Which of the following can be a symptom of Creutzfeldt-Jakob disease?

Creutzfeldt-Jakob disease (CJD) is characterized by a rapid progression of dementia, which results from the degeneration of brain tissue due to prion infection. This neurodegenerative condition leads to a swift decline in cognitive function, and individuals often exhibit symptoms such as confusion, memory loss, personality changes, and a marked and rapid deterioration of mental capacity. The unique nature of CJD involves this rapid clinical progression compared to other forms of dementia, which may develop more gradually.

While severe headaches, skin rashes, and stomach cramps can be associated with various other medical conditions, they are not characteristic symptoms of CJD. The disease's hallmark is indeed the quick advancement of dementia and related neurological impairments. Understanding these symptoms is vital for recognizing and diagnosing prion diseases, as they differ significantly from other neurological disorders.
