Panic disorder is an anxiety disorder primarily characterized by the experience of reoccurring, unexpected panic attacks. These attacks are sudden periods of intense fear accompanied by a range of physical and cognitive symptoms, such as palpitations, sweating, shaking, shortness of breath, numbness, and a profound sense of impending doom. The severity of these symptoms reaches its peak within minutes, making the experience both acute and highly distressing.
A significant aspect of panic disorder is not just the attacks themselves, but the ongoing worry about having further attacks and the subsequent avoidance behaviors that often develop.
Diagnostic Criteria and Characteristics
The diagnostic criteria for panic disorder, as outlined in the DSM-IV-TR, require unexpected, recurrent panic attacks. Crucially, following at least one of these attacks, there must be a period of at least a month during which the individual experiences a significant and related behavioral change, a persistent concern about having more attacks, or a worry about the attacks' potential consequences. This highlights that panic disorder extends beyond the individual episodes to encompass the psychological and behavioral impact they have on a person's life.
There are two main types of panic disorder: one with agoraphobia and one without. Agoraphobia involves a fear of situations where escape might be difficult or help unavailable, often leading to avoidance of public places or travel. It's important to note that a diagnosis of panic disorder is excluded if the attacks are due to a drug or a medical condition, or if they are better explained by other mental disorders. The ICD-10 diagnostic criteria further emphasize the essential feature as recurrent attacks of severe anxiety that are unpredictable and not restricted to any particular situation.
The Cycle of Worry and Avoidance
A central component of panic disorder is the persistent worry about experiencing future panic attacks. This apprehension can be debilitating, leading individuals to constantly monitor their bodily sensations and anticipate the next episode. This ongoing concern often fuels a cycle of avoidance, where people begin to steer clear of places or situations where they have previously experienced attacks, or where they fear an attack might occur. This avoidance can significantly restrict a person's life, impacting their social activities, work, and overall independence.
The dominant symptoms during these attacks, such as sudden onset of palpitations, chest pain, shortness of breath, dizziness, and feelings of unreality, contribute to the secondary fear of dying, losing control, or going mad. These fears, coupled with the unpredictability of the attacks, reinforce the avoidance behaviors. For instance, someone who experienced a panic attack in a crowded store might start avoiding all crowded places. This can escalate, leading to significant limitations in daily life and a reduced quality of life, as the individual's world shrinks to accommodate their fear of panic.
