Distinguish persistent worry, panic, phobic avoidance, and compulsive rituals, then choose focused therapy and medication using the patient's actual fears.
A patient avoids the train because escape might be difficult during a panic episode. Another avoids the same train because strangers might judge visible trembling. A third boards only after silently repeating a phrase to prevent a feared accident. The location is identical; the feared consequence and the response to it identify different treatment targets.
Ask what is feared and what the person does next
Anxiety is not automatically a disorder. Assess persistence, proportionality to actual danger and cultural context, distress, and interference with ordinary life. Ask when symptoms began, what triggers them, what the patient predicts will happen, and which activities have become restricted. A fear rating alone cannot distinguish generalized anxiety from social anxiety, agoraphobia, or an obsession. [4]

Medical and substance causes belong in the first assessment. Thyroid disease, arrhythmia, hypoglycemia, cardiopulmonary illness, stimulant use, heavy caffeine intake, and alcohol or sedative withdrawal can resemble anxiety. Use the presentation to guide examination and testing. A previous normal emergency evaluation does not prove that every later episode of chest discomfort or faintness has the same cause. [2][3]
Also assess depression, suicide risk, trauma symptoms, substance use, sleep, and bipolar history when relevant to treatment. Several anxiety disorders can coexist. Diagnostic thresholds organize the history; they should not prevent timely support for a person who has substantial symptoms but has not yet met a duration criterion.

Case 4
Show answer and explanations for case 4
A. Panic disorder. (Best answer)
Recurrent unexpected attacks plus persistent maladaptive avoidance satisfy the central disorder-level pattern.
B. A single isolated panic attack only. (Why this does not fit)
The recurrence and prolonged aftermath establish more than one isolated episode.
C. GAD based solely on fear of another attack. (Why this does not fit)
The worry is specifically linked to panic episodes rather than several ordinary life domains.
D. Social anxiety disorder. (Why this does not fit)
Recurrent unexpected attacks are described rather than attacks restricted to feared scrutiny or humiliation.
Takeaway: Panic disorder includes the pattern after the attacks as well as the attacks themselves.
Generalized anxiety disorder involves excessive, difficult-to-control worry about several areas of life on most days for at least six months, with clinically important distress or impairment. Adults need at least three associated symptoms among restlessness, fatigue, concentration difficulty, irritability, muscle tension, and disturbed sleep. Children require only one associated symptom. Worry limited to being judged in social settings is better investigated as social anxiety rather than automatically counted as GAD. [1][17]
A panic attack is an abrupt surge of intense fear or discomfort that peaks within minutes and includes at least four characteristic symptoms. These can include palpitations, sweating, trembling, breathlessness, choking sensations, chest discomfort, nausea, dizziness, chills or heat, paresthesias, derealization or depersonalization, fear of losing control, or fear of dying. A full symptom list is not a reason to ignore objective abnormalities. The rapid peak matters; no rule says every attack and its residual distress must end at exactly 30 minutes. [3]
Panic disorder requires recurrent unexpected attacks and at least a month of persistent concern about further attacks or their consequences, or a maladaptive behavioral change. One attack during a clearly feared speech does not establish panic disorder. Attacks can occur in other disorders, and fewer than four symptoms can still be distressing without fulfilling the full panic-attack symptom definition. [2]
For GAD with marked impairment, offer an evidence-based psychological treatment such as high-intensity CBT or an SSRI-based medication approach according to preference and circumstances. They are not compulsory simultaneous treatments for everyone. Buspirone can be an alternative in selected patients who need scheduled ongoing treatment, but has delayed benefit and does not function as an immediate rescue or prevent benzodiazepine withdrawal. [5][16]
Panic-focused CBT addresses catastrophic interpretation of bodily sensations and avoidance, often including appropriately assessed interoceptive exposure. An SSRI is a common medication option; start cautiously and titrate because early activation can be uncomfortable. Explain delayed benefit, follow-up, and withdrawal precautions. NICE advises against benzodiazepines for panic disorder and limits their GAD use to short-term crises. A routine benzodiazepine bridge should not be presented as an essential part of starting an SSRI. [5]
Identify the kind of avoidance
Agoraphobia centers on situations where escape might be difficult or help unavailable if panic-like or incapacitating symptoms occur. The pattern includes at least two categories among public transport, open spaces, enclosed spaces, queues or crowds, and being outside the home alone. The situations provoke fear, are avoided or endured with distress, and the pattern is usually persistent for at least six months with impairment. Agoraphobia can occur with or without panic disorder. [4]
