Alzheimer's & Dementia

Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills. Alzheimer’s is the most common cause of dementia among older adults. Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities to such an extent that it interferes with a person’s daily life and activities.

Alzheimer’s Disease | Definition, Causes, Diagnosis & Treatment

Alzheimer’s Disease (AD) is the most common form of dementia worldwide (60-70% of all dementia cases) and is a progressive neurodegenerative disorder.

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.

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.

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.
