An overall decline in every area of mental and physical ability leads finally to death. CJD affects about person in a million each year globally.

CJD is due to an infectious agent referred to as a prion, which replicates in the brain and causes brain damage.
- One kind of CJD, accounting for 15 in 100 cases, has been found to run in families. Most individuals who grow this sort of CJD are over age 50. Normally, the source of the infection is unknown. In about in 20 affected folks it can traced to previous treatment with products derived from human tissue. Before the usage of man-made growth hormone to treat growing illnesses, one source of illness was human growth hormone injections.
