Final answer:
Creutzfeldt-Jakob disease (CJD) is a fatal neurodegenerative disorder associated with Mad Cow Disease and is characterized by memory impairment, coordination problems, and behavioral changes. It is caused by abnormal prion proteins and leads to the degeneration of neural tissue.
Step-by-step explanation:
The rapidly fatal disorder that impairs memory, coordination, and causes behavior changes, and is believed to be caused by Mad Cow Disease, is Creutzfeldt-Jakob disease (CJD). CJD is characterized by the degeneration of neural tissue, leading to sponge-like lesions in the brain due to abnormal formations of prion protein. This neurodegenerative disease is untreatable and ultimately fatal, with symptoms including memory loss and motor control issues, which culminate in dementia. It is linked to the consumption of diseased meat and is comparable to Bovine Spongiform Encephalopathy (BSE) in cattle, more commonly known as Mad Cow Disease. Such prion diseases lead to the misfolding of proteins, impacting the structure and function of the brain.
