Panic Disorder Symptoms: The Complete Guide to Attack-Level, Pattern-Level, and Comorbid Symptoms, Severity Grading, and When to Seek Treatment

GO TO THE ER NOW

If you are experiencing any of the following, call 911 (US) or 999 (UK) or 112 (EU) immediately. Do not wait:

Chest pain that is heavy, crushing, or radiating to your arm, jaw, or back
Severe shortness of breath at rest
Fainting or feeling like you will faint
Slurred speech, confusion, or difficulty speaking
Sudden severe headache or weakness on one side of your body
Blue lips or severe difficulty breathing
Loss of consciousness
First-ever episode of these symptoms (cannot assume it is panic without medical evaluation)

This guidance follows Mayo Clinic and American Heart Association protocols. See PAG row #17 (Panic Attack vs Heart Attack) for detailed cardiac distinction. A chest pain ER visit is the correct call, even if it turns out to be panic. Anxiety is a diagnosis of exclusion, meaning cardiac disease must be ruled out first per the American College of Emergency Physicians.

Direct Answer: Panic Disorder Symptoms

Panic disorder symptoms span two distinct tiers: acute attack symptoms and persistent disorder-pattern symptoms. The acute tier comprises the 13 DSM-5 panic attack criteria (pounding heart, chest pain, shortness of breath, dizziness, numbness, derealization, depersonalization, nausea, sweating, chills, trembling, fear of dying, fear of losing control), with at least 4 required, peaking within minutes and resolving within 20 to 30 minutes per attack. The disorder-pattern tier, what separates panic disorder from a single panic attack, includes recurrent unexpected attacks (2 or more), persistent anticipatory anxiety between attacks ("When will the next one hit?"), significant behavioral changes and avoidance (avoiding places, situations, or activities where panic previously occurred), safety behaviors (always carrying medication, never going alone, checking heart rate constantly), hypervigilance to body sensations, sleep disruption from worry about nocturnal panic, secondary depression and mood disturbance, reduced activity and lifestyle shrinkage, and functional impairment in work, relationships, or parenting. The disorder-level pattern requires at least one month of persistent worry or avoidance behavior per DSM-5. Panic disorder is chronic, waxing and waning in severity without treatment, and often complicated by agoraphobia (fear of escape-difficult situations) or comorbid depression (about 50 percent of people with panic disorder). Recognizing the distinction between a single frightening panic attack and the sustained disorder is essential for understanding why anticipatory anxiety, not the attacks themselves, becomes the greatest source of disability.

The Two-Tier Symptom Framework: Attack Symptoms vs Disorder-Pattern Symptoms

Understanding panic disorder requires distinguishing between what happens during an acute panic attack and what happens between attacks. This two-tier framework clarifies why one terrifying panic attack is not panic disorder, and why the anticipatory anxiety is often more disabling than the attacks themselves.

Tier 1: Acute Panic Attack Symptoms (During the Attack)

These are the 13 DSM-5 diagnostic criteria. Per the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, at least 4 of the following must be present, with symptoms peaking within 5 to 10 minutes:

Cardiovascular Symptoms

Pounding heart or accelerated heart rate (tachycardia) climbing to 100-150+ bpm
Chest pain or discomfort (pressure, tightness, sharp, pinpoint, or radiating sensations)
Feeling that the heart will burst, stop, or fail

Respiratory Symptoms

Shortness of breath or sensation of choking
Sensation of lump in the throat preventing swallowing

Neurological and Sensory Symptoms

Dizziness, lightheadedness, or fear of fainting
Numbness or tingling sensations (paresthesia), typically around the mouth, hands, feet, or one-sided on the face
Derealization: the world feels unreal, distant, flat, or viewed through glass
Depersonalization: feeling detached from your body, watching yourself from outside, or body feeling robotic

Gastrointestinal Symptoms

Nausea or abdominal distress (cramping, urgent need to use the bathroom)

Thermoregulatory Symptoms

Sweating (cold, clammy sweat, not warm anxiety sweat)
Chills or heat sensations (hot flushes followed by ice-cold shivers)

Motor Symptoms

Trembling or shaking (hands, legs, voice, or whole body)

Psychological Symptoms

Fear of losing control or going crazy
Fear of dying

For the complete phenomenology of attack symptoms, including detailed mechanistic explanations and common non-DSM-5 symptoms (blurred vision, sense of impending doom, urge to flee), see PAG #2 (Panic Attack Symptoms).

Tier 2: Disorder-Pattern Symptoms (Between and Beyond Attacks)

These symptoms are what define panic disorder as distinct from a single panic attack. They occur between attacks, persist for at least one month, and reflect the way the brain and behavior change in response to recurrent panic. These are often more disabling than the attacks themselves.

Recurrent Unexpected Panic Attacks

2 or more panic attacks, sudden and uncued (not triggered by an obvious external event)
Attacks may occur while sitting, sleeping (nocturnal panic), watching television, or in any situation
Pattern of attacks waxing and waning: frequent for a period, then less frequent, potentially triggered by stress or seasonal factors

Anticipatory Anxiety: The Worry Between Attacks

Persistent, intrusive worry about having another attack: "When will it hit? What if I'm at work? What if I'm driving on the highway?"
Catastrophic interpretation of bodily sensations: a slight heart rate increase, mild dizziness, or normal body sensation triggers a panic spiral
Fear of fear: the person becomes anxious about anxiety itself, hypervigilant to any sensation that preceded a previous attack
Sleep disruption: worry about nocturnal panic, difficulty falling asleep, early morning awakening with panic
Constant monitoring and body scanning: checking heart rate, breathing, dizziness, searching for signs that an attack is coming

Unlike a panic attack (which peaks and resolves within 30 minutes), anticipatory anxiety is chronic and persistent, often worsening in the morning or evening.

