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.

The diet-Alzheimer’s connection is more complicated than “eat this, avoid that”

A mini-review finds that dietary patterns may influence Alzheimer’s disease through interconnected pathways involving neuroinflammation, insulin resistance, oxidative stress, blood-brain barrier dysfunction, homocysteine, and the gut-brain axis. The authors argue that genetics, sex, age, physical activity, and socioeconomic context may modify these relationships, supporting more individualized approaches to nutrition research and dementia prevention.

Shared protein pathology redefines treatment for multiple neurodegenerative diseases

On the surface, amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD) and limbic-predominant age-related TDP-43 encephalopathy (LATE) might seem like unrelated diseases.

Researchers explore the link between tau levels and depressive symptoms in older people

During typical aging and Alzheimer's disease progression, higher levels of a protein called tau are associated with more depressive symptoms.

FDA clears innovative blood test for earlier Alzheimer's diagnosis

The U.S. Food and Drug Administration (FDA) has cleared for marketing an innovative blood test with underlying technology invented at Washington University School of Medicine in St. Louis for the early diagnosis of Alzheimer's disease.

New review highlights spatial technologies in advanced brain mapping

Understanding how molecular changes shape brain function and disease requires more than measuring genes in bulk tissue.

Lancet review examines possible amyloid-beta transmission through blood transfusions

A review and opinion piece published in The Lancet and led by UCL (University College London) and UCLH researchers discusses the possibility that blood transfusions may inadvertently transmit harmful brain proteins, and whether additional safety measures are warranted as a precaution whilst further research is conducted to better understand these potential risks.

Skull bone marrow contains immune hubs that fight brain cancer

Researchers at Washington University School of Medicine in St. Louis have discovered lymph node-like structures in the skull bone marrow of mice for the first time and demonstrated that they act as rapid first responders against brain cancer before distant lymph nodes get the signal that abnormal cells are present.

Re:Cognition Health launches first dedicated Alzheimer's disease-modifying treatment clinic in Ireland

Re:Cognition Health, the UK's largest independent provider of Alzheimer's disease-modifying treatments, announces the opening of its first Irish clinic in Dublin, marking a major milestone in dementia care for Ireland.

Brain changes detect Alzheimer's seven years before plaques appear

A new study suggests that Alzheimer's disease may be detected by brain imaging more than seven years earlier than previously assumed. Researchers from the Department of Psychology at the University of Oslo led the study, published in Nature Neuroscience.

Leisure-time exercise linked to lower dementia risk

For years, scientists have known that regular physical activity can help lower the risk of dementia. But new USC research suggests that it's not only the amount but also the activity's context - for work or for leisure - that makes a difference.

Youth-associated protein reverses age-related microglial changes in mice

Researchers at The Icahn School of Medicine at Mount Sinai have identified a role for the youth-associated protein TIMP2 in supporting the healthy function of microglia, the brain's resident immune cells.

AI-based "tissue clocks" measure the biological age of human organs

AI-based "tissue clocks" can estimate the biological age of human organs from histological images, researchers at the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences and the Ludwig Boltzmann Institute for Network Medicine (LBI-NetMed) at the University of Vienna showed.

Astrocytes found to directly regulate memory consolidation during sleep

Research has shown that a good night's sleep has many benefits, including memory consolidation. How sleep enables the brain to strengthen memories is still not completely understood, but a new study published in Neuron reveals how astrocytes, brain cells known for supporting neurons and their functions, can directly regulate brain circuits involved in memory consolidation.

Alzheimer's markers show crucial differences across diverse global populations

Established Alzheimer's markers are also detected in blood samples from Nigeria and Tanzania. But other proteins in the blood differ from those seen in a comparable group in Canada.

Later-life estrogen therapy associated with lower risk of developing dementia

Use of hormone therapy later in life was associated with lower risk of developing dementia, according to a study published August 12, 2026, in Neurology, the medical journal of the American Academy of Neurology.

High frequency brain waves help coordinate human working memory

Research from scientists at University of California San Diego School of Medicine and collaborators has shed new light on how the human brain coordinates working memory, the process in which the brain encodes information for immediate or short-term use.
