Mad human disease?

grapefruitmoon — Fri, 05 Jan 2007 14:58:15 -0800

In the new book The Family That Couldn't Sleep, journalist D.T. Max investigates Fatal Familial Insomnia - a strange prion disease that has been linked to Variant Creutzfeld-Jakobs Disease (the human form of mad cow disease).

The links between the diseases are fascinating, as are the implications for how disease can spread. Perhaps most fascinating is the reason why most of the world has NOT as of yet died of mad cow disease. (I'm not going to spoil it for anyone who wants to read the book.)

Sweet Jesus on a pogo stick that's nightmarish. Okay, poor word choice.

Wow. Absolutely amazing, and horrific. Thanks for that post.

This is so weird.. I heard about this on NPR a coule of weeks ago, and was talking about it last night to some friends. It is so creepy.

(I'm not going to spoil it for anyone who wants to read the book.) This isn't fiction, and you've piqued my curiousity. Please, spoil.

I'll pass on all prion-related diseases, thanksverymuch.

cortex: I'll try to explain as eloquently as I can, but IANAS. Genetics dictates that we have two copies of each chromosome - one from each parent. Prion diseases are more common in people who have different amino acids in the "prion space" on each copy of the chromosome that controls that sort of thing (20 or 21, I can't remember which). Thankfully, the reason we're not all dead of CJD is that the vast majority of the population has the same amino acid on both prion chromosomes. Investigation into why evolution would have selected for this has speculated that mass cannibalism may have wiped out many of those prone to CJD around 800,000 BCE. (CANNIBALISM! Doesn't get much creepier than that. Man, I love creepy stuff.)

so, here's an idea -- if you're genetically predisposed to a really fucked up disorder and you know it, based on your family's history DON'T BREED; unless you want to make your children suffer an agonizing life.

if you're genetically predisposed to a really fucked up disorder and you know it, based on your family's history DON'T BREED A simple solution to a simple problem. Entirely acceptable and complete.

wumpus, thanks to the wonder of eugenics, your recommendation will be willfully misconstrued. of course, there's also the argument that asking someone not to breed is akin to asking someone not to breathe (since, well, humans as a species are preprogrammed to have the urge to breed, hence the sex drive). but, anyway.

By: lisalisa123

lisalisa123 — Fri, 05 Jan 2007 16:38:37 -0800

i'd think it would be 20 since 21 is the sex chromosome.

Arguably, humans are preprogrammed to have the urge to fuck (hence the propogation).

When the zombie outbreak occurs, it will surely be in the form of a prion disease. That being said, this sounds truly horrible.

okay, let's get into responsible procreation a little. i actually agree with wumpus- alot. for several reasons. why would anyone want to have a child, knowing that the kid would be living a horror of a life? there are children who live horrible lives, but this particular condition is just torture and needless if it can be avoided. adoption might be a solution for people who are capable of managing such a disease. adoption solves 2 problems: it ceases the genetic anomoly, helps stop world overpopulation. humans as a species are preprogrammed to have the urge to breed, hence the sex drive and there is birth control to help prevent accidents. of course people are going to have sex and a sex drive! however, the need to procreate, although biologically is a necessity, is not logically a necessity for the survival of the species. edward o. wilson makes a point in an interview on the think tank about his bottleneck theory, and how our population explosion will become a regression in a few years.

Ha! I gave this book to my sister for Christmas. Apparently there is a sheep disease called lickybutt or something like that.

By: thirteenkiller

thirteenkiller — Fri, 05 Jan 2007 16:59:17 -0800

Also, wumpus, the people with this insomnia disease don't develop symptoms till late middle age or after, and then they die fairly quickly. So it's not like they're dooming their children to a lifetime of suffering.

The sheep disease is called scrapie. /pedant

Oh, actually, the disease is Licky End. Jedi, you know, there is more than one sheep disease.

By: thirteenkiller

thirteenkiller — Fri, 05 Jan 2007 17:18:41 -0800

But Licky End may have been made up by Terry Pratchett and it probably isn't covered in the book in question. /shifty look

This is so terrifying I can't help myself from laughing maniacally. I go through some pretty severe bouts of insomnia, and I actually got to level two where my hallucinations and panic attacks started interfering with my life (winter in Inuvik fucked me up badly). Dying of insomnia, slowly going crazy, is my idea of hell. These poor people should be allowed euthanasia (if they want it) once the disease progresses to the batshitinsane level.

lisalisa123 writes "i'd think it would be 20 since 21 is the sex chromosome." Not in humans, it isn't. 21 is the chromosome responsible for trisomy 21 (Down syndrome).

why would anyone want to have a child, knowing that the kid would be living a horror of a life? there are children who live horrible lives, but this particular condition is just torture and needless if it can be avoided. Well, the child wouldn't live a horror of a life at all. This is a horrible, godawful way to DIE, but the disease has little to no bearing on one's life up until that point. Also, this disease has been haunting the family in question for centuries. Only recently have the mechanisms of disease transmission been understood well enough for families to make informed choices about adoption. The author discusses the ethics of this, and the family has chosen to remain in the dark (so to speak) about who has the mutation that causes the disease so that it won't be a factor in their decisions to have children. Yes, it's an awful way to die and I don't know if I would want to continue the disease, but it's extremely rare (it doesn't even occur in *all* members of the family) and life up until the onset of the disease (around age 50) is completely normal.

A comment regarding prions... From the third (wikipedia) link: "The mutation changes the shape of the protein so that it becomes a prion and makes other, normal protein molecules change to the abnormal shape." (helpful image here). This is know as the Prion Hypothesis, and as yet still remains a hypothesis. It's still somewhat controversial, and nobody has yet proven that it really occurs. The scientist who does prove it (assuming it's true), will probably get a Nobel Prize.

By: grapefruitmoon

So far, two Nobel prizes have already been given out based on prion research: Daniel Carleton Gajdusek and Stanley B. Prusiner.

Apparently scientists have already genetically-engineered cows that are supposedly not susceptible to BSE because they lack the protein that the prions fuck up.

So...I'm confused. Are these people becoming ill from lack of sleep, or is lack of sleep one characteristic of an illness that causes many symptoms? This journal article makes it sound like a LOT is wrong with their bodies besides just not sleeping.

By: kindall

kindall — Thu, 11 Jan 2007 20:59:23 -0800

The lack of sleep is indeed a symptom. Of holes in their brain.