Behavioral Changes and Avoidance

Avoidance of places where panic previously occurred: grocery stores, shopping malls, highways, public transportation, crowded venues, enclosed spaces (elevators, airplanes)
Avoidance of situations thought to trigger attacks: avoiding physical exertion, caffeine, heat, certain foods, or specific social situations
Avoidance of activities: giving up driving, avoiding work situations, declining social invitations, avoiding travel
Lifestyle shrinkage: quitting a job, staying home instead of leaving the house, withdrawing from hobbies

Safety Behaviors: Maladaptive Coping Strategies

Always carrying medication, even if not used
Requiring a companion to leave the house or go to certain places
Sitting near exits or keeping escape routes open
Frequent checking of vital signs (heart rate, blood pressure) with pulse oximeter or smartwatch
Repetitive reassurance-seeking from partners, family, or doctors
Use of alcohol, sedatives, or prescription benzodiazepines to manage anticipatory anxiety
Holding tight to objects or people for perceived safety

Safety behaviors are counterproductive: they amplify anxiety long-term because they prevent the person from learning that the feared outcome (panic attack, heart attack, or collapse) does not actually occur.

Hypervigilance to Body Sensations (Interoceptive Sensitivity)

Excessive awareness and focus on internal body signals: breathing, heart rate, stomach sensations, dizziness
Misinterpretation of normal sensations as signs of danger: normal heart palpitation interpreted as arrhythmia, normal muscle twitch interpreted as neurological disease
Scanning the body for sensations that might trigger the next attack
Difficulty distinguishing between a normal sensation and a symptom that signals panic

Sleep Disruption

Insomnia: difficulty falling asleep due to worry about nocturnal panic
Nocturnal panic: waking in the middle of the night with a full panic attack, sometimes without clear trigger
Early morning panic: waking with anxiety and anticipatory worry
Non-restorative sleep: sleeping but waking feeling exhausted
Nightmares related to panic or catastrophic themes

Secondary Depression

Low mood, anhedonia (loss of pleasure), hopelessness
Negative thoughts: "I will never recover," "My life is ruined," "I am broken"
Reduced motivation and energy
Feelings of worthlessness
Suicidal ideation in severe cases
Approximately 50 percent of people with panic disorder develop comorbid major depressive disorder (Kessler et al., 2006)

Reduced Activity and Lifestyle Contraction

Sedentary lifestyle: sitting at home avoiding movement out of fear of triggering an attack
Giving up exercise due to fear that physical exertion will trigger panic
Reduced work productivity or job loss due to panic-related absenteeism or difficulty concentrating
Social withdrawal and isolation: avoiding friends, family, and social events
Increased television, internet, or other passive activities

Functional Impairment

Impairment at work: difficulty concentrating, missing work due to panic or anticipatory anxiety, reduced job performance, demotion, or job loss
Impairment in relationships: partner strain from accommodating avoidance, reduced sexual activity, parenting challenges due to inability to take children places
Impairment in social life: inability to attend events, see friends, or engage in hobbies
Reduced independence: adult relying on parent for transportation, teenager becoming school-refusal, person unable to be alone

Attack-Level Symptoms: The 13 DSM-5 Criteria and Body System Breakdown

This section maps the 13 DSM-5 criteria to body systems for a mechanistic understanding of what is happening during a panic attack.

Cardiovascular System

Pounding heart or accelerated heart rate (tachycardia)

Heart rate climbs from resting 60-100 bpm to 120-160+ bpm within seconds. The sensation is forceful, visible in your chest and throat, and audible in your ears. Adrenaline (epinephrine) surges, triggering the heart to pump faster to send blood to large muscles. This is sympathetic nervous system activation in preparation for fight-or-flight, not a sign of cardiac disease. The sensation is real, but the danger is not.

Chest pain or chest discomfort

A sharp, pinpoint, pressure-like, tight, or dull sensation develops across the chest, localized to one spot, diffuse, or moving around. It is typically lighter than cardiac chest pain and does not radiate in the predictable pattern of heart attack. The pain arises from muscle tension in the chest wall (bracing and hyperventilation), intercostal muscle fatigue (muscles between ribs), and heightened awareness of normal heart sensations amplified by attention and fear.

Feeling heart will burst or sensing imminent cardiac death

A catastrophic thought paired with chest sensations. The pounding heart (which you can feel) combines with the fear symptom (catastrophic interpretation) to create terror. Your amygdala (brain's alarm center) is in high alert, and your prefrontal cortex (rational brain) is temporarily offline. The sensation and the fear feed each other in a vicious cycle.

Respiratory System

Shortness of breath or sensation of choking

You feel as though you cannot get enough air, your lungs will not fill, or the air feels thicker. You may gasp or hyperventilate. A choking sensation is distinct: a physical sensation that something is blocking your throat, preventing swallowing. Hyperventilation causes you to exhale excessive carbon dioxide (CO2), lowering blood CO2 levels. Low CO2 triggers a sensation of breathlessness even though oxygen levels are normal. Anxiety also tightens the muscles in your throat. This is the classic hyperventilation cascade that perpetuates itself.

