Must know

• Symptom Differentiation (Figure 9-1)Anxiety symptoms manifest in two domains: psychological (apprehension, fear, obsession) and physiological (muscle tension, tachycardia, tachypnea, chest tightness, stomach discomfort, restlessness).

  • Anxiety symptoms manifest in two domains: psychological (apprehension, fear, obsession) and physiological (muscle tension, tachycardia, tachypnea, chest tightness, stomach discomfort, restlessness).
  • Normal anxiety is defined as a proportional response to a real external threat that does not impair daily function.
  • Anxiety disorders (pathological anxiety) are defined by excessive responses or threat-free onset combined with significant functional impairment.
  • Medical conditions that mimic anxiety symptoms span cardiovascular (myocardial infarction), respiratory (COPD, pulmonary embolism), and metabolic (hypoglycemia, pheochromocytoma) systems.
  • Pharmacological triggers of anxiety include stimulants, sympathomimetics, theophylline, diphenhydramine (paradoxical excitation in older adults), levodopa, and antipsychotic-induced akathisia.
  • Generalized anxiety disorder requires excessive worry on most days for at least 6 months plus 3 of 6 physical/cognitive symptoms in adults (1 in children), whereas panic attack surges peak within 10 minutes.
• Which of the following symptoms is not consistent with a panic attack?A. Sensation of shortness of breath

  • A. Sensation of shortness of breath
  • C. Fear of dying
• The Diagnostic Pivot LogicNormal anxiety is a reasonable, adaptive response to a real external threat, whereas anxiety disorder requires an excessive response or no external threat plus demonstrable functional impairment.

  • Normal anxiety is a reasonable, adaptive response to a real external threat, whereas anxiety disorder requires an excessive response or no external threat plus demonstrable functional impairment.
  • Gate 1 (Medical Rule-Out): Always rule out physiological mimics first, including hyperthyroidism, pheochromocytoma, COPD, pulmonary embolism, myocardial infarction, and hypoglycemia.
  • Gate 2 (Substance Rule-Out): Evaluate for symptoms starting within 1 month of substance use, intoxication, or withdrawal. Key culprits include theophylline, diphenhydramine, levodopa, stimulants, and withdrawal from alcohol or benzodiazepines.
  • Gate 3 (Stressor Timeline): Symptoms emerging within 3 months of an identified stressor that resolve within 6 months after termination represent adjustment disorder.
  • Gate 4 (Trauma Pivot): Symptoms developing after severe trauma lasting 3 days to 1 month are acute stress disorder (ASD); symptoms persisting greater than 1 month become post-traumatic stress disorder (PTSD).
• Step 1: Normal vs. Pathological AnxietyIs there an actual external threat?

  • Is there an actual external threat?
  • Is the autonomic and emotional response proportional to the threat?
  • Is there significant impairment in social, occupational, or personal functioning?
• Step 2: The 5-Gate Diagnostic FilterNever diagnose a primary psychiatric anxiety disorder without running the patient through the systematic 5-gate filter. Missing an underlying medical crisis or drug toxicity can be fatal.

  • Never diagnose a primary psychiatric anxiety disorder without running the patient through the systematic 5-gate filter. Missing an underlying medical crisis or drug toxicity can be fatal.
  • 1. Gate 1: Rule Out Medical Conditions
  • Assess for medical mimics before considering primary psychiatric illness.
  • Endocrine and metabolic triggers: hyperthyroidism, pheochromocytoma, and hypoglycemia (which triggers sympathoadrenal epinephrine release).
  • Cardiopulmonary triggers: myocardial infarction, COPD, and pulmonary embolism.
  • 2. Gate 2: Rule Out Substance and Medication Triggers

  Safety. Never diagnose a primary psychiatric anxiety disorder without running the patient through the systematic 5-gate filter. Missing an underlying medical crisis or drug toxicity can be fatal.

• Compare and DistinguishNormal Anxiety vs. Anxiety Disorder

  • Normal Anxiety vs. Anxiety Disorder
  • Think: Normal anxiety is adaptive and proportional; anxiety disorder is excessive and disabling.
  • Priority: Differentiate real external threat from pathologically generated hyperarousal.
  • Boards are testing: Functional impairment as the defining threshold for psychiatric diagnosis.
  • Acute Stress Disorder vs. Post-Traumatic Stress Disorder
  • Think: The 1-month calendar cutoff determines the diagnostic label.

