Affecting approximately 5.7% of Australians, anxiety can vary from a slight sensation of unease to a terrifying panic attack. Anxiety is a dysfunctional reaction to a stressor or perceived threat. It reflects a combination of biochemical changes in the body, the patient’s personal history and memory, and the social situation. Anxiety disorders affect emotions, behaviour and physical well-being along with a significant increase to being at risk of comorbid conditions. Early intervention for anxiety disorders is imperative to reduce the risk of adverse outcomes such as alcohol and or drug addiction, depression or suicide. A large portion of human anxiety is produced by negative expectation or anticipation of future events.