Sensation of choking

A distinct sensation that your throat is constricted, your tongue is thick, or something is lodged in your throat preventing swallowing. Anxiety and muscle tension affect the pharynx and esophagus. Your throat muscles contract. The sensation is real, though there is no physical blockage. Your parasympathetic nervous system (which controls swallowing and digestion) pauses during panic.

Neurological and Sensory System

Dizziness, lightheadedness, or faintness

The room spins gently, tilts, or feels unstable. Your head feels light or detached. You worry you will faint. True syncope (loss of consciousness) is rare during panic, yet the sensation of impending syncope is vivid and frightening. Hyperventilation lowers CO2, triggering lightheadedness. Adrenaline causes blood vessel constriction and blood redistribution away from your brain (toward large muscles). Derealization adds to the dizziness sensation. All three mechanisms contribute to the vertigo-like sensation.

Numbness or tingling sensations (paresthesia)

Pins-and-needles sensations, tingling, or numbness develop, often around your lips, fingertips, nose, or hands. Sometimes the sensation is one-sided, mimicking a stroke. Hyperventilation causes a drop in blood CO2, raising blood pH (alkalosis). This alters the way calcium and potassium ions function in nerve cells, triggering paresthesia. The sensation is harmless but terrifying because it mimics nerve damage or stroke.

Derealization (world feels unreal, distant, or foggy)

Your surroundings look unreal, flat, or as though you are watching through glass or in a movie. Colors seem muted. People seem far away. Sounds are muffled. Your brain disassociates as a protective reflex. During extreme threat, dissociation buffers you from overwhelming sensations. This is not psychosis; it is a normal stress response and an adaptive survival mechanism.

Depersonalization (feeling detached from your body or watching yourself from outside)

You feel separated from your body. You watch yourself from a distance, as if observing yourself in a movie or from above. Your body feels unreal or robotic. Your limbs feel disconnected or as though they belong to someone else. Your brain is further disassociating as a protective reflex. Your sense of self is temporarily fragmented, a normal and temporary protective mechanism.

Gastrointestinal System

Nausea or abdominal distress

Your stomach churns, tightens into knots, or feels queasy. You may have an urgent need to use the bathroom (nausea, cramping, diarrhea, or urge to urinate). During panic, your parasympathetic nervous system (which controls digestion) pauses. Blood shunts away from your digestive organs toward your muscles. The gut tightens. Adrenaline also stimulates the bowels directly. Your body is preparing for physical action and shuts down non-essential functions like digestion.

Thermoregulatory System

Sweating

Cold, clammy sweat breaks out. Your palms become slick. Your forehead or hairline is damp. Sometimes you experience waves of hot flushes followed by cold chills. The sweat is often cold rather than warm. Adrenaline triggers your sweat glands to activate, cooling your body in preparation for physical exertion. This is an evolutionary response to mobilize the body for survival action.

Chills or heat sensations (hot flushes)

Rapid temperature swings. A hot flush surges across your face and chest, your skin turns red, and then suddenly you feel ice cold. Your spine feels frozen. The sensation lasts seconds and repeats. Blood vessels constrict during the adrenaline surge (causing chills), then dilate as your body attempts to cool itself (causing heat flushes). Adrenaline dysregulates your thermostat temporarily.

Musculoskeletal System

Trembling or shaking

Your hands, arms, legs, or entire body shakes involuntarily. You cannot hold a glass of water steady. Your voice trembles. Your legs feel like jelly. The shaking is visible and uncontrollable. Adrenaline surges trigger muscle fibers to contract rapidly in preparation for fight-or-flight action. Your muscles are bracing for physical action that does not come. Your nervous system is in high alert, and muscles fire in rapid, uncoordinated bursts.

Psychological System

Fear of losing control or going crazy

An overwhelming conviction that you are losing your mind, that your thoughts will spiral beyond your control, or that you are having a psychotic break. You feel your consciousness fragmenting. This fear is magnified by depersonalization and derealization symptoms. Your prefrontal cortex is offline, so your rational voice cannot calm your fear. The fear is intense and feels absolutely true.

Fear of dying

A deep, gut-level certainty that death is imminent. You are convinced you are having a heart attack, stroke, seizure, or some other catastrophic medical event. This catastrophic interpretation feeds the panic. The physical symptoms (racing heart, chest pain, shortness of breath, dizziness) feel like evidence of dying. Your amygdala has declared a full emergency alert.

Disorder-Pattern Symptoms: What Defines the Disorder Beyond Individual Attacks

Symptom Cluster 1: Recurrent Unexpected Attacks and Pattern Over Time

Panic disorder is fundamentally a disorder of recurrence and unpredictability. The person does not have one panic attack; they have multiple attacks clustered over weeks to months.

