Problems related to chronic, untreated NDD during adulthood are viewed through the lens of pregnant and postpartum mothers to highlight unique struggles as their family unit expands after having children. The content is based on the author clinical experience with mothers under her psychiatric care between 2017-2024 at an outpatient practice, affiliated with Brown University. Comorbid psychiatric problems such as anxiety, mood disorders, trauma and substance use disorders are also reviewed. In addition to sharing clinical anecdotes, the author presents a consolidated review of scientific literature on the subject.
