There are many conditions that may cause madness. The expression "mad as a hatter" however, has a most interesting history, so I will recount it here ...

Mercury (Hg, number 80 on the periodic table of elements) was not found to be dangerous for many years after its discovery and was used in a wide variety of products such as thermometers and lamps. Many miners wore headlamps that contained mercury, and sometimes when these lamps broke, the mercury would seep into their scalp and cause insanity. Therefore, mercury is a very dangerous substance which may cause madness.

However, "madness" is not a medical term or diagnosis. There are many different types of mental illness.

Prions, and the symptoms that occur when a sheep and cow get this disease: it affects their normal brain function, and they behave abnormally until they suddenly up and die.

At the cellular level, mad cow disease (BSE or bovine spongiform encephalopathy) is caused by a mis-folded protein that causes other copies of the same protein to mis-fold as well. These mis-folded proteins (called prions) do not function and cannot be broken down by the cell, so they accumulate like so much cellular junk in the cytoplasm until the cell dies from inability to function. The clinical signs at the whole animal level are caused by the deaths of nerve cells.

In contrast, at the cellular level cancer is caused by one or more genetic mutations that cause the cell to divide rapidly and disregard the normal intercellular signals to stop dividing. While there are sometimes significant abnormalities in protein production and function, these are a side effect of the cancer rather than the underlying cause.

No.

Iatrogenic CJD occurs when a person is infected during a medical procedure, such as organ donation, blood transfusion, or brain surgery.

Yes.

Bovine spongiform encephalopathy (BSE, the scientific name for mad cow disease) is caused by a prion, a normal protein that is mis-folded and cannot be broken down by the body.

Currently the prohibition on giving blood if you were present in the UK during the BSE outbreak is permanent.

Because of carelessness. If animals that had BSE did not get into the food chain for either humans and other ruminants in the first place, and instead were burned and buried, then none of this would've happened. The USA liked to blame Canada for all the problems of "spreading the disease" when the cow that had BSE in 2003 was originally from the States in the first place. And the next thing you know, the USA is claiming that they are "BSE free." Which is a load of you-know-what.

There are no known cures for MCD in its human form, which is otherwise known as variant Cruetzfeldt-Jakob Disease (vCJD). Nor are there any cures for MCD in the bovine version, which is otherwise known as Bovine Spongiform Encephalopathy (BSE). As a matter of fact, no form of this disease in any animal that is likely to be affected (sheep, bison, buffalo, elk, deer, etc.) has any sort of cure whatsoever. This disease in sheep and goats is called Scrapie. In cervids, it is called Chronic Wasting Disease. BSE, Scrapie, and CWD are all collectively known as Transmissble Spongiform Encephalopathy (TSE). Thus, TSE is not curable.

"There is currently no proven treatment for the underlying process" which causes variant CJD according to the Edinburgh CJD unit in Scotland, in the United Kingdom (July 2006). This is also true for the bovine variant, sheep variant or cervid variant of this disease. The only possible treatment available (if you can call it that) is humane euthanasia of the affected animal.

The central nervous system.

Mad cow disease is the name of a syndrome given to an unusual spike in the number of cattle showing neurologic signs in the United Kingdoms in the 1980s. The disease was given the formal name of bovine spongiform encephalopathy based on the microscopic signs of the disease in the brain and is often called BSE for short. BSE is caused by a prion, a mis-folded protein in the brains of cattle, so it is not caused by a protist.

BSE, bovine spongiform encephalopathy, is a prion disease in bovine mammals, notably cows. Because the causative agent is not living and is in fact related to 79 proteins naturally occurring in bovines, the immune system does not recognize the protein as a pathogenic agent and thus is unable to mount a resistance against it. Therefore, the immune system of any animal infected with a prion disease is unable to fight against it.

mad cow disease is when cows get it. when the disease is passed on 2 humans, it's called the Creutzfeldt-Jakob Disease. so technically its the same thing, just in different species

CJD is a chronic progressive neurologic disease that is 100% fatal.

Both diseases are caused by a prion (infectious misfolded protein) that affect the Central Nervous System (the brain and spinal cord). The incubation period of this prion is drawn out over a period of 10 years, and the end result of this disease leads to dysfunction of the CNS causing irregular mobility, attitude changes and eventually death. BSE (the proper term for "Mad Cow Disease") and CWD are neither incurable nor treatable.

Very very few, if any at all. According to BSEinfo.org, cases are 1 case per million per year. And 87% of the cases happen in people over 50 years of age; the ratio for that is 3.4 cases per million per year. "In recent years, the United States has reported fewer than 300 cases of CJD a year." http://www.bseinfo.org/scieIncidenceCases.aspx

CJD appears to affect males and females in equal numbers. It usually first appears in mid-life, beginning between ages 20 and 68, with the average age at onset of symptoms being around age 50.

Currently there are no laws specifically on chronic wasting disease in the United States. There are guidelines and suggestions regarding how to protect yourself from the theoretical risks of CWD available through most States' Department of Wildlife.

My grandpa had cjd. You start losing your memory, and then you are put on bed rest. You can't move, talk, or open your eyes. He died in 2 months. So stfu , and never put the words cjd in your mouth.

Mad Cow Disease is a layman's term for Bovine Spongiform Encephalopathy.

The Mad Cows was created in 2000.

No. There are still cases that occur both in Canada and the USA, even though the cases that do occur in the states are never reported.