Acute Phase (Frequent Attacks)

Multiple attacks per week or even multiple per day
Attacks at various times of day: morning, afternoon, evening, or nocturnal (during sleep)
Attacks in various situations: while at work, during rest, while driving, during social situations, or at home alone
Severe functional impairment due to frequency and unpredictability

Partial Remission Phase (Attacks Decrease)

Attacks become less frequent (every 1-2 weeks instead of daily)
Anticipatory anxiety persists even as attack frequency declines
Avoidance behaviors remain entrenched
Functional impairment may persist despite fewer attacks

Full Remission Phase (Possible with Treatment)

Attacks cease or become rare
Anticipatory anxiety resolves
Avoidance behaviors reverse
Return to baseline functioning
Possible through cognitive behavioral therapy (CBT-Panic) or medication (SSRIs)

Relapse Risk (Without Treatment or if Treatment Stops)

Attacks can return if treatment discontinues
Life stress can trigger relapse
Natural waxing and waning occur even with treatment

The pattern matters: two attacks within one month, meeting the DSM-5 criterion of "recurrent." One attack, however severe, does not equal panic disorder.

Symptom Cluster 2: Anticipatory Anxiety and Worry About Attacks

Anticipatory anxiety is the persistent fear between attacks. It often exceeds the disability caused by the attacks themselves.

Core Worry Content

"When will the next attack come?" (temporal worry)
"What if I have an attack at work/while driving/during a meeting?" (situational worry)
"What if I have an attack and nobody is around to help?" (isolation worry)
"What if the next attack is worse?" (escalation worry)
"What if I have a heart attack during the next panic attack?" (catastrophic misinterpretation)

Manifestations

Persistent mental chatter about panic throughout the day
Difficulty concentrating at work or school due to anxiety intrusions
Restlessness and inability to relax
Irritability due to constant vigilance
Sleep disruption: difficulty falling asleep due to worry, or waking early with anxiety
Morning anxiety: waking with dread before anything has happened

The Fear Cycle

Anticipatory anxiety feeds on itself. The person worries about an attack, the worry itself generates anxiety sensations (racing heart, dizziness), those sensations trigger fear ("This is the start of an attack"), which escalates the anxiety, confirming the fear. A person can spend their entire day in a low-grade anxiety state without a full panic attack, living in the anticipation of one.

Symptom Cluster 3: Avoidance and Behavioral Changes

Avoidance is how the disorder perpetuates itself. Each time a person avoids a feared situation and the attack does not occur, they reinforce the false belief that the situation was dangerous and that avoidance prevented the attack. This is interoceptive avoidance: avoiding the sensations themselves, not just external situations.

Situational Avoidance

Avoiding specific places: grocery stores, shopping malls, restaurants, public transportation, highways, crowded venues, enclosed spaces (elevators, airplanes), public bathrooms
Avoiding situations: driving, particularly on highways or alone; sitting in the middle of a row at a movie; standing in lines; exercising
Avoiding activities: giving up sports, stopping travel, declining work opportunities, avoiding dating

Interoceptive Avoidance: Avoiding Body Sensations

Avoiding caffeine (triggers palpitations)
Avoiding hot showers (triggers heat sensation)
Avoiding strenuous exercise (triggers rapid heart rate)
Avoiding certain foods thought to trigger sensations
Avoiding medications other than anxiety meds
Avoiding reading or watching content about health or medical emergencies (triggers health anxiety)

The irony: avoiding these situations and sensations prevents the person from learning that nothing bad actually happens, perpetuating the disorder.

Lifestyle Shrinkage

Quitting jobs or reducing work hours
Staying home instead of leaving
Becoming housebound (extreme agoraphobia co-occurring with panic)
Withdrawing from hobbies, friendships, and social life
Relying on family members or partners for transportation and support
Reducing independence and functioning

Symptom Cluster 4: Safety Behaviors and Maladaptive Coping

Safety behaviors are actions a person takes to prevent or manage a feared panic attack or its consequences. They feel protective in the moment but maintain the disorder long-term.

Companion Requirement

Never going alone
Requiring partner, family member, or friend to accompany them to public places
Asking partner to be present during anticipated anxiety
Experiencing panic when companion is unavailable, creating codependency

Medication Reliance and Checking

Always carrying anti-anxiety medication (even if rarely used)
Frequent checking of heart rate with smartwatch or pulse oximeter
Repeated trips to the doctor for reassurance and cardiac workup
Keeping rescue inhalers, antihistamines, or other medications nearby
Believing that medication presence prevents attacks, when in fact it is a safety cue

Physical Safety Strategies

Sitting near exits or keeping escape routes clear
Avoiding sitting in the middle of a theater row
Choosing aisle seats on airplanes
Staying in positions where they feel they can escape
Holding onto objects or people for perceived stability

Reassurance-Seeking

Repetitive questioning of partners, family, or doctors: "Do you think I am having a heart attack?" "Am I okay?"
Seeking reassurance loops that provide temporary relief but then require more reassurance (the relief reinforces the seeking)
Difficulty accepting reassurance or needing it to be repeated

Use of Substances or Medications

Alcohol use to self-medicate anxiety
Benzodiazepine overuse (if prescribed)
Marijuana or other substances to manage anticipatory anxiety
Over-reliance on prescription sedatives

Avoidance of Stimulation

Avoiding news, health content, or medical shows that trigger health anxiety
Avoiding conversations about panic or anxiety
Avoiding reminders of previous panic attacks

These behaviors reduce anxiety in the short term but prevent extinction learning (the brain learning that the feared outcome does not occur), perpetuating the disorder.

Symptom Cluster 5: Hypervigilance to Internal Sensations

Hypervigilance to body sensations is a hallmark of panic disorder. The person becomes excessively aware of and focused on internal cues.

