Mental health in the United Kingdom
Agnes Hann of the National Childbirth Trust said, "These findings are shocking, and mean that thousands of women experiencing potentially serious perinatal mental health problems are not getting the support they need. Perinatal mental illness can have a severe and long-term impact on mothers, babies and families. In extreme circumstances, it can result in tragedy – suicide is a leading cause of maternal death." From roughly 10% to 20% of women giving birth experience some type of mental illness such as anxiety and depression or more complex problems like PTSD and psychosis. With about 665,000 births a year in England 66,500–133,000 women a year develop illnesses. In 2016, 13,000 women were treated by perinatal teams while 800 became inpatients. This means the majority were untreated.
Intrusive thought
Unwanted thoughts by mothers about harming infants are common in postpartum depression. A 1999 study of 65 women with postpartum major depression by Katherine Wisner "et al." found the most frequent aggressive thought for women with postpartum depression was causing harm to their newborn infants. A study of 85 new parents found that 89% experienced intrusive images, for example, of the baby suffocating, having an accident, being harmed, or being kidnapped.
