No health without brain health

A largely aged population is already a reality in some countries, and this will become a worldwide problem by 2047, when the number of the Earth’s old people is likely to surpass the number of young people.

Preventing Alzheimer's

$20 million lifestyle intervention trial to prevent cognitive decline

The Alzheimer's Association announced the launch of a $20 million U.S. two-year clinical trial to test the ability of a multi-dimensional lifestyle intervention to prevent cognitive decline and dementia in 2,500 older adults with no current cognitive symptoms but who are at increased risk for later cognitive decline. The announcement was made at the 2017 Alzheimer's Association International…

Detecting Alzheimer's disease before symptoms emerge

Long before symptoms of Alzheimer's disease become apparent to patients and their families, biological changes are occurring within the brain. Amyloid plaques, which are clusters of protein fragments, along with tangles of protein known as tau, form in the brain and grow in number, eventually getting in the way of the brain's ability to function. These biological changes can be detected early in…

New insights into early cognitive markers of Alzheimer's

New research led by the University of Hertfordshire, may significantly change the understanding of cognitive processes that are most impaired at very early stages of Alzheimer's disease. The findings could potentially be used to detect the condition at an earlier stage and improve diagnostic accuracy, by creating new cognitive tests that are more sensitive to brain pathology than ones currently…

Molecular Roots of Alzheimer’s

Scientists at Washington University School of Medicine in St. Louis have detailed the structure of a molecule that has been implicated in Alzheimer’s disease. Knowing the shape of the molecule — and how that shape may be disrupted by certain genetic mutations — can help in understanding how Alzheimer’s and other neurodegenerative diseases develop and how to prevent and treat them.

Predict early stages of Alzheimer’s disease

Researchers from Columbia University Medical Center (CUMC), New York State Psychiatric Institute, and NewYork-Presbyterian reported that an odor identification test may prove useful in predicting cognitive decline and detecting early-stage Alzheimer’s disease. Their two studies, presented at the Alzheimer’s Association’s International Conference in Toronto, Canada, suggest that the…

Neurodegenerative diseases

The case of the sticky protein

Proteins are like a body’s in-house Lego set. These large, complex molecules are made up of building blocks called amino acids. Most of the time, proteins fold correctly, but sometimes they can misfold. This misfolding causes the proteins to get sticky, and that can promote clumping, or aggregation, which is the hallmark of several neurodegenerative diseases such as ALS, Alzheimer’s and…

Retrograde amnesia

Researchers retrieve “lost” memories

Retrograde amnesia is the inability to recall established memories. In humans, amnesia is associated with traumatic brain injury, Alzheimer’s disease, and other neurological conditions. Whether memories lost to amnesia are completely erased or merely unable to be recalled remains an open question. Now, in a finding that casts new light on the nature of memory, researchers from the RIKEN-MIT…
