What is myasthenia gravis?
Myasthenia gravis (MG) is a rare neuromuscular condition, characterized by weakness and rapid fatigue under voluntary control, caused by deterioration of ordinary communication between nerves and muscles.1 The usual cause of MG is an acquired immunological abnormality, but some cases result from genetic abnormalities at the neuromuscular junction.2

What are the symptoms of myasthenia gravis?
Symptoms may include: droopy eyelids and/ or double vision, difficulty speaking, difficulty breathing, problems chewing and swallowing or trouble performing everyday tasks and generalized muscle weakness.4
How is it diagnosed?
A diagnosis of MG is confirmed via several methods, including the following:
Acetylcholine receptor (AChR) antibody testing - Blood test to detect abnormal antibodies.4
Anti-MuSK antibody testing - Blood test for MG patients who have tested negative for the acetylcholine antibody (AChR).4
Ice Pack tests - Ice Pack tests are examinations performed by specialists to evaluate strength and recovery responses that could be consistent with an MG diagnosis.4
Edrophonium test - Edrophonium is a drug that prevents the breakdown of acetylcholine, allowing the clinician to understand your muscle response and whether the results are consistent with an MG diagnosis.4
Electromyography (EMG) - Repetitive nerve stimulations (RNS) applying electrical shocks are often used to gauge muscle response and action potential and whether results are consistent with an MG diagnosis.4
Single-fiber electromyography (SFEMG) - Detects neuromuscular transmission defects by recording action potentials from individual muscle fibers using a small needle electrode.4
A clinician skilled in recognizing and distinguishing MG from other conditions is important in determining a proper diagnosis.4
