Stroke Impact Determines Future Dementia Risk

A 30-year study of 42,000 adults shows that stroke severity is a primary driver of post-stroke dementia and accelerated brain aging.

The Natural “Biological Clock” of Stroke Recovery

High-intensity therapy in the first two weeks after a stroke does not improve hand recovery more than standard care. Natural biological repair seems to dominate the early phase of healing.

Stroke Survivors’ Brains Rejuvenate to Compensate for Injury

Can a stroke make part of your brain younger? New research using deep learning reveals that undamaged brain regions reorganize and show "youthful" structural patterns to compensate for severe stroke damage.

Brain’s “On-Switch” for Imagination Found

Imagination's "Off" switch. Scientists identify a specific brain node that, when damaged or disconnected, causes the "mind's eye" to go dark.

Stroke Weakens How the Brain Integrates Speech Sounds

A new study comparing stroke survivors with healthy adults reveals that post-stroke language disorders stem not from slower hearing but from weaker integration of speech sounds. While patients detected sounds as quickly as controls, their brains processed speech features with far less strength, especially when words were unclear.

Over 99% of Heart Attacks Linked to At Least One Known Risk Factor

A massive international study shows that nearly all heart attacks, strokes, and cases of heart failure occur in people with at least one known cardiovascular risk factor. More than 9 million South Korean adults and thousands of U.S. adults were tracked, revealing that over 99% had nonoptimal blood pressure, cholesterol, blood sugar, or tobacco use years before their first event.

DMT Shows Promise in Protecting the Brain After Stroke

New research shows that DMT, a natural psychoactive compound found in plants and the human brain, can protect against stroke damage in animal and cell models. Treatment with DMT reduced infarct size, brain swelling, and inflammation, while also repairing blood-brain barrier function.

Common Sweetener May Raise Stroke Risk by Altering Brain Cells

A common sugar substitute, erythritol, widely used in “sugar-free” and low-carb products, may increase stroke risk by damaging brain blood vessel cells. A new study found that erythritol exposure reduced nitric oxide, increased vessel constrictors, impaired clot-busting abilities, and boosted free radical production in these cells.

Chronic Stress Quietly Raises Your Stroke Risk

Chronic stress is increasingly recognized as a contributor to stroke risk by intensifying conditions like high blood pressure, inflammation, and unhealthy lifestyle habits. While stress isn't as easily measured as cholesterol or blood pressure, long-term exposure to it can set the stage for vascular damage and increase both ischemic and, less commonly, hemorrhagic stroke risk.
