Alzheimer's Disease News and Research

RSS

Alzheimer's disease (AD) is an irreversible, progressive brain disease that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks of daily living. In most people with AD, symptoms first appear after age 60. AD is the most common cause of dementia among older people, but it is not a normal part of aging. Dementia refers to a decline in cognitive function that interferes with daily life and activities. AD starts in a region of the brain that affects recent memory, then gradually spreads to other parts of the brain. Although treatment can slow the progression of AD and help manage its symptoms in some people, currently there is no cure for this devastating disease.

Air pollution linked to higher risk of developing Alzheimer's disease

People with greater exposure to air pollution face a higher risk of developing Alzheimer's disease, according to a new study by Yanling Deng of Emory University, U.S.A., and colleagues, published February 17th in the open-access journal PLOS Medicine.

Senescent astrocytes identified as key drivers of Alzheimer's progression

Researchers from the NeuroAD group (Neuropathology of Alzheimer's Disease) within the Department of Cell Biology, Genetics and Physiology at the University of Málaga, also affiliated with IBIMA-BIONAND Platform and CIBERNED, have made a pioneering breakthrough in the fight against this disease by identifying astrocytes as a promising cellular target for the development of future therapies.

Causal gene mapping identifies key drivers of Alzheimer's disease progression

Researchers led by Min Zhang and Dabao Zhang of the University of California, Irvine's Joe C. Wen School of Population & Public Health have created the most detailed maps to date showing how genes causally regulate one another across different types of brain cells affected by Alzheimer's disease.

Early cognitive stimulation preserves memory in Alzheimer’s

A team from the Institute of Neurosciences of the University of Barcelona (UBneuro) has discovered that early and sustained cognitive stimulation can help preserve brain connectivity and memory in Alzheimer's disease, even in advanced stages of the pathology.

FDA-approved anti-seizure drug could help fight Alzheimer's disease

While physicians and scientists have long known Alzheimer's disease involves the buildup of toxic protein fragments in the brain, they have struggled to understand how these harmful fragments are produced.

Neuron lattice structure may guard against neurodegeneration

Brain cells are constantly swallowing material from the fluid that surrounds them - signaling molecules, nutrients, even pieces of their own surfaces - in a process known as endocytosis that is essential for learning, memory and basic neural upkeep.

Lifelong learning associated with lower risk of Alzheimer's disease

Engaging in a variety of intellectually stimulating activities throughout life, such as reading, writing and learning a language, is associated with a lower risk of Alzheimer's disease and slower cognitive decline, according to a new study published on February 11, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Advanced three-dimensional imaging maps vascular amyloid spread

Researchers at Niigata University have used advanced three-dimensional (3D) imaging to reveal how amyloid β (Aβ) deposits spread along blood vessels in the human brain in cerebral amyloid angiopathy (CAA).

'Partial reprogramming' of engram neurons restores memory performance in mice

Age-related memory decline and neurodegenerative diseases like Alzheimer's are often thought of as irreversible.

Choroid plexus enlargement in Long COVID signals cognitive risk

The increased size of, and lesser blood supply to, a key brain structure in patients with Long COVID tracks with known blood markers of Alzheimer's disease and greater levels of dementia, a new study finds.

Low-grade inflammation connects aging, obesity and cognitive impairment

Obesity and older age are strongly associated with low-grade inflammation in the body, a condition that appears closely linked to cognitive decline and dementia.

Cognitive speed training shows potential to delay dementia for two decades

Adults age 65 and older who completed five to six weeks of cognitive speed training - in this case, speed of processing training, which helps people quickly find visual information on a computer screen and handle increasingly complex tasks in a shorter time period - and who had follow-up sessions about one to three years later were less likely to be diagnosed with dementia, including Alzheimer's disease, up to two decades later, according to new findings published today in Alzheimer's & Dementia: Translational Research and Clinical Interventions.
