histrionic personality disorders - Nursing Case Study
Pathophysiology
• Primary mechanism: Histrionic personality disorder (HPD) involves dysregulation in emotional processing, potentially linked to altered neurotransmitter activity, such as serotonin and dopamine imbalances, which can affect mood and reward pathways, contributing to emotional instability and attention-seeking behaviors.
• Secondary mechanism: Dysfunctional attachment patterns during early childhood, often due to inconsistent or inadequate parental attention, may lead to a developed reliance on external validation and excessive emotional expression as a means to secure attention and approval.
• Key complication: These mechanisms can result in significant interpersonal difficulties, as individuals with HPD may struggle to maintain stable, meaningful relationships, potentially leading to increased stress and decreased overall well-being.

Section 1
During a routine follow-up appointment, the patient presents with increased emotional distress and reports that her interpersonal relationship issues have intensified, impacting her ability to perform at work. Upon initial assessment, the patient is visibly agitated and expresses concern about her ability to maintain her role in an upcoming theatrical production. Her excessive emotionality is evident, and she frequently shifts topics, highlighting her struggles with maintaining focus. The patient also reports a recent episode where she felt overwhelmed with anxiety, during which she took her prescribed lorazepam. However, she admits to using it more frequently than recommended in the past week due to escalating stress.
Clinically, the patient’s vital signs indicate a blood pressure of 150/95 mmHg and a heart rate of 110 bpm, suggesting increased sympathetic nervous system activity possibly linked to heightened anxiety levels. These findings raise concerns about potential cardiovascular strain if her emotional dysregulation and anxiety are not effectively managed. Furthermore, her recent reliance on lorazepam could indicate developing tolerance, necessitating a careful reassessment of her anxiety management plan. Given her role as a professional actress, her occupation places additional demands on her emotional and psychological resilience, complicating her treatment plan.
The healthcare team considers adjusting her medication regimen to better address both her anxiety and emotional instability. A possible increase in fluoxetine dosage or the introduction of cognitive-behavioral therapy (CBT) is discussed to provide her with healthier coping mechanisms and improve her ability to regulate emotions. Additionally, the team emphasizes the importance of regular monitoring for any adverse effects of medication changes, especially given her profession's high stress and her need for effective emotional modulation. The primary goal is to enhance her functioning and well-being, allowing her to maintain her professional commitments without compromising her mental health.
Section 2
Following the initial assessment, the healthcare team decides to carefully monitor the patient's response to a slight increase in her fluoxetine dosage while initiating cognitive-behavioral therapy (CBT) sessions aimed at equipping her with better stress management techniques. Over the next two weeks, the patient attends bi-weekly CBT sessions, focusing on developing healthier coping strategies for her anxiety and emotional instability. During these sessions, she learns to identify cognitive distortions and practices grounding techniques, which help her manage acute episodes of stress more effectively.
At a follow-up appointment, the patient reports a modest improvement in her ability to concentrate and a slight reduction in the frequency of her anxiety episodes. However, she mentions experiencing occasional dizziness and mild nausea, prompting the healthcare team to explore these symptoms further. Her blood pressure has stabilized to 140/90 mmHg, and her heart rate to 95 bpm, indicating a partial reduction in sympathetic nervous system activity. Despite these improvements, the patient admits to continuing her increased use of lorazepam, raising concerns about potential dependency.
The healthcare team decides to conduct a comprehensive assessment of her current medication regimen and its interactions. Lab results reveal mildly elevated liver enzymes, which could suggest early hepatic strain potentially linked to the increased lorazepam use. This finding necessitates a reevaluation of her anxiety management strategy, considering the risk of medication overuse and its physiological implications. The team discusses the possibility of introducing non-benzodiazepine anxiolytics and reinforcing CBT techniques to mitigate dependency risks while ensuring her emotional and psychological demands are sufficiently managed. This approach aims to support her professional obligations without further compromising her health, setting the stage for the next steps in her treatment journey.
