There is a disease that strikes just 300 Americans each year. Yet, it is a nightmare that some have described as a lightening quick version of Alzheimer's & Parkinson's diseases combined. For families losing loved ones, research holds the only hope.
Here's Dennis Douda for Medical Edge.
There is kind of a cause. It can be passed down by sperm which is a small chance, or it could be in any meat you eat, along with certain surgeries. That's why I'm a vegetarian now other than the fact that cows have feelings along with other animals. This disease can kill you slowly and take years or kill you in a week. You never know when the person will die. You can be 15 and get it or 60 and get it. I havent had it in my family, but I do know alot about it. This video needs to be revised. Also someone in the comments said it can happen with deer and elk but that's not what cjd is. That would be chronic wasting disease and is a totally different factor.
Prion diseases like CJD or Kuru in humans and BSE in animals are in-built evolutionary fail safes. Cannibalism harms the species because it defies the concept of survival. Ask yourself, how can a species thrive if it eats itself? By feeding herbivore cows the brains of other cows in modern agricultural practices, we effectively bypassed evolution and thus created a new anomaly. This anomaly takes the form of the most fatal diseases known to mankind. If we don't learn these lessons we are doomed to create the deadliest plague in human history as we unknowingly consume this tainted meat.
Well said. I gave a lengthy presentation on CJD and BSE during my doctoral program in clinical psych. I was terrified by what I learned, and then I terrified my cohort. I remember reading that, not only are these diseases virtually indestructible, they can spontaneously appear without exposure. While very rare, it is possible for the mutation of this misshaped protein to sporadically appear and destroy lives . These diseases can remain dormant for years, so it would be next to impossible to pinpoint specific details of transmission.
I find these diseases both frightening and fascinating at the same time, especially from an evolutionary/psychological perspective. For my research project, I went as far back as Kuru in Papau New Guinea, and I believe there was cannibalism (as a cultural tradition?) and possibly a river where dead and diseased bodies were tossed in, which was also a source of water for this village. I digress.
My main purpose for commenting was to touch on your statement about prions as evolutionary failsafes. While feeding normal cows with ground up, infected brain matter from cows with BSE, that will certainly kill them. BUT, even in the hypothetical event that this horrific practice no longer occurred, the disease could, and likely would, live on. Sporadic mutation. It reminds me of the first Jurassic Park when the eccentric scientist (who talks about chaos theory) finds it hysterical that the lab attempted to place constraints on the Raptors (and inability to breed) by engineering females. The lab used a strain of frog DNA that, unbeknownst to them, had the ability to change sex when in an environment that inhibited its survival. I think it was Jeff Goldblum who said something like, no matter how many constraints we try and place on life to try and contain it, it will find a way. Humans must live and humans must die. To what extent are we, as humans, disrupting the natural progression of life and death? Very difficult questions to think about.
Two other prion diseases of interest are chronic wasting disease and fatal familial insomnia.
cjd and mad cows disease is a fraud.
they painted organophosphates onto the cows (and other animals).
research concentrated organophosphate painted onto cows.
research what organophosphates do to people (and cows)
There are many different versions of Prion illnesses some can last 10 years or more our family has a hereditary version where we all are increasingly ill over a 10 year period we lost my uncle my grandma and now I am doing very poorly now im guessing the final stage could happen at any time.
thedans857 now 1 in 2000 expected and approximately since states don't gave to report and often autopsies aren't done and in autopsy it's contagious which is probably why they don't want to do them and why then no reposting
O.05: Transmission of prions to primates after extended silent incubation periods: Implications for BSE and scrapie risk assessment in human populations

