Nasal Spray Reverses Brain Aging and Inflammation

A new two-dose nasal spray reverses brain aging by delivering microRNAs directly to the brain. The therapy reduces "neuroinflammation" and restores memory within weeks.

How Your Neighborhood and Nation Shape Your Brain’s Age

A 34-country study reveals that the "exposome"—the combination of pollution, social inequality, and political context—is 15 times more predictive of brain aging than any single risk factor. The research calls for a shift from individual "lifestyle" advice to broad structural policy changes to protect global brain health.

Young Adult Substance Use Affects Memory at 65

Heavy substance use between ages 18 and 30 is linked to poor memory at age 65. While smoking causes direct long-term damage, alcohol and cannabis impact memory by increasing the risk of midlife addiction.

How Brain Networks “Unravel” Over a Lifetime

Mouse brains age in a nearly identical "network" pattern to humans. This shared decline in brain module specialization offers a breakthrough model for testing strategies to slow or reverse cognitive aging.

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.

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.
