List some of the risk factors associated with the development of PTSD following a traumatic event.

PTSD, Post Traumatic Stress Disorder, is a condition that develops in some people who have experienced a shocking, scary, or dangerous event. It is usual to feel afraid during and after a traumatic situation. The 'fight-or-flight' response is a typical reaction meant to protect a person from harm. However, people with PTSD may feel stressed or frightened even months after they're no longer in danger, hence the name 'Post Traumatic'.

To identify the risk factors for PTSD, it's important to know that they fall into two categories: pre-trauma factors and post-trauma factors. Pre-trauma risk factors can include a family history of PTSD or depression, previous traumatic experiences, and childhood adversity, among others. Post-trauma risk factors include the severity, duration, and proximity of an individual's exposure to the traumatic event, and the individual's degree of their emotional reaction to the event.

1. Pre-trauma risk factors: \n- Family history of PTSD or depression: Having a family member who has had PTSD or depression might increase one's own risk. This could be due to both genetic and environmental influences.\n- Previous traumatic experiences: If one has lived through other traumatic instances, that could increase the risk of developing PTSD after the latest traumatic event.\n- Childhood adversity: People who experienced traumatic events as children, such as abuse or severe neglect, may be more likely to develop PTSD as adults. \n 2. Post-trauma risk factors: \n - Severity, duration, and proximity of exposure to the traumatic event: More severe and long-lasting traumatic events, or those that occurred close by, are more likely to result in PTSD. \n - Degree of one's own emotional reaction: If your emotional reaction during and after the traumatic event was extreme, you're more likely to develop PTSD.