Social anxiety centers on scrutiny and negative evaluation. A patient may fear blushing, trembling, appearing incompetent, or being rejected during conversation, eating in public, or performance. Persistence, typically at least six months, disproportionate fear, and impairment distinguish the disorder from ordinary nerves. A performance-only pattern is narrower than social fear across many interactions. Individual CBT specifically designed for social anxiety is a preferred initial treatment; an SSRI can be offered when medication is preferred or indicated. [6]
Propranolol may reduce physical symptoms such as tremor or a fast pulse in selected performance situations. That limited symptomatic role does not establish it as a cure for broad social anxiety or the preferred long-term treatment. Check asthma, bradycardia, hypotension, and other contraindications. A sedating benzodiazepine can impair memory, coordination, and performance and should not be assumed to be a harmless alternative. [12][13]
Specific phobia is focused on a particular object or situation, such as dogs, flying, heights, or needles, with immediate fear, avoidance, and meaningful impairment, usually persisting at least six months. Exposure-based treatment helps the patient approach the feared situation gradually and safely. It is not a requirement to experience actual injury or to be surprised by an uncontrolled exposure. Routine long-term medication is not the central treatment. [4][19]
Blood-injection-injury fear can involve a vasovagal fall in blood pressure and fainting. Applied tension may help a patient prone to fainting by countering the pressure drop, alongside appropriate positioning and a supported exposure plan. This differs from treating every anxious sensation with relaxation. Investigate syncope when its features suggest an additional cause. [14]
OCD is defined by function, not tidiness
Obsessions are recurrent intrusive thoughts, urges, or images that cause distress; people often try to suppress or neutralize them. Compulsions are repetitive behaviors or mental acts performed according to rigid rules or in response to an obsession. The act is intended to reduce distress or prevent a feared event, but is excessive or not realistically related to preventing it. Washing and checking are only two examples. Silent counting, reviewing memories, repeated confession, reassurance seeking, and mental cancellation can serve the same function. [7][11]
A repeated checking example
An intrusive doubt about a locked door produces distress.
Repeated checking briefly lowers the distress.
The short-term relief encourages checking the next time uncertainty appears.
ERP changes the response to uncertainty so a ritual is no longer required before ordinary activity can continue.
OCD requires obsessions, compulsions, or both that are time-consuming, often more than an hour daily, or cause significant distress or impairment. The time figure is not a requirement to deny care to someone whose shorter rituals cause major disability. Symptoms must not be better explained by a substance, medical illness, or another disorder. Current classification places OCD among obsessive-compulsive and related disorders, although anxiety is often prominent. [7][18]
Insight varies. Many patients recognize that the fear is excessive, but poor or absent insight can occur. Do not exclude OCD just because the patient is convinced a feared consequence is likely. Evaluate the broader symptom structure and possible psychotic illness rather than using a single ego-dystonic versus ego-syntonic slogan as a diagnostic test. [18]
Disturbing sexual, religious, or harm-related intrusive thoughts are not equivalent to desire or intent. Ask about the person's reaction, rituals, avoidance, actual wishes, planning, and access to means. A distressed person avoiding a loved one for fear of an unwanted thought may have an obsession, while an expressed wish and plan require a different safety response. Do not make either automatic-danger or automatic-safety assumptions from the topic of a thought. [8]

Case 15
Show answer and explanations for case 15
A. Normal conscientious proofreading. (Why this does not fit)
The unrealistic feared consequence and two-hour ritual burden exceed ordinary task checking.
B. OCD with checking compulsions. (Best answer)
Intrusive distress and repetitive neutralization, with substantial time burden, fit the obsession-compulsion pattern.
C. OCPD solely because the patient rereads text. (Why this does not fit)
The ritual serves a feared catastrophic consequence rather than a pervasive valued standard of order and control.
D. GAD without any compulsive behavior. (Why this does not fit)
The specific intrusive belief and neutralizing act are more informative than a general worry label.
Takeaway: Identify what the repetitive act is trying to prevent.
Treat the ritual without abandoning ordinary safety
Exposure and response prevention is a form of CBT. The therapist and patient identify triggers, feared predictions, rituals, and avoidance, then practice manageable exposure while refraining from the ritual. A contamination exercise might involve touching an ordinary household surface and following usual hygiene rather than repeated washing. It should not involve deliberate exposure to a genuine infectious hazard. The goal is learning to tolerate uncertainty and resume life without ritualized neutralization. [8]
Response prevention includes mental rituals. If a patient stops visible checking but silently repeats a protective phrase throughout exposure, the maintaining response may still be present. Likewise, relatives may unintentionally accommodate OCD by repeatedly checking locks, answering the same certainty-seeking question, or reorganizing daily life around rituals. Plan gradual reduction of accommodation with consent, support, and safety assessment rather than blaming the family.
