Note: Symptoms of a panic attack – including chest pain, shortness of breath, and heart palpitations – should be evaluated medically to rule out cardiac and other medical causes before being attributed solely to anxiety. If you are unsure whether a symptom is a panic attack or a medical emergency, seek medical evaluation.

Panic disorder is a diagnosable anxiety disorder characterized by recurrent, unexpected panic attacks – sudden surges of intense fear accompanied by physical symptoms – followed by persistent concern about future attacks or significant behavioral changes. Many people who experience a panic attack for the first time believe they are having a heart attack or experiencing a medical emergency. Understanding what is physiologically happening during a panic attack can itself be a significant part of treatment.
Panic disorder affects approximately 2–3% of the population in any given year and is highly treatable. This article explains what panic attacks and panic disorder are, why they occur, and what evidence-based treatment involves.
What Is a Panic Attack?
A panic attack is a discrete episode of intense fear or discomfort that reaches a peak within minutes and includes at least four of the following DSM-5 symptoms:
- Palpitations, pounding heart, or accelerated heart rate
- Sweating
- Trembling or shaking
- Sensations of shortness of breath or smothering
- Feelings of choking
- Chest pain or discomfort
- Nausea or abdominal distress
- Feeling dizzy, unsteady, light-headed, or faint
- Chills or hot flashes
- Numbness or tingling sensations
- Derealization (feelings of unreality) or depersonalization (feeling detached from oneself)
- Fear of losing control or “going crazy”
- Fear of dying
Panic attacks can occur across many different conditions – including PTSD, specific phobias, social anxiety disorder, and major depressive disorder. The presence of panic attacks alone does not constitute panic disorder.
What Is Panic Disorder?
The DSM-5 defines panic disorder as recurrent unexpected panic attacks followed by at least one month of either:
- Persistent concern or worry about future panic attacks or their consequences (fear of losing control, having a heart attack, “going crazy”), or
- A significant maladaptive change in behavior related to the attacks – such as avoiding exercise, driving, being alone, or other situations associated with past attacks
The key differentiating feature of panic disorder is that the panic attacks are unexpected – they arise “out of the blue” without an identifiable trigger, at least initially. This unpredictability is central to why panic disorder produces such debilitating anticipatory anxiety.
Panic Disorder vs. Other Anxiety Disorders
| Condition | Core Feature | Type of Panic Attacks |
| Panic Disorder | Recurrent unexpected panic attacks + anticipatory anxiety about attacks | Unexpected, “out of the blue” |
| GAD | Persistent worry across multiple domains | Possible but not defining |
| Social Anxiety Disorder | Fear of scrutiny or humiliation in social situations | Situationally triggered by social exposure |
| Specific Phobia | Fear of a specific object or situation | Triggered by the specific feared stimulus |
| PTSD | Trauma-related symptoms including hyperarousal | Often triggered by trauma reminders |
What Causes Panic Disorder?
Panic disorder develops through the interaction of biological, psychological, and experiential factors:
- Genetic predisposition: There is a heritable component to panic disorder; having a first-degree relative with panic disorder increases risk
- Hyperactive fear response: Overactivation of the amygdala and related circuits produces a threat response that can be triggered by internal bodily sensations rather than just external threats
- Respiratory sensitivity: Some individuals with panic disorder are particularly sensitive to carbon dioxide and changes in respiratory patterns, which may contribute to panic onset
- Interoceptive conditioning: After an initial panic attack, normal bodily sensations (increased heart rate from exercise, caffeine, excitement) become conditioned to trigger anxiety – the body itself becomes a feared stimulus
- Catastrophic misinterpretation: Panic attacks are maintained by the tendency to catastrophically interpret benign physical sensations as evidence of impending disaster
- Stress and life events: Panic disorder often follows a period of elevated stress, a major life transition, or a first unexpected panic attack
Panic Disorder and Agoraphobia
Agoraphobia – a condition characterized by fear and avoidance of situations in which escape would be difficult or help unavailable during a panic attack – frequently develops alongside panic disorder. Common avoided situations include public transportation, open spaces, enclosed spaces, crowds, and being away from home alone.
An important clarification: agoraphobia is not simply fear of open spaces. It is specifically fear of situations where a panic attack would be difficult to manage or escape. The DSM-5 now treats agoraphobia as a distinct diagnosis, separable from panic disorder – though the two frequently co-occur.
When agoraphobia accompanies panic disorder, avoidance often escalates over time – narrowing the person’s world significantly if left untreated. Treatment requires directly addressing the avoidance behavior alongside the panic attacks themselves.
Treatment for Panic Disorder
Cognitive Behavioral Therapy – Gold Standard
CBT is the most evidence-based treatment for panic disorder and produces lasting results for the majority of people who engage with it. CBT for panic disorder typically includes:
- Psychoeducation about the physiology of panic – understanding that panic attacks, while intensely uncomfortable, are not physically dangerous
- Cognitive restructuring – challenging catastrophic interpretations of physical sensations
- Interoceptive exposure – deliberately inducing feared physical sensations (through exercise, hyperventilation, spinning) to break the association between sensation and danger
- In vivo exposure – gradually approaching avoided situations to disconfirm feared predictions
- Breathing retraining – diaphragmatic breathing and its role in regulating physiological arousal
Mindfulness-Based Approaches
Mindfulness-Based Stress Reduction (MBSR) builds the capacity to observe anxious sensations without reacting, reducing the catastrophic amplification that drives panic attacks.
Medication
SSRIs and SNRIs are considered first-line medications for panic disorder and are typically taken daily on an ongoing basis. Benzodiazepines may be used short-term for acute management but carry risks of tolerance and physical dependence with regular use. Medication decisions should be made in consultation with a prescribing clinician.
Neurofeedback
Neurofeedback is used as an adjunctive approach to help regulate the overactive fear response and high-arousal brain states associated with panic disorder, supporting the physiological dimensions of treatment.
Frequently Asked Questions
Can panic disorder be cured?
Many people with panic disorder achieve full remission of panic attacks and anticipatory anxiety with evidence-based treatment – particularly CBT. For others, the condition becomes highly manageable with ongoing treatment. Research suggests that treatment gains from CBT tend to be durable, often maintained for years after active treatment ends.
Is panic disorder the same as anxiety?
Panic disorder is a specific anxiety disorder, but it is distinct from generalized anxiety disorder and other anxiety conditions. The defining feature – recurrent unexpected panic attacks followed by persistent concern about future attacks – sets panic disorder apart from other presentations. Understanding the specific type of anxiety present is important for choosing the most effective treatment approach.
Can panic attacks happen during sleep?
Yes. Nocturnal panic attacks – waking suddenly from sleep in a state of intense fear and physical arousal – do occur and can be particularly frightening. They are more common than many people realize. The same treatment approaches used for daytime panic attacks are effective for nocturnal panic.
Should I go to the ER during a panic attack?
If you are experiencing chest pain, difficulty breathing, or other symptoms that could indicate a medical emergency – especially if you have not previously been evaluated for these symptoms – seeking medical evaluation is appropriate. Once cardiac and other medical causes have been ruled out, a mental health evaluation is the appropriate next step. Many people with panic disorder have visited emergency rooms multiple times before receiving a correct diagnosis.
