Obsessive-Compulsive and Related Disorders Practice Questions

Q: In which condition is psychosurgery considered as a last resort treatment?

Severe Obsessive-Compulsive Disorder. ***Severe Obsessive-Compulsive Disorder*** - Psychosurgery (e.g., **anterior cingulotomy**, **capsulotomy**) is considered for individuals with **severe, refractory OCD** who have not responded to conventional treatments. - This intervention aims to disrupt specific neural circuits implicated in OCD, such as the **corticostriatothalamocortical (CSTC) loop**. *Severe Generalized Anxiety Disorder* - While GAD can be debilitating, standard treatments like **psychotherapy (CBT)** and **pharmacotherapy (SSRIs, SNRIs)** are generally effective. - Psychosurgery is not typically considered for GAD, as less invasive and established treatments carry significantly lower risks. *Severe Depression* - For severe, treatment-resistant depression, **electroconvulsive therapy (ECT)** and **transcranial magnetic stimulation (TMS)** are more common and established interventions. - Psychosurgery is rarely, if ever, used for severe depression due to ethical concerns and the availability of less invasive options. *Severe Phobia* - Severe phobias primarily respond to **exposure therapy** and **cognitive behavioral therapy (CBT)**. - These therapies directly target the learned fear response and are highly effective without the need for invasive procedures.

Q: An 18-year-old girl presents with a circumscribed bald patch. There is no evidence of organic disease. What is the most likely diagnosis?

Trichotillomania (Hair-Pulling Disorder). ***Trichotillomania (Hair-Pulling Disorder)*** - This condition is characterized by the **recurrent pulling out of one's hair**, resulting in noticeable hair loss or **bald patches**. - The description of a **circumscribed bald patch** without evidence of organic disease in an 18-year-old girl is highly suggestive of trichotillomania, especially given that organic causes of hair loss have been ruled out. *Depression* - While depression can be a **comorbid condition** with trichotillomania, it does not directly cause a circumscribed bald patch. - Depression is a **mood disorder** primarily characterized by persistent sadness, loss of interest, and other emotional and physical symptoms. *OCD* - **Obsessive-compulsive disorder** (OCD) involves intrusive thoughts (obsessions) and repetitive behaviors (compulsions). - Although trichotillomania can share some characteristics with OCD (e.g., repetitive behavior), it is classified as a distinct **body-focused repetitive behavior disorder** in the DSM-5, not OCD itself. *Phobia* - A phobia is an **anxiety disorder** defined by an intense and irrational fear of a specific object or situation. - Phobias do not directly cause **physical symptoms** like bald patches; their primary manifestation is avoidance and panic in the presence of the feared stimulus.

Q: Which personality disorder is most commonly associated with Obsessive-Compulsive Disorder (OCD)?

Anankastic Personality Disorder. ***Anankastic Personality Disorder (Obsessive-Compulsive Personality Disorder)*** - Anankastic Personality Disorder is the **ICD-10 classification** for what is known as **Obsessive-Compulsive Personality Disorder (OCPD)** in the DSM-5. - **Important distinction**: OCD and OCPD are **separate disorders** - OCD is an anxiety disorder with intrusive thoughts and compulsions, while OCPD is a personality disorder characterized by rigid perfectionism and need for control. - OCPD is the **most commonly comorbid personality disorder** with OCD, though most people with OCD do not have OCPD and vice versa. - Individuals with OCPD show a pervasive pattern of **preoccupation with orderliness**, perfectionism, and mental and interpersonal control, at the expense of flexibility, openness, and efficiency. *Borderline Personality Disorder* - Characterized by **instability in interpersonal relationships**, self-image, affects, and marked impulsivity. - While it can be comorbid with anxiety disorders, its core features are distinct from the rigid and perfectionistic traits of OCPD. *Narcissistic Personality Disorder* - Involves a pervasive pattern of **grandiosity**, a need for admiration, and a lack of empathy. - These traits are distinct from the compulsive behaviors and perfectionism seen in OCD and OCPD. *Histrionic Personality Disorder* - Defined by a pattern of **excessive emotionality** and attention-seeking behavior. - This presentation is quite different from the rigid, controlling, and overly conscientious nature associated with OCD.

Q: What term describes repetitive, intrusive thoughts that cause significant distress or anxiety?

Obsession. ***Obsession*** - An **obsession** is defined by the presence of **recurrent and persistent thoughts, urges, or images** that are experienced as intrusive and unwanted, causing significant anxiety or distress. - These thoughts are often recognized as products of one's own mind, and individuals typically attempt to ignore, suppress, or neutralize them. *Phobia* - A **phobia** is an intense, irrational fear of a specific object or situation that poses little or no actual danger. - Unlike obsessions, phobias are typically related to external stimuli and do not primarily involve intrusive thoughts. *Compulsion* - A **compulsion** is a repetitive behavior (e.g., hand washing, checking) or mental act (e.g., praying, counting) that an individual feels driven to perform in response to an obsession. - Compulsions are often aimed at preventing or reducing anxiety or distress, or preventing some dreaded event or situation. *Anxiety* - **Anxiety** is a general term for a feeling of worry, nervousness, or unease, typically about an event or something with an uncertain outcome. - While obsessions cause anxiety, "anxiety" itself is a broad emotional state, not specifically the intrusive thoughts described.

