Up to 5% of the Australian population will experience a panic attack at some point in their lives, however this does not mean that they have, or will have panic disorder.
Panic attacks can occur in the context of any mental disorder and some medical conditions, with the majority never meeting the criteria for panic disorder.
What is a Panic Attack?
A panic attack is a sudden rush of intense fear or discomfort that reaches a peak within minutes, and is accompanied by four or more of the following symptoms:
- A pounding heart, or increased heart rate
- Trembling or shaking
- Sensations of shortness of breath
- Feelings of choking
- Chest pain or discomfort
- Nausea or abdominal distress
- Feeling dizzy or light-headed
- Chills or heat sensations
- Numbness or tingling sensations
- Feelings of unreality, or being detached from yourself
- Fear of losing control or “going crazy”
- Fear of dying
The frequency of panic attacks can vary widely.
Some individuals have moderately frequent attacks (eg once a week for months at a time). Others experience short bursts of more frequent attacks (eg daily over many weeks) separated by months without an attack, or less frequent attacks (eg once a month) over many years. Individuals can also have both full-symptom (four or more), and limited-symptom (less than four) attacks, in which the number and type frequently differ from one panic attack to the next.
Types of Panic Attacks
There are two characteristic types of panic attacks: unexpected and expected.
Unexpected attacks are those for which there is no obvious trigger at the time of occurrence, for example, when relaxing or waking from sleep.
Expected panic attacks are attacks for which there is an obvious trigger, such as situations in which panic attacks have occurred.
How is it Diagnosed?
For a diagnosis of panic disorder, more than one unexpected full-symptom panic attack is required, followed by one month or more of persistent worry about having more panic attacks, and/or the individual changes his or her behaviour because of these attacks.
These worries about recurring panic attacks usually pertain to physical concerns (eg that you may have a life threatening illness), social concerns (eg embarrassment or fear that others will negatively judge you because of the visible symptoms), or mental functioning (eg losing control and “going crazy”).
Changes in behaviour refer to attempts to avoid or minimise panic attacks and their consequences, for example, restricting usual daily activities such as exercise due to fear of an increasing heart rate, avoiding certain situations and places such as using public transport or shopping, or re-organising daily life to ensure that there is help should you have a panic attack.
Although stressful situations can commonly trigger sudden overwhelming fear, recurring and unexpected panic attacks could be a sign of panic disorder.
What causes Panic Disorder?
While there is no one single cause, a number of factors are thought to contribute to developing the condition. These include:
- Genetic and Biological – Individuals with panic disorder tend to have a family history of anxiety and depressive disorders. Some medical conditions such as hyperthyroidism, asthma, and irritable bowel syndrome have been linked to panic disorder. Some studies also suggest a neurobiological cause, specifically, that the fear circuitry in the brain of individuals with panic disorder may be oversensitive and therefore can be triggered by events that are actually non-threatening.
- Environmental – Extremely stressful life experiences such as childhood maltreatment is more common in panic disorder than certain other anxiety disorders. Many people report interpersonal stressors, and stressors related to physical wellbeing in the lead up to their first panic attack. These include negative experiences with drugs (illicit and prescription), a death in the family, physical illness/injury, and social conflicts.
- Cognitive and temperament – It is thought that individuals with panic disorder have a higher sensitivity to internal bodily sensations (eg heart rate, breathing) and thus misinterpret any slight changes to be life threatening. This sensitivity, in addition to the negative thoughts that follow, are thought to be triggers to their symptoms. Those who are highly anxious, tense, moody, and self-conscious may also be at risk of developing this disorder.
How can a Psychologist help?
Psychologists are trained in evidence-based interventions, which are effective in resolving the condition.
Psychological-based treatments for panic disorder often involve psycho-education on the thought-anxiety connection, and the fight-flight arousal accompanying anxiety, as well as exposure therapy.
In exposure therapy, a safe environment is created in which to ‘expose’ you to the things you fear and avoid. Individuals with panic disorder who are sensitive to physical sensations can often misinterpret the sensations as indicative of a physical illness, thus may start to avoid situations, activities or places they believe put them at risk of experiencing feared sensations. As such, treatment might involve simulations of symptoms of high arousal to learn that your fears do not come true, helping you to learn that your physical sensations no longer make you anxious.
In some cases, panic disorder is due to anxieties piling up, but never being effectively processed. Therefore, in addition to exposure, treatment might include helping individuals identify, challenge and establish more adaptive thinking patterns, and learning relaxation strategies.
If you have experienced panic-like symptoms and feel that it has affected your work, school, personal life, or relationships, you may benefit from seeking support from your GP and/or a mental health professional. A psychiatrist or GP can also offer advice regarding whether medication might be beneficial, and determine whether your symptoms may be accounted for by a medical condition.
