Clinical Presentation of Myasthenia Gravis

Abstract

Despite advances in applied sciences, myasthenia gravis (MG) remains a challenging disorder to diagnose and treat. The clinical presentation results in either transient or persistent painless weakness and abnormal fatigability of any (ocular, bulbar, limbs, trunk, respiratory) or all voluntary (skeletal) muscles; however, it is usually not to the same extent. Several scoring systems of MG signs or the global state of the patient have been proposed in an attempt to provide a standard scheme for use by all investigators. Some patients may have non-muscle-related complaints due to different disorders which may be associated with MG (thymoma, thyroid disorders, other autoimmune diseases, etc.).
