Depression Across Life Linked to Greater Dementia Risk

A comprehensive new analysis reveals that depression significantly increases the risk of developing dementia, whether it begins in midlife or later in life. Researchers reviewed and re-analyzed data from dozens of studies to clarify when depression most strongly affects dementia risk.

Dementia Diagnoses Decline, But More Are Living Longer With the Disease

A new study of over 25 million Medicare recipients found that while dementia incidence in the U.S. is declining, more older adults are living longer with the condition. From 2015 to 2021, new diagnoses dropped from 3.5% to 2.8%, yet prevalence increased to nearly 12%.

Midlife Cortisol Levels Linked to Alzheimer’s Risk

A new study finds that elevated cortisol levels in midlife are linked to increased brain amyloid deposition—a key marker of Alzheimer’s disease—specifically in post-menopausal women. Researchers tracked 305 cognitively healthy individuals over 15 years and discovered that high cortisol predicted amyloid buildup later in life, but only among women who had gone through menopause.

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.

Why Nostalgic Songs Spark the Brain’s Memory and Reward System

Listening to nostalgic music activates key brain regions tied to memory and emotion, according to a new brain imaging study. Researchers found that songs linked to personal memories engage both the default mode network and the brain's reward circuitry.

Digital Tech May Reduce Dementia Risk

Contrary to fears of "digital dementia," new research finds that using digital technology is linked to a reduced risk of cognitive decline in older adults. A large-scale meta-analysis of over 400,000 participants revealed that digital engagement correlates with a 58% lower risk of cognitive impairment.

Mini-Brain Models Reveal a New Dementia-Linked Protein Pathway

Scientists have discovered a new protein pathway involved in neurodegeneration by studying “mini-brain” organoids made from patients with frontotemporal lobar degeneration (FTLD). They found that the protein GRAMD1B plays a crucial role in managing cholesterol and lipid balance within neurons—processes closely linked to Alzheimer’s and FTLD.

Eye Clues May Reveal Early Dementia Risk

A new study has found that blood vessels in the retina may hold early clues about a person’s risk of developing dementia. Researchers observed that narrower arterioles, wider venules, and thinner retinal nerve fiber layers were linked to higher dementia risk around midlife.

Shingles Vaccine Linked to Lower Dementia Risk

A new study has found that getting vaccinated against shingles may reduce the risk of developing dementia by 20% over seven years. This conclusion comes from a natural experiment in Wales, where vaccine eligibility was determined by birthdate.

ADHD May Raise Dementia Risk

A new study finds that adults with ADHD show brain changes similar to those seen in early-stage dementia, including higher iron accumulation and increased neurofilament light chain (NfL) levels in the blood. Using advanced MRI scans and blood tests, researchers identified elevated iron in key brain regions and signs of nerve damage in ADHD patients compared to healthy individuals.
