Panic Disorder
An India-adapted guide to assessing recurrent unexpected panic attacks, excluding acute medical causes, and arranging evidence-based psychological or prescribing care safely.
Summary
Panic disorder is characterised by recurrent unexpected panic attacks together with continuing concern about further attacks, worry about their consequences, or maladaptive changes in behaviour. A panic attack is a rapid surge of intense fear or discomfort with symptoms such as palpitations, sweating, trembling, breathlessness, chest discomfort, nausea, dizziness, chills or heat, altered sensation, derealisation, fear of losing control or fear of dying. An attack can occur in many psychiatric and medical conditions and does not by itself establish panic disorder. The clinician must determine whether episodes are unexpected, recurrent and followed by a sustained change while excluding substances, medicines, physical illness and another mental disorder. [PAN-1] [PAN-2]
Many patients first seek help in emergency or general medical settings because symptoms resemble myocardial ischaemia, arrhythmia, asthma, hypoglycaemia or neurological disease. Acute assessment must therefore be proportionate to the presentation rather than dismissive. Once dangerous alternatives are excluded, clear explanation and timely follow-up can reduce repeated investigation and avoidance. Current guidelines supports self-help for milder illness and CBT or an antidepressant for more impairing adult panic disorder, chosen through shared decision-making. Indian professional guidance also describes panic-focused CBT. current guidelines licensing statements are United Kingdom-specific and must not be copied into Indian prescribing. This educational guide provides no individual diagnosis or dose, remains reviewed and is has been reviewed by the MedNext Clinical Team. [PAN-1] [PAN-2]
How Common Is It?
Panic attacks occur more often than panic disorder because attacks can accompany acute stress, other anxiety disorders, depression, trauma-related illness, substance use and physical disease. Estimates of panic disorder differ according to diagnostic criteria, age, sex, interview method, healthcare setting and whether agoraphobia is included. The Indian Psychiatric Society guideline reports an international lifetime range, but that range is not a nationally representative prevalence estimate for contemporary India and should not be presented as one. No source used in this draft supplies a robust current rate for every Indian state, language or rural and urban population. [PAN-2]
The practical burden includes repeated emergency visits, cardiology consultations, missed work or examinations, avoidance of exercise, reluctance to travel alone and progressive restriction of daily life. Some people stop using buses, metros, markets or lifts because escape feels difficult, developing agoraphobic avoidance. Others repeatedly check pulse, carry unnecessary rescue items or require a relative to accompany them. Stigma may produce purely physical descriptions, while high out-of-pocket costs can magnify the consequences of repeated tests. Clinicians must hold two truths together: most panic attacks are not medical catastrophes, yet a new or atypical episode can represent one. A prevalence statistic cannot determine the probability of acute coronary syndrome, arrhythmia or another emergency in an individual patient. Service planning should measure local presentations, impairment, referral access and treatment completion rather than importing a foreign headline number. [PAN-1] [PAN-3]
Risk Factors
Panic disorder does not have a single necessary cause. Familial vulnerability, anxiety sensitivity, catastrophic interpretation of bodily sensations, chronic stress and prior panic attacks can contribute. An initial episode may occur during illness, sleep deprivation, stimulant use, bereavement or another stressful period; subsequent monitoring of pulse, breathing or dizziness can make ordinary fluctuations feel threatening. Avoidance and safety behaviours provide immediate relief but prevent corrective learning. Reassurance seeking, repeated medical testing and a relative's constant presence may therefore become part of the maintaining cycle even when they began as understandable attempts to help. [PAN-2]
Caffeine, nicotine, energy products, cocaine, amphetamines, cannabis in some users, alcohol withdrawal and sedative withdrawal can precipitate panic-like episodes. Medicines that increase adrenergic symptoms or alter metabolic state should be reviewed without presuming causation. Depression, other anxiety disorders, trauma-related illness and substance-use disorders are important comorbidities and can increase risk or complicate recovery. Pregnancy, the postpartum period, thyroid disease, respiratory illness and cardiac disease change the assessment rather than automatically causing panic disorder. Social adversity, unsafe housing, debt, discrimination and violence can produce genuine threat and require practical intervention. It is poor practice to attribute panic to weak character or to blame a family. A clinically useful formulation connects the episode, bodily cues, feared catastrophe, attention, escape, reassurance, anticipatory anxiety and functional restriction while keeping medical and safeguarding alternatives visible. [PAN-1] [PAN-2]
Diagnosis
History
Ask the patient to narrate the first and most recent episodes in sequence: setting, onset, peak, duration, bodily and cognitive symptoms, whether the attack was expected, and what happened afterwards. Establish frequency, nocturnal episodes, continuing worry, behavioural change, agoraphobic avoidance and functional impairment. Ask about chest pain, exertion, syncope, seizure features, pregnancy, physical disease, medicines, caffeine, alcohol and other substances. Assess depression, mania, psychosis, trauma, self-harm, family history and previous tests or treatment.
