Air Pollution’s Primary Role in Alzheimer’s Risk Identified

A study of 27 million Americans finds that air pollution directly contributes to Alzheimer’s risk, especially in stroke survivors.

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.

Spreading Brain Waves Drain Neuron Energy

Researchers have, for the first time, tracked how individual neurons lose and recover energy during spreading depolarizations — waves of electrical disturbance linked to brain disorders like stroke. Using genetically modified mice and real-time fluorescent microscopy, the team visualized adenosine triphosphate (ATP) levels in neurons under both healthy and stroke-like conditions.

Microscopic Plastics Found in Arteries Linked to Stroke Symptoms

Micronanoplastics—tiny plastic particles from environmental sources—were found in much higher concentrations in the arteries of people with plaque-related stroke symptoms compared to those with healthy arteries. In a new study, individuals with symptomatic carotid plaque had plastic levels up to 51 times higher than those without plaque.

Oral Bacteria Linked to Stroke Risk

A new study finds that the bacteria Streptococcus anginosus is more abundant in the saliva and gut of people who have had a stroke and is associated with a higher risk of death and major cardiovascular events. Researchers compared 189 stroke patients with 55 non-stroke participants, finding that this bacterium increased stroke risk by 20%.

Sugar Lovers Face Greater Depression and Health Risks

A new study has found that people with a preference for sweet foods face higher risks of depression, diabetes, and vascular issues like stroke. Using data from the UK Biobank, researchers grouped participants into three categories: health-conscious, omnivores, and sweet tooth. They found that the sweet tooth group had poorer blood markers for inflammation and glucose levels, indicating higher risks for metabolic and mental health conditions.

Coffee and Soda Consumption Linked to Higher Stroke Risk

New research has found that frequent consumption of fizzy drinks and fruit juice significantly increases the risk of stroke. The study, which analyzed data from nearly 27,000 participants across 27 countries, showed a 22% increased risk of stroke from drinking fizzy drinks, with the risk rising further with multiple servings per day.

Music Therapy Helps in Brain Rehabilitation

Music-based movement therapy, the Ronnie Gardiner Method, shows promise in aiding rehabilitation for stroke and other brain disorders, according to a review from researchers. This rhythmic and engaging approach, which involves coordinated movements and sounds, has been well-received by participants for its enjoyable and social nature. While the method’s potential benefits for stroke recovery are documented, further studies are needed to validate its effectiveness in other conditions. The Ronnie Gardiner Method may become a valuable addition to traditional neurological rehabilitation.