  Board trap. Test writers love presenting an older adult with acute anxiety who was recently started on diphenhydramine or theophylline, or a patient with new-onset panic who is actually experiencing hypoglycemia or hyperthyroidism. Selecting a primary anxiety disorder or prescribing an SSRI

• C) MethotrexateWhy It Is Correct: Methotrexate is an immunosuppressive disease-modifying antirheumatic agent that does not cause central nervous system stimulation or autonomic hyperarousal, making it least likely to induce anxiety symptoms.

  • Why It Is Correct: Methotrexate is an immunosuppressive disease-modifying antirheumatic agent that does not cause central nervous system stimulation or autonomic hyperarousal, making it least likely to induce anxiety symptoms.
  • Why the Other Choices Are Wrong:
  • A: Theophylline is a xanthine bronchodilator with central stimulant properties that commonly causes tachycardia, tremors, and severe anxiety.
  • B: Diphenhydramine has significant anticholinergic effects that frequently trigger paradoxical central nervous system excitation, restlessness, and anxiety in older adults.
  • D: Levodopa increases central dopamine levels, which routinely causes agitation, anxiety, and neuro-psychiatric side effects.
• C) HyperglycemiaWhy It Is Correct: Hyperglycemia does not acutely stimulate the sympathoadrenal system to produce acute panic or autonomic anxiety symptoms, whereas hypoglycemia triggers an immediate catecholamine surge.

  • Why It Is Correct: Hyperglycemia does not acutely stimulate the sympathoadrenal system to produce acute panic or autonomic anxiety symptoms, whereas hypoglycemia triggers an immediate catecholamine surge.
  • Why the Other Choices Are Wrong:
  • A: Chronic obstructive pulmonary disease causes acute hypoxia and hypercapnia, which directly trigger respiratory panic and intense autonomic anxiety.
  • B: Myocardial infarction induces severe autonomic hyperarousal and acute apprehension, often described as a feeling of impending doom.
  • D: Hypoglycemia triggers a massive epinephrine release, causing acute tachycardia, diaphoresis, tremors, and severe anxiety.
• D) I am terrified that another attack will happen so I avoid leaving my apartment aloneWhy It Is Correct: Panic disorder requires recurrent, unexpected panic attacks that occur spontaneously out of the blue. Attacks that occur predictably after a specific emotional argument are situational responses rather than unexpected panic.

  • Why It Is Correct: Panic disorder requires recurrent, unexpected panic attacks that occur spontaneously out of the blue. Attacks that occur predictably after a specific emotional argument are situational responses rather than unexpected panic.
  • Why the Other Choices Are Wrong:
  • B: Depersonalization and derealization are characteristic psychological symptoms during a panic attack.
  • C: Abrupt onset peaking within 10 minutes out of the blue is the cardinal feature of unexpected panic attacks.
  • D: Persistent anticipatory worry and behavioral avoidance lasting 1 month or more are core criteria for panic disorder.
• D) The diagnosis cannot be made until symptoms have persisted for at least 6 monthsWhy It Is Correct: Symptoms occurring between 3 days and 1 month following exposure to a severe traumatic event meet the specific time frame for acute stress disorder.

  • Why It Is Correct: Symptoms occurring between 3 days and 1 month following exposure to a severe traumatic event meet the specific time frame for acute stress disorder.
  • Why the Other Choices Are Wrong:
  • A: The diagnosis of post-traumatic stress disorder requires symptoms to persist for greater than 1 month, regardless of trauma severity or type.
  • C: Adjustment disorder is used for non-trauma stressors or trauma reactions that do not meet full symptom criteria for ASD or PTSD.
  • D: PTSD can be diagnosed as soon as symptom duration exceeds 1 month; waiting 6 months is unnecessary.
• Diagnostic Branching Hierarchy (Figure 9-2)Gate 1 Medical Rule-Out: Before diagnosing a primary psychiatric disorder, rule out medical conditions such as hyperthyroidism, pheochromocytoma, COPD, pulmonary embolism, myocardial infarction, and hypoglycemia.