For adults with mild impairment, lower-intensity CBT including ERP may be appropriate. With moderate impairment, a choice between more intensive ERP-based CBT and an SSRI is reasonable. Severe impairment often warrants both. When medication is used, OCD can require a longer trial and higher tolerated doses within appropriate prescribing limits than an initial depression regimen. Do not equate this with automatic dosing above the product maximum. Evaluate a full trial over approximately 12 weeks and track function as well as symptom burden. [8]
SSRIs such as fluoxetine, fluvoxamine, sertraline, or paroxetine are established OCD medication options, with choice guided by age, licensing, interactions, adverse effects, and preference. Clomipramine is generally considered after an adequate SSRI trial is ineffective or poorly tolerated. Its anticholinergic effects, cardiac conduction concerns, interactions, and overdose toxicity require additional attention. A patient who improves on an SSRI but has disabling sexual adverse effects needs a treatment discussion, not an assumption that adherence failure is inevitable.
Before labeling OCD resistant, confirm diagnosis, adherence, medication dose and duration, whether therapy actually included ERP, comorbidities, and ongoing accommodation. NICE places consideration of antipsychotic augmentation after multidisciplinary review and nonresponse to full trials of an SSRI alone, SSRI plus ERP-based CBT, and clomipramine alone. Further CBT is another option; the guideline does not establish an optimal sequence among these specialist options. Antipsychotics are not standard OCD monotherapy, including merely because insight is poor. Children and adolescents need developmentally adapted assessment and treatment, often involving family and appropriate specialist medication monitoring. [8]
Distinguish personality, appearance, possessions, and body-focused behaviors
OCPD is a pervasive pattern of orderliness, perfectionism, and control that sacrifices flexibility and effectiveness across contexts, beginning by early adulthood. Excessive detail, inability to finish a task to an impossible standard, reluctance to delegate, rigid rules, and excessive work can impair relationships and function. The standards are often experienced as appropriate, but patients can still be distressed by the consequences. OCPD is not synonymous with OCD, and the two can coexist. [10][11]
OCD
A patient rereads a message to neutralize an intrusive fear that one incorrect word will cause a catastrophe. Assessment focuses on the obsession, ritual, impairment, and insight.
OCPD
A patient misses many deadlines across work and home because only an exact personal standard is acceptable and delegation feels intolerable. Assessment focuses on the pervasive inflexible pattern.
Body dysmorphic disorder involves preoccupation with a perceived appearance defect that is slight or unobservable to others, together with repetitive behaviors or mental comparison. Mirror checking, camouflage, avoidance, and requests for repeated cosmetic procedures may dominate life. Assess distress, function, and suicide risk. Disorder-focused CBT and, according to severity, an SSRI can help. Suspected BDD warrants mental health assessment before further cosmetic intervention; do not promise that changing the feature resolves the illness. [9][8]
Hoarding disorder involves persistent difficulty discarding possessions because of a perceived need to save them and distress about discarding, leading to clutter that compromises living spaces. Assess fire, fall, sanitation, and housing risks. Distinguish the condition from an organized collection, clutter due to physical disability, and the broader OCPD pattern. Treatment emphasizes hoarding-specific psychological and practical support; a sudden coercive cleanout or a generic SSRI prescription is not a complete plan. [9]
Trichotillomania involves recurrent hair pulling with hair loss, unsuccessful attempts to stop, and distress or impairment. Excoriation disorder involves repeated skin picking causing lesions with similar unsuccessful attempts and impact. Examine for dermatologic causes and complications. Habit-reversal approaches identify triggers and introduce competing responses and environmental changes. These disorders are not automatically treated as contamination OCD, and SSRIs should not be presented as uniformly effective first-line treatment for the core pulling or picking behavior. [9]

Case 26
Show answer and explanations for case 26
A. Generalized anxiety disorder. (Why this does not fit)
Multidomain excessive worry with associated symptoms is not the organizing pattern; enduring control, detail and perfectionism are.
B. Avoidant personality disorder. (Why this does not fit)
Avoidant personality centers on inadequacy and sensitivity to rejection. This pattern is organized around control and standards rather than interpersonal fear.
C. Obsessive-compulsive personality disorder. (Best answer)
The enduring cross-context pattern supplies multiple characteristic features, impairment and early-adult onset. The absence of rituals helps distinguish coexisting OCD rather than defining OCPD by ego-syntonicity alone.
D. Obsessive-compulsive disorder. (Why this does not fit)
No intrusive obsessions or neutralizing compulsions are described. Attention to detail alone does not establish OCD.
Takeaway: OCPD concerns pervasive inflexible standards, not simply repetitive acts.
