Creutzfeldt-Jakob disease (CJD) is a rare disease that causes fast deterioration of an affected person’s brain. As this condition worsens and damages your brain, it causes dementia-like symptoms.
With CJD, faulty proteins, known as prions, build up in your brain cells, damaging and destroying those cells. The condition is very severe, and its effects develop and worsen quickly. It’s ultimately fatal, and unfortunately, there’s no way to cure, treat or even slow down the progress of this disease.
