Panic disorder | Azimuth Check

A panic attack can feel as though something terrible is happening to the body. The heart races, breathing becomes difficult, dizziness or trembling may develop, and the person may fear losing control, fainting or dying. The experience can be frightening, particularly when it occurs unexpectedly or without an obvious explanation.

A panic attack is an episode of intense fear or discomfort accompanied by physical and psychological symptoms. Experiencing one does not automatically mean that a person has panic disorder. The disorder involves recurrent, often unexpected panic attacks alongside persistent concern about further attacks or changes in behaviour intended to prevent them.

1. What happens during a panic attack?

Panic activates the body's threat-response system. This prepares us to deal with perceived danger by changing breathing, heart rate, muscle tension and attention. When the response is triggered intensely, the resulting sensations can themselves become frightening.

Symptoms may include a pounding heart, sweating, trembling, breathlessness, chest discomfort, nausea, dizziness, tingling, chills or hot flushes. Some people experience a sense of unreality or feel detached from their surroundings. Others become intensely afraid that they are losing control or experiencing a serious medical emergency.

Panic attacks commonly reach their peak within minutes, although after-effects can last longer. The physical sensations are real, but interpreting them as catastrophe may intensify the attack. New, severe or unexplained physical symptoms should not automatically be attributed to anxiety. Chest pain, severe breathing difficulties or other possible emergency symptoms require urgent assessment.

2. When does panic become panic disorder?

An isolated panic attack may occur during a stressful period, in response to a particular situation or without an identifiable trigger. Many people experience an attack without developing a longer-term disorder.

Panic disorder involves recurrent unexpected attacks and at least a month of persistent concern about further attacks or their consequences, or significant behavioural changes related to them. A person may become preoccupied with monitoring their body, interpreting ordinary sensations as warning signs or avoiding places where an attack might occur.

This anticipatory fear can become as disruptive as the attacks themselves. Someone may stop exercising because an increased heart rate feels dangerous, avoid travelling alone or repeatedly seek reassurance. Avoidance often brings short-term relief, yet can reinforce the belief that particular situations or sensations are unsafe and make it harder to regain confidence.

3. Why does panic develop?

Panic disorder does not have one single cause. Biological vulnerability, stressful experiences, physical health, sleep disruption and individual patterns of interpreting bodily sensations may contribute.

One important mechanism is the fear of fear itself. After a frightening attack, a person may become highly attentive to normal bodily changes. A slight increase in heart rate or moment of dizziness can be interpreted as the beginning of another episode. This interpretation increases anxiety, which can intensify the sensations and appear to confirm the original fear.

Repeated checking, reassurance-seeking and avoidance may maintain the cycle by preventing the person from learning that familiar sensations can often be tolerated without the feared outcome occurring. This is not to suggest that panic is imaginary; it explains how a genuine physiological response can become associated with persistent fear.

4. Assessment and treatment

Assessment considers the symptoms during attacks, their frequency, whether they occur unexpectedly, fear of recurrence and effects on everyday life. A GP may also consider physical conditions or substances that can cause similar symptoms. Depending on the presentation, medical assessment may be necessary before symptoms are attributed to panic.

CBT is an established treatment for panic disorder. It helps people understand the relationship between physical sensations, interpretations and fear. Treatment may include responding differently to catastrophic thoughts and, where appropriate, gradually approaching feared sensations or situations under professional guidance.

Medication may be considered when symptoms are persistent or significantly affect functioning. Antidepressants, including SSRIs, are among the options used. A prescriber can discuss benefits, side effects and discontinuation effects.

During an attack, finding a safe place, gently slowing the breath without forcing it and bringing attention to the immediate surroundings may help. These approaches are not guaranteed to stop an attack and should not become rigid rituals. Regular sleep, physical activity and reduced reliance on caffeine or other stimulants may also support management.

5. Recovery and rebuilding confidence

Recovery often involves rebuilding confidence in the body, returning to avoided activities and learning that uncertainty can be tolerated without constant monitoring. Progress is not always linear. An occasional attack does not necessarily indicate that treatment has failed.

What matters is whether the person becomes less frightened by the sensations, less dependent on avoidance and more able to continue with everyday life. Many people learn to recognise the panic response without automatically interpreting it as evidence of danger, while still seeking medical assessment for new or unusual symptoms.

When to seek urgent help

If symptoms are new, severe or could indicate a medical emergency, call 999 or seek emergency care. If recurrent panic is affecting daily life, contact a GP for assessment and treatment options.
