The FDA has approved the first new Alzheimer's drug in nearly 20 years. Stephen Salloway digs into what it means for patients and for the disease's future.

Researchers have conducted an early human trial for a light- and sound-based treatment for Alzheimer's disease. The results are promising, they say.

Increases in "bad" bacteria and decreases in "good" bacteria in older adults' gums is associated with a biomarker for Alzheimer's disease, researchers find.

"...this pollution is everywhere and could explain the increased number of people impacted by Alzheimer's disease across the world."

A new study that links specific gut bacteria to neurodegenerative diseases could one day lead to treatments for Alzheimer's, Parkinson's, and ALS.

Experimental Alzheimer's drugs have shown little success in slowing the disease. New research in mice shows that unclogging the brain's "drain" may help.

"...there's hope that through targeted play we will be able not only to delay but also weaken the symptoms of dementia."

"If we can develop more ways to identify lung cancer earlier, that may open the door for treatments that greatly improve the survival rate."

A new study in mice shows how aging affects stem cells in the brain, as well as how to reactivate the production of neurons.

A new study with mice offers a promising way to potentially restore cognitive function loss due to Alzheimer's disease, researchers report.