Heightened Interoceptive Awareness

Noticing every heart palpitation, normal or otherwise
Focusing on breathing and becoming aware of every breath
Noticing normal stomach sensations and interpreting them as signs of illness
Attention narrowing: the rest of the world fades as attention locks onto body sensations

Misinterpretation of Normal Sensations

A normal heart palpitation (everyone has occasional skipped beats) is interpreted as arrhythmia
Normal dizziness upon standing is interpreted as syncope imminent
A muscle twitch is interpreted as neurological disease
A stomach gurgle is interpreted as serious GI illness
Normal fatigue is interpreted as a sign of serious illness

Body Scanning and Catastrophic Predictions

Repeatedly scanning the body for warning signs
Predicting the next attack: "I feel a little dizzy, so the attack will come soon"
Misattributing normal sensations to panic triggers

Secondary Health Anxiety

Repeated doctor visits seeking reassurance
Excessive medical testing and health monitoring
Difficulty trusting medical clearance (ECG is normal, but person remains convinced of heart disease)
Illness anxiety disorder may co-develop alongside panic disorder in some cases

Comorbid Conditions: Symptoms That Often Accompany Panic Disorder

Panic Disorder with Agoraphobia

Agoraphobia is fear and avoidance of situations where escape is difficult or help is unavailable if panic occurs. It is not just fear of open spaces; it is fear of being trapped during a panic attack.

Agoraphobic Symptoms (see PAG #47 for comprehensive coverage)

Fear of public transportation (buses, trains, subways, airplanes)
Fear of open spaces (parking lots, bridges)
Fear of enclosed spaces (elevators, small rooms)
Fear of crowds (standing in line, shopping malls, concerts)
Fear of being alone outside the home
Fear of standing in line or sitting in traffic where escape is difficult
Progressive housebound behavior in severe cases

About 30 to 50 percent of people with panic disorder develop agoraphobia. Agoraphobic avoidance significantly compounds functional impairment.

Panic Disorder with Comorbid Major Depressive Disorder

About 50 percent of people with panic disorder develop major depressive disorder (Kessler et al., 2006). Depression comorbidity indicates more severe panic disorder and worse treatment outcomes.

Depressive Symptoms

Persistent low mood throughout the day, most days
Anhedonia: loss of pleasure in activities once enjoyed (hobbies, social contact, food, sex)
Hopelessness: "I will never get better," "There is no point in trying," "I am broken"
Negative self-concept: shame, self-blame, feelings of worthlessness
Reduced energy and motivation
Difficulty concentrating or making decisions
Sleep disturbance (insomnia or hypersomnia; often comorbid panic-related insomnia)
Changes in appetite (increase or decrease)
Suicidal ideation or behavior

The person may experience morning anxiety (panic), daytime avoidance and anticipatory anxiety, and evening low mood and hopelessness. Depression complicates treatment because it reduces motivation to engage in therapy or exposure exercises.

Other Common Comorbidities Worth Evaluating

When assessing panic disorder symptoms, evaluate for:

Generalized Anxiety Disorder (GAD)

Persistent worry extending beyond panic (worry about money, health, relationships, work performance)
Worry is not just about panic but broadly about life circumstances
Physical tension, restlessness, difficulty concentrating, sleep disturbance
Worry present on most days for 6+ months

Post-Traumatic Stress Disorder (PTSD)

Panic attacks triggered by trauma reminders (sounds, sights, anniversaries)
Flashbacks, nightmares, or hypervigilance related to past trauma
Avoidance of reminders of the trauma
Negative mood and beliefs related to the trauma
Panic attacks may be part of the trauma response, not a separate disorder

Obsessive-Compulsive Disorder (OCD)

Persistent intrusive, unwanted, distressing thoughts (obsessions): "What if I go crazy?" "What if I contaminate my family?"
Repetitive behaviors or mental acts (compulsions) to reduce anxiety: checking, counting, reassurance-seeking
Panic can occur in response to intrusive thoughts
The panic is about the obsessive content, not primarily about panic itself

Social Anxiety Disorder

Panic attacks that occur specifically in social situations (public speaking, eating in front of others, social gatherings)
Fear is primarily about social judgment or embarrassment
Avoidance of social situations
Panic is situational (social), not unexpected and uncued

Specific Phobia

Panic attacks triggered by a specific object or situation (flying, heights, animals, needles)
Anticipatory anxiety and avoidance specific to that object/situation
The panic is about the phobic trigger, not unexpected or uncued

Symptom Variation by Demographic

Women with Panic Disorder

Women with panic disorder tend to report:

More chest pain and throat tightness compared to men
More gastrointestinal symptoms (nausea, cramping, diarrhea)
More dizziness and feeling faint
Hormonal cycle effects: panic symptoms may worsen during luteal phase or perimenopause
Higher likelihood of seeking emergency care (women are more likely to call 911 or go to ER, sometimes appropriately, sometimes due to catastrophic interpretation)
More comorbid depression: women with panic have higher rates of comorbid major depressive disorder

See PAG #8 (Woman Panic Attack Symptoms) for detailed gender-specific information.

