Study reveals racial differences in early Alzheimer's brain changes

A team of researchers at the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC has identified important differences in how early Alzheimer's disease-related brain changes appear across racial and ethnic groups, underscoring the need for more inclusive approaches to studying and diagnosing the disease.

New study identifies specific brain cells most vulnerable to ALS and dementia

Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) belong to a spectrum of neurodegenerative diseases with overlapping symptoms, characterized by muscle wasting, paralysis, dementia, and other serious impairments.

Everyday wearable data could reveal early brain health signals

Wearable sensors combined with AI offer a novel approach to continuous monitoring of cognitive and emotional health, detecting early changes in brain function.

MUSC’s new manual for navigating dementia

For an estimated 11% of Americans over age 65 who have dementia and the over 11 million unpaid caregivers supporting them, there is no instruction manual for navigating life after diagnosis. A team of College of Nursing researchers at the Medical University of South Carolina is working to fill that gap.

Blood test marker p-tau217 helps detect early dementia risk in cognitively healthy older women

A long-term study of 2,766 women in the Women’s Health Initiative Memory Study found that higher baseline plasma p-tau217 levels were associated with a greater risk of developing mild cognitive impairment or probable dementia.

How the aging gastrointestinal tract drives age-related cognitive decline

We become forgetful as we age. This is often seen as a universal truth, but in fact it is far from universal: some people remain incredibly sharp at 100 years old, while others experience memory loss starting in middle age.

Blood marker linked to Alzheimer’s also found in systemic amyloidosis

A certain blood protein regarded as an early indicator of Alzheimer's disease also appears to play a role in other disorders.

Wegovy linked to higher risk of eye stroke and vision loss

Wegovy, a GLP-1 agonist for weight loss, may carry the highest risk of 'eye stroke' (ischemic optic neuropathy) and sudden sight loss of the semaglutide drugs, finds an analysis of unintended side effect reports published in the British Journal of Ophthalmology.

Study links p-tau217 levels to long-term dementia risk in women

Researchers from the University of California San Diego have found that a novel blood-based biomarker can predict a woman's risk of developing dementia as many as 25 years before symptoms appear.

Air pollution may be lowering global IQ and widening inequality, researchers warn

Researchers argue that exposure to fine particulate air pollution (PM2.5) may affect cognitive function and intelligence, potentially causing large population-level losses in global IQ. Using modelling based on published exposure–response data, the authors estimate that pollution could be associated with tens of billions of IQ points lost worldwide, with the largest impacts in lower-income regions.

How social and environmental exposures across life influence mental health risk

Researchers outline how the exposome framework, which captures the totality of environmental exposures across the lifespan, can help explain how non-genetic factors shape mental health risk and resilience. The perspective highlights how integrating environmental, biological, and social data could improve prevention strategies, research models, and personalized mental health care.

Immune cells found to actively promote plaque formation in Alzheimer’s disease

A new study led by researchers from VIB and KU Leuven shows that immune cells called microglia can actively promote the formation of plaques in Alzheimer's disease, challenging the long-standing view that these cells serve only as defenders against plaque buildup.

Researchers develop DNA aptamer to detect Alzheimer's biomarkers

With aging populations on the rise, the need for better tools to diagnose and monitor Alzheimer's disease (AD), the most common cause of dementia, has never been more urgent.

Banks are becoming bulwarks against scams for vulnerable seniors

The first call came just before Thanksgiving last year. She didn't recognize the phone number, but she answered anyway.

Spiritual care should be routine for patients with neurological diseases

People living with neurological diseases such as Parkinson's disease, dementia and epilepsy face not only physical decline, but also profound questions about identity, purpose, and meaning.

Unmasking the hyperactive circuitry of early Alzheimer’s

Neuroscientists at King's College London have pinpointed a mechanism behind the increased neural connectivity observed in the very early stages of Alzheimer's disease.

Redefining the "aging brain" through diverse data

Age is more than just one number. While neuroscientists used to think of cognitive aging as a single trendline, they now realize that vast individual differences require a more predictive and personalized approach. As they uncover more factors that affect cognition over time, they are realizing that modeling the aging brain requires more diverse data than traditionally captured.

Modified psilocybin compounds may treat brain disorders with fewer hallucinations

Psilocybin - the psychoactive compound in "magic mushrooms" - is gaining scientific attention for its potential in treating neuropsychiatric conditions including depression, anxiety, substance use disorders and certain neurodegenerative diseases.

Tubulin prevents toxic protein clumps linked to neurodegeneration

Researchers at Baylor College of Medicine have discovered a potential new strategy to fight back against Alzheimer's and Parkinson's diseases, conditions that are linked to the toxic accumulation of Tau and alpha synuclein protein clumps in the brain.

Brain cells amplify important signals to guide focus and navigation

Nerve cells in the brain are constantly bombarded with information from different senses simultaneously. How can the brain prioritize what is most important?
