Study Notes
Conduction Abnormalities in Epilepsy and Seizures
Etiology and Pathophysiology
- Seizures stem from abnormal electrical activity in the brain.
- Common seizure triggers include:
- Severe body temperature elevation
- Drug use
- Electrolyte imbalances
- Brain tumors
- Brain infections
- Epilepsy
- Epilepsy leads to uncontrolled electrical discharges in brain neurons, causing involuntary muscle contractions.
- Seizures exhibit varied patterns based on their origin in the brain.
- Tonic convulsions cause alternating muscle contractions and relaxations, resulting in characteristic jerking movements.
- Postictal period follows seizures with grogginess, disorientation, headaches, and amnesia about the event.
- Status epilepticus is a medical emergency characterized by continuous seizures without returning to full consciousness.
- Frequent seizures lead to neuronal exhaustion, risking permanent brain damage or death.
- Common trigger for status epilepticus is abrupt withdrawal from anticonvulsants.
Clinical Manifestations
- Seizures can be categorized into types:
- Generalized tonic-clonic (grand mal)
- Absence (petit mal)
- Psychomotor (automatisms)
- Jacksonian (focal)
- Miscellaneous (myoclonic, akinetic)
- Status epilepticus can arise from:
- Irregular antiepileptic drug intake
- Alcohol or sedative withdrawal
- Electrolyte imbalances
- Head trauma and infections
- Physiological changes during status epilepticus are:
- Phase 1: Increased cerebral metabolism, hypertension, hyperglycemia, and lactic acidosis.
- Phase 2: Decreased cerebral blood flow, systemic hypotension, and acidosis leading to cellular injury.
Assessment
- Subjective data should assess patient's understanding and awareness of seizures, including any auras.
- Auras are sensations (light, warmth) or emotions (fear) that precede seizures, occurring in about 50% of patients.
- Objective data includes seizure frequency, characteristics, and post-seizure behaviors.
- Essential assessments involve neurological, respiratory, and cardiovascular evaluations before, during, and after seizures.
- Monitor SpO2 and possible respiratory distress; prepare for suctioning and oxygenation as needed.
Diagnostic Testing
- Blood tests and toxicology screens for infections and chemical imbalances.
- Imaging tests (CT, MRI) identify lesions and seizure activity locations.
- EEG is the primary diagnostic tool for seizure evaluation.
Medical Management
- 70% of seizure disorders can be controlled with antiseizure medications.
- Therapy focuses on seizure prevention; cures are often not attainable.
- Medication choice depends on seizure type; adherence is crucial to treatment success.
- In status epilepticus, immediate treatment is critical. Initial medication typically includes IV lorazepam.
- Additional medications like levetiracetam, phenytoin, or propofol may be used if seizures persist.
- Surgical options may involve resection of the hyperactive brain area.
Nursing Interventions and Patient Teaching
- Ensure airway patency, oxygenation, and vascular access during seizures.
- Education on medication adherence, lifestyle adjustments, and the importance of follow-up care is vital.
- Caution against alcohol use when on antiseizure medications.
- Emergency treatment includes positioning, suctioning, and avoiding objects near the patient during seizures.
Prognosis
- Emotional, economic, and social impacts are significant for patients with seizure disorders.
- Stigma around epilepsy remains.
- Driving restrictions can adversely affect lifestyles.
- Outcomes vary; some patients experience stable seizure patterns while others face uncertainty due to underlying conditions.
Degenerative Diseases Overview
- Degenerative diseases involve premature aging of nerve cells due to metabolic disturbances or unknown causes.
- Key conditions:
- Multiple sclerosis (MS)
- Parkinson’s disease
- Alzheimer’s disease (AD)
- Myasthenia gravis (MG)
- Amyotrophic lateral sclerosis (ALS)
- Huntington’s disease
Multiple Sclerosis (MS)
-
Chronic, progressive disease with unknown specific cause but suspected genetic links.
-
Early signs may show an increase of gamma delta T cells in the spinal fluid.
-
Initial symptoms are vague and may take time to diagnose.
