Dissociative disorder - Nursing Case Study
Pathophysiology
• Primary mechanism: Dissociative disorders primarily involve a disruption in the integrated functions of consciousness, memory, identity, or perception due to overwhelming stress or trauma, leading to a fragmentation of mental processes.
• Secondary mechanism: The hippocampus and amygdala may show altered activity or structure, impacting memory processing and emotional regulation, which can exacerbate dissociative symptoms.
• Key complication: Patients may experience significant functional impairment, affecting daily activities and interpersonal relationships, due to the detachment from reality or identity confusion.

Section 1
During the initial assessment, the patient, Ms. Jane Doe, exhibits signs that suggest her dissociative disorder is impacting her daily functioning more severely than initially perceived. She reports that the frequency of her dissociative episodes has increased, occurring several times a week and lasting longer than before. These episodes often leave her feeling confused and exhausted, with gaps in her memory extending up to several hours. Her ability to focus on her work as a graphic designer has been compromised, resulting in missed deadlines and increasing stress levels. Additionally, she describes experiencing intense headaches that she rates as 7 out of 10 on the pain scale, coinciding with these episodes.
Physical examination reveals that Ms. Doe's vital signs remain elevated; her blood pressure is 142/92 mmHg and heart rate is 112 bpm, suggesting heightened sympathetic nervous system activity. Neurological examination is unremarkable, but she demonstrates a flat affect and occasional delays in responding to questions, which could indicate cognitive slowing. Initial laboratory tests, including a complete blood count and metabolic panel, are within normal limits, ruling out acute medical causes for her symptoms. However, the elevated heart rate and blood pressure, combined with her symptomatology, suggest that her anxiety may be poorly controlled despite medication.
These findings prompt the healthcare team to consider adjusting her treatment plan. There is a need to explore additional therapeutic interventions, such as cognitive-behavioral therapy or EMDR (Eye Movement Desensitization and Reprocessing), to address the underlying trauma contributing to her dissociative episodes. Furthermore, a referral to a psychiatrist for a potential adjustment of her medication regimen is deemed necessary. The team also emphasizes the importance of developing coping strategies to manage stress and improve her quality of life. The next step involves monitoring her response to these interventions closely, with particular attention to any changes in the frequency or intensity of her dissociative episodes and overall mental health status.
Section 2
Following the adjustments to Ms. Doe's treatment plan, the healthcare team observes her response to therapy and medication changes over the next few weeks. Initially, Ms. Doe reports a slight reduction in the frequency of her dissociative episodes, now occurring once or twice a week, yet the duration and intensity remain concerning. Her psychiatrist has adjusted her medication regimen, incorporating a low-dose beta-blocker to manage her elevated heart rate and blood pressure, which has shown some effectiveness; her latest vital signs reveal a blood pressure of 138/88 mmHg and a heart rate of 98 bpm. However, despite these improvements, the intense headaches persist, rated consistently at a 6 out of 10.
In parallel, Ms. Doe begins cognitive-behavioral therapy sessions focusing on trauma-informed care. Through these sessions, she identifies specific stressors related to her work environment that exacerbate her symptoms. Her therapist works with her to develop mindfulness-based techniques aimed at reducing anxiety, which Ms. Doe finds somewhat helpful in managing daily stress. Nevertheless, she continues to struggle with cognitive fog and memory gaps, notably impacting her ability to perform complex design tasks at work. This ongoing cognitive impairment prompts the healthcare team to explore further diagnostic evaluations, considering neuropsychological testing to assess her cognitive function in more detail.
Despite some progress, Ms. Doe's case presents new complications. She begins to experience symptoms of depression, including persistent sadness, a lack of motivation, and sleep disturbances, which may be secondary to her ongoing psychological distress and the impact of her condition on her occupational performance. The team decides to augment her treatment with an antidepressant, carefully selected to avoid exacerbating her dissociative symptoms. Continued interdisciplinary collaboration and regular follow-up appointments are prioritized to monitor her mental health status, gauge the effectiveness of therapeutic interventions, and adjust her care plan as necessary.
Section 3
As the healthcare team continues to monitor Ms. Doe's progress, they observed a significant change in her patient status. Over the past week, Ms. Doe reports an increase in the frequency of her dissociative episodes, now occurring three to four times a week. These episodes are more unpredictable and are accompanied by an escalation in her cognitive fog, making it challenging for her to concentrate on tasks at work and manage her daily activities. This change coincides with an increase in her depressive symptoms, suggesting a potential exacerbation of her underlying mental health condition. During her latest assessment, she presents with a flat affect, decreased eye contact, and reports feeling overwhelmed and frustrated with her lack of progress. Her sleep disturbances have worsened, with her only managing to sleep four to five hours a night, further contributing to her fatigue and cognitive impairment.
