A neurological disorder that occurs due to the consumption of meat of a cattle which is affected with bovine spongiform encephalopathy. It is caused by an abnormal isoform of cellular glycoprotein known as a prion.

Complete answer:
A progressive neurological disorder that occurs in the cattle is called bovine spongiform encephalopathy. This is also called 'Mad cow' disease. If the diseased cattle are consumed by humans, the disease spreads to humans. In humans, this disease is called creutzfeldt-Jakob disease. This condition is extremely rare but once it is infected to a person, it cannot be cured.

Additional Information:
-Bovine spongiform encephalopathy (BSE) is a neurological disease that attacks cattle by an unusual transmissible agent called a prion. The nature of this agent is not completely understood.
-According to the data presented so far, the protein called prion present in the body turns into a harmful pathogen and attacks the central nervous system.
-It is caused by feeding cattle meat infected with BSE and scrapie sheep meat.
-When a human consumes the meat of diseased cattle the disease spreads into humans. In humans, this is called creutzfeldt-Jakob disease.
-People with creutzfeldt-Jakob disease may experience symptoms like anxiety, dementia, nervousness, psychosis, insomnia, confusion, etc.
-Cattle with bovine spongiform encephalopathy may experience symptoms like trouble walking, cattle act very nervous or very violent. Because of this symptom, it is called 'mad cow' disease.
So, the correct answer is ‘creutzfeldt-Jakob disease’

Note: -If any cattle infected with bovine spongiform encephalopathy, it usually takes four to six years to become abnormal and show symptoms.
-Once the cattle start to show symptoms. It dies within 2weeks to 6months.
