Zorluk: KolayPersonality Disorders

A 26-year-old woman is evaluated in the outpatient clinic for emotional instability. She reports a long history of chronic feelings of emptiness, recurrent superficial self-harm, and frantic efforts to prevent her friends from abandoning her. She states that her mood frequently shifts from intense sadness to rage, often multiple times within the same day based on minor perceived slights. The patient is currently prescribed fluoxetine for depressive symptoms but demands an immediate switch to phenelzine, a medication she read about online. When the physician hesitates, she becomes intensely angry and devalues the physician's competence. Which of the following statements regarding this patient's diagnosis and management are accurate? (Select 3)

  1. The patient's presentation is most consistent with borderline personality disorder.Cevap
  2. Dialectical behavior therapy is the most appropriate long-term psychotherapeutic intervention.Cevap
  3. Immediate initiation of the requested medication risks precipitating serotonin syndrome.Cevap
  4. D
    The patient's brief mood shifts indicate bipolar depression, which is appropriately managed with SSRI monotherapy.
  5. E
    Fluoxetine should be abruptly discontinued to allow starting the monoamine oxidase inhibitor tomorrow.
  6. F
    The patient should be diagnosed with a brief psychotic disorder due to the rapidly shifting nature of her symptoms.

Cevap

The correct statements recognize the clinical diagnosis of borderline personality disorder, identify dialectical behavior therapy as the appropriate primary intervention, and correctly identify that starting an MAOI immediately after an SSRI risks life-threatening serotonin syndrome.
The clinical vignette describes a patient with classic features of borderline personality disorder (BPD), including frantic efforts to avoid abandonment, chronic feelings of emptiness, recurrent self-harm, severe emotional lability, and splitting behavior (demonstrated by her sudden devaluation of the physician when her demands are not met). The most evidence-based, first-line psychological treatment for BPD is dialectical behavior therapy (DBT), which focuses on mindfulness, distress tolerance, and emotional regulation. Pharmacologically, the patient demands phenelzine, a monoamine oxidase inhibitor (MAOI). Because she is currently taking fluoxetine, a selective serotonin reuptake inhibitor (SSRI), prescribing an MAOI without a mandatory 5-week washout period is strictly contraindicated due to the high risk of developing serotonin syndrome, a potentially fatal condition.

Adım Adım Çözüm

1
Analyze the patient's clinical signs and interpersonal patterns.
The patient exhibits chronic emptiness, fear of abandonment, recurrent self-harm, emotional lability (mood reactivity), and splitting (devaluing the physician).
These are the classic DSM-5 criteria for borderline personality disorder (BPD).
2
Determine the most appropriate standard of care for the identified condition.
Dialectical behavior therapy (DBT) is selected as the optimal management strategy.
DBT is the well-established, first-line psychotherapeutic treatment for BPD, focusing on emotional regulation and distress tolerance.
3
Evaluate the patient's pharmacological request (switching from fluoxetine to phenelzine immediately).
The request is identified as highly dangerous and contraindicated.
Combining an SSRI (fluoxetine) with an MAOI (phenelzine) or switching between them without an adequate washout period (5 weeks for fluoxetine) triggers serotonin syndrome.

Anahtar Kavram
