Neighborhood Disadvantage Linked to Alzheimer’s Biomarkers and Inflammation

Living in disadvantaged neighborhoods may increase the risk of Alzheimer’s disease by elevating biomarkers associated with inflammation and neurodegeneration. A long-term study of 334 older adults found higher levels of tau and YKL-40, biomarkers linked to Alzheimer’s and brain inflammation, in people from less advantaged areas.

Brain Age Gap May Predict Cognitive Decline

A new study reveals that the brain age gap—the difference between a brain’s biological age and chronological age—may influence how risk factors like diabetes and high blood pressure affect cognitive function. Using machine learning to analyze brain scans from over 1,400 older adults, researchers found that a greater brain age gap was linked to poorer thinking and memory skills.

Ultra Processed Foods May Accelerate Parkinson’s Brain Changes

A large new study shows that consuming high amounts of ultra processed foods may be linked to early indicators of Parkinson’s disease. Researchers tracked over 42,000 adults for up to 26 years, finding that those eating 11 or more daily servings of ultra processed foods were 2.5 times more likely to show multiple prodromal Parkinson’s symptoms.

Sleep Apnea May Harm Brain Areas Key to Memory

A new study has linked obstructive sleep apnea to brain damage in areas critical for memory, likely due to low oxygen levels during REM sleep. Researchers found that people with lower oxygen saturation during REM had more white matter hyperintensities—signs of small vessel damage—on brain scans.

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.

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.