Examination
During an acute episode, record observations and perform a focused examination guided by the differential. Assess cardiovascular, respiratory, neurological and metabolic features rather than relying on the patient's age or anxiety history. Once stable, complete a mental-state examination covering affect, thought content, perception, cognition, insight and risk. Observe hyperventilation or safety behaviours without provoking symptoms deliberately.
Investigations
No laboratory test confirms panic disorder. ECG, glucose, pregnancy testing, blood tests, toxicology, respiratory assessment or other investigations should be selected for the presentation and local acute-care pathway. Current guidelines advises minimum investigations necessary to exclude acute physical problems in an emergency presentation, not zero investigation and not an indiscriminate battery. Screening scales may monitor symptoms but do not replace a structured diagnostic consultation. Diagnosis requires recurrent unexpected attacks and a sustained consequence, not a single cued attack. [PAN-1] [PAN-2]
Differential Diagnosis
Acute coronary syndrome, arrhythmia, pulmonary embolism, asthma, pneumothorax, anaphylaxis, hypoglycaemia, seizure, vestibular illness, anaemia, thyroid disease and less common endocrine causes can produce overlapping symptoms. The probability depends on age, risk factors, onset, exertional relationship, observations, examination and associated features; prior panic disorder does not immunise a patient against physical illness. Syncope is not typical loss of consciousness from panic and requires its own assessment. Hyperventilation-related tingling can occur during panic, but focal neurological deficit, persistent confusion, cyanosis, fever or significant hypoxia points elsewhere. [PAN-1]
A panic attack can occur within social anxiety, specific phobia, agoraphobia, PTSD, OCD, depression, mania, psychosis, substance intoxication or withdrawal. Panic disorder is distinguished by recurrent unexpected attacks and continuing concern or behavioural change. In specific phobia, attacks are predictably tied to a circumscribed trigger. In social anxiety, feared scrutiny is central. Agoraphobia involves fear across settings where escape or help may be difficult and may coexist with panic disorder. PTSD adds trauma-linked intrusions and avoidance; OCD adds obsessions and compulsions. Medication adverse effects, excess caffeine and withdrawal must be considered explicitly. Current violence or unsafe living conditions can cause episodic intense fear without representing unexpected panic. Diagnostic humility is essential when symptoms are new, atypical, exertional, prolonged or accompanied by abnormal physical findings. [PAN-1] [PAN-2]
Management
In an acute presentation, ensure safety, assess airway, breathing, circulation and observations, and investigate credible physical emergencies. Communicate calmly, reduce crowding when feasible and explain what is being checked. Once serious causes have been excluded, describe panic symptoms without saying they are imaginary. Avoid repeated unstructured reassurance; provide written information and arrange follow-up. A patient should not be instructed to rebreathe into a paper bag because an unrecognised medical cause and hypoxia could be worsened. If risk assessment identifies suicidality, psychosis, intoxication, withdrawal or safeguarding concerns, manage those pathways directly. [PAN-1]
For mild to moderate adult panic disorder, current guidelines includes evidence-based self-help with review. For moderate to severe or persistent illness, panic-focused CBT is a core treatment. Therapy builds an individual formulation, tests catastrophic interpretations, reduces safety behaviours and avoidance, and may use carefully planned interoceptive and situational exposure. It is delivered by a suitably trained practitioner, not improvised by provoking symptoms without consent. Antidepressant treatment can be considered for adults after shared decision-making when indicated, while psychological treatment has durable benefit. Agree goals such as resuming transport, exercise or independent attendance and track function as well as attacks. Address agoraphobia, depression, substance use and physical disease. Review non-response by checking diagnosis, adherence, actual therapy content, continuing substances, adverse effects and social barriers before declaring treatment resistance. Indian services must adapt the pathway to available trained personnel without claiming that generic counselling is equivalent to panic-focused CBT. [PAN-1] [PAN-2]
