A new brain scan tool shows how quickly your body and mind are aging. It can spot early signs of diseases like dementia, long before symptoms begin. The scan looks at hidden clues in your brain to ...
Scientists have uncovered a surprising sugar-related mechanism inside brain cells that could transform how we fight Alzheimer’s and other dementias. It turns out neurons don’t just store sugar ...
USC researchers have found a promising new brain scan marker that could better detect Alzheimer’s risk — but only for some. The tau-based benchmark works in Hispanic and White populations when paired with another Alzheimer’s protein, amyloid, ...
Our brains may work best when teetering on the edge of chaos. A new theory suggests that criticality a sweet spot between order and randomness is the secret to learning, memory, and adaptability. ...
A simple blood test could reveal which early Alzheimer’s patients are most at risk for rapid decline. Researchers found that people with high insulin resistance—measured by the TyG index—were four times more likely to experience faster ...
USC researchers have uncovered a hidden driver behind the early and severe onset of Alzheimer's in people with Down syndrome: iron overload in the brain. Their study revealed that individuals with ...
A team of scientists has discovered a direct link between the smell of food and feelings of fullness at least in lean mice. This brain circuit, located in the medial septum and triggered by food odors, helps animals eat less by making them feel ...
A new way of thinking about Alzheimer's disease has yielded a discovery that could be the key to stopping the cognitive decline seen in Alzheimer's and other neurodegenerative diseases, including ALS and ...
Researchers have released the full dataset from the Dallas Lifespan Brain Study, a decade-long project designed to track brain and cognitive health as people age and distinguish neurologically healthy paths from those indicating a likelihood of ...
Obesity is a global health problem that affects many people. In recent years, very promising anti-obesity drugs have been developed. Despite these successes, there are patients who do not respond to these drugs or suffer from side effects. ...
Humans and mice share persistent brain-activity patterns in response to adverse sensory experience, scientists find, opening a window to our emotions and, perhaps, neuropsychiatric ...
A newly refined method for measuring the Pace of Aging in population-based studies provides a powerful tool for predicting risks associated with aging, including chronic illness, cognitive ...

A new study examines the choices healthy research volunteers make when given the opportunity to learn their risk of developing Alzheimer's disease dementia. The researchers found a large ...

Reduced levels of a critical protein are linked to devastating brain diseases like Alzheimer's, frontotemporal dementia, and amyotrophic lateral sclerosis (ALS). Surprisingly, the protein ...

An increase in physical activity between the ages of 45 and 65 could help prevent Alzheimer's disease, while inactivity may be detrimental to brain ...

Recently approved Alzheimer's drugs offer a step forward for treating the disease, but new therapeutic strategies are needed to complement them and provide personalized therapeutic approaches. ...

Prions transmit their abnormally folded shape onto other proteins. Researchers designed a synthetic fragment of the tau protein that exhibits prion-like behavior. Misfolded tau proteins are the ...

A new study found that a gene recently recognized as a biomarker for Alzheimer's disease is actually a cause of it, due to its previously unknown secondary function that triggers a pathway that ...

In a landmark clinical trial people at risk for Alzheimer's who exercised at low or moderate-high intensity showed less cognitive decline when compared to those receiving usual ...

We know exercise is good for our body, but what about our brains? A new study suggests that exercise plays a crucial role in keeping our minds sharp, even when one of the brain's key energy ...

Researchers hope to launch human clinical trials in their quest for a vaccine to prevent the buildup of pathological tau after demonstrating that this vaccine generated a robust immune response in ...

While a comprehensive cure-all to these neurological conditions is unlikely, scientists are making headway into understanding their fundamental characteristics with the hope of preventing or ...

People with Alzheimer's disease may retain their ability to empathize, despite declines in other social abilities, finds a new ...

A new study suggests that risk factors and biomarkers related to Alzheimer's disease are associated with cognition much earlier in life than previously recognized. The study highlights ...

A new way to deliver disease-fighting proteins throughout the brain may improve the treatment of Alzheimer's disease and other neurological disorders, according to scientists. By engineering ...

A new study provides solutions to the pressing need to identify factors that influence Alzheimer's disease (AD) risk or resistance while providing an avenue to explore potential biological ...

A new study has found important clues about the roles age, sex, hormonal changes and genetics play in how certain biomarkers for dementia are expressed in the blood, according to a new ...

Individuals with a genetic predisposition to Alzheimer's disease show altered blood levels indicating damaged neuronal contacts as early as 11 years before the expected onset of dementia ...

A research team has identified a previously unknown enzyme, SIRT2, that plays a key role in memory loss associated with Alzheimer's disease (AD). The study provides critical insights into how ...

Heavy drinkers who have eight or more alcoholic drinks per week have an increased risk of brain lesions called hyaline arteriolosclerosis, signs of brain injury that are associated with memory and ...

While some studies have suggested that having a mother with Alzheimer's disease may put you more at risk of developing the disease, a new study finds that having a father with the disease may be ...

Researchers have discovered a new way that neurons act in neurodegeneration by using human neural organoids -- also known as 'mini-brain' models -- from patients with frontotemporal lobar ...
