"If we are overwhelmed by the threat and are unable to successfully defend ourselves, we can become stuck in survival mode...This highly aroused state is designed solely to enable short-term defensive actions; but left untreated over time, it begins to form the symptoms of trauma. These symptoms can invade every aspect of our lives.."
(Levine 1999)
Trauma
Some traumas are isolated one-off events that are unexpected and happen ‘out of the blue’. Other traumas are frightening in different ways: they are expected, anticipated, and dreaded. Some people’s jobs expose them to trauma: military or emergency service personnel often experience or witness distressing events.
Children can experience trauma too – and the effects can be more profound and long-lasting if the people who were supposed to care for them were responsible for perpetrating harm.
It is normal to be affected by traumatic experiences. Victims of trauma might feel shocked, scared, guilty, ashamed, angry, or vulnerable. With time most people recover from their experiences or find a way to live with them, without needing professional help. However, in a significant proportion of people the effects of trauma last for much longer and may develop into post-traumatic stress disorder (PTSD). Symptoms of PTSD are split into groups [2]:
Re-experiencing symptoms.Re-experiencing memories of the trauma mean that memories of the event(s) play over and over in your mind. These memories can come back as ‘flashbacks’ during the day or as nightmares at night. The memories can be re-experienced in any of your five senses – you might see images of what happened, but may also experience sounds, smells, tastes, or body sensations associated with the trauma. Emotions from the trauma can also be re-experienced and it might feel as though the events are happening again. Re-experiencing symptoms include:
| Arousal symptoms.It is common to be ‘on edge’ or ‘on guard’ following a trauma. You might find it very difficult to relax or find that your sleep is affected. Arousal symptoms include:

Avoidance symptoms.A normal human way of dealing with physical or emotional pain is to avoid it or to distract ourselves. You might try to avoid any people, places, or any other reminders of your trauma. You might try very hard to distract yourself to avoid thinking about what happened. Avoidance symptoms include:
| Negative thoughts and mood.Trauma has a powerful effect on how we think. You might blame yourself for what happened, even if it was not your fault. Or you might replay parts of the trauma and think “what if …?” or “if only …”. Many people with PTSD also experience depression. Negative thoughts and mood about the trauma might include:

We can separate the effects of PTSD into behaviours.
