Creutzfeldt-Jakob disease (CJD) is a rare and fatal condition that affects the brain. CJD appears to be caused by an abnormal infectious protein called a prion. These prions accumulate at high levels in the brain and cause irreversible damage to nerve cells, resulting in loss of intellect and memory, change in personality, loss of balance and co-ordination, vision problems and blindness as well as abnormal jerking movements.
