The Neuromuscular Clinic at the Perron Institute, also known as the Inflammatory Myopathies Clinic provides comprehensive management and treatment for people with inflammatory myopathy.
Myopathy is a term used to describe any form of muscle disease and the inflammatory myopathies are a group of diseases that involve chronic muscle inflammation (myositis) accompanied by muscle weakness.
There are three main types of chronic or persistent inflammatory myopathy; polymyositis, dermatomyositis, and inclusion body myositis.
Muscle inflammation may be caused by an allergic reaction, exposure to a toxic substance or medicine, another disease such as cancer or rheumatic conditions, or a virus or other infectious agent. The chronic inflammatory myopathies are idiopathic, meaning they have no known cause. They are thought to be autoimmune disorders, in which the body’s white blood cells (that normally fight disease) attack blood vessels, normal muscle fibers, and connective tissue in organs, bones, and joints.
