression can develop at any time during pregnancy and can be a precursor to post natal depression.
Postnatal depression is often first experienced within the first few weeks of giving birth, but can develop anytime within a year.
PND can feel extremely isolating and leave women with feelings of guilt and nagging questions about their abilities as a parent.
Whilst the exact cause of PND is not known, it is thought to be a result of a dramatic change in lifestyle and new challenges in everyday life. Some 15-20% of women experience some form of pregnancy related depression or anxiety.
