Myasthenia gravis (MG) is a chronic neurologic disease and the most common disease of neuromuscular transmission. Although neurologists should be involved in the care of these patients, diagnosis often begins at the primary-care level.

To prevent delay in diagnosis, primary-care providers (PCPs) must understand variations in the presentation of MG as well as basic diagnostic tools. Knowledge of treatment of the disorder and an understanding of some of the challenges people with MG face allows the PCP to work in synergy with the neurologist to provide a more comprehensive health plan.
