Creutzfeldt Jakob disease(CJD) is a fatal degenerative brain disease called “mad cow disease” by the mainstream media. It has many similarities with Alzheimer’s disease, because it began with the rapid development of memory problems; behavior variation including paranoia, obsessive compulsive symptoms and psychosis; insufficient balance, falls and visual problems. Along this road, the symptoms will develop into dementia and restlessness. Compared with Alzheimer’s disease, it progressed much faster. They soon fell into coma. About 70% of patients with Creutzfeldt Jakob disease died within one year after diagnosis. In 1920, the disease was named after German doctors Hans Gerhardt Cruzfeld and Alphonse Jacob. Klutzfeldt Jakob disease is explained by the infectious non natural protein called protein virus. The cause of most CJD cases is unknown, and only about 10% of mothers and fathers inherit it by autosomal dominant inheritance. CJD has three forms: sporadic, familial and acquired. If exposed to the brain and spinal cord of the infected person, it may even lead to the distribution of the disease. There is absolutely no evidence that Creutzfeldt Jakob disease spreads among people through regular contact with infected people. CJD affects about one person per million every year, and the onset age is generally about 60 years old.

The variety of Creutzfeldt Jakob disease is the human form of mad cow disease, which affects cattle. It is a widely used term for many problems reported by popular media. It is believed to be the result of eating beef products contaminated by nervous system tissues such as bovine brain and spinal cord contaminated by mad cow disease. In the 1980s and 1990s, 178 people died in Britain after eating infected beef. British beef is banned from foreign trade all over the world, and some restrictions were not implemented until 2019. This incident caused a strong reaction of the public to the disaster and the fear of the mass media. In the United States, it is necessary to remove all brain and spinal cord components from high-risk cows with any signs of neurological problems. In this way, infected cattle products will not enter the food chain, thus protecting the health of the public. Due to the comprehensive measures taken, this is likely to become a worrying problem today.

CJD has no specific strategy. Drugs can help relieve pain and not exercise often. In addition to antidepressants, sedatives can also be used to treat psychological symptoms such as anxiety and depression. A variety of treatments that can delay the progress of the disease are being explored. Among them, the most promising may be monoclonal antibodies that have been proved to almost stop the progress of the disease in several individuals.
