Posttraumatic stress disorder (PTSD) is a debilitating psychiatric illness that results from exposure to real or threatened injury, death, and sexual/physical assault. These events then typically present in the form of negative changes in cognition and mood, hypervigilance, sleep disturbance, and irritability, among others.
PTSD can develop at any age. Children younger than six years old tend to reenact the traumatic event. Older children fantasize actions of revenge. Meanwhile in the elderly population, hyperarousal can happen. It is also interesting to know that medical events and procedures associated with life threats are associated with high rates of PTSD. Having a heart attack (also known as a Myocardial Infarction) is associated with up to 15% of PTSD episodes. Open abdominal aortic aneurysm repair is associated with approximately 20% of PTSD episodes.
As mentioned above, PTSD develops due to a traumatic event. This traumatic event creates a stress response that leads to behavioral changes that are found to be psychological and observable brain changes. Patients with PTSD have low levels of cortisol but high levels of corticotropin-releasing factor (CRF), which is a hormone in our body that initiates responses such as increased heart rate, blood pressure, increased arousal, and being startled.

The first step for prevention and control of PTSD is awareness of its signs and symptoms. This sets up the patient and their families to start early treatment and limit the burden of the illness. It is more important however, to seek professional help or packaged services where psychiatrists, psychologists, nurse practitioners, primary care providers, and social workers work together.
It is also advisable to develop a growth mindset by utilizing the Post-traumatic Growth Inventory (PTGI). This tool looks for positive responses in five areas:
Use this inventory to reflect on the traumatic event to better handle the disorder whenever it arises.
