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.

Rare ABCA7 gene variants linked to Alzheimer’s risk

A new study from MIT neuroscientists reveals how rare variants of a gene called ABCA7 may contribute to the development of Alzheimer's in some of the people who carry it.

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.

Berberine improves cognitive function in diabetic encephalopathy mice

A recent study published in Engineering has shed new light on the potential therapeutic effects of berberine (BBR), a natural compound derived from traditional Chinese medicine, in treating diabetic encephalopathy (DE).

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.

8 Sep 2025

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.

8 Sep 2025

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.

5 Sep 2025

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.

4 Sep 2025

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.

4 Sep 2025

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.

3 Sep 2025

Impaired spatial orientation found in older adults at risk for Alzheimer’s disease

Individuals with an increased risk for dementia due to Alzheimer's disease can have impaired spatial orientation skills.

3 Sep 2025

Genetic variant disrupts brain’s cleanup crew increasing Alzheimer’s risk

A Nature study published today and led by researchers at the University of South Florida's USF Health Byrd Alzheimer's Institute pinpoints how a genetic variant disrupts microglia - the brain's "cleanup crew" - increasing the risk of Alzheimer's disease.

3 Sep 2025

Epigenomic erosion linked to cognitive decline in Alzheimer’s patients

Most people recognize Alzheimer's from its devastating symptoms such as memory loss, while new drugs target pathological aspects of disease manifestations, such as plaques of amyloid proteins.

2 Sep 2025

New insights into early brain circuit breakdown in Alzheimer’s

One of the first parts of the brain affected by Alzheimer's disease is the entorhinal cortex - a region that plays a big role in memory, spatial navigation, and the brain's internal mapping system.