Q: A patient presents with compulsive hair pulling resulting in irregular patchy hair loss. What is the most likely diagnosis?

Trichotillomania. ***Trichotillomania*** - This condition is characterized by **recurrent, irresistible urges to pull out hair**, typically resulting in **noticeable hair loss**. - The resulting patchy hair loss is often **irregular** and can occur in various areas, aligning with the patient's presentation. *Alopecia areata* - This is an **autoimmune condition** that causes smooth, **well-demarcated patches of hair loss**, not typically associated with compulsive pulling. - It usually presents with a sudden onset of hair loss without any preceding trauma or manipulation. *Telogen effluvium* - This condition involves **widespread hair thinning** due to a disturbance in the hair growth cycle, often triggered by stress or illness. - It does not involve compulsive hair pulling and typically results in increased hair shedding rather than patchy hair loss. *Tinea infection* - Also known as **ringworm**, this is a fungal infection that can cause **scaly, itchy patches of hair loss**, sometimes with inflammation and broken hairs. - While it can cause patchy hair loss, it is characterized by dermatological signs of infection (e.g., scaling, erythema) and not compulsive hair pulling.

Q: Which disorder is characterized by fear of contamination, counting behaviors, and having to check and recheck?

Obsessive-compulsive disorder. ***Obsessive-compulsive disorder*** - This disorder is precisely characterized by repetitive, intrusive thoughts (obsessions) like **fear of contamination** and repetitive behaviors (compulsions) like **counting** and **checking** performed to reduce anxiety associated with these thoughts. - The individual feels compelled to perform these rituals to prevent a dreaded event or situation, even if they recognize the irrationality of their actions. *Panic disorder* - This disorder involves recurrent, unexpected **panic attacks** that cause intense fear and physical symptoms such as palpitations, shortness of breath, and dizziness. - It does not primarily involve obsessions about contamination or compulsive checking behaviors. *Agoraphobia (without panic attacks)* - This condition involves significant anxiety about being in places or situations from which escape might be difficult or embarrassing, or where help might not be available in case of incapacitating or embarrassing symptoms. - It is often associated with fear of public transportation, open spaces, enclosed places, standing in line, or being in a crowd, and does not typically involve contamination fears or repetitive checking. *Generalized anxiety disorder (GAD)* - GAD is characterized by persistent and excessive worry about a variety of daily life events or activities, such as work, finances, or health. - While it involves chronic anxiety, it does not typically manifest with specific obsessions like contamination or compulsive behaviors such as counting and checking.

Q: Kleptomania is classified as a/an?

None of the options. ***None of the options*** - **Kleptomania** is classified as an **Obsessive-Compulsive and Related Disorder** in the **DSM-5**, not as an impulse control disorder (which was its DSM-IV classification). - The condition is characterized by recurrent failure to resist urges to steal objects not needed for personal use or monetary value, with increasing tension before the act and relief or gratification afterward. - The reclassification reflects the **compulsive nature** of the behavior and phenomenological similarities with OCD, including repetitive behaviors and difficulty resisting urges. *Impulse control disorder* - This was the **DSM-IV classification** but is now **outdated**. - In DSM-5, kleptomania was moved to the Obsessive-Compulsive and Related Disorders category to better reflect its clinical phenomenology. *Anxiety disorder* - **Anxiety disorders** are primarily characterized by excessive fear, worry, or apprehension, which is not the core feature of kleptomania. - While anxiety may precede or follow an episode of stealing, it is not the primary driving pathology. *Mood disorder* - **Mood disorders** involve significant disturbances in emotional state, such as persistent sadness in depression or elevated mood in bipolar disorder. - The defining feature of kleptomania is the irresistible urge to steal, not a primary mood disturbance.

Q: Which of the following statements about kleptomania is true?

Kleptomaniacs steal from various sources, not just stores.. ***Kleptomaniacs steal from various sources, not just stores.*** - Individuals with kleptomania feel an urge to steal items regardless of their personal value or usefulness, and this can occur in various settings, including **homes, workplaces, and public places**, not exclusively retail stores. - The compulsion is driven by the **tension relief** associated with the act of stealing itself, rather than the acquisition of specific items from particular locations. - This is the most accurate statement as kleptomania is **not location-specific**. *Men are more likely to present with kleptomania at a later age than women.* - Kleptomania is reported to be **more prevalent in females** than males (approximately 3:1 ratio), with typical onset in **adolescence or early adulthood**. - There is **no consistent evidence** to suggest that men present at a significantly later age compared to women. *Kleptomania typically does not develop from adolescent theft.* - While this statement has some truth to it (most adolescent theft is **conduct disorder**, not kleptomania), the onset of true kleptomania **can occur in adolescence**. - However, kleptomania is diagnostically **distinct** from adolescent antisocial behavior or conduct disorder theft, which is driven by different motivations (peer pressure, need, rebellion). - The statement is considered false because kleptomania's **initial manifestation** can occur during adolescent years, even though it differs from typical adolescent theft behaviors. *Men are more likely to face legal consequences for kleptomania.* - There is **no strong evidence** that gender significantly determines legal consequences for kleptomania. - Legal outcomes depend more on **frequency of theft, value of items stolen, prior criminal record**, and local law enforcement practices rather than gender. - Both men and women with kleptomania face legal risks when caught stealing.
