  • Lack of sleep is known to be harmful to our health and well being. 
  • Now a study proves that it can also contribute to Alzheimer's disease, as the following article explains.
  • But Alzheimer's may have several origins.   
  • One of them is prions, which are pathogens that can be transmitted from medical tools such as dentists' instruments, from blood transfusions, meat contaminated with BSC, and even from person to person. 
  • This proven and alarming fact is played down by scientists and the media because of its obvious implications for the meat industry, dental care, and other medical procedures.   
  • Prions are microscopic life forms that are neither bacteria nor viruses. 
  • They can travel from grass to cow to human. Or from a contaminated item to you.
  • Certain prions can cause serious neurological damage to both animals and people, including Alzheimer's.
  • What makes prions so dangerous is that they are indestructible by any known method of sterilization.  
  • So while lifestyle and genetics may influence the incidence of Alzheimer's, there are prions lurking in our environment that are a real threat.
  • READ MORE about prions and Alzheimer's HERE
Study:  Disrupting just one night of sleep in healthy, middle-aged adults causes an increase in a brain protein associated with Alzheimer's disease, research shows.
 
Further, a week of poor sleep leads to an increase in another brain protein that has been linked to brain damage in Alzheimer's and other neurological diseases.   A good night's sleep refreshes body and mind, but a poor night's sleep can do just the opposite.

TOXIN FOUND IN SEAFOOD AND BLUE-GREEN ALGAE MAY CAUSE ALZHEIMER'S - The same algae can kill pets minutes after contact with its BMAA neurotoxin. - READ about studies showing how Alzheimers can be contagious, its link with Mad Cow Disease, and how anesthesia contributes to senility

Blue green algae growing on rocks in Cornwall ocean waters.

The following article mentions age as the top cause of Alzheimer's disease, and adds better diagnostics as a factor in its statistical increase.  But age causes SENILITY, not Alzherimer's.  Senility used to be the normal result of aging:   a little loss of memory and a bit of silliness was part of getting old.
 
Alzheimers, however, is a disease that can affect people in their forties.   
 
Also, the article on blue-green algae toxins causing Alzheimer's does not mention meat consumption as a major risk in acquiring this disease. 
 
The meat industry has succeeded in silencing the fact that cattle that may be contaminated with Mad Cow Disease can end up at slaughterhouses as long as it does not show symptoms.  It's only animals who are basically collapsing that are taking off the meat processing plant, and not at every site.
 
Due to the high costs of monitoring the health of the millions of animals arriving at meat processing plants, shortcuts must be implemented.  And so the public may end up eating contaminated beef.
 
Further on this page please see outline and web link to fascinating article on how prions, that cause brain disease, pass from the urine or feces of a sick wild animal to grass which absorbs them, to the cow that grazes on it - and then to the consumer who eats that meat.   These prions are basically indestructible.  They cannot be killed by any known sterilizing method. 
 
Also read article that exposes how Alzheimer's can be transmitted from one person to another through the use of surgical and dental instruments, and blood transfusions. 
 
And now to the latest suspect:  The BMAA toxin found in seafood and blue green algae.

Poisonous algae found in UK freshwater lakes and reservoirs could be fuelling Alzheimer's and dementia epidemic afflicting one million people
Toxin also found in seafood
such as OYSTERS
  • It is the first direct evidence that a chemical, produced by algae, might be linked to devastating brain conditions
  • Scientists have discovered the toxin in seafood and plants, through which it is feared it is entering the food chain
  • Researchers highlighted a growing body of evidence that the toxin, named BMAA, could trigger brain diseases
  • If confirmed, the chemical would be the first major environmental factor linked to increasing rates of Alzheimer’s 

  •  
    Continue reading, including articles on how the blue green algae toxin kills pets by contact, on the links between Mad Cow Disease and Alzheimers, on how Alzheimers can be contagious, how anesthesia contributes to senility, the link between aluminum and Alzheimer's, and how prions that cause neurological disease can travel from wild animal to cow through grass, and end up in the human meat eater.

