As this paper will examine, the evidence is not irrefutably tied solely to the presence of maternal mental illness, and there are many competing factors that have to be taken into account when determining the cause of many of these children’s health and development differences. However, by the sheer volume and variety of the research taking place around the globe, it stands to reason that this should be an issue of paramount importance for the public health sector, and an area in which significant change should be possible.However, within the United Kingdom’s National Health System (NHS) the provisions and support offered to women remain hard to access, maintain, and most vitally, inconsistent across a range of factors including socioeconomic status and geographical location. Many women across the United Kingdom lack access to the appropriate screening, treatment and support needed to ensure they and their children are not neglected. This neglect not only places these children at increased risk of numerous developmental and health issues, but enhances an avoidable financial strain on the health system, as this assignment will investigate.This paper will focus on the children of mother’s with CMMHDs as specified by the Maternal Health Alliance, which include anxiety, depression (antenatal and postnatal), psychosis and post-traumatic stress disorder (PTSD). Although this research is respectful of the nuances of these various disorders, it is beyond the scope of this paper to comprehensively assess the individual systems in place for each respective disorder. Instead, this assignment will seek to more broadly assess the general provisions available for any mother in need of maternal mental health assistance in the United Kingdom, and the universal improvements that need to be made.
