Post-traumatic stress disorder (PTSD) is “the development of a set of reactions in people who have experienced a traumatic event that might have threatened their life or safety, or others around them. Examples of traumatic events can include war or torture, serious accidents, physical or sexual assault, or disasters. A person who has PTSD can experience feelings of helplessness, horror or intense fear.” (Australian Institute of Health and Welfare)

Post-traumatic stress disorder is when memories of a traumatic event are relived and affect a person physically and/or emotionally. Flashbacks can be triggered by sounds, smells and images.

People may experience flashbacks, nightmares, sweating, palpitations and panic, trouble sleeping, angry and emotional outbursts, feelings of hopelessness and not feeling safe. They may avoid things that remind them of the trauma they have experienced or be constantly on alert for threats. Some people experience no emotion, feel numb and may be unaware of things that are happening around them.

The steps people take to avoid trauma-related stimuli is part of the diagnosis and important for workers, who may not understand why the person does not want to do particular things.