    ALZHEIMERS CAN BE CONTAGIOUS - The infecting prion is resistant to sterilization - It can spread through surgery, dental work, blood transfusions, growth hormone treatments, and more.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    Scientists believe a protein known to be a hallmark of Alzheimer's can be passed in the same way as the key protein that marks CJD
    The rate of new Alzheimer's disease cases is exploding and patients are getting younger, some of them in their thirties.  

    A new study found that Alzheimer's disease may spread like infectious Creutzfeld-Jakob Disease or CJD.
     
    The prions that cause both diseases are similar, and impervious to sterilization.  This means patients could contract the disease through dental work, surgery and blood transfusions.
     
    Another cause of the epidemic of Alzheimer's and so-called dementia epidemic could be the consumption of meat contaminated with mad cow disease.  
      
    During the 1996 mad cow disease outbreak in the UK meat eaters were warned that this brain disease was passed on from animal to animal through feed (which contained discards from sick animals), and to humans who ate the meat. 

    At the height of the mad cow crisis the meat industry launched a campaign to appear to be monitoring for sick animals at the farm and at the slaughterhouse.  This was done to reassure consumers, but mad cow cases continue to appear, so the disease has not been eradicated.  
     
    The meat of sick animals can end up at the supermarket because there is no fail-proof way to detect mad cow disease in every single animal that reaches the slaughterhouse. 
     
    The meat from the California slaughter operation was used in the National School Lunch Program, which fed about 31 million school children in 2012.Only those in the last stages of the disease, when they are stumbling about, are discarded, but we can't be sure of that either.  There is photographic evidence of very sick animals being dragged to be killed and processed.  (Photo on the right.)  Read more here:
     
    Canada still bans people who have lived in the UK from giving blood because they may have the variant ​Creutzfeldt-Jakob (vCJD), sometimes called the variant or human equivalent of mad cow disease.
     
    There is no licensed test available worldwide to test for vCJD,  and the incubation period before symptoms show up is currently unknown and can last for years.
     
    A shocking study:  how prions can bind to grass and transmit disease from one animal to another:
     
    PRIONS FROM SICK DEER CAN PASS FROM DEER TO GRASS TO COW TO HUMAN - PRIONS CAUSE BRAIN DISEASESPrions that cause brain disease can pass from a wild animal urine to grass, to the cow who eats that grass, to the human who consumes beef:
     
    A few weeks this blog published an astounding study:  that prion-caused brain diseases can be passed on from a sick wild animal such as deer, to the grass on which he urinates, to the cow who eats the grass, to the human that eats the beef.
     
    The study showed that prions can bind to plants and be taken into their roots, where they may travel to the stem and leaves.
     
    Neither washing nor cooking plants will eliminate the contamination.  Just as cooking contaminated beef did not halt the spread of bovine spongiform encephalopathy (mad cow disease), another prion-caused disease

    Prions have been held responsible for a number of degenerative brain diseases, including mad cow disease, Creutzfeldt-Jakob disease, fatal familial insomnia, kuru, and an unusual form of hereditary dementia known as Gertsmann-Straeussler-Scheinker disease.

    New study warns that CJD, that causes dementia, can be passed on during surgery, dental work, and blood transfusions. 
      
    The Daily Mail:

  • Potentially explosive new study suggests disease is spread like CJD
  • Fears it could be caught from blood transfusions, ops and dental work
  • Leading brain surgeon warns sterilisation methods may not protect
  • Protein marker linked to Alzheimer's behaves in a similar way to CJD

  • In a nutshell, what’s this all about?

