seizures - Nursing Case Study

Pathophysiology

• Primary mechanism: Abnormal electrical activity in the brain occurs due to excessive neuronal firing, often caused by an imbalance between excitatory and inhibitory neurotransmitters, particularly glutamate and GABA, leading to hyperexcitability.

• Secondary mechanism: Disruption in ion channel function, especially sodium, potassium, and calcium channels, can alter neuronal membrane potential, facilitating the propagation of uncontrolled electrical signals.

• Key complication: Repeated seizures can result in neuronal injury, potentially leading to long-term neurological deficits or the development of epilepsy if not managed properly.

Section 1

During a follow-up appointment, the patient reports a significant increase in the frequency of her seizures, now experiencing episodes almost daily. Additionally, she describes a new sensation of a metallic taste in her mouth preceding seizures. This change in her condition prompts an urgent reevaluation of her medication regimen and a thorough neurological assessment. Upon examination, she exhibits mild cognitive impairment during postictal states, characterized by confusion and difficulty articulating words, which resolves within an hour. Her neurological examination shows no focal deficits, but there is noted slight tremor in her hands, raising concerns about potential side effects from her current medication or new onset of neurological changes.

Laboratory tests reveal subtherapeutic levels of levetiracetam, suggesting possible non-compliance or altered drug metabolism. Additionally, her serum sodium is found to be slightly low at 133 mEq/L, raising the possibility of hyponatremia, a known side effect of topiramate, which could potentially contribute to her increased seizure frequency. Given these findings, the medical team considers adjusting her antiepileptic drug regimen. A discussion is initiated about the potential benefits and risks of increasing the dose of levetiracetam or switching to an alternative medication. Furthermore, the team contemplates the need for dietary sodium management or the introduction of a sodium supplement to address the hyponatremia.

These developments necessitate close monitoring and reassessment. The patient is advised to maintain a seizure diary to help identify potential triggers or patterns, and she is scheduled for an EEG to further evaluate her brain's electrical activity. A referral to a neurologist specializing in epilepsy is also made to provide a more comprehensive assessment of her condition and to explore advanced treatment options, such as vagus nerve stimulation or newer antiepileptic drugs. This careful reassessment aims to better manage her epilepsy and improve her quality of life.

Section 2

As the patient continues her care under the revised treatment plan, she returns for a follow-up appointment two weeks later, presenting with notable changes in her condition. Her seizure diary reveals a slight decrease in the frequency of her seizures, now occurring three to four times a week. Despite this improvement, she reports a persistent metallic taste before seizures and has started experiencing headaches of moderate intensity following episodes. Her daughter, who accompanies her, notes that the patient appears more fatigued and slightly more irritable throughout the day.

During the physical examination, her vital signs are stable: blood pressure at 120/78 mmHg, heart rate at 76 bpm, and respiratory rate at 16 breaths per minute. However, the neurological assessment shows persistent hand tremors and now includes subtle involuntary movements in her facial muscles, raising concerns about potential extrapyramidal side effects. Additionally, her serum sodium remains low at 131 mEq/L, despite dietary adjustments, suggesting the need for further intervention to address her electrolyte imbalance.

These findings prompt a reconsideration of her medication regimen. The medical team decides to taper off topiramate, given its contribution to hyponatremia, and introduces lamotrigine as a replacement, hoping to better control her seizures while minimizing side effects. The patient's care plan is updated to include regular monitoring of electrolytes and a follow-up EEG is scheduled to assess any changes in her brain's electrical activity. The team also emphasizes the importance of adhering to her medication schedule and maintaining her seizure diary, as these will be crucial in evaluating the effectiveness of the new regimen and ensuring her long-term health and well-being.

Section 3

Two weeks after the introduction of lamotrigine and the tapering off of topiramate, the patient returns for another follow-up. During the visit, the patient reports a significant reduction in the frequency of her seizures, now experiencing episodes only once or twice a week. However, she continues to experience a metallic taste before seizures and persistent postictal headaches, albeit with slightly reduced intensity. Her daughter mentions that the patient has shown improved mood and energy levels, though she still experiences bouts of fatigue. Importantly, the involuntary facial movements have subsided, suggesting a positive response to the medication adjustment.

