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.

Latest Alzheimer's & Dementia News and Research

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.

25 Nov 2025

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.

25 Nov 2025

New analysis shows one in two people in the U.S. live with neurological conditions

One in two people in the United States, just over half of the population, is affected by a neurological disease or disorder, according to a new systematic analysis by the American Academy of Neurology and the Institute for Health Metrics and Evaluation published on November 24, 2025, in the journal JAMA Neurology.

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.

24 Nov 2025

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.

23 Nov 2025

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.

Changes in brain fats play a key role in Alzheimer's development and progression

More than a century ago, Alois Alzheimer noted unusual changes in brain fats, which he described as "lipoid granules," along with the buildup of amyloid-beta (amyloid) plaques and tau protein tangles.

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.

Evaluating whether LIT supplementation slows cognitive decline in Alzheimer’s patients

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline such as memory loss and behavioral disturbances that severely impair quality of life. Despite decades of research, effective disease-modifying therapies remain elusive, underscoring the urgent need for novel neuroprotective strategies.