Prescribing Information
Any medicine decision requires a confirmed assessment and an appropriately qualified prescriber. Current guidelines states that antidepressants are the longer-term pharmacological option with an evidence base for adult panic disorder, but its named licensing information applies to the United Kingdom at the time of amendment. Indian clinicians must verify current Central Drugs Standard Control Organisation information, approved indications, state or institutional formulary, interactions, age, pregnancy or breastfeeding, physical illness, overdose risk, affordability and patient preference. This guide intentionally omits drug selection, dose, titration and taper schedules and must not be used to start, share or alter treatment. [PAN-1]
Explain delayed benefit, possible early activation, common adverse effects, interaction risk, adherence and discontinuation symptoms before treatment. Early review is important when suicidality, marked agitation, possible bipolarity or poor follow-up is present. Current guidelines advises against benzodiazepines for panic disorder because longer-term outcomes are less favourable and also advises against sedating antihistamines or antipsychotics as treatment for the disorder. Alcohol, opioids and other sedatives can make benzodiazepine use particularly dangerous. Someone taking a dependence-forming medicine regularly should not stop abruptly from online advice; arrange a clinician-led plan. The 2017 Indian professional guideline discusses pharmacological choices, but it predates this draft and does not replace current product information or individual review. Monitor response, functioning, adverse effects and emerging mania, and secure medicines when overdose risk is relevant. [PAN-1] [PAN-4]
When to Refer
Use emergency medical care for persistent or high-risk chest pain, abnormal observations, serious arrhythmia, severe breathlessness, hypoxia, syncope, seizure, focal deficit, pregnancy-related concern, poisoning or another acute physical presentation. Use urgent mental-health care for active suicidal intent, a recent serious attempt, psychosis, mania, delirium, severe intoxication or withdrawal, profound self-neglect or inability to maintain safety. The immediate destination should match the dominant risk; a medically unstable patient should not be sent only to a counselling clinic. [PAN-1] [PAN-3]
Refer to psychiatry or an appropriately trained psychological service for diagnostic uncertainty, substantial agoraphobic restriction, complex comorbidity, pregnancy-related complexity, substance dependence, high self-harm risk, failure of two adequately delivered interventions or need for a specialist medicine plan. Current guidelines places specialist review after significant symptoms persist despite more than one treatment type, while the exact Indian route depends on local capacity. Options may include a Health and Wellness Centre, primary health centre, District Mental Health Programme service, medical-college psychiatry unit, private specialist or emergency department. Verify whether panic-focused CBT is actually offered. Handover should include attack pattern, physical findings and tests, agoraphobia, risks, substances, medicines, previous treatment, patient preference and barriers to attendance. Maintain follow-up while referral is pending, because avoidance can itself make clinic attendance difficult. [PAN-1] [PAN-3]
Red Flags
A prior diagnosis of panic disorder must never become a reason to ignore new pathology. Red flags include crushing or exertional chest pain, haemodynamic instability, serious ECG abnormality, oxygen desaturation, unilateral leg swelling with acute breathlessness, anaphylaxis, severe asthma, syncope, seizure, persistent altered consciousness, focal neurological signs, fever with confusion and marked metabolic disturbance. Symptoms that are different from the patient's established pattern, last unusually long, start during exertion or occur with abnormal examination findings deserve fresh assessment. Do not make the patient exercise or hyperventilate as an exposure exercise until relevant medical contraindications have been considered. [PAN-1]
