Panic Disorder is defined by the DSM 5 “as recurring, unexpected panic attacks characterized by an abrupt surge of intense fear or discomfort that reaches a peak within minutes.” There are subsequently fears regarding the attack such as preoccupation with additional attacks and worry about the possible meaning or consequences of the attacks. Often, but not always, panic can lead to “agoraphobic” avoidance of situations, activities or reliance on what is commonly referred to as safety-seeking behaviors.
Agoraphobia is defined as anxiety about places, situations or even activities where escape might be difficult or where help might not be available if a panic attack were to occur. Agoraphobia usually develops as a result of panic disorder. People with agoraphobia often avoid a broad range of situations such as large indoor or outdoor places or venues, being alone, doing something alone outside of the home, crowds, bridges, elevators and/or traveling by car, plane, train or airplane. Agoraphobic avoidance is self-reinforcing, often begets avoidance and consequently can spread across many areas of a person's life. Untreated this can lead to serious limitations and disability. Panic can occur alone but often progresses to agoraphobic avoidance as situations and activities become associated with the panic attacks ( associative learning ).
The estimated lifetime prevalence of panic in the general population is between 1.5 and 3.5 %. Women are twice as likely to experience panic than are men; although the clinical feature of the disorder are similar across the genders.
Panic Control Treatment (PCT)- a patchwork of CBT methods, adapted to the treatment of panic by American psychologist David Barlow in the 1980s. Through years new generations of researchers, working with Barlow at the Center for Anxiety and Related Disorders at Boston University, have developed trans-diagnostic approaches for anxiety. Nonetheless, the PCT is still considered a first line approach for panic disorder.
The pioneering model developed by Barlow, collaborator, Michelle Craske and UK researcher David Clark targeted key aspects of the cycle of panic for change, particularly fight-or-flight false alarm, the catastrophic misinterpretation of this misdirected biological survival reaction, along with maladaptive "safety behaviors".
