Final answer:
Creutzfeldt-Jakob disease is a fatal, degenerative brain disorder associated with the misfolding of prion proteins, characterized by rapid progression and dementia, and is the correct answer to the given question.
Explanation:
The correct answer to the question is option c) Creutzfeldt-Jakob disease. Creutzfeldt-Jakob disease is a rare, degenerative, invariably fatal brain disorder. It belongs to the family of diseases known as transmissible spongiform encephalopathies (TSEs) or prion diseases. Unlike other brain diseases mentioned, Creutzfeldt-Jakob disease progresses rapidly and is associated with sponge-like holes appearing in the brain due to the misfolding of prion proteins. This disease is characterized by rapidly progressive dementia, leading to memory loss, personality changes, and hallucinations. There is currently no cure for Creutzfeldt-Jakob disease, and it ultimately leads to severe physical and mental deterioration followed by death.