-
Symptoms include:
- Visual problems
- Urinary incontinence
- Fatigue
- Muscular weakness or coordination issues
- Sexual dysfunction
- Swallowing difficulties
-
Patients may have remissions followed by exacerbations, often triggered by fatigue or emotional stress.
-
Diagnosis relies on history, clinical signs, and MRI evidence of multiple lesions.
-
CSF in MS patients can show elevated gamma globulin levels, and CT may reveal enlarged cerebral ventricles.### Multiple Sclerosis (MS)
-
MRI scans are effective for diagnosing MS, able to detect sclerotic plaques as small as 3-4 mm in diameter.
-
No specific treatment exists for MS; however, symptoms can be managed with ACTH and corticosteroids (e.g., prednisone, dexamethasone).
-
A high-fiber, well-balanced diet is crucial, often supplemented with vitamins and high-protein foods.
-
Obesity complicates daily needs and mobility; obese patients should consult a dietitian for calorie-restricted diets.
-
Regular skin care is essential; patients should be taught to turn frequently and use pressure-relief devices like air mattresses.
-
Exercise is beneficial for patients with MS, reducing spasticity and enhancing coordination; water exercise is particularly effective.
-
Daily rest periods can help manage fatigue, especially during acute exacerbations.
-
Patients may experience unbalanced gait; stabilizing techniques include leaning toward the less affected side and emphasized foot placement while walking.
-
Patients should avoid hot environments and extended exposure to heat.
-
Emotional changes, including slow speech and unpredictable emotional outbursts, may occur.
Parkinson’s Disease
- Parkinsonism includes bradykinesia, muscle rigidity, tremors, and impaired postural reflexes.
- The disease primarily results from the loss of dopamine-producing cells in the substantia nigra, affecting movement regulation.
- More than 1 million people in the U.S. are affected; onset typically occurs after 50, peaking in the 60s.
- Diagnosis is clinical, based on history and neurological examination, requiring at least two symptoms from the classic triad: tremor, rigidity, and bradykinesia.
- Early symptoms may be subtle (e.g., mild tremors, handwriting changes) but progress to pronounced gait changes, rigidity, and possible dementia.
- "Pill rolling" tremor is characteristic, often seen at rest, and exacerbated by stress.
- Rigidity may present as a "cogwheel" effect with muscle soreness and fatigue.
- Treatment focuses on symptom management; drug treatment may lead to side effects like dyskinesia.
- Deep brain stimulation (DBS) is an advanced surgical option, improving motor complications without destroying brain tissue.
Nursing Interventions for Parkinson’s Patients
- Emphasize proper posture and ambulation techniques to prevent falls and enhance mobility.
- For patients at risk of freezing while walking, suggest techniques like stepping over lines or rocking side to side.
- Nutrition is critical; diets high in fiber assist with constipation, while bite-sized food aids swallowing.
- Patients should maintain a 90-degree angle while eating to prevent aspiration and use soft-solid or thick-liquid diets.
- Caregiver education is essential for medication adherence and to promote mobility, skin care, and proper feeding techniques.
Alzheimer’s Disease (AD)
- AD is a chronic, progressive disorder affecting brain function, leading to impairments in intellectual abilities; it is a prevalent cause of dementia, affecting genders equally.
- Neuropathological changes include the presence of cortical plaques, neurofibrillary tangles, neuronal connection loss, and subsequent cell death.### Alzheimer's Disease (AD)
- Neuronal damage primarily affects the cerebral cortex, leading to decreased brain size.
- Engagement in cognitive activities like reading and learning languages lowers the risk of AD.
- Regular physical activity and educational achievements throughout life are protective factors against AD.
- Antioxidant-rich foods such as citrus fruits, dark green vegetables, and beta-carotene-rich foods may reduce AD risk.
Clinical Manifestations of AD
- Progression typically divided into four stages, though some systems propose up to seven stages.
- Early stage: Mild memory lapses and difficulty with word usage; possible depression and lack of interest.
- Second stage: Obvious short-term memory loss, disorientation, loss of impulse control; sundowning may occur.
- Third stage: Total disorientation; motor problems like apraxia, visual agnosia, and dysgraphia; increased wandering.
- Terminal stage: Severe mental and physical deterioration; total incontinence common.
