New therapeutic molecules show promise in reversing the memory loss linked to depression and aging. These molecules not only rapidly improve symptoms, but remarkably, also appear to renew the underlying brain impairments causing memory loss in preclinical models.

An international research team has created a better understanding of Alzheimer's. They have shown that the cleaning system of the brain cells, the so-called mitophagy, is very weakened in animals and humans with Alzheimer's. And when they improve the cleaning…

Scientists have shown for the first time that a blood-clotting protein called fibrinogen is responsible for a series of molecular and cellular events that can destroy connections between neurons in the brain and result in cognitive decline.

Exercise training alters brain blood flow and improves cognitive performance in older adults, though not in the way you might think. A new study showed that exercise was associated with improved brain function in a group of adults diagnosed with…

High levels of a satiety hormone could decrease a person's likelihood of developing Alzheimer's disease. For individuals who have higher levels of the hormone, their chance of having mild cognitive impairment or Alzheimer's disease decreased by 65 percent.

Researchers report that autopsies of patients diagnosed with Alzheimer's disease when they were alive -- and confirmed by autopsy -- indicate many cognitive issues symptomatic of the condition are less noticeable in living Hispanic patients.

A study in mice and people shows that sleep deprivation causes tau levels to rise and tau tangles to spread through the brain. Tau tangles are associated with Alzheimer's disease and brain damage.

Scientists have shown that a protein found in the blood can be used to precisely monitor disease progression of Alzheimer's long before first clinical signs appear. This blood marker offers new possibilities for testing therapies.

New research suggests that frailty makes older adults more susceptible to Alzheimer's dementia, and moderates the effects of dementia-related brain changes on dementia symptoms. The findings suggest that frailty should be considered in clinical care and management of Alzheimer's dementia.
