Post-traumatic stress disorder (PTSD) is a psychiatric condition that affects individuals who have experienced traumatic events. The role of memory in the formation, as well as the maintenance of the trauma, is self-evident by the very nature of PTSD. The severity of trauma is affected by many factors, such as social, environmental, cultural, and personal. Women are more likely to develop PTSD due to the risk of sexual assault and abuse. The purpose of this paper is to examine the role of a long period of stressful environment in childhood and its influence on increased vulnerability to PTSD. Children who are exposed to abuse and trauma experience emotional dysregulation, making it harder for them to process and regulate emotions. This prolonged stressful environment becomes a major threat to emotional development. Children who grow up in such environments have an increased vulnerability to PTSD due to emotional dysregulation, hyper-vigilance and re-experiencing, lack of resilience and coping strategies, and trauma repetition. There can also be altered brain development in the areas of emotion regulation and stress response. “Additionally, there is the issue of hyper-vigilance and a lack of coping strategies due to the absence of support while growing up (CDC, n.d.).” Childhood trauma or abuse could be a major event, a regular experience, or a series of small issues persisting over a long period of time. The major literature on this topic overlooks the significance of smaller events occurring over long periods in a child’s life.