  • Gate 1 Medical Rule-Out: Before diagnosing a primary psychiatric disorder, rule out medical conditions such as hyperthyroidism, pheochromocytoma, COPD, pulmonary embolism, myocardial infarction, and hypoglycemia.
  • Gate 3 Adjustment Disorder: Adjustment disorder with anxious mood requires symptom onset within 3 months of an identifiable stressor and resolution within 6 months after the stressor or its consequences end.
  • Gate 4 Trauma Timeline: Trauma-related symptoms lasting 3 days to 1 month after exposure represent acute stress disorder. Symptoms persisting for greater than 1 month represent post-traumatic stress disorder (PTSD).
  • Gate 4 GAD Criteria: Generalized anxiety disorder (GAD) requires excessive, uncontrollable worry on most days for at least 6 months, accompanied by at least 3 of the WATCHERS physical/cognitive symptoms (only 1 symptom required in children).
  • Gate 4 Panic Disorder Criteria: Panic disorder requires recurrent, unexpected panic attacks peaking within 10 minutes, followed by at least 1 month of persistent concern about additional attacks or significant maladaptive behavior change.
  • Gate 4 OCD Criteria: Obsessive-compulsive disorder (OCD) requires intrusive obsessions or repetitive compulsions that are time-consuming, taking up at least 1 hour per day, or cause severe functional impairment.
• Step 1: Primary Medical Assessment (Gate 1)What it is: Evaluating whether physical illness or altered lab parameters directly cause the anxiety presentation.

  • What it is: Evaluating whether physical illness or altered lab parameters directly cause the anxiety presentation.
  • Check TSH for hyperthyroidism, EKG and cardiac enzymes for myocardial infarction, blood glucose for hypoglycemia, and urinary catecholamines for pheochromocytoma.
  • Never assume acute anxiety or panic in an older adult or new-onset case is primary psychiatric without obtaining vital signs, physical exam, and basic lab work.
  • Mistaking physical symptoms of hypoxia or respiratory distress from COPD or pulmonary embolism for a primary panic attack.

  Board trap. Mistaking physical symptoms of hypoxia or respiratory distress from COPD or pulmonary embolism for a primary panic attack.

  Safety. Never assume acute anxiety or panic in an older adult or new-onset case is primary psychiatric without obtaining vital signs, physical exam, and basic lab work.

  Safety. Abrupt discontinuation of alprazolam or lorazepam can precipitate severe withdrawal seizures, delirium, and autonomic crisis.

• Step 3: Stressor and Adjustment Assessment (Gate 3)What it is: Evaluating emotional or behavioral reactions to identifiable psychosocial stressors.

  • What it is: Evaluating emotional or behavioral reactions to identifiable psychosocial stressors.
  • Timelines: Onset occurs within 3 months of the stressor. Symptoms must resolve within 6 months once the stressor or its consequences end.
  • Distress is out of proportion to the stressor severity and causes functional impairment, but does not meet full criteria for another primary disorder.
• Step 4: Primary Anxiety and Related Disorders Screening (Gate 4: The Big Five)SSRIs (sertraline, paroxetine) or SNRIs plus trauma-focused psychotherapy. Prazosin (3 to 15 mg) at bedtime targets trauma nightmares. Avoid benzodiazepines in PTSD.

  • Trauma spectrum:
  • Acute stress disorder: Symptoms emerge within 3 days to 1 month following exposure to actual or threatened death, serious injury, or sexual violence.
  • Post-traumatic stress disorder: Symptoms persist for greater than 1 month post-trauma, spanning intrusion, avoidance, negative mood/cognitions, and hyperarousal.
  • SSRIs (sertraline, paroxetine) or SNRIs plus trauma-focused psychotherapy. Prazosin (3 to 15 mg) at bedtime targets trauma nightmares. Avoid benzodiazepines in PTSD.
  • Social and phobic spectrum:
  • Social anxiety disorder: Marked fear of scrutiny or embarrassment in social or performance situations lasting at least 6 months.

  Board trap. A panic attack is a specifier, not a standalone DSM-5-TR diagnosis.

  • Classic distractor: Selecting panic attack as the primary Axis I diagnosis.
• Substance-Induced Anxiety vs Primary Anxiety DisorderThink: Substance-induced is directly linked to drug ingestion, toxicity, or withdrawal; primary anxiety occurs independently of substance use.

  • Think: Substance-induced is directly linked to drug ingestion, toxicity, or withdrawal; primary anxiety occurs independently of substance use.
  • Priority: Rule out recent chemical ingestion or withdrawal before starting psychotropics.
  • Boards are testing: Onset within 1 month of substance use or withdrawal defines substance-induced anxiety.