Men with Panic Disorder

Men with panic disorder tend to report:

Avoidance of symptom reporting: men are less likely to describe emotional or cognitive symptoms like fear of dying
Presentation as anger, irritability, or aggression: panic anxiety is somatized as anger, especially in workplace or relationship settings
Withdrawal or isolation: men may retreat and hide the attack rather than seek help
Focus on physical symptoms only: describing racing heart and trembling but denying fear or catastrophic thinking
Delayed diagnosis: panic-related anger or irritability is often mistaken for a separate mood problem

Children and Adolescents with Panic Disorder

Young people with panic disorder tend to report:

Somatic complaints (stomach aches, headaches) more than emotional symptoms
School refusal: refusing to attend school due to anticipatory anxiety, becoming school-phobic
Difficulty articulating the experience: children lack words for depersonalization or derealization
Physical restlessness or clinginess to parent during and after attacks
Sleep disruption (panic-related insomnia, nightmares, resistance to sleep)
Separation anxiety: intensified when panic develops

Older Adults with Panic Disorder

Older adults with panic disorder tend to report:

Greater concern about cardiac danger (legitimate due to increased comorbid heart disease and age-related risk)
Atypical presentations: older adults often have atypical panic symptoms (jaw pain, fatigue, shortness of breath without chest pain)
More extensive medical workup (ECG, stress test, cardiac imaging) due to cardiac risk
Medication interactions: SSRIs, blood pressure meds, stimulants, and other medications affect panic presentation
Coexisting medical conditions (diabetes, hypertension, COPD, heart disease) that complicate clinical picture
Possible initial onset triggered by medical illness or medication side effect

Panic disorder in older adults is often underdiagnosed because symptoms are attributed to medical conditions or aging rather than anxiety.

Physical Signs Observable to Others

While panic disorder symptoms are primarily internal and subjective, observers often notice external signs. Recognizing these signs in a loved one or coworker can prompt appropriate support and referral to treatment.

See PAG #28 (Signs of a Panic Attack) for detailed observable signs including breathing changes, skin color changes, trembling, sweating, facial tension, wide eyes, and behavioral signs like sudden urge to leave or clinging.

Common observable signs include:

Sudden rapid or shallow breathing
Trembling or shaking hands or legs
Visible sweating on forehead, palms, or neck
Pale, flushed, or blotchy skin
Wide eyes with tearing up
Gripping chair arms or objects tightly
Sudden request to use the bathroom, leave the room, or get fresh air
Asking repeatedly "Am I okay?" or "Am I dying?"
Difficulty speaking or shaky voice
Sudden withdrawal from activity or conversation
Repeated ER visits or medical workups

Severity Grading and Functional Impairment

Panic disorder severity varies from mild to severe. Severity grading helps clinicians prioritize treatment intensity and helps patients understand their condition.

Mild Panic Disorder

Attack Characteristics

Occasional panic attacks (less than one per month or a few per year)
Mild to moderate symptom intensity during attacks
Attacks last typically 15-30 minutes

Disorder-Pattern Characteristics

Mild anticipatory anxiety: occasional worry about attacks, not constant
Minimal avoidance: person continues most activities but may avoid one or two places
Few safety behaviors
Sleep is mostly unaffected
Mood is generally normal
Work and relationships are largely unaffected

Functional Impairment

Minimal impact on daily functioning
Person continues working, socializing, and maintaining hobbies
No work absences or significant relationship strain
No lifestyle shrinkage

Treatment Prognosis

Highly responsive to treatment
Often responds to psychoeducation alone or brief therapy
SSRIs effective with good tolerability
Recovery likely within weeks to months

Moderate Panic Disorder

Attack Characteristics

Regular panic attacks (one to several per month)
Moderate to severe symptom intensity
Attacks last 20-30 minutes (normal duration)

Disorder-Pattern Characteristics

Significant anticipatory anxiety: person worries multiple times per day about attacks
Moderate avoidance: person avoids specific places (e.g., highways, shopping malls) and situations
Some safety behaviors: carrying medication, needing companion, checking heart rate
Some sleep disruption: occasional insomnia or difficulty falling asleep due to worry
Mild to moderate mood symptoms: occasional low mood or irritability
Some functional impairment in work or relationships

Functional Impairment

Noticeable impact on daily functioning
Work performance affected or occasional absences
Some relationship strain from avoidance accommodation
Some activities reduced or modified (e.g., avoiding solo travel, limiting outdoor activity)
Social withdrawal beginning to emerge

Treatment Prognosis

Responsive to treatment with therapy and/or medication
CBT-Panic 60-80 percent effective at 12-16 weeks
SSRIs effective, though may take 6-8 weeks
Recovery expected within months with consistent treatment

Severe Panic Disorder

Attack Characteristics

Frequent panic attacks (several per week or daily)
Severe symptom intensity: person is convinced during each attack they are dying
Attacks may cluster (multiple in one day) or be continuous (low-grade panic all day)
Nocturnal panic common

Disorder-Pattern Characteristics

Pervasive anticipatory anxiety: person in nearly constant state of worry about attacks
Extensive avoidance: person avoids most public places, leaving home, or specific situations
Multiple safety behaviors: always needs companion, carries multiple medications, frequent ER visits
Significant sleep disruption: insomnia, nocturnal panic, early morning awakening with panic
Comorbid depression common: low mood, hopelessness, anhedonia
Suicidal ideation possible in severe cases with depression

Functional Impairment

Severe impact on daily functioning
Work: job loss, extended absence, inability to concentrate, or complete inability to work
Relationships: significant strain on marriage/partnership, parenting challenges, social isolation
Agoraphobia often present: person may be housebound or near-housebound
Loss of independence: relying on others for basic activities

Treatment Prognosis

Requires intensive treatment: often combines therapy (CBT) with medication (SSRI or combination therapy)
May require psychiatric hospitalization if suicidal ideation
Longer recovery timeline: months to years
Good recovery possible with persistent treatment, but relapse risk higher if treatment stops
Comorbid depression treatment essential for recovery

Symptoms Suggesting Medical Workup or Emergency Evaluation

Not all panic-like symptoms are panic disorder. Some presentations warrant medical evaluation to rule out other conditions.