Psychiatric red flags include suicidal intent or planning, escalating self-harm, command hallucinations, severe agitation, mania, delirium, dangerous intoxication or withdrawal and inability to care for self or dependants. Ask privately about violence, coercion and whether contacting family is safe. Sudden deterioration after a medication change, markedly reduced need for sleep with increased energy, severe inner restlessness or escalating sedative use requires prompt review. Document the patient's words, access to means, physical findings, capacity considerations, medicines, substances, protective factors and transfer plan. Do not leave an acutely unsafe person alone, send a severely symptomatic patient to drive, or discharge them with only breathing advice. After a negative emergency work-up, communicate what was excluded, what remains uncertain and how follow-up will occur rather than simply writing anxiety. [PAN-3] [PAN-5]
Indian Clinical Context
Panic symptoms may be described in somatic terms, and stigma or language differences can obscure fear of recurrence. Ask how the patient understands the episode and explain the formulation in their preferred language. With consent, relatives can support follow-up and reduce accommodation, but family presence should not prevent private assessment of self-harm, substance use or abuse. Repeated emergency investigations create substantial out-of-pocket costs, yet cost pressure must not justify under-investigating credible acute disease. A written summary of prior findings, typical symptoms and agreed red flags can improve continuity without labelling all future attacks as benign. [PAN-3]
MoHFW operational guidance supports identification, psychosocial intervention, referral and follow-up within community and primary-care services, but it does not ensure that every facility offers panic-focused CBT or specialist prescribing. The Mental Healthcare Act, 2017 provides rights relevant to dignity, confidentiality, capacity, access and emergency treatment. current guidelines is a United Kingdom guideline; its treatment evidence is useful, while its licensing, service and referral assumptions are not automatically Indian rules. Indian Psychiatric Society guidance is a professional consensus resource and must be interpreted alongside current law, medicine information and local scope. Travel, examination pressure, migration, unsafe work and discrimination may be real contributors and need practical help. Teleconsultation can improve access if privacy, clinician competence, emergency planning and digital exclusion are addressed. [PAN-1] [PAN-2] [PAN-3] [PAN-5]
NMC Competency Mapping
Within NMC CBME 2024, panic disorder supports integrated learning across psychiatry, internal medicine, emergency care, pharmacology, community medicine, communication and professionalism. At Know level, learners should describe the rapid symptom surge of a panic attack and the additional recurrence and sustained consequence required for panic disorder. At Know How level, they should distinguish expected from unexpected attacks, panic disorder from agoraphobia, and psychiatric symptoms from cardiac, respiratory, neurological, endocrine, metabolic and substance-related alternatives. They should explain catastrophic misinterpretation, interoceptive attention, avoidance and the rationale for panic-focused CBT. [PAN-1] [PAN-2] [PAN-6]
At Show How level, learners should take a chronological episode history, examine a patient with chest symptoms safely, select focused investigations, assess suicide and substance risk, and communicate a negative acute work-up without dismissing distress. Simulation can assess a structured handover and shared explanation of CBT or prescribing options. At Perform level, clinical activity remains supervised and within local scope. Reading a guide does not authorise independent exposure exercises, prescription or emergency discharge. Assessment should reward consent, confidentiality, safe family involvement, interpreter use, documentation and recognition of diagnostic uncertainty. This mapping is educational and does not assert that one page completes a named NMC competency. The NMC document defines training outcomes rather than a panic-disorder treatment pathway. [PAN-6]
Key Exam Pearls for NEET PG
