Dementia

Dementia is not a specific disease. It is a descriptive term for a collection of symptoms that can be caused by a number of disorders that affect the brain. People with dementia have significantly impaired intellectual functioning that interferes with normal activities and relationships.

What Causes Dementia?

Dementia occurs due to loss of brain function that occurs with certain diseases. It can affect several brain functions such as memory, thinking, language, planning, behavior and judgement. Dementias are usually progressive and worsen with time. They usually are degenerative and non reversible.

Exercise remains essential alongside GLP-1 obesity treatments

As GLP-1 receptor agonists reshape obesity treatment, a new medical perspective published in the Journal of the American Medical Association, or JAMA, underscores a persistent gap in care: integrating exercise into weight management in ways patients can sustain.

Both low and high heart rates linked to stroke risk

A new study presented today at the European Stroke Organisation Conference (ESOC) 2026 suggests that both very low and very high resting heart rates are linked with an increased risk of stroke.

Obesity and Alzheimer’s linked through early metabolic disruptions

By 2030, the population in the United States aged 65 and older is expected to reach 71 million or about 20% of Americans. This growth is likely to increase the burden of age-related diseases, particularly Alzheimer's disease (AD), affecting about 1 in 9 adults over 65.

Ultrasensitive test detects protein clumps to diagnose rare dementia subtype

Dementia affects over 57 million people worldwide, a number expected to nearly double in the next 20 years.

Specific health labels may better motivate reduced alcohol consumption

Although the United States requires a warning label on alcoholic beverages, alcohol-related deaths have risen steadily over the past two decades.

Study links microplastics in arterial plaque to fourfold increase in stroke risk

In a Perspective published today in the inaugural issue of Brain Health (https://doi.org/10.61373/bh026p.0006), an international team of investigators argues that the human microplastic burden has crossed the threshold from environmental concern to brain health emergency. The article appears alongside the launch of Brain Health, a new peer-reviewed journal from Genomic Press dedicated to the science of lifelong brain resilience.

Study reveals gaps in dementia care services across Mississippi counties

Some 80% of Mississippi counties have no adult day service centers, and even counties that do have centers cannot meet the needs of people with dementia and their caregivers, a new University of Mississippi-led study indicates.

AHA calls for lifelong brain health strategy to prevent cognitive decline

The AHA scientific statement calls for a life-course approach to brain health that integrates cognitive, emotional, behavioral, vascular, environmental, inflammatory, sleep, microbiome, and social factors. It highlights how early-life exposures, mental health, pollution, chronic inflammation, poor sleep, gut dysbiosis, and socioeconomic adversity may shape brain resilience and later-life cognitive decline.

PCORI announces new funding for patient-centered clinical effectiveness research

The Patient-Centered Outcomes Research Institute (PCORI) today announced new funding to support patient-centered comparative clinical effectiveness research (CER) across a range of health conditions experienced by Americans, along with projects designed to help bring practice-changing CER results into real-world care settings.

Emergency settings more likely to initiate risky medications for seniors

Initial prescriptions for medications affecting cognition, such as antipsychotics, are disproportionately likelier to come from acute and post-acute settings such as emergency rooms, hospitals and skilled nursing facilities than they are from doctors' offices, new UCLA research suggests.

New scientific statement defines brain health across life

Brain health isn't determined only by genetics or what happens later in life. A growing body of research shows that a range of factors-from mental health and sleep to environment, lifestyle and social conditions-play a powerful role in shaping how the brain functions and ages.

Scientists uncover why brain damage continues after stroke

Every stroke begins with a sudden interruption of blood flow in the brain. But what happens afterward—why neurons continue to lose function and die over the following days—has remained one of the most important unanswered questions in neuroscience.
