Researchers develop a digital cognitive test for diagnosing Alzheimer's disease

Researchers at Lund University in Sweden have developed a digital cognitive test for diagnosing Alzheimer's disease that is intended for use in primary care.

Caregiver personas offer insights for improving dementia medication management

Understanding the strategies and unmet needs of caregivers managing medications for people with Alzheimer's disease or related dementias may improve the lives of both caregivers and patients.

UCL launches landmark trial of Alzheimer’s blood test

A major UCL-led clinical trial, aiming to transform the diagnosis of Alzheimer's disease through a simple blood test, is now welcoming its first participants who will be recruited via memory clinics across the UK.

Object recognition shapes spatial awareness in the brain

We take our understanding of where we are for granted, until we lose it. When we get lost in nature or a new city, our eyes and brains kick into gear, seeking familiar objects that tell us where we are.

Compact bNIRS technology could become a diagnostic toolkit for dementia

Early and accurate diagnosis of dementia remains a major challenge. Standard approaches such as MRI and PET scans can provide valuable information about brain structure and function, but they are expensive, not always accessible, and often too expensive for repeated use.

SLIT2 protein levels in the eye and blood linked to cognitive function

Neurocognitive impairments are classified by pathological changes with potential for destruction of neural tissue. One change known to occur in neurodegenerative disorders is an accumulation of proteins causing pathological damage.

Chronic insomnia linked to faster cognitive decline and brain changes

People with chronic insomnia may experience faster declines in memory and thinking skills as they age-along with brain changes that can be seen on imaging scans-than people who do not have chronic insomnia, according to a study published in the September 10, 2025, issue of Neurology, the medical journal of the American Academy of Neurology.

Can video game–style exercise slow Alzheimer’s risk?

Gamified exercise training improves hippocampal volume and cognitive performance in mild neurocognitive disorders, offering potential for dementia prevention.

Special MRI technique predicts onset of mild cognitive impairment and cognitive decline

A special MRI technique that detects iron levels in different regions of the brain can predict the onset of mild cognitive impairment and cognitive decline in cognitively unimpaired older adults, potentially creating a pathway to earlier interventions, according to a study published today in Radiology, a journal of the Radiological Society of North America.

Dementia risk rises sharply with multiple psychiatric disorders

The odds of developing dementia are strongly linked to the number of co-existing mental health disorders, rising from twice as high for one disorder to 11 times as high for four or more, finds research published in the open access journal BMJ Mental Health.

Changing indoor environments could improve sleep for people living with dementia

Implementing changes to indoor environments, such as cooler bedrooms at night and increasing the amount of bright light during the day, could significantly improve sleep for people living with dementia, according to a study led by the University of Surrey.

Air pollution exposure linked to faster progression of Alzheimer’s disease

Exposure to high concentrations of air pollution may worsen Alzheimer's disease (AD) by accelerating the buildup of toxic proteins in the brain and speeding up cognitive decline.

Study could pave the way for simple blood test to diagnose Alzheimer's disease

In a landmark study of Hispanic and Latino adults, researchers at University of California San Diego School of Medicine have identified a link between self-reported cognitive decline and blood-based biomarkers, which could pave the way for a simple blood test to help diagnose Alzheimer's disease and related dementias.

EEG ‘Fastball’ shows promise for spotting early memory loss in Alzheimer’s

This study introduces Fastball, an EEG method that accurately measures recognition memory in MCI, enhancing early dementia diagnosis and cognitive assessment.

Creatine increases muscle strength in Alzheimer’s patients

Research indicates that creatine may enhance muscle strength and size in Alzheimer's patients, suggesting a viable approach for mitigating muscle loss.

Blood-based biomarkers reveal barriers to diversity in Alzheimer’s disease trials

Some of the populations with the highest risk for Alzheimer's disease remain greatly underrepresented in clinical trials-and a new study helps explain why.

Study finds possible molecular connection between air pollution and Lewy body dementia risk

A team of researchers found there is a possible molecular connection between air pollution and an increased risk of developing Lewy body dementia.

Smell loss emerges as the early behavioural sign of Alzheimer’s

Research reveals immune cells target brainstem nerves, linking smell loss to early Alzheimer's, offering potential for earlier diagnosis and intervention.

Study finds universal rise in cholesterol after menopause among Bolivian Tsimane women

Deep in the Bolivian Amazon exists a forager-horticultural community called the Tsimane. Researchers look to them for insights on how the human body functioned prior to modern technologies, as their lifestyles remain the closest to that of our ancestors.
