          Oral-Gut Bacteria Linked to Dementia Risk in Parkinson’s Disease

          A new study has found that bacteria from the mouth may migrate to the gut and contribute to cognitive decline in people with Parkinson’s disease. Researchers identified harmful microbes and their toxins in the gut of Parkinson’s patients with dementia, suggesting a possible link between oral hygiene, gut health, and neurodegeneration.

          Late-Life Mood Disorders May Foreshadow Alzheimer’s

          Late-life depression and bipolar disorder may be more than psychiatric conditions—they could be early warning signs of neurodegenerative diseases like Alzheimer’s. Using advanced brain imaging and postmortem tissue analysis, researchers found that half of the participants with late-onset mood disorders showed signs of tau accumulation, a key hallmark of neurodegeneration.

          Adopting the MIND Diet May Lower Dementia Risk at Any Age

          A large study suggests that following the MIND diet—rich in leafy greens, berries, nuts, and olive oil—significantly reduces the risk of Alzheimer’s and related dementias. Drawing on data from nearly 93,000 U.S. adults, researchers found the strongest and most consistent protective effects among African American, Latino, and White participants.

          Lowering Blood Pressure May Cut Dementia Risk by Up to 15%

          A massive study in rural China found that intensively lowering blood pressure significantly reduces the risk of dementia and cognitive decline in people with hypertension. Over 48 months, patients who received targeted care saw a 15% reduction in dementia and a 16% drop in cognitive impairment risk.

          Blood Fat Links Found Between Heart Risk and Alzheimer’s

          New research reveals complex relationships between blood lipid levels and the risk of developing Alzheimer’s disease, the most common form of dementia. While small dense LDL cholesterol—linked to heart disease—was associated with increased Alzheimer’s risk, other markers like ApoB48 were linked to reduced risk.

          Common Gene Variant Doubles Dementia Risk, But Only in Men

          New research reveals that men who carry two copies of a common genetic variant in the HFE gene are more than twice as likely to develop dementia, while women with the same variant are not affected. The variant, known as H63D, is linked to haemochromatosis and is present in about 1 in 36 people.

          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.

          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.