• Social Anxiety Disorder vs Generalized Anxiety DisorderThink: Social anxiety is fear of judgment/scrutiny in social settings; GAD is pervasive worry across multiple everyday life domains.

  • Think: Social anxiety is fear of judgment/scrutiny in social settings; GAD is pervasive worry across multiple everyday life domains.
  • Priority: Identify the trigger stimulus.
  • Boards are testing: Social anxiety centers on embarrassment and scrutiny; GAD centers on uncontrollable worry about finances, health, family, and performance over 6 months.
  • Classic distractor: Calling social performance anxiety GAD because the patient reports somatic symptoms like sweating and tachycardia.
• Medical and Pharmacological Mimics (Table 9-1)Always order baseline laboratory work, including TSH to rule out hyperthyroidism, blood glucose to evaluate hypoglycemia, and a urine drug screen before initiating psychotropics.

  • Medical conditions and pharmacological agents must be systematically evaluated and ruled out before confirming a primary anxiety disorder diagnosis.
  • Suspect pheochromocytoma when a patient presents with paroxysmal episodes of severe hypertension, headache, diaphoresis, and sudden panic attacks due to catecholamine hypersecretion.
  • Distinguish medication-induced akathisia from worsening primary anxiety. Akathisia is an extrapyramidal motor restlessness caused by dopamine-blocking antipsychotics or antiemetics that patients experience as extreme internal anxiety.
  • Always order baseline laboratory work, including TSH to rule out hyperthyroidism, blood glucose to evaluate hypoglycemia, and a urine drug screen before initiating psychotropics.
  • Central stimulants such as dextroamphetamine, methylphenidate, caffeine, and OTC decongestants like pseudoephedrine directly provoke autonomic hyperarousal and acute anxiety symptoms.
  • Severe cardiovascular and pulmonary conditions including myocardial infarction, pulmonary embolism, and COPD produce hypoxia and hypercapnia that directly mimic acute panic.

  Board trap. Distinguish medication-induced akathisia from worsening primary anxiety. Akathisia is an extrapyramidal motor restlessness caused by dopamine-blocking antipsychotics or antiemetics that patients experience as extreme internal anxiety.

  Safety. Suspect pheochromocytoma when a patient presents with paroxysmal episodes of severe hypertension, headache, diaphoresis, and sudden panic attacks due to catecholamine hypersecretion.

• Pharmacological Mimics of AnxietySympathomimetics and stimulants increase noradrenergic and dopaminergic neurotransmission. Dextroamphetamine, methylphenidate, cocaine, caffeine, and pseudoephedrine stimulate alpha and beta receptors, producing tachycardia, tremors, diaphoresis, and acute fear.

  • Sympathomimetics and stimulants increase noradrenergic and dopaminergic neurotransmission. Dextroamphetamine, methylphenidate, cocaine, caffeine, and pseudoephedrine stimulate alpha and beta receptors, producing tachycardia, tremors, diaphoresis, and acute fear.
  • Anticholinergics and sedating antihistamines produce paradoxical central effects. Diphenhydramine causes anticholinergic restlessness, cognitive disorientation, and paradoxical anxiety, particularly in geriatric patients.
  • Dopamine receptor antagonists induce motor restlessness. Akathisia from antipsychotics or prokinetic antiemetics presents as subjective internal anxiety and objective motor inability to sit still.
  • Sedative-hypnotic withdrawal causes severe rebound autonomic hyperactivity. Abrupt cessation of alcohol or benzodiazepines results in GABA hypofunction, producing tremors, severe anxiety, delirium, and seizures.
• Medical Condition Mimics by SystemCardiovascular conditions present with intense chest distress. Myocardial infarction, cardiac arrhythmias, angina, and heart failure cause autonomic hyperactivity, air hunger, and a profound feeling of impending doom.

  • Cardiovascular conditions present with intense chest distress. Myocardial infarction, cardiac arrhythmias, angina, and heart failure cause autonomic hyperactivity, air hunger, and a profound feeling of impending doom.
  • Respiratory conditions induce hypoxia and hypercapnia. COPD, pulmonary embolism, and severe asthma trigger central fight-or-flight circuits due to impaired oxygenation.
  • Neurological conditions alter central anxiety networks. Delirium, complex partial seizures, vestibular dysfunction, and stroke alter cerebral regulation, producing acute agitation, disorientation, and anxiety.