Prion diseases (PD) are the unique neurodegenerative proteinopathies reputed to be transmissible under field conditions since decades. The transmission of Bovine Spongiform Encephalopathy (BSE) to humans evidenced that an animal PD might be zoonotic under appropriate conditions. Contrarily, in the absence of obvious (epidemiological or experimental) elements supporting a transmission or genetic predispositions, PD, like the other proteinopathies, are reputed to occur spontaneously (atpical animal prion strains, sporadic CJD summing 80% of human prion cases). Non-human primate models provided the first evidences supporting the transmissibiity of human prion strains and the zoonotic potential of BSE. Among them, cynomolgus macaques brought major information for BSE risk assessment for human health (Chen, 2014), according to their phylogenetic proximity to humans and extended lifetime. We used this model to assess the zoonotic potential of other animal PD from bovine, ovine and cervid origins even after very long silent incubation periods. We recently observed the direct transmission of a natural classical scrapie isolate to macaque after a 10-year silent incubation period, with features similar to some reported for human cases of sporadic CJD, albeit requiring fourfold longe incubation than BSE. Scrapie, as recently evoked in humanized mice (Cassard, 2014), is the third potentially zoonotic PD (with BSE and L-type BSE), ***thus questioning the origin of human sporadic cases. We will present an updated panorama of our different transmission studies and discuss the implications of such extended incubation periods on risk assessment of animal PD for human health.

Zoonotic Potential of CWD Prions

Chronic wasting disease (CWD) is a widespread and expanding prion disease in free-ranging and captive cervid species in North America. The zoonotic potential of CWD prions is a serious public health concern. Current literature generated with in vitro methods and in vivo animal models (transgenic mice, macaques and squirrel monkeys) reports conflicting results. The susceptibility of human CNS and peripheral organs to CWD prions remains largely unresolved. In our earlier bioassay experiments using several humanized transgenic mouse lines, we detected protease-resistant PrPSc in the spleen of two out of 140 mice that were intracerebrally inoculated with natural CWD isolates, but PrPSc was not detected in the brain of the same mice. Secondary passages with such PrPSc-positive CWD-inoculated humanized mouse spleen tissues led to efficient prion transmission with clear clinical and pathological signs in both humanized and cervidized transgenic mice. Furthermore, a recent bioassay with natural CWD isolates in a new humanized transgenic mouse line led to clinical prion infection in 2 out of 20 mice. These results indicate that the CWD prion has the potential to infect human CNS and peripheral lymphoid tissues and that there might be asymptomatic human carriers of CWD infection.

I strenuously once again urge the FDA and its industry constituents, to make it MANDATORY that all ruminant feed be banned to all ruminants, and this should include all cervids as soon as possible for the following reasons...
In the USA, under the Food and Drug Administrations BSE Feed Regulation (21 CFR 589.2000) most material (exceptions include milk, tallow, and gelatin) from deer and elk is prohibited for use in feed for ruminant animals. With regards to feed for non-ruminant animals, under FDA law, CWD positive deer may not be used for any animal feed or feed ingredients. For elk and deer considered at high risk for CWD, the FDA recommends that these animals do not enter the animal feed system.
***However, this recommendation is guidance and not a requirement by law.

Insights into CWD and BSE species barriers using real-time conversion
It is NOT one in a million, and is not reportable to the CDC. Many in my small state are victims, and are all ages. I lost a sister in less than 6 months. It initially was diagnosed as a sinus infection, which is common. It's food borne, meat borne, carried by deer and moose. All victims have food preparation or hunting in common.
I have another CJD death to report. My Aunt died July 26, 2013 in St. Louis, MO. She was 65 and also lived in Houston, TX a great deal of her life. It was a quick, unexpected death and apparently very rare here in the US. Since she became ill, I have boycotted anything bovine related and have switched to a plant based diet. I have never felt more healthy in my life.
Take between 30 and 60 minutes (and up to 4 hours) before sex; works for about 4 hoursRecommended dose for most men is 50mgs; after that, dosage may go to as high as 100mg, or as low as 25mg, which may be prescribed for men over 65.Quickly absorbed by the body, less effective after a high-fat meal, and best taken on an empty stomach.

The daily pill stays effective in between doses, but may take 4 to 5 days before it begins working. The “weekender” version of Cialis can start working in as little as 30 minutes for men who take the highest dose of the drug (20mgs); it stays effective in the body for up for 36 hours.Daily pill comes in both a 2.5mg and 5mg tablet; most men start with the lower dose. The use-as-needed, “weekender” pill comes in 5, 10 and 20mg strengths; recommended starting dose is 10mg,Can be taken with or without food. Avoid heavy drinking (5 glasses of wine or 5 shots of whiskey); when combined with Cialis, it can lead to headaches, dizziness, an increase in heart rate, and a drop in blood pressure.
