Study Notes
Neuromuscular Disorders
- Most neuromuscular disorders stem from issues with motor neurons, neurotransmitters, or the muscles' response to neurotransmitters.
- The neurological pathway transmits impulses from the brain to muscles, triggering contraction.
- The impulse travels down the axon, utilizing the myelin sheath for rapid transmission. Damage or lack of myelin impairs or slows impulse transmission.
Myasthenia Gravis - Pathophysiology
- Myasthenia gravis is a neuromuscular junction disorder.
- It impairs communication between the motor neurons and muscle cells.
- Antibodies target acetylcholine receptors, reducing their availability.
- This reduces the transmission of impulses, leading to muscle weakness.
Myasthenia Gravis - Risk Factors
- Predominantly affects young women (20-30 years old) and men over 50.
- Can occur at any age.
- An autoimmune disorder.
Myasthenia Gravis - Clinical Manifestations
- Diplopia (double vision).
- Ptosis (drooping of the upper eyelid).
- Facial weakness and expression.
- Dysphonia (voice impairment).
- Increased risk of choking and aspiration.
- Generalized muscle weakness.
- Weakness in extremities and intercostal muscles, leading to potential respiratory failure.
Myasthenia Gravis - Diagnosis
- Serum AChR antibody levels.
- Measures acetylcholine receptor autoantibodies.
- Electromyography (EMG).
- Records electrical activity in muscle tissue.
Myasthenia Gravis - Exacerbating Factors
- Infection
- Surgery
- Medications (e.g., aminoglycosides, quinine, magnesium sulfate).
- Pregnancy
- High environmental temperature.
- Emotional stress
- Vigorous physical activity
- Thymoma (abnormal thymus)
Myasthenia Gravis - Medical Management
- Pharmacological management:
- Anticholinesterase drugs (e.g., pyridostigmine bromide) to block the breakdown of acetylcholine.
- Corticosteroids (e.g., prednisone).
- Immunosuppressant drugs (e.g., azathioprine) to curb the immune response.
- Surgical management:
- Thymectomy (removal of the thymus).
Myasthenia Gravis - Nursing Considerations
- Medication adherence is critical.
- Schedule drug administration, especially around strenuous activities.
- Patient and family education on medication mechanisms.
- Support with extra medication supply.
- Precautions for choking and aspiration.
- Energy conservation measures.
- Monitor vision problems; consider artificial tears, glasses modifications, eye patching.
- Health teaching and provision of medical alert information.
Guillain-Barré Syndrome - Pathophysiology
- Damage or destruction of myelin sheaths in peripheral nerves.
- Reduced nerve conduction speed leads to progressive muscle weakness.
- Schwann cells, responsible for myelin production, are not affected; remyelination is possible.
Guillain-Barré Syndrome - Risk Factors
- Most common in young to middle-aged adults.
- Immune-mediated response, triggered by prior infections (e.g., Campylobacter jejuni) or vaccinations.
- Medical emergency due to rapid respiratory paralysis.
Guillain-Barré Syndrome - Clinical Manifestations
- Begins in the lower extremities and ascends.
- Flaccid weakness, difficulty walking, and progressing to paralysis.
- Symmetrical paresthesias, dysphagia, dyskinesia.
- Respiratory muscles are often affected.
Guillain-Barré Syndrome - Medical Management
- Medical emergency, requiring ICU monitoring, IV fluids, physical therapy, and potentially mechanical ventilation.
- Immunomodulating treatments like IV immunoglobulin (IVIg).
- Plasmapheresis to filter blood and remove antibodies.
Guillain-Barré Syndrome - Nursing Considerations
- Monitoring and maintaining effective respiratory function.
- Ensuring adequate nutrition, hydration, and mobility.
- Supportive care for communication difficulties.
- Addressing anxiety and potential for fatigue.
Parkinson's Disease - Pathophysiology
- Degeneration of dopamine-producing neurons in the basal ganglia.
- Depletion of dopamine leads to an imbalance between excitatory and inhibitory neurotransmitters.
- This affects voluntary movement, leading to motor symptoms.
Parkinson's Disease - Risk Factors
- Primarily affects individuals in their 50s and 60s, but younger onset is possible.
- Risk factors include genetic predisposition and environmental factors.
- Men are more commonly affected.
- Up to 80% may eventually develop dementia.
Parkinson's Disease - Clinical Manifestations
- Resting tremor (often first symptom).
- Bradykinesia (slowed movement).
- Rigidity (stiffness) of muscles.
- Postural instability — difficulty balancing.
- Shuffling gait.
Parkinson's Disease - Medical Management
- Pharmacological management:
- Carbidopa-levodopa (conversion of levodopa to dopamine in the brain); carbidopa blocks peripheral conversion, making more levodopa available in the brain.
- Dopamine agonists (e.g., pramipexole, ropinirole).
Parkinson's Disease - Nursing Considerations
- Enhancing mobility and promoting functional independence.
- Supporting self-care activities.
- Improving bowel elimination and nutrition.
- Encouraging healthy coping mechanisms and managing emotional distress.
Amyotrophic Lateral Sclerosis (ALS) - Pathophysiology
- Degeneration of both upper and lower motor neurons in the corticospinal tracts, anterior horn cells, and bulbar motor nuclei.
- Progressive, irreversible neurodegenerative disease.
- No known cure.
Amyotrophic Lateral Sclerosis (ALS) - Risk Factors
- Typically develops between ages 40-60.
- Men are more frequently affected.
Amyotrophic Lateral Sclerosis (ALS) - Clinical Manifestations
- Muscle weakness and cramps.
- Difficulty speaking/swallowing/respiration.
- Fasciculations (muscle twitching).
- Spasticity and difficulty with coordination.
Amyotrophic Lateral Sclerosis (ALS) - Medical Management
- No cure; treatment focuses on symptom management and delaying disease progression.
- Medications to manage symptoms and slow disease progression.
Amyotrophic Lateral Sclerosis (ALS) - Nursing Considerations
- Support respiratory function.
- Address issues of pain, dyspnea.
- Provide support for emotional and psychosocial needs.
- Teach adaptive strategies and assistive devices. Implement strategies to manage spasticity.
Systemic Lupus Erythematosus (SLE) - Pathophysiology
- Autoimmune disease that occurs because the immune system mistakenly attacks healthy tissue.
- The immune system produces antibodies (autoantibodies).
- Antibody-antigen complexes form and deposit in tissues, causing inflammation and damage.
Systemic Lupus Erythematosus (SLE) - Risk Factors
- Predominantly affects women of childbearing age.
- More common in African Americans than in Caucasians.
- Environmental factors, such as UV light exposure, cigarette smoking, and infections, may play a role.
