Understanding Myasthenia Gravis Pathophysiology and Diagnostic Testing

This chapter explores the pathophysiology of myasthenia gravis, detailing how autoimmune antibodies disrupt signal transmission at the neuromuscular junction, leading to muscle weakness. It discusses the importance of testing methods, including antibody testing, nerve stimulation tests, and single fiber EMG tests, in diagnosing myasthenia gravis. The chapter emphasizes the significance of acetylcholine receptor antibody panel testing and explains the technical aspects of diagnostic procedures like single fiber EMG and nerve stimulation testing.
