Attention and Focus Abilities Peak Between Ages 27 and 36

Researchers analyzed 139 neuroimaging studies spanning ages 5 to 85 to map the brain’s activity in cognitive control. They found an inverted U-shaped lifespan trajectory, with brain activity rising through adolescence, peaking between ages 27 and 36, and then gradually declining.

This shows a brain with the cerebral cortex highlighted.

Touch-Processing Brain Layers Age Differently

Researchers found that the touch-processing region of the brain ages in a layered pattern, with some layers staying resilient while others thin over time. High-resolution MRI scans revealed that the middle and upper layers of the primary somatosensory cortex often remain stable or thicken with age, likely due to frequent sensory stimulation.

Natural Compound Combo Restores Aging Brain Cells

Scientists have identified a natural compound combination that reverses aging-related brain cell decline and removes harmful Alzheimer’s-linked proteins. The treatment, combining nicotinamide (vitamin B3) and the green tea antioxidant epigallocatechin gallate, restores guanosine triphosphate (GTP) levels—critical for neuronal energy and protein cleanup.

COVID Stress May Have Aged Brains Faster

Living through the Covid-19 pandemic may have accelerated brain ageing, even in people who were never infected, a new study finds. Brain scans of nearly 1,000 adults showed older, male, and disadvantaged individuals were most affected.

How Fast Your Brain Ages Could Determine Your Future Health

A new study reveals that our organs age at different speeds, and those differences can predict future disease risk and even life expectancy. Using blood-based protein signatures from over 44,000 participants, researchers developed an algorithm to estimate the biological age of 11 organ systems.

Brain Scan Predicts Dementia Risk and Aging Speed in Midlife

A new tool developed by researchers can estimate how fast someone is aging by analyzing a single MRI brain scan, predicting chronic disease risk and dementia years before symptoms appear. Unlike traditional “aging clocks,” this model was trained using longitudinal data from the same individuals, eliminating generational biases.

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.

Healthy Habits May Offset Brain Aging Linked to Shorter Telomeres

New research shows that healthy lifestyle choices can reduce the risk of stroke, dementia, and depression—even in people with biologically shortened telomeres. Telomeres are protective DNA caps that naturally shrink with age and environmental stress, increasing vulnerability to age-related brain diseases.

Facial Stimulation Clears Brain Waste and Boosts Aging Minds

Researchers have discovered a safe, non-invasive way to enhance the brain’s waste clearance system by mechanically stimulating lymphatic vessels just beneath the facial skin. This gentle technique significantly improves cerebrospinal fluid (CSF) drainage—a critical function that declines with age and contributes to cognitive disorders like Alzheimer’s.

Aging Brain More Vulnerable to Even Mild Oxygen Deprivation

New research shows that even mild, prolonged exposure to low oxygen levels can significantly disrupt the blood-brain barrier (BBB) in aging brains. Using mice aged 2 to 23 months, scientists found that older mice experienced 4–6 times more BBB breakdown than younger mice under similar hypoxic conditions.

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.

Decoding Brain Aging: A 10-Year Study Opens Data for Discovery

A decade-long brain health study has released its full dataset, offering rare longitudinal insights into how cognition and brain structure change across adulthood. The Dallas Lifespan Brain Study tracked nearly 500 individuals from age 21 to 89 over three timepoints using brain scans, cognitive tests, and health surveys.
