Doctors Baffled, Intrigued By Girl Who Doesn't Age
phyrebyrd writes "Brooke Greenberg is the size of an infant, with the mental capacity of a toddler. She turned 16 in January. Brooke hasn't aged in the conventional sense. Dr. Richard Walker of the University of South Florida College of Medicine, in Tampa, says Brooke's body is not developing as a coordinated unit, but as independent parts that are out of sync. She has never been diagnosed with any known genetic syndrome or chromosomal abnormality that would help explain why. Brooke's hair and her nails are the only two things that grow, Howard said. 'She has pajamas and outfits that are 10 or 12 years old,' he said."
not that i know a damn thing about endocrinology, but i would speculate that this failed therapy suggest that, as we all have receptors for various hormones, her body has no such receptors for HGH. if someone is born genetically male, but has no male secondary characteristics, then either:
1. his body produces no testosterone,
2. his body produces testosterone, but his body doesn't react to it
i would say that this girl, uh, young woman, has an incredibly rare, unique mutation: insensitivity to human growth hormone. it would explain all of her symptoms

It just struck me reading that... it must really, REALLY suck being the first person to ever have a particular disease.
What if we have it backwards?
What if she is the first person not to have the disease we all have and that she is aging but really really slow?
So in 100 years she will have the body of an 18 year old?!
I mean if you think about it, old age is a disease.

So clearly an HGH deficiency isn't the (only) issue, it's that her HGH receptors don't respond to the hormone. But, to the best of my knowledge, that wouldn't account for a lack of mental development. This sounds like a combination of many factors coming together.
I'll have to take a look to see if there's anything written from a medical perspective (e.g., a journal paper) on this case. It could be interesting to hear what the doctors have to say, as opposed to what ABC News reports the poor mother has to say (projecting her wishes onto her daughter: thinking she's a rebellious teenager when really she's just an infant).
There is this girl/woman in Brazil, Maria Aldenete, who has similar syntoms. I couldn't find any info in English on her... She's 30 years old or so.
I went to HS with a girl who's older brother was the first ever case of a genetic disorder.
I can't remember their family name but it was named after her older brother, and she had it too. AFAIK, she and her brother are the only 2 documented cases of the disorder. They both had severe scoliosis, a lot of pain, some immune system disorders, and their abdomens were very short when compaired to the rest of their bodies (due to the scoliosis of the spine I assume). Having a disease named after their family was definitely not any sort of consolation either. She graduated first in her class, so it probably won't interfere with the rest of her life. She'll probably just have to explain about it to everyone she meets, and have some medical complications as she gets older and decides whether or not to have kids.

Another way of looking at aging is that the evolutionary race is to have children, as many as possible, as quickly as possible. Animals who sacrifice their long-term prospects in favor of getting to reproductive age more quickly, are likely to be highly competitive. There are a lot of biologists who claim there isn't any reason humans can't live as long as Galapagos Tortoises (who seem to live 200 or 300 years) but our environment doesn't select for old age. Anything you do after you've had some kids is just noise, as far as evolution is concerned. (Until, as you say, you develop culture and/or spend time caring for relatives' children, which tends to propagate your genes in a more diffuse manner.)

I have an aunt who was in her third trimester when she was in a car accident, and Dolly was born soon after with no apparent damage... except she never grew up. Dolly passed away a few years ago, at the age of 33, and weighed about 80 pounds - she did grow "up", but much slower than normal - she was 20 before she weighed 40 pounds, and never spoke a single intelligible word. She never matured mentally beyond around 6 months, and was always in a crib at all the family gatherings. Thankfully, I never had to change her diaper.
There are some differences, as Dolly did seem to physically mature, just very slowly - but the doctors didn't seem to think it was that phenomenal, just brain damage from the accident. She did have the same odd development that Megan's eyes have - the wandering eye, so to speak. (As opposed to my wandering eye, which is entirely a different sort of affliction.) :)

Her lack of mental development could be directly related to her lack of physical development, in that her brain is not physically developing to be able to learn and process information like everyone else's does. I'm by no means a doctor but I thought I'd throw that out there as a reasonable hypothesis.

In a couple of years, when she turns 18, would nudes of her be child porn? Eh?

But maybe with her "normal" growth is considered damage and thus "fixed".
Just like the brain tumour that appeared and vanished, any parts that try to go "next stage" get repaired.

But I think we *have* created an environment that does, by building such intricate communities and engaging so heavily in health care and stuff. There are very, very, very few animals that have longer average lifespans than humans. (Sharks, tortoises, and possibly some parrots, are the only ones that come to mind, and I *believe* those are mostly because those are animals that have little predation in their natural environments, so they have less need to reproduce as quickly as possible.)
One thing about evolution that isn't well-understood by the world at large, is that it has to work with what it currently has. Humans aren't likely to develop the ability to see electric fields any time soon, because there's no existing framework. We have trillions of generations of ancestors focussed on reproducing quickly because they lived in environments where that was favored. It's difficult to find a path that diverges from such a strong existing trend: there's very little to work with.
Plus, there are a number of different aging mechanisms. It's a weakest-link-of-the-chain sort of situation. The mechanisms tend to all equilibrate at one general area, as a result of neutral genetic drift (if one aging mechanism tends to kill people at 90 and another at 140, the one at 140 has nothing pushing it to stay there so it can drift down to 90 without affecting anything; over time it will probably tend to do this. Repeat with a half-dozen mechanisms that seem to be indicated in aging.)
Which is all a very long way of saying that I'm guessing we're in an ecological niche that does select for longer lifespans, and we're seeing the results of it, but our genes don't give evolution a lot of material to work with so we might not get much more than we currently have.
