Heart Attacks Release Toxin That Damages Brain Function

Why do heart attacks so frequently trigger severe depression, anxiety, and accelerated dementia? A new study maps the "heart-brain axis," proving that dying cardiac tissue releases a toxic metabolic byproduct called methylglyoxal (MG).

Low-Level Air Pollution Linked to Cognitive Decline, Brain Damage

Can breathing everyday air quietly damage your brain structure decades before cognitive symptoms appear? A new study reveals that long-term exposure to low levels of air pollution is directly linked to worse memory, comprehension, and processing speed.

This shows the outline of two people and brains.

Reducing Visceral Fat Protects the Brain for Decades

A landmark 16-year MRI study identified cumulative abdominal fat as a specific, modifiable risk factor for brain atrophy. The findings demonstrate that sustained reductions in visceral fat, mediated by better glucose control, are essential for preserving hippocampal volume and cognitive function in late midlife, independent of total weight loss.
