Low Income, Vision Loss, and Isolation Drive Dementia Risk

A new study reveals that people with lower incomes and those from historically underrepresented racial and ethnic groups carry a higher burden of modifiable dementia risk factors. Vision loss and social isolation were among the most significant contributors for those living below the poverty line, suggesting that better access to healthcare and community support could have major protective effects.

Poor Oral Health Linked to Brain Damage Markers

A new study finds that older adults with gum disease are more likely to show signs of white matter damage in the brain — a change tied to memory decline, balance issues, and higher stroke risk. MRI scans revealed that participants with gum disease had significantly more white matter hyperintensities than those without, even after accounting for age and other health factors.

Skin-to-Skin Contact Boosts Brain Development

Very preterm infants who received more skin-to-skin contact during their hospital stay showed stronger development in brain regions tied to stress and emotional regulation. Brain scans revealed that longer skin-to-skin sessions were linked to changes in white matter pathways that support attention, memory, and emotional health.

Artificial Sweeteners Tied to Faster Cognitive Decline

A large study of nearly 13,000 adults found that consuming high levels of certain artificial sweeteners is linked to faster declines in memory and thinking over eight years. The effect was particularly strong in people with diabetes and those under 60. Some sweeteners, like aspartame and saccharin, were strongly associated with decline, while tagatose was not.

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.