In response to the evolving clinical picture, the team decides to proceed with neuropsychological testing to gain a comprehensive understanding of Ms. Doe's cognitive deficits. The preliminary results reveal significant impairments in attention, executive function, and working memory, which align with her reported difficulties at work. These findings suggest that her cognitive issues may be intricately linked to both her dissociative disorder and her depressive symptoms. Additionally, a recent lab workup shows a mild elevation in her liver enzymes, raising concerns about the potential side effects of her current medication regimen. This prompts the team to reassess her pharmacological treatment, considering the possibility of switching to medications with a more favorable side-effect profile while ensuring continued support for her mental health needs.
The healthcare team remains committed to a multidisciplinary approach, involving her psychiatrist, therapist, and primary care provider in regular discussions to refine her treatment plan. Emphasis is placed on addressing her sleep issues, potentially integrating sleep hygiene education and considering the prescription of a non-addictive sleep aid. As Ms. Doe navigates these challenges, the team prioritizes her emotional and occupational well-being, encouraging her to explore workplace accommodations that may alleviate stress and enhance her functioning. The upcoming weeks will be crucial in monitoring her response to the adjusted interventions, with the goal of stabilizing her condition and improving her overall quality of life.
Section 4
In the following weeks, Ms. Doe's response to the adjusted interventions is carefully monitored. Despite the incorporation of sleep hygiene practices and the introduction of a non-addictive sleep aid, Ms. Doe continues to struggle with sleep disturbances, achieving only marginal improvements. She reports persistent fatigue and difficulty maintaining focus during the day. Her dissociative episodes remain frequent, occurring two to three times weekly, though they have become slightly less severe. A follow-up neuropsychological evaluation reveals marginal improvements in working memory but continuing deficits in attention and executive function, indicating that her cognitive challenges are only partially addressed by the current treatment strategy.
Meanwhile, Ms. Doe's liver enzyme levels, specifically ALT and AST, have normalized after her medication regimen was adjusted to minimize hepatotoxic risk. However, she now exhibits mild orthostatic hypotension, with blood pressure readings dropping from 120/80 mmHg when sitting to 100/70 mmHg upon standing. This new complication prompts the healthcare team to review potential side effects of her medications and ensure adequate hydration and electrolyte balance. Ms. Doe's depressive symptoms remain prominent, with her PHQ-9 score reflecting moderate depression, necessitating ongoing evaluation of her mental health support and potential augmentation or change in her psychotropic medication.
The team continues to emphasize a holistic approach, encouraging Ms. Doe to engage in regular therapy sessions focusing on cognitive-behavioral strategies to manage stress and dissociation. Workplace accommodations are gradually implemented, allowing her flexible hours and reduced workload to ease her transition back to a more manageable routine. As the multidisciplinary team reconvenes, there is a consensus on the importance of closely observing Ms. Doe's response to these interventions and making data-driven adjustments to her care plan. The next phase of her journey will focus on achieving a more sustainable balance in her mental health management, aiming for improved stability and functionality in her daily life.
Section 5
In the following weeks, Ms. Doe's condition experiences a shift, marked by the emergence of new complications. She reports an increase in the frequency of her dissociative episodes, now occurring almost daily, with an intensity that disrupts her ability to perform routine tasks. This deterioration is accompanied by new findings on her neuropsychological evaluation, which show a further decline in her attention span and executive function, suggesting that her cognitive issues are becoming more pronounced despite ongoing interventions. Additionally, she begins to exhibit symptoms of increased anxiety, characterized by restlessness and a constant sense of unease, which may be contributing to her heightened dissociative experiences.
In parallel, Ms. Doe's physical health presents additional challenges. Her orthostatic hypotension persists, with blood pressure readings now consistently dropping to 95/65 mmHg upon standing, raising concerns about her cardiovascular stability. A recent comprehensive metabolic panel indicates a mild electrolyte imbalance, specifically hyponatremia, with her sodium level at 132 mmol/L, potentially exacerbating her hypotensive episodes and contributing to her fatigue and cognitive impairments. The healthcare team suspects that her current medication regimen may be a contributing factor and decides to adjust her medications, aiming to stabilize her blood pressure and correct her electrolyte levels.
These developments prompt the multidisciplinary team to intensify their clinical reasoning efforts, considering both the psychological and physiological dimensions of Ms. Doe's condition. The team deliberates on the necessity of introducing a low-dose anxiolytic to manage her increasing anxiety, along with exploring alternative therapeutic modalities for her dissociative disorder. Additionally, they emphasize the need to reevaluate her psychotropic medications, particularly in light of her ongoing depressive symptoms and cognitive decline. The team's goal is to devise a more comprehensive, integrated treatment strategy that addresses the interconnected facets of Ms. Doe's health, moving toward improved stability and functionality.
