Seizure - Nursing Case Study

Pathophysiology

• Primary mechanism: Seizures result from abnormal, excessive, and synchronous neuronal activity in the brain. This hyperexcitability is often due to an imbalance between excitatory neurotransmitters like glutamate and inhibitory neurotransmitters such as GABA, leading to uncontrolled electrical discharges.

• Secondary mechanism: Disruption in ion channel function, particularly sodium, potassium, and calcium channels, can contribute to neuronal hyperexcitability. Mutations or dysfunctions in these channels alter the electrical stability of neurons, making them more prone to firing abnormally.

• Key complication: Repeated seizures can lead to neuronal injury and alterations in brain networks, potentially resulting in cognitive impairment, increased seizure frequency, or the development of epilepsy, where the brain becomes predisposed to recurrent seizures.

Section 1

New Complications:

During a follow-up visit, the patient reports experiencing a significant increase in the frequency of her seizures. She now experiences brief episodes of confusion and memory lapses between seizures, which she did not have before. Her headaches have become more frequent and severe, occurring almost daily and often unresponsive to over-the-counter analgesics. She describes these headaches as throbbing, particularly on one side of her head, and they are occasionally accompanied by nausea and sensitivity to light. This suggests a possible development of migraine-like headaches, which can be a comorbid condition or a complication related to her epilepsy.

A recent EEG reveals increased epileptiform activity, indicating a heightened risk of seizure episodes. Her blood tests show subtherapeutic levels of Lamotrigine, suggesting possible non-compliance or altered drug metabolism. Her liver function tests are within normal limits, ruling out hepatic complications as a cause for altered drug levels. Given the increased seizure frequency and the new presentation of migraine-like symptoms, there is concern about the potential for more severe complications such as status epilepticus or the development of medication-resistant epilepsy.

Her neurologist considers adjusting her medication regimen. The proposed plan includes increasing the dose of Lamotrigine while monitoring for any side effects, particularly given her need for optimal cognitive function as a software engineer. Additionally, the neurologist considers introducing a secondary medication, such as Topiramate, which can address both seizures and migraine symptoms. The patient is advised to keep a detailed seizure and headache diary to help in monitoring triggers and efficacy of new interventions. The clinical team emphasizes the importance of medication adherence and regular follow-up appointments to prevent further complications and improve quality of life.

Section 2

New Complications

Despite the recent adjustments to her medication regimen, the patient presents to the emergency department with a new complication. Her husband reports that she experienced a prolonged seizure lasting over five minutes, which did not spontaneously resolve, indicating the onset of status epilepticus. Upon arrival, her vital signs are as follows: blood pressure 145/90 mmHg, heart rate 110 bpm, respiratory rate 22 breaths per minute, and oxygen saturation 92% on room air. She is postictal, exhibiting confusion and disorientation, and is unable to recall recent events leading up to the episode. Her pupils are equal and reactive, but she has difficulty following commands, raising concerns about possible neurological deterioration.

The clinical team initiates immediate management with intravenous benzodiazepines to abort the seizure activity and prevent further neurological compromise. Blood tests are ordered, revealing a slight elevation in white blood cell count at 12,500/mm³, suggestive of a stress response or possible infection, though her temperature remains normal at 98.6°F. Serum electrolytes are within normal limits, but her serum Lamotrigine level remains subtherapeutic at 2.0 mcg/mL, reaffirming issues with medication absorption or adherence. Given her recent history of increasing headache frequency and severity, a CT scan of the head is performed to rule out intracranial abnormalities such as hemorrhage or structural lesions.

The neurologist decides to admit the patient for close observation and further investigation. The plan includes continuous EEG monitoring to assess for ongoing subclinical seizure activity and adjustment of her antiepileptic drug regimen to achieve therapeutic levels more consistently. The team also considers a lumbar puncture to exclude central nervous system infections, given the elevated white cell count. The patient and her husband are educated on the seriousness of status epilepticus and the importance of strict adherence to medication and follow-up care to prevent future episodes. The case emphasizes the need for vigilant monitoring and timely intervention to manage complex epilepsy presentations effectively.

Section 3

As the patient is admitted for further observation, her status remains closely monitored. Over the next 24 hours, she begins to exhibit fluctuating levels of consciousness. At times, she is more alert and oriented, but these periods are interspersed with new episodes of confusion and lethargy. Her vital signs reveal a slight increase in blood pressure to 150/95 mmHg and a mild tachycardia at 115 bpm, but her oxygen saturation improves to 95% with supplemental oxygen. Despite these interventions, the patient's neurological status remains concerning, and she develops a low-grade fever of 100.4°F, prompting the team to reconsider the possibility of an infectious etiology contributing to her status epilepticus.

