          Smell Test at Home May Sniff Out Early Cognitive Decline

          A new study highlights that olfactory testing could offer a simple, cost-effective way to detect early cognitive impairment from home. Researchers found that older adults with mild cognitive issues performed worse on odor identification and memory tasks than cognitively normal individuals.

          High-Fat Diet Triggers Memory Decline Within Days

          A new study shows that just three days of a high-fat diet can cause memory impairments and brain inflammation in older adults, independent of obesity. Researchers compared young and old rats fed a diet with 60% of calories from fat and found that only the older rats showed cognitive decline.

          SSRIs May Speed Up Cognitive Decline

          A new study based on data from 18,740 dementia patients suggests that antidepressants may accelerate cognitive decline. Researchers found that patients taking antidepressants, particularly SSRIs like escitalopram, citalopram, and sertraline, experienced faster deterioration compared to those not on medication.

          AI Model Predicts Brain Aging Speed to Detect Cognitive Decline Early

          A new AI model can measure how fast a person’s brain is aging using MRI scans, providing a powerful tool for detecting cognitive decline. Unlike previous methods, this model tracks brain aging over time, identifying regions most affected and correlating changes with cognitive function.

          Low-Normal B12 Levels Linked to Slower Brain Processing

          Even when within the normal range, lower levels of vitamin B12 may contribute to cognitive decline, according to a new study. Researchers found that older adults with lower biologically active B12 had slower cognitive processing and more white matter lesions, despite meeting current nutritional requirements.

          Mapping the Link Between Personality and Cognitive Decline

          A new study has identified three psychological profiles that influence brain health, cognitive decline, and dementia risk in aging adults. Profiles with high protective traits, like purpose and openness, show better cognition and brain integrity, while those with low protective traits or high negative traits face accelerated brain atrophy and mental health issues.

          Brain Connectivity Patterns Link Vascular Disease to Cognitive Decline

          Researchers have identified how cerebrovascular disease (CeVD) disrupts brain connectivity, contributing to cognitive decline and neurodegeneration alongside Alzheimer’s disease (AD). By studying brain networks and blood biomarkers in older adults, they discovered distinct but additive effects of CeVD and AD-related markers on cognition and brain atrophy.

          Indoor Temperatures Affect Cognitive Function in Older Adults

          A new study reveals that older adults experience the least attention difficulties when home temperatures remain between 68–75 ˚F (20–24 ˚C). Deviations beyond this range double the risk of attention lapses, highlighting how even current climate conditions may harm cognitive health.

          Structural Sexism Tied to Faster Memory Decline in Older Women

          Women born in states with higher structural sexism experience faster memory decline later in life, with effects equivalent to nine years of cognitive aging. Structural sexism encompasses societal inequities like unequal labor force participation and underrepresentation in government, which create systemic barriers to health. The impact is particularly pronounced among Black women, highlighting the intersection of sexism and racism.

          70 Is the New 60: Age Related Declines Slowing in Older People

          study highlights significant improvements in the physical and mental functioning of older adults in England compared to previous generations. Using data from the English Longitudinal Study of Aging, researchers found that advancements in education, nutrition, sanitation, and medical care have likely contributed to better health outcomes. For instance, a 68-year-old born in 1950 exhibited similar capacities to a 62-year-old born a decade earlier.

          Diets That Reduce Brain Iron May Delay Cognitive Decline

          New research suggests that certain nutrients may lower iron buildup in the brain, a factor linked to cognitive decline in aging. Excess non-heme iron, which accumulates over time, contributes to oxidative stress and can impair memory and executive function.