    PRIONS THAT CAUSE CHRONIC WASTING DISEASE can pass from wild animals to plants - from plants to cows - from cows to humans - MAD COW DISEASE is also caused by prions and is blamed for ALZHEIMER'S disease among meat eaters

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    KEY POINTS
      grazing cows
    • Chronic wasting disease is a prion disease of cervids (deer, elk, moose) and humans.
    • Animals leave prion-contaminated feces and urine on the grass.
    • Plants can take up prions from the soil and transmit them to grazing animals.
    • Cows can get contaminated with prions from the grass they eat, and then pass it on to humans.
    • Studies show that prions can bind to plants and be taken into the roots, where they may travel to the stem and leaves.
    • Neither washing nor cooking plants will eliminate the contamination.
    • Just as cooking contaminated beef did not halt the spread of bovine spongiform encephalopathy (mad cow disease), another prion-caused disease
    • Keeping cervids out of grazing or growing fields could help mitigate the contamination.
    • Prions have been held responsible for a number of degenerative brain diseases, including mad cow disease, Creutzfeldt-Jakob disease, fatal familial insomnia, kuru, and an unusual form of hereditary dementia known as Gertsmann-Straeussler-Scheinker disease.
    ~~~~~~~~~~~~~~~~~~~~

    Virology Blog - Chronic wasting disease is a prion disease of cervids (deer, elk, moose) that is potentially a threat to human health.

    A role for environmental prion contamination in transmission is supported by the finding that plants can take up prions from the soil and transmit them to animals.

    prions in plants
    A concern is that prions of chronic wasting disease could be transmitted to cows grazing in pastures contaminated by cervids.

    Consumption of infected cows would then pass the disease on to humans.

    When deer are fed prions they excrete them in the feces before developing clinical signs of infection, and prions can also be detected in deer saliva.

    In the laboratory, brain homogenates from infected deer can transmit the disease to cows.

    To determine whether prions can enter plants, wheat grass roots and leaves were exposed to brain homogenates from hamsters that had died of prion disease.

    • The map of the human body has just been radically changed.person relaxing in the forest
    • Scientists discovered new vessels that connect the brain to the immune system.
    • Could have effects on study and treatment of neurological diseases ranging from autism to Alzheimer's.
    • Scientist:  We always perceived it before as something esoteric that can't be studied. But now we can ask physical questions.
    • See also related medical articles published in before this discovery that found a connection between thoughts and the immune system performance.  They just did not know how it happened.
    • And how spending quiet time in a natural setting, such as taking a walk in the park or in a real forest, can boost your immune system.  Your positive thoughts in a beautiful setting can affect your body and your health.

    In a stunning discovery that overturns decades of textbook teaching, researchers at the University of Virginia School of Medicine have determined that the brain is directly connected to the immune system by vessels previously thought not to exist.
     
    That such vessels could have escaped detection when the lymphatic system has been so thoroughly mapped throughout the body is surprising on its own, but the true significance of the discovery lies in the effects it could have on the study and treatment of neurological diseases ranging from autism to Alzheimer's disease to multiple sclerosis.

    ANESTHESIA PRODUCES BRAIN DAMAGE IN YOUNG AND OLD - General anesthesia affects memory, weakens the immune system, and increases risk of dementia - The risk for brain damage rises with age and number of exposures - Two or more exposures in children may produce ADHD

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


    As pediatric specialists become increasingly aware that surgical anesthesia may have lasting effects on the developing brains of young children, new research suggests the threat may also apply to adult brains.
     
    Harmful: Some experts believe the use of general anaesthesia can reduce the activity of the immune system
    Researchers from Cincinnati Children's Hospital Medical Center report  that testing in laboratory mice shows anesthesia's neurotoxic effects depend on the age of brain neurons -- not the age of the animal undergoing anesthesia, as once thought.
     
    Although more research is needed to confirm the study's relevance to humans, the study suggests possible health implications for millions of children and adults who undergo surgical anesthesia annually, according to Andreas Loepke, MD, PhD, a physician and researcher in the Department of Anesthesiology.