The results from the continuous EEG monitoring indicate intermittent subclinical seizure activity, confirming the need for further adjustment of her antiepileptic therapy. The serial blood tests show a further increase in the white blood cell count to 13,800/mm³, raising the suspicion of an underlying infection. In light of these findings, the team decides to proceed with a lumbar puncture to rule out meningitis or encephalitis. The cerebrospinal fluid analysis reveals an elevated protein level and mild pleocytosis, consistent with a viral infection. This new complication suggests that the patient's seizure disorder may be exacerbated by a central nervous system infection, necessitating a comprehensive antiviral treatment plan alongside her revised antiepileptic regimen.

The evolving clinical picture requires the healthcare team to engage in critical clinical reasoning to address the interplay between the patient's seizure disorder and the newly identified infection. The plan now includes broad-spectrum antiviral medications, continued EEG monitoring, and careful titration of her antiepileptic drugs to stabilize her condition. The patient's husband is kept informed about the new findings and the adjusted treatment approach, emphasizing the importance of vigilance for any further changes in her neurological status. This phase of the case highlights the complexity of managing seizures in the context of concurrent infections, underscoring the need for a multidisciplinary approach to optimize patient outcomes.

Section 4

As the patient continues under the care of the multidisciplinary team, the response to the new interventions is closely monitored. Over the next 48 hours, her condition shows mixed progress. The broad-spectrum antiviral treatment appears to slow the progression of the suspected viral infection. Her fever gradually subsides to 99.1°F, suggesting a positive initial response to the antiviral therapy. However, her neurological status remains variable. Although there are periods of improved alertness, they are still punctuated by episodes of confusion and lethargy, indicating the ongoing challenge of managing her central nervous system complications.

During this period, additional diagnostic results reveal further insights. A repeat EEG shows a decrease in subclinical seizure activity, suggesting that the adjustments in her antiepileptic regimen are beginning to take effect. However, her blood pressure remains elevated at 148/92 mmHg, and her heart rate is persistently high at 112 bpm, indicating autonomic instability potentially exacerbated by the infection and seizure activity. A comprehensive metabolic panel shows electrolyte imbalances, including a mild hyponatremia with a sodium level of 133 mmol/L, necessitating careful correction to prevent worsening of her neurological symptoms.

The healthcare team faces the complex task of balancing her antiepileptic adjustments with the need to manage her infection and stabilize her hemodynamic status. Her husband is updated on the situation, and they discuss the importance of maintaining a stable environment to minimize seizure triggers. The team considers the potential need for further imaging to assess for any underlying structural changes in the brain, which could be contributing to her persistent symptoms. This phase of the case exemplifies the intricate interplay between multiple medical issues and the necessity of ongoing clinical reasoning to adapt the care plan accordingly.

Section 5

As the medical team continues to carefully monitor the patient, a new complication arises that demands immediate attention. Approximately 72 hours into her treatment, the patient experiences a sudden increase in seizure frequency, with two generalized tonic-clonic seizures occurring within a span of six hours. This escalation in her condition prompts the team to reevaluate her current antiepileptic regimen. Despite previous adjustments, the breakthrough seizures suggest that her current medication levels may be subtherapeutic or that there is an underlying issue exacerbating her seizure activity.

Further investigation reveals that her serum antiepileptic drug levels are at the lower end of the therapeutic range, likely contributing to the inadequate seizure control. Additionally, her repeat metabolic panel indicates a further decrease in sodium levels, now at 131 mmol/L, which could be a contributing factor to her increased seizure activity. This hyponatremia, coupled with her persistent autonomic instability, underscores the complexity of her case. The team is tasked with the critical decision of how to adjust her medication while carefully correcting her electrolyte imbalance to avoid rapid shifts that could provoke further neurological complications.

In response to these developments, the healthcare providers decide to cautiously increase her antiepileptic dosage and initiate a slow sodium correction protocol. They also implement continuous cardiac monitoring to closely observe her hemodynamic status, given the risk of autonomic dysfunction. In consultation with the neurology team, they explore the possibility of adding a second antiepileptic drug to provide better seizure control. Throughout this process, the team communicates with the patient's husband, ensuring he understands the adjustments being made and the importance of ongoing vigilance for any changes in her condition. This stage of the patient's journey highlights the necessity of dynamic clinical reasoning and the constant re-evaluation of her treatment strategy to effectively manage her evolving medical challenges.
