Most people have experienced muscle weakness after exercise, heavy exertion, or illness, but extreme fatigue and loss of motor control can be signs of a neurological disorder called myasthenia gravis (MG). Pronounced “my-as-theen-ee-a grav-us,” the condition affects between 14 to 40 Americans per 100,000.

Patients with MG have overactive immune systems that disrupt the body’s normal communication between nerve cells and muscle cells. 

Clinicians at the Yale Medicine Myasthenia Gravis Clinic specialize in rare neuromuscular diseases; their patients have access to high-tech diagnostics, newly approved medications, and advanced surgery.

Clinical Trials

New treatments for many conditions are tested in clinical trials, which ultimately bring lifesaving new drugs and devices to the patients who need them most. By participating in a clinical trial, you may get access to the most advanced treatments for your condition, and help determine their benefits for future patients.
