Eight people who received growth hormone treatments made from human brains died decades later from a rare disease. Some also had brain damage similar to that seen in Alzheimer's, autopsies reveal.

A new experimental drug is designed to slow down Alzheimer's by protecting brain cells from toxins associated with the disease. That's a different approach from other Alzheimer's drug...

Oliver Sacks, a neurologist and best-selling author who explored the human brain one patient at a time, has died of cancer. He was 82.

Sacks was best known for his books The Man Who Mistook His Wife for a Hat and Awakenings, which became a 1990 feature film starring Robin ...

A lack of sleep can increase the risk of traffic accidents, heart attacks, diabetes and maybe even Alzheimer's disease, research suggests. Yet most people with sleep disorders don't get treatment.

Try to look inside the brain, and you're not going to get very far. But photoacoustic imaging may be a solution for the shortcomings of conventional imaging. It uses lasers to make the brain sing.

A very rare genetic mutation causes some people to develop Alzheimer's in their 30s. It also makes these people the ideal candidates for tests of potential Alzheimer's drugs.

Researchers at the Alzheimer's Association International Conference say there's growing evidence that women are more likely than men of the same age to develop Alzheimer's disease.

By targeting the process that creates toxic clumps of protein in brain cells, scientists hope to help not just Alzheimer's patients, but perhaps also people with Lewy body dementia and Parkinson's.

Why do screams demand our attention like no other sound? The answer seems to involve an acoustic quality called roughness that triggers fear circuits in the brain.

The latest accomplishment for gene therapy involves mice with inherited deafness. Meanwhile, the drugmaker Novartis is conducting the first trial of gene therapy for people with hearing loss.

When people saw photos that linked a famous person with a famous place, it changed the behavior of certain neurons in their brains. And it changed their memories, too.

Hollywood's version of science often asks us to believe that dinosaurs can be cloned from ancient DNA (they can't), or that the next ice age could develop in just a few days (it couldn't).

But Pixar's film Inside Out is an animated fantasy that remains remarkably true to what ...

That's what researchers found when they gave chimps a device that appeared to work like an oven. The findings add to the argument that our ancestors began cooking soon after learning to control fire.

Antidepressant drugs that work in hours instead of weeks could be on the market within three years, researchers say.

"We're getting closer and closer to having really, truly next-generation treatments that are better and quicker than existing ones," says Dr. Carlos Zarate, a researcher at the National Institute of ...

After swapping hearing aids for a cochlear implant, Sam Swiller's taste in music shifted dramatically, from grunge rock to folk. Now scientists are trying to improve how implants relay music.

Researchers in Seattle are busy cataloging what scientists have learned. For now that includes detailed information on 240 mouse cells. Next up: a data trove of details on human brain cells.

On April 27, 1865, a steamboat named the Sultana exploded and sank while transporting Union soldiers up the Mississippi. An estimated 1,800 people died, but few today have heard of this disaster.

A doctor-scientist's long quest to help children with a rare form of brain cancer has led to the discovery that high levels of brain activity can make glioma tumors grow faster.

No wonder the brain needs so much energy. The same coordinated activity that allows you to retrieve a specific memory, like what you had for breakfast, continues at rest and even during sleep.