Section 3
New Complications:
Following the adjustment in her treatment plan, the patient presents at her next follow-up with new symptoms that warrant immediate attention. She reports persistent fatigue, occasional episodes of confusion, and a noticeable increase in irritability. Her vital signs show a heart rate of 102 bpm and blood pressure of 150/95 mmHg, suggesting a possible rebound in sympathetic nervous system activity. Additionally, a physical examination reveals slight jaundice, prompting the healthcare team to order a liver function panel to assess the extent of hepatic involvement.
Lab results indicate a further elevation in liver enzymes, with ALT at 85 U/L and AST at 90 U/L, confirming the suspicion of hepatic strain. The combination of these findings suggests that the patient's liver may be under increased stress, potentially exacerbated by her continued lorazepam use. In light of these developments, the healthcare team prioritizes addressing the risk of benzodiazepine dependency and its implications for her liver health.
The team decides to taper the lorazepam cautiously while introducing buspirone as a non-benzodiazepine alternative to manage anxiety, reducing the potential for hepatic damage. Concurrently, the CBT sessions are intensified to enhance her coping mechanisms and support her transition away from reliance on benzodiazepines. This multifaceted approach aims to stabilize her physiological status while maintaining her ability to function professionally and personally, preparing her for the next phase of her treatment journey.
Section 4
As the treatment plan progresses with the introduction of buspirone and the tapering of lorazepam, the patient initially shows some improvement in her anxiety levels. However, during a routine follow-up, she reports new symptoms that raise concerns. She describes experiencing palpitations more frequently, especially during periods of stress, and mentions having difficulty concentrating at work. Her partner also notes that she seems more withdrawn and less expressive, which is a departure from her typically vibrant personality. Upon examination, her vital signs reveal a persistent tachycardia with a heart rate of 110 bpm and slightly elevated blood pressure at 145/92 mmHg.
These symptoms prompt the healthcare team to consider the possibility of buspirone inducing side effects such as increased heart rate and the challenge of managing her anxiety without exacerbating her hepatic condition. To address these concerns, the team orders an ECG to evaluate cardiac function and checks her electrolytes to rule out any imbalances contributing to her symptoms. The ECG comes back normal, but her electrolyte panel reveals a mild hyponatremia with sodium levels at 132 mEq/L, which could explain some of her confusion and concentration difficulties.
In light of these findings, the healthcare team decides to adjust her medication regimen further by slightly reducing the buspirone dosage and monitoring her electrolyte levels more closely. They also explore additional non-pharmacological interventions, such as mindfulness-based stress reduction, to provide her with more tools to manage anxiety without relying solely on medication. This approach aims to balance her mental health needs with her physical well-being, highlighting the importance of interdisciplinary coordination and careful monitoring in managing complex cases like hers.
Section 5
As the healthcare team continues to monitor the patient, they notice a subtle yet significant change in her status over the next few weeks. Despite the adjustment in her buspirone dosage, the patient reports persistent palpitations and a newly developed intermittent tremor, particularly noticeable in her hands. These symptoms are accompanied by a persistent sense of restlessness and irritability, causing concern for potential drug-induced side effects or another underlying condition. Her partner also mentions that she has become increasingly forgetful, often misplacing items or struggling to recall recent conversations, further complicating her ability to function effectively at work.
During a follow-up appointment, her vital signs reveal a slight improvement in heart rate, now at 102 bpm, but her blood pressure remains elevated at 148/94 mmHg. The persistence of tachycardia and heightened blood pressure prompts the team to delve deeper into potential causes. A repeat electrolyte panel shows that her sodium levels have improved slightly to 134 mEq/L, but new findings indicate a mild hypokalemia with potassium levels at 3.2 mEq/L. The combination of these symptoms and lab results raises suspicion of a possible interaction between her medications and her body's electrolyte balance.
The team decides to implement a more comprehensive intervention strategy. This involves consulting a cardiologist to rule out any cardiac complications and collaborating with a dietitian to address her electrolyte imbalances through dietary modifications. They also emphasize the importance of adherence to mindfulness practices introduced earlier, as these techniques offer a non-pharmacological means of reducing her anxiety and improving her concentration. The interdisciplinary approach underscores the complexity of managing her histrionic personality disorder with concurrent physical symptoms, ensuring a holistic approach to her care.
