Anxiety & Stress

Anxiety is a multi system response to a supposed threat or danger. It shows a amalgamation of biochemical alteration in the body, the patient's personal history and memory, and the social state. As much as we know, anxiety and stress is an exclusively human experience. Other animals clearly know fear, but human anxiety includes an ability, to apply memory and mind to move backward and forward in time, that animals do not come out to have. The anxiety that take place in post-traumatic syndromes indicates that human reminiscence is a much more complex mental function than animal memory. Furthermore, a large part of human anxiety is produced by anticipation of future events. Without an intelligence of personal continuity over time, people would not have the "raw materials" of anxiety. Difference between anxiety and various others emotional conditions, like fear or even 'arousal', are not always clear. Also, there are close relations between emotion and cognition: man has the aptitude not only to know, but also to react emotionally to what he knows.