  • Up to 75 percent of GAD patients present in primary care or medical specialty clinics with somatic complaints rather than chief complaints of anxiety.
• Generalized Anxiety Disorder Rating ScaleAdminister the GAD-7 at baseline and follow-up visits to track symptom reduction alongside evidence-based psychotherapy or pharmacotherapy.

  • What it is: The GAD-7 is a brief 7-item self-report tool developed by the creators of the PHQ-9 to screen for and monitor generalized anxiety disorder severity.
  • Why boards care: The exam tests your ability to interpret standardized score ranges to determine clinical severity and evaluate treatment response.
  • A score of 5 to 9 represents mild anxiety. A score of 10 to 14 represents moderate anxiety. A score of 15 to 21 indicates severe anxiety. Scores of 10 or greater warrant further diagnostic evaluation and treatment planning.
  • Administer the GAD-7 at baseline and follow-up visits to track symptom reduction alongside evidence-based psychotherapy or pharmacotherapy.

  • Abrupt cessation of long-term benzodiazepine therapy causes a severe, life-threatening withdrawal syndrome that mirrors alcohol withdrawal. Symptoms range from mild rebound insomnia, anxiety, and tachycardia to severe grand mal seizures, delirium, autonomic collapse, and coma.
  • Benzodiazepine Pharmacokinetics and Dosing Equivalence:
  • Diazepam: Fastest onset of action; long half-life of 20 to 80 hours due to active metabolites.
  • Alprazolam: Rapid onset of action; short half-life of 12 to 15 hours. Short half-life drives frequent rebound anxiety, rapid physical dependence, and high risk for withdrawal seizures if stopped abruptly.

  Board trap. Do not initiate SSRIs at full standard doses in panic disorder or GAD. Patients with panic disorder are hypersensitive to somatic sensations. Initial activation or jitteriness (frequently seen with fluoxetine) leads patients to prematurely reject long-acting medications. Always s

• Fitzgerald Sample Question: Benzo OnsetOnset of Action: Oral benzodiazepines generally take effect within 15 to 30 minutes, but diazepam has the fastest onset of action due to high lipophilicity, combined with the longest half-life of 20 to 80 hours.

  • Onset of Action: Oral benzodiazepines generally take effect within 15 to 30 minutes, but diazepam has the fastest onset of action due to high lipophilicity, combined with the longest half-life of 20 to 80 hours.
  • High-Risk Short-Acting Agent: Alprazolam possesses a rapid onset and the shortest half-life of 12 to 15 hours, predisposing patients to rapid tolerance, severe rebound anxiety, and rapid withdrawal onset.
  • Dosing Equivalencies: Standardized potency equivalencies require knowing that alprazolam 0.5 mg equals clonazepam 0.25 mg, diazepam 5 mg, and lorazepam 0.75 mg to 1 mg.
  • Withdrawal Onset Timelines: Withdrawal symptoms manifest within 1 to 2 days for short-acting benzodiazepines and within 5 to 10 days for long-acting benzodiazepines.
  • Alprazolam Tapering Rules: Outpatient tapering of alprazolam must proceed slowly at a rate no faster than 0.25 mg per week to prevent severe withdrawal, delirium, and seizures.
  • Diazepam Substitution Strategy: An evidence-based alternative taper substitutes an equivalent total daily dose of diazepam, followed by a dose reduction of 10% to 20% every 1 to 2 weeks as tolerated.
• Key Clinical SignpostsFirst-line maintenance pharmacotherapy for generalized anxiety disorder, panic disorder, and social anxiety disorder consists of SSRIs or SNRIs. Benzodiazepines are restricted to brief 2 to 3 week bridging during initial antidepressant setup.

  • Benzodiazepine withdrawal mechanism targets GABA receptors and directly mirrors alcohol withdrawal. Abrupt cessation triggers severe autonomic hyperarousal, diaphoresis, tremors, tachycardia, delirium, coma, and potentially fatal grand mal seizures.
  • Choosing to stop short-acting benzodiazepines abruptly when a patient reports side effects or asks to discontinue therapy. Never stop short-acting agents suddenly. Taper alprazolam by no more than 0.25 mg per week, or substitute an equivalent dose of diazepam before tapering.
  • Prescribing benzodiazepines as long-term monotherapy or using them in post-traumatic stress disorder (PTSD). Clinical guidelines specifically flag benzodiazepines as ineffective and harmful in PTSD.
