Creutzfeldt-Jakob’s Disease




  • Creutzfeldt-Jakob’s disease is a brain disorder that leads to dementia and eventually death. The disease is degenerative, which causes the progressive impairment of structural and functional parts of the body.


  • Creutzfeldt-Jakob’s Disease can be found worldwide.
  • It is fairly rare, with only one diagnosed case per million people every year.


  • It is believed that the cause of Creutzfeldt-Jakob’s Disease is abnormal versions of a protein called prion. Prion becomes infectious and disturbs normal biological process. 
  • Fortunately, the risk of having this disease is rare and it is not contagious by normal contact.
  • There have been some instances of infection by skin transplants, also known as iatrogenic CJD. Variant CJD is related to eating infected beef with BSE (mad cow disease). 
  • Causes can also be related to family history or by chance.


Symptoms of Creutzfeldt-Jakob’s Disease are similar to other brain disorders like Alzheimer’s disease. Others include:

  • Impaired thinking
  • Depression
  • Anxiety
  • Insomnia
  • Difficulty speaking 
  • Memory loss 
  • Changes in personality 

Symptoms will worsen over time.



  • Unfortunately, there is no cure for Creutzfeldt-Jakob’s Disease. There are drugs that can help reduce pain and other symptoms to make the patient feel more comfortable.


  • There is no way to prevent sporadic CJD and if you have a family history that puts you at a higher risk, you could talk to a genetics expert. Medical establishments follow strict policies for safety and prevention of iatrogenic CJD.
  • There is no cure for BSE or Mad Cow Disease. You can prevent BSE by avoiding, isolating and destroying any infected animal.
  • In the United States, only 3 cows have been reported to have Mad Cow Disease, whereas in Canada there have been 19 reported cases.
