Treatment for Alzheimer's probably needs to begin years or even decades before symptoms of the disease start to appear, scientists reported at this week's Society for Neuroscience meeting in New Orleans.
"By the time an Alzheimer's patient is diagnosed even with mild or moderate Alzheimer's there is very, very extensive neuron death," said John Morrison of Mount Sinai Medical School in New York. "And the neurons that die are precisely those neurons that allow you to navigate the world and make sense of the world."

It is now clear that we are living in a world of viral memes that take no sides when it comes to spoofing politicians or debate moderators.
So what's a politician to do as the target of a social media parody?
Run with it.
"By kind of winking along with the electorate, you're humanizing, personalizing yourself, authenticating yourself," says Rory O'Connor, author of Friends, Followers and the Future. O'Connor argues that social media will be critical to deciding who is elected as the next president.
It's midday in the cafeteria of the Israeli parliament, or Knesset, and legislators and their aides are busy wheeling and dealing over lunch.
Gil Hoffman, political analyst for The Jerusalem Post newspaper, surveys the cafeteria floor with an expert's eye.
"Never a dull moment in election season," he says. "This is where the politicians, when there is something really important to get across to the press, this is where they do it; this is where they meet and make whatever political deals they need to get ahead."
Pakistan is one of the remaining corners of the world where polio still lingers. Last year, the government declared a national emergency, and with the help of international institutions, embarked on an aggressive vaccination campaign.
So far, the results have been promising. The number of new polio cases is about a third of last year's total of 198.
But the new campaign, like previous efforts, hasn't been able to overcome one critical problem: getting into parts of Pakistan's lawless tribal regions along the border with Afghanistan to vaccinate the children there.
Manssor Arbabsiar, an Iranian-born naturalized American citizen, has pleaded guilty to conspiring with Iranian military officials in a plot to kill the Saudi ambassador to the United States, the Justice Department says.
While much of America was watching the second presidential debate, about 2,000 people — many of them between the ages of 20 and 40 — were doing something very different. They had gotten a rare and prized ticket to the only U.S. appearance by J.K Rowling, as she promotes her new book for adults, The Casual Vacancy.
The crowd was huge but happy — double the number originally planned, forcing the organizers to change venues. Attendees got a ticket to the Lincoln Center event and a copy of the book, which Rowling would later sign.
César Aira's The Miracle Cures of Dr. Aira is only 80 pages long, but, like many of his books, it reads with the intensity and fullness of a much longer novel. In it you'll find an eccentric flaneur, an evil archenemy, a vicious guard dog, an ambulance that goes only in a straight line.
Dr. Aira, the main character, likes to wander the streets of a town called Pringles. That this happens to be the name of the author's hometown in Argentina may or may not be significant. As he walks, he thinks up theoretical miracle cures to imagined illnesses.
Think you're part of the food-literati? True or false: 13 million more acres of farmland would be required to produce enough fruit and vegetables for the daily diets of all Americans to meet U.S. Department of Agriculture nutrition guidelines.