A panic attack is a symptom episode; panic disorder requires recurrent unexpected attacks plus continuing concern, feared consequences or maladaptive behavioural change. Cued attacks occur in specific phobia, social anxiety and other disorders. Agoraphobia concerns feared settings where escape or help may be difficult and can coexist with panic disorder. No laboratory marker confirms the psychiatric diagnosis. New chest pain, abnormal observations, syncope, seizure, hypoxia or focal deficit requires a medical differential even in a patient with previous panic. Hyperthyroidism, arrhythmia, hypoglycaemia, substances and withdrawal are classic mimics. [PAN-1] [PAN-2]
High-yield management is calm acute assessment followed by explanation and continuity; for ongoing adult disorder, evidence-based self-help, panic-focused CBT and appropriately selected antidepressant treatment are recognised options according to severity and preference. CBT includes work with catastrophic interpretations, safety behaviours and exposure, not generic reassurance alone. Benzodiazepines, sedating antihistamines and antipsychotics are not the routine current guidelines treatment answers for panic disorder. A person taking sedatives regularly should not stop abruptly. For non-response, revisit diagnosis, comorbidity, substances, adherence and whether treatment was adequately delivered before escalating. In an Indian question, do not copy UK licensing claims: verify the contemporary Indian label and local formulary. Acute medical instability or suicidality takes priority over a screening score, breathing exercise or outpatient referral. [PAN-1] [PAN-4]
Frequently Asked Questions
Does having one panic attack mean that a person has panic disorder?
No. A panic attack can occur during acute stress, another anxiety disorder, depression, trauma-related illness, substance use, withdrawal or physical disease. Panic disorder requires recurrent unexpected attacks and a continuing period of concern about further attacks, worry about consequences or maladaptive behavioural change. The clinician must also assess medical and substance-related explanations. A first episode with chest pain, syncope, severe breathlessness, abnormal observations or neurological symptoms needs appropriate acute medical assessment rather than an immediate psychiatric label.
Can a normal ECG prove that chest symptoms were only a panic attack?
No. An ECG is one part of an assessment and its meaning depends on timing, symptoms, risk factors, examination and the suspected condition. A normal tracing does not by itself exclude every cardiac, respiratory, metabolic or neurological cause. Clinicians choose further tests according to the presentation and local pathway. Once serious alternatives have been reasonably excluded, clear explanation and follow-up are useful, but future symptoms that are new, exertional, prolonged or associated with syncope, hypoxia or abnormal findings require reassessment.
Why does panic-focused CBT sometimes include exercises that reproduce bodily sensations?
Panic-focused CBT may use carefully planned interoceptive exposure to help a person learn that feared sensations can be tolerated and do not inevitably mean catastrophe. Exercises are chosen collaboratively within a formulation, with attention to physical health, consent and clinician competence. They are not a dare and should not be copied unsupervised from a webpage. Chest disease, syncope, pregnancy-related concerns or another contraindication may alter the plan. Therapy also addresses catastrophic interpretations, avoidance and safety behaviours and links practice to functional recovery.
Are benzodiazepines the best long-term treatment because they can act quickly?
No. Current guidelines advises against benzodiazepines for treatment of panic disorder because longer-term outcomes are less favourable, and dependence, withdrawal, impaired driving and dangerous interactions with alcohol, opioids or other sedatives are important concerns. Evidence-based CBT and appropriately prescribed antidepressant treatment are established longer-term options for adults after assessment and shared decision-making. Anyone already taking a benzodiazepine regularly should not stop suddenly based on online information; withdrawal can be serious and requires a clinician-led plan. Overdose, breathing difficulty, severe drowsiness, confusion or seizure needs urgent help.
