Answer :
The disease is an extremely rare brain disorder that causes dementia.
Creutzfeldt-Jakob disease (CJD), also known as subacute spongiform encephalopathy or prion disease neurocognitive disorder, is a fatal degenerative brain disorder. Memory problems, behavioral changes, poor coordination, and visual disturbances are among the early symptoms. Dementia, involuntary movements, blindness, weakness, and coma are later symptoms. Approximately 70% of people die within a year of being diagnosed. Walther Spielmeyer coined the term Creutzfeldt-Jakob disease in 1922, after the German neurologists Hans Gerhard Creutzfeldt and Alfons Maria Jakob.
Creutzfeldt-Jakob disease (CJD) is caused by a prion, which is an abnormal infectious protein in the brain. Proteins are amino acid-based molecules that help our bodies' cells function. They begin as a string of amino acids that fold into a three-dimensional shape. They may experience discomfort, and some of the disease's symptoms, such as myoclonus, can be distressing to caregivers. Neurologists believe that the disease itself causes no pain.
