A myasthenic crisis is a severe worsening of muscle weakness in individuals with myasthenia gravis, an autoimmune disorder that affects communication between nerves and muscles. This condition can lead to respiratory failure, making it difficult for patients to breathe. It often requires immediate medical attention and may necessitate hospitalization. The crisis can be triggered by factors such as infections, stress, or certain medications. Treatment typically involves therapies like plasmapheresis or intravenous immunoglobulin (IVIG) to reduce the immune system's attack on the body's own receptors. Prompt recognition and intervention are crucial for recovery.
