Mild Memory Loss Is Not a Part of Normal Aging, New Research Finds

* his amazement when he learned that somebody had received a radio signal that was bounced off of the moon
* he worked on a trans atlantic ship in his teenage years during prohibition, and had his first beer in Germany at the age of 16
* depression era job prospects
* walking home from a "picture" after his car was stolen, he and a few friends heard his horn (which was somehow identifiable). They were track runners, so they ran down the car and it turns out it was a young guy who had just borrowed it to go visit his girlfriend, and was on his way to return it.
* his godfather was a civil war vet
My grandfather could tell us all kinds of interesting tales in his old age, but then not remember what he ate for breakfast.
If it's something that happens almost universally to brain structure as a function of age, in what sense is it not normal? That doesn't mean we shouldn't still improve it / stave it off / etc., but I'd classify that more as, "we've found a way to stop the process by which elderly normally suffer reduction in memory function".
Sort of how you might say: rubber normally gets brittle as it ages, but with this new coating, that process is stalled. But that's different from saying: "hey, new discovery, rubber actually doesn't normally get brittle as it ages!" I was expecting something like that from the headline, so was expecting a study that found that e.g. memory loss among the elderly was much less common than popularly assumed.
"The process of declaring parts of aging as a disease is driven by regulation: the FDA does not permit treatments for aging, only for named diseases. Since there is little funding for research that cannot be legally commercialized, the incentive is to carve off chunks of the process of aging and go through the process of having government employees add it to the list of diseases - which can take years and millions of dollars. Sarcopenia, for example, is still not recognized by the FDA, meaning that no potential treatment can be commercially developed in the US. Here is an example of this process at work for memory loss."
So I claim that the question is not "how many billions of dollars to allocate to anti-aging research".
The real question is how to get government and politics out of the system. They're the ones that are getting everything discombobulated.
Let people speak with their own actions (and wallets) about how much resource should be allocated to various areas of medical research.

If you follow the links, one of the large slices you don't account for is "high-risk heterosexual contact", which makes up about 1/3 of new HIV infections. That's people who are not part of one of the high-risk groups, but have had at least one partner who was (which may or may not have been known to them). So the proportion of people who have some rational reason to worry is relatively high, unless you are absolutely sure that none of your sexual partners have themselves ever belonged to one of the high-risk groups. That's a particularly common route of HIV infection among women, since not all bisexual men self-identify as bisexual or disclose that part of their sexual history to female partners.
But the threat that AIDS represents is much larger. Why spend a lot of resources fixing a tiny hole on a large boat? The hole isn't leaking much? Well, it's the scary potential that mandates treatment and prevention.
If we assume that HIV rates among blacks are distributed the same way as in the general population, then we find that black gays alone account for about 40% of HIV infections in 2008, while making up 0.1-0.3% of the population. Unfortunately, the data I linked to is not granular enough to prove this.
A comparison: gay sex was about 55-170x more dangerous than straight sex in 2008 (depending on whether 3% or 1%of america is gay). Unprotected sex is only about 6-20x more dangerous than sex with a condom (depending on which set of wikipedia numbers you pick).
When government payments fund the livelihood of retired folks, there is a financial disincentive to fund "anti-aging" research.
Laws will change when the population changes enough.
I would mention though, that the process of reclassifying conditions as diseases is also driven by the desire for commercialization itself.
Even if the FDA did permit treatment for aging, such treatment could be seen "bleeding edged" or "unnatural" and have a smaller audience. If a symptom of aging could be classified as a disease, a person will have not only the option to obtain treatment but the obligation.
"Bob, you have not been getting treatment for your winkle-itis, don't you think that's bit irresponsible?"
>almost no gradual decline was seen in the absence of lesions.
Where lesions are specific damages to the brain, not aging.
