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.

Social support plays an important role in health and well-being of older adults

Two recent studies from the University of Eastern Finland show that social support plays an important role in health and well-being in later life. Having access to adequate social support is associated with longevity among older adults, and with better quality of life among home care recipients.

New AI models detect dementia with high accuracy using EEG signals

Researchers at örebro University have developed two new AI models that can analyze the brain's electrical activity and accurately distinguish between healthy individuals and patients with dementia, including Alzheimer's disease.

New imaging method reveals nanodomains inside ALS-linked protein droplets

Inside the cell reside many tiny assembly factories and warehouses that gather together all of the proteins and RNAs-which carry out instructions from our DNA-that a living being needs.

Shared genetic roots between delirium and Alzheimer’s disease

This study reveals genetic and proteomic risk factors for delirium, offering insights into its etiology and potential biomarkers for prediction and prevention.

Head trauma impairs brain waste clearance in professional fighters

The brain's waste-clearing system significantly declines in function with repeated head impacts, according to a new study of cognitively impaired professional boxers and mixed martial arts fighters. The findings will be presented next week at the annual meeting of the Radiological Society of North America.

White matter alterations connect coronary artery disease to cognitive decline

Individuals with coronary artery disease (CAD) - a constricting or blocking of blood vessels feeding the heart - face increased risks of strokes, cognitive impairment and dementia. However, the link between CAD and cognitive function is not fully understood.

Study elucidates how anti-amyloid antibody therapy lecanemab works in Alzheimer's disease

Lecanemab, sold under the name Leqembi, is a monoclonal antibody therapy for Alzheimer's disease that clears toxic amyloid plaques and delays cognitive decline.

Infection-related hospital stays linked to higher risk of developing dementia

A new research paper was published in Volume 17, Issue 10 of Aging-US on October 13, 2025, titled "Hospitalization with infections and risk of Dementia: a systematic review and meta-analysis."

Scientists uncover how brain enzyme OTULIN controls tau expression

Scientists have uncovered a surprising mechanism by which a brain enzyme called OTULIN controls the expression of tau, the protein that forms toxic tangles in Alzheimer's disease.

Neuroscientists detect five broad phases of brain structure in the average human life

Neuroscientists at the University of Cambridge have identified five "major epochs" of brain structure over the course of a human life, as our brains rewire to support different ways of thinking while we grow, mature, and ultimately decline.

Arginine slows amyloid buildup and improves brain outcomes in Alzheimer’s disease models

Arginine reduced amyloid beta aggregation in vitro and in both Drosophila and AppNL-G-F mouse models of Alzheimer’s disease, leading to fewer dense-core plaques and improved behavior. The study provides preclinical evidence that oral arginine may modulate amyloid pathology, although high dosing requirements and model limitations constrain human translation.

Can diet calm early memory problems? Anti-inflammatory Mediterranean eating shows promise

Older women who follow a strongly anti-inflammatory Mediterranean diet report far fewer subjective memory complaints than those who do not. The AnMED pattern outperforms both traditional Mediterranean and MIND diets, showing a clear advantage for protecting early cognitive symptoms.

New discovery could reshape how scientists think about Alzheimer’s treatment

Rutgers neuroscientist Peng Jiang was visiting his hometown of Qianshan, a city in China's Anhui province, when a neighbor came to his parents' house with a story that would stay with him.

Hearing loss emerges as a key early warning sign for Alzheimer disease

Hearing loss also predicts a significantly higher risk of dementia, especially in APOE ε4 carriers, highlighting its value as an early risk marker.

Does coffee truly boost memory and focus or is it all hype?

Coffee’s bioactive compounds, especially caffeine, show potential cognitive, neuroprotective, and neuroplasticity benefits across animal and human studies. However, most findings are observational, mechanisms remain uncertain, and optimal intake is still unclear.

Oral arginine reduces amyloid buildup in Alzheimer’s models

Alzheimer's disease (AD), a progressive neurodegenerative disorder, is one of the leading causes of dementia worldwide, and currently has no definitive cure. Although antibody-based therapies that target amyloid β (Aβ) have recently been developed, their clinical effectiveness remains limited.

Midlife exercise cuts dementia risk by up to 45 percent, new study shows

Higher physical activity in midlife and late life is linked to a substantially lower risk of all-cause and Alzheimer’s dementia. Midlife benefits are strongest for moderate or heavy activity, while late-life activity is protective across all intensity levels.

Clogged brain drains may signal early Alzheimer's risk

"Drains" in the brain, responsible for clearing toxic waste in the organ, tend to get clogged up in people who show signs of developing Alzheimer's disease, a study by researchers from Nanyang Technological University, Singapore (NTU Singapore) has discovered.

Study links obesity severity to escalating cardiometabolic and renal disease burden

Obesity severity is incrementally associated with a broad range of cardiometabolic and renal disease burden, as discovered by researchers at Pennington Biomedical Research Center. Recently published in Obesity, the paper "Association of Obesity Severity with Cardiometabolic and Renal Disease Burden in the United States," explored the relationship through a cross-sectional study of data from the U.S. Behavioral Risk Factor Surveillance System survey.
