Underlying Causes of a Panic Attack. In order to gain control of your panic symptoms, it can be helpful to understand the physiological reaction that underlies them. The first trigger in the chain of events happens in your brain.
Panic attacks typically last for less than 20 minutes. They start suddenly, sometimes for no obvious reason, sometimes in response to a stressful event, and sometimes as a result of exposure to a situation that has triggered previous panic attacks.udden onset of extreme anxiety, pounding heart, dizzyness, trouble breathing, apprehension, and a sense of doom or lack of ability to escape are signs of a panic attack. Peak anxiety usually occurs around 10 minutes after the start of the attack. However, in some rare cases a panic attack can go on for hours.
