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."

The rebels of the Free Syrian Army recently retook the small farming village of Khirbet al-Joz, just across the border from Turkey. Soon after, Syrian men who had been in Turkish refugee camps returned to the village to see what had happened to their homes.
