Causes, incidence, and risk factors:

The cause of this disease is unknown. It is characterized by overproduction of IgM, which causes the blood to become too thick (hyperviscosity).

This hyperviscosity interferes with blood flow through small blood vessels, which leads to many of the symptoms of the disease. The disease occurs in 5 out of 100,000 people over 50 years old.
