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.

New immuno-infrared sensor aids in early diagnosis of Alzheimer’s and Parkinson’s disease

An early start to treatment is crucial to successful therapy. A new sensor is helping with early detection.

New study shows how exercise hormone reduces multiple sclerosis symptoms

A new study offers clues as to why exercise can improve neurological symptoms in people with multiple sclerosis (MS).

Uneven grey matter loss serves as a powerful new biomarker for early neurodegeneration

Universitat Oberta de Catalunya Alzheimer's disease begins to weave a web in the brain and remodel neuronal tissue 15 to 20 years before the first symptoms appear. From the time this happens, however, until the disease is diagnosed and, later, enters an advanced phase, it progresses along a continuum of changes to the brain.

Key neural circuit helps the brain “change gears”

Most people have experienced the feeling: switching from one task to another, only to find the brain momentarily stuck in the old mode of thinking. Sometimes, even after realizing a strategy no longer works, the mind keeps returning to it anyway.

Smoking cessation may reduce dementia risk for people who avoid major weight gain

Quitting smoking may be associated with a lowered risk of dementia, especially for people who avoid major weight gain after quitting, according to a study published May 20, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Poor sleep may flag early Alzheimer’s risk in genetically vulnerable older women

Poorer subjective sleep quality was linked to worse visual memory and greater limbic tau burden in older women with higher genetic risk for Alzheimer’s disease. The findings suggest sleep complaints may help identify women at elevated risk for early AD-related brain and cognitive changes, but larger longitudinal studies are needed.

New AI framework maps systemic obesity damage at cellular resolution

Researchers at Helmholtz Munich, the Ludwig Maximilians University Munich (LMU) and collaborating institutions have developed an artificial intelligence (AI) framework that maps disease-related changes throughout the entire mouse body at cellular resolution.

Early electronic advance directives reduce burdensome end-of-life care

Advance directives document patient preferences for future care, including end-of-life. An analysis in the Journal of the American Geriatrics Society found that older patients with an advance directive that had been uploaded into the electronic health record at least six months before death were 25% less likely to experience potentially burdensome end-of-life care (19.9% versus 26.8%) and 31% less likely to have died in the hospital (23.2% versus 32.1%).

Women may face greater cognitive impact from dementia risk factors

Researchers from the University of California San Diego School of Medicine found that women not only experience a higher burden of certain modifiable dementia risk factors, but also appear more vulnerable to their effects on cognitive function.

Facial micromovements may help doctors measure pain more accurately

Researchers at Rutgers University-New Brunswick are working to measure pain more accurately beyond the single, subjective question patients are often asked: "On a scale of 1 to 10, how bad is your pain?"

Pennington and Vanderbilt launch major study on childhood obesity treatment

Pennington Biomedical Research Center, in collaboration with Vanderbilt University Medical Center, has launched a research study, the COACH trial, to test different ways to help children and their families improve their health through lifestyle changes delivered by primary care clinics in communities in Louisiana and Tennessee.

Popular analysis technique hides patient variability in Alzheimer's drug trials

A statistical approach being used to support a new class of Alzheimer's drugs may lead to overstated claims about how the drugs work, according to a new study led by researchers at the Brown University School of Public Health.

Discovery of memory switch in the brain opens new avenues for dementia therapies

"Why do patients with dementia or cognitive decline remain stuck in past memories?" KAIST researchers have identified, for the first time in the world, the existence of a "neural switch" in the brain that selectively retrieves the most recent memories.
