Myasthenia Gravis Crisis and Maintenance
Acetylcholine receptor antibodies, thymectomy indications, and crisis management.
Myasthenic Crisis Management
Defined as respiratory failure requiring intubation or noninvasive ventilation. Triggers often include infection, surgery, or medication changes.
- Rapid treatments: IVIG (2 g/kg over 2-5 days) or Plasmapheresis (5-6 exchanges over 10-14 days). Both are similarly efficacious.
- Avoid high-dose initiation of corticosteroids during acute crisis as it may transiently worsen weakness.

Common Clinical Mistakes
- Premature anchoring on common diagnoses without evaluating red flags.
- Over-reliance on neuroimaging while neglecting detailed physical exams.
- Suboptimal dosing of first-line agents before declaring treatment failure.
Frequently Asked Questions
- When is immediate specialist referral required?
- Urgent referral is indicated for sudden onset of severe symptoms, rapidly progressive deficits, or when standard therapies fail.
- What are the primary outcome measures in recent clinical trials?
- Most contemporary trials focus on slowing disease progression (e.g., EDSS in MS, UPDRS in Parkinson's) and reducing relapse/event rates.
- How does this condition impact patient life expectancy?
- While highly variable, modern disease-modifying therapies have significantly improved long-term survival rates across neurodegenerative and neuroimmunological disorders.
