Superagers’ Brains Keep Growing New Neurons

The secret to a 20-year-old’s memory in an 80-year-old’s body. Scientists discover that superagers have "neuronally fertile" brains that never stop growing.

Moderate Cannabis Use May Protect the Aging Brain

A massive study of over 26,000 middle aged and older adults reveals that those who use cannabis in moderation have larger brain volumes and sharper cognitive skills than non-users.

Social Isolation Directly Speeds Up Cognitive Decline

Social isolation has a direct causal impact on how quickly cognitive function declines in later life, independent of whether someone feels lonely. By analyzing more than 137,000 cognitive tests from over 30,000 older adults, the study found that reduced social contact consistently predicted faster decline across every demographic group.

PTSD Linked to Accelerated Brain Aging

A new study using advanced deep-learning brain age estimation shows that World Trade Center responders with PTSD exhibit signs of accelerated brain aging. Using BrainAgeNeXt, a model trained on more than 11,000 MRI scans, researchers found that responders with PTSD had “older” appearing brains than those without the disorder, especially among individuals with longer exposure at Ground Zero.

Creativity Key to Slowing Brain Aging

Regular creative activity is linked to a younger-looking brain and slower brain aging, according to a large international brain-imaging analysis. People who regularly danced, made music, created visual art, or played strategy-based video games showed brain patterns associated with delayed aging.

Your Brain Quietly Rewires Itself at 9, 32, 66 and 83

Researchers identified five major phases of human brain wiring that unfold from birth to old age, marked by four major turning points at ages 9, 32, 66, and 83. Childhood and adolescence are periods of rapid reorganization, while adulthood brings a long plateau of structural stability.

Young Adults With Obesity Show Early Signs of Brain Stress

New research shows that young adults with obesity already display biological patterns associated with liver stress, chronic inflammation, and early neural injury—changes typically seen in older adults with cognitive impairment. Participants with obesity also had unusually low blood choline levels, a nutrient critical for liver function, inflammation control, and long-term brain health.

Speaking Multiple Languages May Slow Down Biological Aging

A large-scale study of more than 86,000 Europeans found that speaking multiple languages may help slow biological and cognitive aging. Using artificial intelligence to assess “biobehavioral age gaps,” researchers discovered that multilingual individuals were over twice as likely to show signs of healthy aging compared to monolinguals.

Infant Brain Gene Regulator May Predispose Adults to Dementia

A new study reveals that the brain’s vulnerability to disorders like multiple sclerosis and dementia may begin in early life. Researchers identified a developmental “switch” in astrocytes, the brain’s support cells, governed by the NR3C1 gene.

Healthy Habits Can Make Your Brain Up to 8 Years Younger

A new study shows that brain health is closely tied to lifestyle choices, with positive habits making brains appear years younger than their chronological age. Researchers followed adults, many with chronic pain, and found that optimism, restorative sleep, social connections, and stress management strongly protected against accelerated brain aging.

Dementia Prevention Must Begin in Childhood, Not Just Midlife

A large international study shows that the accumulation of social hardships across life—known as the social exposome—has lasting effects on the brain. Adverse exposures, including low education, food insecurity, and limited healthcare, were linked to cognitive decline, mental health issues, and altered brain structure and function.

Green Mediterranean Diet Slows Brain Aging

A large-scale dietary trial has shown that a green-Mediterranean diet can slow brain aging by altering key blood proteins linked to neurodegeneration. Using MRI scans and proteomic profiling, researchers tracked nearly 300 participants over 18 months and found that diet significantly shaped the brain age gap.