Red Flags Requiring Emergency Evaluation

Chest pain with cardiac pattern (heavy, crushing, radiating to arm/jaw/back, lasting 20+ minutes)
Fainting or loss of consciousness
Severe shortness of breath at rest (unable to speak full sentences)
Sudden severe headache (worst of life, thunderclap quality)
One-sided weakness or inability to move limbs
Slurred speech or difficulty speaking coherently
Blue lips or cyanosis
First-ever episode of severe symptoms (cannot assume panic)

Presentations Warranting Medical Evaluation (Non-Emergency)

Symptoms lasting longer than 45 minutes without resolution
Back-to-back panic attacks without full recovery between episodes
Focal neurological symptoms (one-sided numbness, vision loss)
Chest pain with exertion
Syncope or presyncope with exertion
Symptoms triggered or worsened by caffeine, stimulants, or new medications

See PAG #17 (Panic Attack vs Heart Attack) for detailed guidance on cardiac red flags.

Symptoms That Point to Other Conditions to Evaluate

When symptoms are new, atypical, or have changed, consider other diagnostic possibilities:

Thyroid Storm (Hyperthyroid Crisis)

Sustained intense heat, excessive sweating, pounding heart, tremor, severe anxiety
High fever (101-105F), confusion
Symptoms sustained over hours to days, not 20-30 minutes
Requires hospitalization and medical emergency management

Hypoglycemia (Low Blood Sugar)

Shakiness, sweating, rapid heartbeat, hunger, confusion, anxiety
Pattern: occurs after fasting, missed meals, or insulin injection
Resolution: rapid resolution (within 15 minutes) after eating carbohydrates
Panic does not respond to food; hypoglycemia does

Cardiac Arrhythmia

Palpitations, fluttering, skipped beats, sometimes syncope
May occur at rest or with exertion
Distinction: ECG will show the arrhythmia; panic cannot be diagnosed on ECG

Pheochromocytoma (Rare Adrenal Tumor)

Episodic severe anxiety, pounding heart, profuse sweating, severe high blood pressure, headache
Episodes last 15-60 minutes (longer than typical panic's 20-30 minutes)
Dramatic blood pressure spikes; 24-hour urine catecholamine testing is diagnostic

Vestibular Disorder (Inner Ear Dysfunction)

True vertigo (room spinning, not lightheadedness), nausea, imbalance, sometimes hearing loss
Symptoms may persist longer than panic

When Symptoms Warrant Treatment: Diagnostic Thresholds

A person should seek professional mental health evaluation if they experience:

2 or more unexpected panic attacks (meeting criterion for panic disorder, even without other symptoms)
1 or more month of persistent anticipatory worry about having another attack (the DSM-5 criterion B feature)
Significant behavioral avoidance (avoiding places, situations, or activities due to panic fear)
Safety behaviors or maladaptive coping (requiring companion, frequent reassurance, substance use to manage anxiety)
Sleep disruption from anticipatory anxiety or nocturnal panic (persistent for weeks)
Depressed mood, anhedonia, or hopelessness (suggesting comorbid depression)
Suicidal ideation (seek immediate mental health support or crisis line)
Functional impairment in work, relationships, or daily life (job impact, relationship strain, withdrawal from activities)
Lifestyle shrinkage or loss of independence (staying home instead of leaving, needing companion, reduced work functioning)

First Steps:

Primary care medical evaluation: ECG, thyroid function (TSH, free T4), blood glucose, complete blood count, blood pressure, medication review
Mental health referral: Ask for referral to psychiatrist, psychologist, or licensed therapist trained in cognitive behavioral therapy for panic (CBT-Panic)
Medication consideration: If treatment recommends SSRI (first-line medication for panic), discuss expected onset (4-6 weeks), early side effects (jitteriness, nausea in week 1-2), and tapering plan
Therapy engagement: CBT-Panic involves psychoeducation, cognitive restructuring, and exposure therapy (including interoceptive exposure: learning that panic symptoms are safe and harmless)

FAQ: Panic Disorder Symptoms

Q: What is the difference between panic attack symptoms and panic disorder symptoms?

A: A panic attack is a discrete 20-30 minute episode with 4+ of 13 DSM-5 symptoms (racing heart, chest pain, shortness of breath, dizziness, numbness, fear of dying, etc.). Panic disorder requires 2+ panic attacks plus at least one month of persistent anticipatory anxiety, behavioral avoidance, or safety behaviors. The attack symptoms are the same; the disorder symptoms (the pattern, the worry between attacks, the avoidance) are what define the disorder. One attack does not equal panic disorder; the sustained pattern does. See PAG #2 (Panic Attack Symptoms) for detailed attack symptom content.

Q: Are panic disorder symptoms the same in men and women?

A: No. Women with panic disorder report more chest pain, throat tightness, and gastrointestinal symptoms. Women are more likely to seek emergency care. Men with panic disorder are more likely to minimize emotional symptoms, present as anger or irritability, and withdraw. Men are less likely to seek help or report fear of dying, leading to delayed diagnosis. See PAG #8 (Woman Panic Attack Symptoms) for detailed gender-specific information.

