Your Biological Age Could Predict Dementia Risk

A large study found that people whose biological age exceeds their chronological age are about 30% more likely to develop dementia. Biological age, measured through biomarkers like lung function and cholesterol, reflects how the body's systems are aging.

Metabolic Syndrome in Midlife Linked to Higher Dementia Risk

A large-scale study has found that having metabolic syndrome in midlife—marked by excess belly fat, high blood pressure, and abnormal cholesterol or blood sugar—is associated with a significantly higher risk of developing young-onset dementia before age 65. The analysis, based on nearly two million people, showed that the more components of metabolic syndrome a person had, the greater their dementia risk, with women and those in their 40s being most vulnerable.

How Age, Sex, and Genetics Shape Blood Biomarkers for Dementia

A new study reveals how age, sex, menopause, and genetics influence key blood biomarkers linked to dementia risk. Researchers analyzed data from over 1,000 people, measuring three biomarkers over a 17-year period and comparing results between those who developed dementia and those who did not.

This shows two heads, brains and a glass.

Heavy Drinking Linked to Brain Lesions and Cognitive Decline Risk

Consuming eight or more alcoholic drinks per week is associated with brain lesions known as hyaline arteriolosclerosis, which can impair memory and thinking. These lesions are signs of damaged blood vessels that restrict blood flow and gradually harm brain tissue.

Dad’s Alzheimer’s May Raise Tau Levels in Your Brain

New research reveals that people with a father who had Alzheimer’s may be more vulnerable to the spread of tau protein in the brain, a hallmark of the disease. The study followed 243 individuals with a family history of Alzheimer’s over nearly seven years and found that those with affected fathers, especially women, showed greater tau buildup.

Changes in Sleep Patterns Could Predict Dementia Risk

A new study finds that women in their 80s who develop increasing daytime sleepiness over five years are twice as likely to develop dementia. Researchers tracked 733 women without cognitive impairment, using wrist devices to monitor sleep and circadian rhythms.

Physical Activity Lowers Brain Disease Risk

A large study found that people who engage in moderate to vigorous physical activity are significantly less likely to develop dementia, stroke, anxiety, depression, and sleep disorders. Researchers analyzed data from over 73,000 individuals using wearable devices to track their activity levels, providing objective measurements of movement and sedentary behavior.

Family History of Mental Illness Increases Aggression Risk in CTE

A new study reveals that individuals with chronic traumatic encephalopathy (CTE) and a family history of mental illness have a heightened risk of aggression during adulthood, particularly between ages 40 and 59. Researchers analyzed data from 845 men with histories of head injuries, finding that those with both CTE and a family history of mental illness displayed significantly more aggressive behaviors than those with only one risk factor.

LGBTQ+ Community Faces Elevated Dementia and Depression Risks

A new study suggests that LGBTQ+ individuals may face a higher risk of adverse brain health outcomes, including dementia and late-life depression, than their cisgender and straight counterparts. Researchers analyzed data from 393,041 participants and found that LGBTQ+ people were 15% more likely to develop conditions like stroke, depression, or dementia.

Cadmium Exposure Linked to Memory Issues

A recent study explored the link between cadmium exposure and cognitive decline, finding that higher cadmium levels may be associated with thinking and memory problems in white people. The study followed 2,172 people over 10 years, with results showing no association overall but revealing a possible link when analyzing Black and white participants separately.

Lower Dementia Risk Than Previously Thought in Parkinson’s

A new study suggests that the risk of developing dementia in Parkinson’s disease patients may be lower or occur later than previously reported. Researchers analyzed data from two large studies, finding a 9% risk of dementia within 10 years for newly diagnosed patients and a 27% risk for those diagnosed for an average of six years. Factors increasing dementia risk included older age at diagnosis, being male, and lower education levels.

Predicting Cognitive Decline in Early Alzheimer’s

A new study predicts cognitive decline rates in people with early Alzheimer's and explores how new drugs may slow this process. Researchers found that prediction models can estimate the rate of decline but with some uncertainty. These models could eventually help answer practical questions about quality of life for patients. The findings highlight the potential of new treatments to delay cognitive impairment.
