Severe stressors and traumatic events dramatically impact on us physically, emotionally and physiologically. Symptoms develop when these events overwhelm the nervous system’s ability to cope.
These symptoms are characterized by avoidance behaviours, heightened arousal and re-experiencing of the trauma in the form of flashbacks or intrusive memories.
Individuals can have extreme reactions to reminders of the traumatic event. Other symptoms include nightmares and sleep disturbances, depression and feelings of hopelessness, headaches, fatigue, memory problems, shock and anger.
