A panic attack is an abrupt burst of overwhelming fear and anxiety. Oftentimes, panic attacks occur unexpectedly, and may even happen when the individual is in a relaxed or sleeping state. Individuals suffering from panic disorder experience sudden recurring attacks of anxiety or fear. With good reason, most individuals affected by panic disorder dread the likelihood of experiencing attacks. This fear can cause individuals to avoid situations of daily life, particularly those where they feel that escape would be difficult (e.g., driving across a bridge, going to the movies, standing in a long line). Over six million Americans suffer from panic attacks each year and sadly a majority of these individuals do not realize that panic attacks are highly responsive to treatment.