The latest lab results reveal that the patient's serum sodium has improved slightly to 133 mEq/L, indicating a positive trend towards resolving her hyponatremia. However, her most recent EEG shows continued abnormal electrical activity, indicating that while her seizure frequency has decreased, complete control has not yet been achieved. The medical team notes that her lamotrigine levels are within therapeutic range, and her liver function tests remain normal. Her vital signs are stable, with blood pressure at 118/76 mmHg, heart rate at 74 bpm, and respiratory rate at 15 breaths per minute.

Given the continued abnormal EEG findings and the persistent aura of metallic taste, the team considers the possibility of focal seizures that are not fully responsive to the current treatment regimen. They discuss the potential for further titration of lamotrigine or the introduction of adjunctive therapy to achieve better seizure control. The plan includes a continued emphasis on maintaining her medication schedule and seizure diary, as well as regular follow-up assessments to monitor her response to the adjusted treatment plan. The patient and her daughter are encouraged to keep track of any new symptoms or changes in her condition, which will be crucial for guiding future treatment decisions.

Section 4

Three weeks after the last follow-up, the patient returns with her daughter, reporting a change in her condition. She has begun to experience a new type of seizure characterized by brief episodes of confusion followed by short periods of unresponsiveness, occurring twice in the past week. These episodes last about one to two minutes, after which she feels disoriented for several minutes. During these events, she does not experience the metallic taste previously noted as her seizure aura. Her daughter mentions that these new episodes are distinct from her typical seizures, as they lack the usual headache and postictal fatigue.

The medical team conducts a thorough assessment, noting that her vital signs remain stable, with a blood pressure of 116/72 mmHg, heart rate of 70 bpm, and respiratory rate of 16 breaths per minute. A repeat EEG is performed, revealing increased focal slow-wave activity in the temporal region, suggestive of the new seizure focus. Her serum sodium has further improved to 135 mEq/L, continuing the positive trend toward resolving her hyponatremia. However, the emergence of these new seizure types prompts consideration of potential medication side effects or an evolving seizure pattern that may require additional intervention.

Given these new developments, the team deliberates on possible adjustments to her treatment regimen. They consider the introduction of a low-dose benzodiazepine as an adjunctive therapy to address the new seizure type while maintaining the current lamotrigine dosage. The patient and her daughter are educated about the signs of potential medication side effects and the importance of closely monitoring for any new or unusual symptoms. The team emphasizes the need for ongoing follow-up and reassessment to optimize her treatment plan and improve her overall seizure management.

Section 5

Response to Interventions

Two weeks after the adjustment to her treatment regimen, the patient returns for a follow-up appointment, accompanied by her daughter. The introduction of the low-dose benzodiazepine appears to have positively influenced her seizure control, as the frequency of her new seizure episodes has decreased. She reports only one episode of brief confusion and unresponsiveness in the past week, which resolved more quickly than previous episodes. During the initial assessment, her vital signs remain stable: blood pressure is 118/74 mmHg, heart rate is 72 bpm, and respiratory rate is 15 breaths per minute. However, the patient expresses concern about experiencing increased drowsiness and mild dizziness since the medication adjustment.

The medical team carefully evaluates these new symptoms, considering potential side effects of the benzodiazepine. Her serum sodium level remains stable at 136 mEq/L, indicating continued resolution of her hyponatremia, and a repeat EEG shows no significant changes from her previous study, with continued focal slow-wave activity in the temporal region. The team discusses the possibility of adjusting the benzodiazepine dosage to mitigate the drowsiness and dizziness while still effectively managing the new seizure type. They also explore non-pharmacological interventions, such as lifestyle modifications and stress reduction techniques, to support her overall treatment plan.

The patient and her daughter are advised on measures to reduce fall risk due to her dizziness, and they are encouraged to maintain a seizure diary to track any further changes in her condition. The team emphasizes the importance of ongoing communication and follow-up appointments to closely monitor her response to the adjusted regimen. They also discuss the potential need for further diagnostic investigations if the new symptoms persist or if there is any change in her seizure pattern, ensuring a comprehensive approach to her evolving clinical picture.