Q: Can panic disorder cause physical illness?

A: Panic disorder symptoms are caused by your own nervous system (adrenaline, hyperventilation, muscle tension), not by a medical disease. However, panic disorder does not cause lasting physical illness. Panic is not medically dangerous in healthy individuals. That said, unrelenting anticipatory anxiety and avoidance can lead to secondary health problems: sedentary lifestyle increases cardiovascular disease risk, chronic stress increases inflammation, sleep loss affects immunity, and comorbid depression increases health problems. Additionally, panic disorder may unmask or trigger latent medical conditions, and comorbid conditions (thyroid disease, cardiac arrhythmia) may need separate treatment.

Q: What are the early warning signs of panic disorder?

A: Early warning signs include a first panic attack (out of the blue, severe, frightening), followed by days to weeks of worry about having another attack. You may start avoiding places where the first attack occurred. You may experience sleep disruption from worry. You might notice hypervigilance to body sensations (checking heart rate, breathing, or dizziness frequently). Family history of panic disorder or anxiety increases risk. Recognizing these early signs and seeking treatment early (within weeks, not months) improves prognosis.

Q: Can panic disorder symptoms come and go, or is the disorder constant?

A: Panic disorder symptoms typically wax and wane. Attacks may be frequent for weeks, then less frequent for months. Anticipatory anxiety may be intense one week and mild the next, depending on life stress. Some people have months of remission, then experience a relapse. Without treatment, the natural course is variable: some people improve on their own, others remain chronic. With treatment (CBT or medication), symptoms can resolve completely. The key is that untreated panic disorder is unpredictable and often worsens without intervention.

Q: Do panic disorder symptoms get worse with age?

A: Not necessarily. Some people report panic improving with age as they become less worried about catastrophic outcomes and develop better coping skills. Others report it worsening, particularly if comorbid depression develops or medical conditions emerge. Older adults with panic may have more difficulty because of medical comorbidities that complicate the picture (heart disease, diabetes) and medication interactions. Early treatment in younger years improves long-term prognosis.

Q: Can panic disorder cause weight loss or weight gain?

A: Panic disorder can indirectly affect weight through multiple mechanisms: reduced activity and lifestyle shrinkage can lead to weight gain; anhedonia and comorbid depression can reduce appetite and cause weight loss; anxiety itself can suppress appetite; some people overeat as a coping mechanism; SSRI medications can cause weight gain or loss depending on the specific medication. These effects are secondary to the disorder, not direct medical consequences of panic itself.

Q: How do panic disorder symptoms differ from generalized anxiety disorder (GAD)?

A: Panic disorder symptoms are characterized by sudden panic attacks (discrete, peak within minutes, specific symptoms like racing heart and dizziness) plus anticipatory anxiety specifically about panic. The worry is about panic itself: "When will the attack come?" With GAD, anxiety is persistent and broadly focused (worry about work, money, health, relationships, the future) without discrete panic attacks. GAD anxiety is chronic and low-grade; panic is episodic and acute. A person can have both conditions (comorbid panic disorder and GAD). Distinguishing them is important for treatment planning: panic responds well to exposure therapy; GAD responds to worry reduction techniques.

Treatment Implications: Understanding Symptoms as a Guide to Recovery

Understanding the full range of panic disorder symptoms is essential for treatment planning and recovery expectations.

Symptoms Guide the Therapy Approach

If panic attacks dominate: interoceptive exposure (learning that panic sensations are safe)
If anticipatory anxiety dominates: cognitive restructuring of catastrophic thoughts
If avoidance dominates: situational exposure (facing feared places and situations)
If safety behaviors dominate: behavioral experiments to test whether safety behaviors are necessary
If depression dominates: treatment of comorbid depression may be essential for panic recovery

Symptoms Drive Medication Choice

If panic attacks with physiological symptoms dominate: SSRIs (serotonin-modulating antidepressants)
If anxiety sensitivity is high: benzodiazepines for acute management, but SSRIs for chronic treatment (benzodiazepines are for short-term only due to dependency risk)
If comorbid depression: SSRIs are ideal, as they treat both

Symptoms Shape Recovery Expectations

Mild panic: 4-8 weeks of treatment, often full recovery
Moderate panic: 12-16 weeks of treatment, often significant improvement to full recovery
Severe panic with comorbid depression: 6+ months of consistent treatment, recovery possible but with longer timeline

Symptom Tracking Predicts Improvement

Keeping a symptom diary (tracking attack frequency, intensity, anticipatory anxiety level, avoidance, mood) helps you and your therapist monitor progress. Improvement looks like: fewer attacks, reduced intensity, lower anticipatory anxiety, less avoidance, less safety-seeking, improved mood, better sleep, and restored functioning.

Next Steps: From Symptoms to Support

If you recognize panic disorder symptoms in yourself:

Seek medical evaluation: Rule out medical mimics (thyroid disorder, cardiac arrhythmia, hypoglycemia)
Get mental health referral: Ask your doctor to refer you to a psychiatrist or psychologist trained in panic disorder treatment
Request CBT-Panic or medication evaluation: Be direct: "I have panic attacks and anticipatory anxiety. I would like treatment."
Track your symptoms: Use a panic diary to monitor patterns and progress
Know that recovery is possible: Panic disorder is highly treatable with a 60-80 percent remission rate with proper treatment