Assessment for AD
- Memory loss usually the first noticed symptom, often accompanied by agitation or restlessness.
- Important to rule out conditions like pernicious anemia, drug reactions, depression, or hormonal imbalances.
- Early warning signs include memory disruption, difficulty with familiar tasks, and withdrawal from social activities.
Diagnostic Tests for AD
- Diagnosis is largely one of exclusion; no specific diagnostic tests exist for AD.
- CT scans, EEGs, MRIs, and PET scans may rule out other conditions.
- Family history plays a significant role; definitive diagnosis can sometimes only be made post-mortem.
Medical Management of AD
- Treatment options are limited; medications can sometimes exacerbate symptoms.
- Lorazepam or haloperidol may help manage agitation.
- Memantine, approved for moderate to severe AD, does not halt neurodegeneration but slows symptom progression.
Nursing Interventions and Patient Teaching for AD
- Focus on maintaining adequate nutrition, potentially with finger foods and frequent nutrient-dense meals.
- Safety measures include securing the environment to prevent accidents related to disorientation.
- Education often targets family members, emphasizing the importance of effective communication.
Prognosis of AD
- No effective treatments currently exist to halt progression; variability in disease progression noted.
- Most patients ultimately succumb to complications like pneumonia, malnutrition, and dehydration.
- Support groups available to assist caregivers and families manage the burden of the disease.
Myasthenia Gravis (MG)
- MG is an autoimmune neuromuscular disease characterized by fluctuating muscle weakness.
- Common onset between the ages of 10 and 65, peak typically between 20-30; is now seen more in individuals over 50.
- Autoimmune process involves antibodies attacking acetylcholine receptor sites at the neuromuscular junction.
Clinical Manifestations of MG
- Symptoms include ptosis (eyelid drooping), diplopia (double vision), and general muscle weakness, particularly in extremities and diaphragm.
- Severe cases may require mechanical ventilation due to significant muscle weakness.
Assessment for MG
- Subjective data includes weakness, double vision, and swallowing difficulties.
- Objective assessment may reveal specific muscle weakness and nasal-sounding speech.
- Diagnostic testing may include observing eyelid drooping, EMG, and the IV anticholinesterase test.
Medical Management of MG
- Anticholinesterase drugs like neostigmine and pyridostigmine are standard treatments.
- Corticosteroids and immunosuppressive medications can be adjunct therapies.
- Plasmapheresis may be used for acute episodes or surgery preparation.
Nursing Interventions for MG
- Monitor for respiratory issues due to muscle weakness; patient may require hospitalization during acute episodes.
- Help plan daily activities to conserve energy for essential tasks; physical therapy may assist with mobility.
Prognosis of MG
- Respiratory failure is a significant concern; effective communication and planning are crucial for patient care.
Amyotrophic Lateral Sclerosis (ALS)
- Characterized by the loss of upper and lower motor neurons, typically leading to death within 2 to 6 years.
- Onset generally occurs between ages 40 and 70, with a higher prevalence in men.
Clinical Manifestations of ALS
- Primary symptoms include weakness, dysarthria, dysphagia, and muscle wasting.
- Respiratory failure is often the cause of death due to compromised function.
Medical Management of ALS
- No cure; riluzole may slow progression by protecting motoneurons, potentially extending life by months.
Nursing Interventions for ALS
- Encourage endurance exercises to reduce spasticity; provide emotional support and assist with communication needs.
Huntington's Disease
- An autosomal dominant genetic disorder with a 50% inheritance risk for offspring; usually diagnosed after parenthood.
- Symptoms include abnormal movements (chorea), cognitive decline, and emotional instability.
Clinical Manifestations of Huntington's Disease
- Involuntary movements progress to affect speech and swallowing, risking aspiration and malnutrition.
- Nutritional needs may reach 4000-5000 calories daily, complicating dietary management as swallowing difficulties increase.
Medical Management of Huntington's Disease
- No cure; palliative treatments include antipsychotics and antidepressants to manage symptoms.
Nursing Interventions for Huntington's Disease
- Ensure a safe environment, maintain nutritional intake, and provide genetic counseling resources for family planning.
