What diseases are caused by prions?

are infectious proteins responsible for a number of diseases in different animals, including humans. The word prion is portmanteau "protein" and "infectious". They were first theorized in the 60s and their existence and nature was confirmed at the beginning of the 80s.

There are many different types of diseases caused by prions. All prion diseases affect the recipient's brain and none are treatable, which eventually leads to death. Recent development may eventually lead to a vaccine in the future. A disease known as Scrakie is a prion disease that attacks sheep and goats. The priorities are responsible for Norwegian encephalopathy in minks. Chronic waste affects certain types of deer and elk and cat encephalopathy and cat spongiform encephalopathy of cats.popel; more often referred to as crazy cows. The crazy cow disease was not known until the second part of the 20th century, and its discovery came to most people something as a shock. Although it was not as serious in cattle as other livestock diseases - especially hooves and illnessTown of the mouth - it gained a huge amount of attention when it was found that it could apparently jump species to infect people.

Most of these diseases caused by prions have as their vector of transmission of ingestion of contaminated meat - especially brains - the same species. Since modern practices often use ground bones and waste meat as a supplement for protein for livestock, many cattle enjoyed other cattle, including brain tissue. It seems that the decrease in certain temperature instructions for sterilization in the UK allowed prions to move freely abrasion took place on a small scale.

There are four primary diseases caused by prions. The first, Creutzfield-Jakob's disease, has a variant known as VCJD, which seems to be transmitted by the ingestion of contaminated beef. VCJD is the most common of prion diseases in humans, but is still relatively rare - infects only ASEven one of every millions of people. Like all prion diseases, VCJD attacks the brain. Symptoms include dementia that progresses very quickly, followed by hallucinations, serious memory loss, seizures, motor function loss and eventually death. Time from start to final death at VCJD is relatively short - rarely for more than a few months, sometimes less than a few weeks.

Gerstmann-Straussler-Scheinker Syndrome (GSS) is another disease in people caused by prions, albeit much less common than VCJD. It is assumed that GSS affects only about one of all one hundred million people, which is incredibly rare. The cause of GSS is considered an agentic change and the exact vector is unknown. GSS victims experience dementia and loss of coordination, which eventually leads to death. The average life expectancy for GSS victims is better than for those with VCJD, but rarely for more than a few years.

Fatal familial insomnia is another disease in people that have recently been discovered as caused by prions. The disease is known and the stemMental since the end of the 1970s, but only in the 1990s was the responsible Prion discovered. FFI is usually characterized by chronic insomnia, which in turn leads to many psychological dysfunctions. Later, the deception and hallucinations begin to disappear completely. Finally, after about a year from the beginning, the patient will die.

is the last and first discovered from common human diseases known to be caused by prions. Kuru is also sometimes known as laughter, as a result of misleading laughter that often accompanies him. It was first discovered in parts of New Guinea at the beginning of the 20th century, especially in the South For area. This area had a high prevalence of ritual cannibalism, and it is now known that the consumption of human brain tissue was responsible for the transmission of the disease.
