Panic Disorder
A panic attack is an abrupt surge of intense fear or intense discomfort that reaches a peak within minutes. Panic Disorder is not diagnosed from a single attack: it involves recurrent unexpected panic attacks and, for at least one month after at least one attack, persistent concern or worry and/or a maladaptive change in behaviour.
Symptoms may look like a medical emergency. Especially the first time or when the presentation is unusual, medical evaluation is needed. After other causes have been ruled out, evidence-based treatments can reduce both the attacks and the fear of the next one.
What Is Panic Disorder?
Unexpected panic attacks occur without an obvious immediate trigger, including at rest or during sleep. Frequency varies: attacks may occur often for a period or less frequently. The problem often continues between attacks as the person monitors bodily sensations, fears a heart attack, fainting, or loss of control, and avoids exercise, driving, or unfamiliar places. Expected panic attacks may also occur, but recurrent unexpected panic attacks are required for the diagnosis.
Key Features and Signs
A full-symptom panic attack includes at least four symptoms, such as:
- Tachycardia or rapid pulse, sweating and shaking.
- Shortness of breath, feeling of suffocation or chest pain and discomfort.
- Nausea or abdominal discomfort, dizziness, unsteadiness or feeling faint.
- Chills or feeling hot and numbness or tingling.
- Derealization or depersonalization: a sense of unreality or detachment from oneself or one’s surroundings.
- Fear of losing control, going "crazy" or dying.
- After an attack, persistent concern about another attack or avoidance of activities believed likely to trigger one.
How It Is Diagnosed
The clinician assesses the form and sequence of the panic attacks, what occurs between them, substance and medication use, and possible medical causes.
- There are recurrent unexpected panic attacks, each peaking within minutes and involving at least 4 of 13 physical or cognitive symptoms.
- At least one attack is followed for 1 month or more by persistent worry about new attacks or their consequences and/or maladaptive behaviour change.
- The presentation is not attributable to a substance, drug, or medical condition, such as certain cardiac, respiratory, or endocrine conditions.
- The panic attacks do not occur exclusively in the context of Social Anxiety Disorder, Specific Phobia, Obsessive-Compulsive Disorder, Posttraumatic Stress Disorder, Separation Anxiety Disorder, or another mental disorder.
How It Can Affect Daily Life
Fear of another panic attack may become more limiting than the attack itself. The person may avoid exercise because it raises the heart rate, travel without a companion, or places where help seems unavailable. Repeated medical tests or reassurance may be sought. When avoidance extends across multiple situations, assessment for Agoraphobia is also needed.
Causes and Risk Factors
The disorder is multifactorial. Familial vulnerability, sensitivity to bodily sensations, a tendency to interpret them catastrophically, stress, and avoidance learning may interact. Caffeine, stimulants, or withdrawal can trigger panic attacks in some people; in such cases, a substance/medication-induced condition must be considered.
Similar or Co-occurring Conditions
A panic attack is a symptom that can occur in many situations:
- In agoraphobia fear is of situations where escape or help seems difficult; it may co-occur.
- In social anxiety, specific phobia or PTSD the attacks are usually associated with a recognizable stimulus.
- Substances, drugs, hyperthyroidism, arrhythmias, asthma, and other medical causes need appropriate exclusion.
- Nocturnal panic attacks need to be distinguished from nightmares, sleep terrors, sleep apnoea and other sleep-related events.
Treatment and Support
Therapy targets both the attacks and the cycle of fear and avoidance.
- Cognitive-behavioural therapy for panic helps to understand bodily sensations and change catastrophic interpretations.
- Gradual exposure to safe physical sensations and avoided situations is organised with a suitable therapist.
- Medication may be an option after discussion with a physician. Selection, duration and discontinuation need monitoring.
- Cutting down on excessive caffeine, getting regular sleep, and limiting substance use can support the treatment plan, without replacing treatment.
When to Seek Help
Seek assessment when panic attacks recur, fear of another attack persists, or important activities are being avoided. New or severe chest pain, fainting, marked shortness of breath, a neurologic symptom, an attack following substance use, or symptoms that differ from the person's usual panic attacks require immediate medical assessment.
Frequently Asked Questions
Does one panic attack mean I have Panic Disorder?
No. It takes repeated unexpected attacks and at least a month of persistent worry or maladaptive behaviour change after one of them.
Can a panic attack happen in sleep?
Yes. A nocturnal panic attack can wake a person from sleep. It must be distinguished from nightmares, sleep apnea, and other conditions, especially when snoring, pauses in breathing, or unusual episodes are present.
How can I tell whether it is panic or a heart problem?
It is not always possible to distinguish it yourself. New or different chest pain, fainting, prolonged shortness of breath, or significant cardiovascular risk factors require immediate medical evaluation.
