Post-traumatic stress disorder can be developed when you see or learn about an event, including threatened or actual death, sexual violation, or severe injury. While doctors are not certain of the exact reason why people develop PTSD, but here some of the reasons that may contribute to this disorder –
1. Inherited mental health risks like a family history of depression and anxiety.
2. Stressful experiences including the severity and amount of trauma you have experienced in life.
3. Inherit characteristics of your personality, known as temperament.
4. The way the brain regulates hormones as well as chemicals in response to stress.
