CJD is a rare brain disease that affects approximately one person per million people worldwide per year. CJD occurs when a normal brain protein changes into an abnormal form called a “prion” and accumulates in brain cells. CJD can occur sporadically, from genetic mutation, or it can be acquired. It is not easily transmitted from person to person.

CJD patients have a range of neurological symptoms that get worse as the disease progresses. Symptoms may include: failing memory, difficulty with walking, blindness, and problems with common activities of daily living.

There is no specific treatment or therapy that has been shown to stop the progression of the disease. There is currently no easy diagnosis for CJD. Physicians often make a presumptive diagnosis of CJD on the basis of the typical signs and symptoms and progression of the disease.
