Should a Psychiatric Mental Health Medical Provider (PMHMP) disclose consideration of a cluster B personality disorder diagnosis to a 71-year-old female with a history of chaotic relationships, impulsivity, and failure to take blame?

Disclosure of Cluster B Personality Disorder Diagnosis to Elderly Patients

Clinicians should disclose consideration of a Cluster B personality disorder diagnosis to a 71-year-old female patient with lifelong patterns of chaotic relationships, impulsivity, and failure to take blame, as early diagnosis and transparent communication can reduce individual suffering and improve treatment outcomes. 1

Understanding the Clinical Context

When considering whether to disclose a potential Cluster B personality disorder diagnosis to an elderly patient, several factors must be weighed:

1. Diagnostic validity: Personality disorders represent persistent patterns over time affecting self-identity and interpersonal functioning 1. The patient's lifelong history of chaotic relationships, impulsivity, and failure to take blame aligns with classic Cluster B features.

2. Age considerations: While personality disorders are often diagnosed earlier in life, the persistence of these patterns into older age suggests a true personality disorder rather than a transient condition or age-related change.

3. Treatment implications: Disclosure enables informed consent for appropriate treatment approaches, which may include psychotherapy options specifically developed for personality disorders 1.

Benefits of Diagnostic Disclosure

• Improved understanding: Helps the patient make sense of lifelong patterns of interpersonal difficulties
• Treatment engagement: Enables targeted therapeutic approaches like Dialectical Behavior Therapy (DBT), which has demonstrated efficacy 1
• Reduced suffering: Early diagnosis and appropriate treatment can reduce individual suffering 1
• Enhanced therapeutic alliance: Transparency builds trust, particularly important with personality disorders where interpersonal relationships are already challenging 2

Addressing Stigma Concerns

While stigma is a valid concern, consider these approaches:

• Normalize the diagnosis: Present personality disorders as patterns of coping that developed over time
• Focus on specific behaviors: Discuss concrete examples of how these patterns have affected the patient's life
• Emphasize treatment potential: With appropriate treatment, many patients show improvement over time 1
• Use person-first language: Avoid labeling the patient as "a borderline" or "a narcissist"

Practical Approach to Disclosure

1. Choose appropriate timing: Select a session when there is adequate time for discussion and processing
2. Use clear, non-judgmental language: "Based on the patterns you've described throughout your life, I believe you may have what we call a Cluster B personality disorder"
3. Connect to patient's experience: "This helps explain the difficulties you've experienced in relationships and emotional regulation"
4. Discuss treatment options: Present evidence-based approaches like DBT, Mentalization-Based Therapy, or other effective psychotherapies 1
5. Set realistic expectations: Explain that while personality patterns are enduring, specific symptoms and functioning can improve with treatment

Special Considerations for Elderly Patients

• Life review perspective: Frame the diagnosis as helping to make sense of lifelong patterns
• Treatment modifications: Consider age-appropriate adaptations to standard treatments
• Comorbidities: Assess for common comorbid conditions like depression, anxiety, or substance use disorders, which occur at high rates (83%, 85%, and 78% respectively) 1
• Medication considerations: While no medications have FDA approval specifically for personality disorders, certain medications may help with specific symptoms 1

Potential Pitfalls to Avoid

• Assuming it's "too late": Avoid the misconception that personality disorders cannot be treated in elderly patients
• Overmedication: Avoid relying solely on pharmacotherapy, as psychotherapy remains the primary treatment 1
• Diagnostic overshadowing: Don't attribute all symptoms to personality disorder without considering other conditions
• Therapeutic nihilism: Maintain hope and communicate that improvement is possible with appropriate treatment 1

By approaching diagnosis disclosure with sensitivity, clarity, and an emphasis on treatment options, clinicians can help elderly patients with longstanding personality disorder symptoms gain insight and access appropriate care.
