Creutzfeldt-Jakob Disease Related Dementia

Creutzfeldt-Jakob disease (CJD) is the most common of a group of rare dementia types called spongiform encephalopathy.

Creutzfeldt-Jakob disease and other related diseases are the result of abnormal proteins in the brain called prions. Once present in the brain, prions “infect” healthy proteins, creating new prions. These prions affect the brain’s normal functions and lead to personality changes and problems with memory, movement, and vision. This process occurs very quickly and most individuals who develop Creutzfeldt-Jakob disease die within a year.

Creutzfeldt-Jakob disease is a transmissable disease; however, a person who has daily contact with someone with the disease is at very low risk for contracting it. The highest risk for infection comes from exposure to tissue and fluids from the brain and spine. Less than one percent of CJD cases are caused by person-to-person transmission — usually the cause of CJD is unknown.
