A diagnosis of cold agglutinin disease (CAD) can be challenging for patients and their families. As a rare disease, it can be difficult to find information about CAD or its treatments.
To help, below are answers to some frequently asked questions about CAD.
What is CAD?
CAD is a rare autoimmune disease in which immune cells mistakenly attack the red blood cells that carry oxygen to tissues. This results in a type of anemia (loss of red blood cells) that is made worse by cold exposure.
How do I know if I have CAD?
The most common symptoms of CAD are fatigue and weakness due to anemia. Many patients also have a condition called Raynaud’s phenomenon, marked by the pinching in cold weather of small vessels that carry blood to the hands and feet.
How prevalent is CAD?
CAD is rare, diagnosed in about 1 in every 80,000 people. It mostly affects those over age 50 or 60.
Is CAD contagious?
CAD is not contagious, and cannot be transmitted from person to person.
Can CAD be inherited?
Genetics may play a role in how CAD develops, but at this time, there is no known genetic cause.
