Post-traumatic stress disorder (PTSD) is a complex disorder that is the reaction to a traumatic event. Traumatic events that can result in PTSD often include war, rape, kidnapping, assault, natural disasters, car or planes crashes, terrorist attacks, sudden death of a loved one, sexual or physical abuse, extreme bullying, death threats, and childhood neglect. The symptoms of PTSD can arise suddenly, gradually, or come and go over time. PTSD does not just affect the person with the condition; it also affects the loved ones who are involved in his or her life. If you are living with someone with PTSD, it is important to recognize how PTSD can affect your home life, learn how to deal with symptoms of PTSD that may arise, and help your loved one in as many ways as you can.
