In this comprehensive MRCP revision video, we break down Myasthenia Gravis (MG), a core neurology topic frequently tested in MRCP Part 1, Part 2, and PACES. Understanding the autoimmune disruption at the neuromuscular junction is critical for achieving a high score. We move beyond basic definitions to explore the specific pathophysiology involving acetylcholine receptor (AChR) antibodies and muscle-specific kinase (MuSK) antibodies.

You will learn how to accurately differentiate MG from challenging differential diagnoses like Lambert-Eaton Myasthenic Syndrome (LEMS) and Botulism. We cover the classic clinical presentation, emphasizing fluctuating muscle weakness, ocular symptoms like ptosis and diplopia, and bulbar involvement affecting swallowing and speech. We also discuss the crucial association with Thymoma and thymic hyperplasia.

Furthermore, this video details the essential investigations required for a definitive diagnosis, such as single-fiber EMG, CT chest, and the ice pack test. We also provide a high-yield overview of management strategies, encompassing anticholinesterase inhibitors like Pyridostigmine, immunosuppression techniques, and emergency treatments for acute myasthenic crisis involving IVIG and plasma exchange. Stop losing marks on neurology questions and master this condition today.
