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.

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.

Engineered CAR-T cells reduce Alzheimer’s plaques in mice

Chimeric antigen receptor (CAR) T cell therapy, a type of immunotherapy that leverages the immune system to combat diseases, is a powerful treatment option for certain cancers.

Brain immune cells regulate new neuron formation in adults

Breakthrough research from the University of Cincinnati College of Medicine is revealing how immune cells in the adult brain can regulate the generation of new neurons.

AI-powered tool automatically segments human brainstem white matter bundles

Small and dense but filled with vitally important neural fibers, the brainstem has been hard for brain imaging technologies to dissect.

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.

Inhibiting PTP1B protein improves memory in Alzheimer’s disease models

Alzheimer's disease is often measured in statistics: millions affected worldwide, cases rising sharply, costs climbing into the trillions.

Breastfeeding and pregnancy linked to improved postmenopausal cognition

Female brains have historically evolved to adapt to pregnancy, undergoing structural and functional changes.

Most commercially insured patients live with chronic conditions

The majority (57.5 percent) of commercially insured patients had at least one chronic condition in 2024. The average allowed amount for a patient with no chronic conditions was $1,590, while the average allowed amount for a patient with one chronic condition was nearly double ($3,039).

Aging brains struggle to recycle synaptic proteins

As we age, we begin to lose the connections that wire up our brains-and neuroscientists aren't sure why.

Researchers uncover a new cellular process linked to healthy aging

Improvements in public health have allowed humankind to survive to older ages than ever before, but, for many people, these added golden years are not spent in good health.

Distinct tau chemical signatures redefine diagnosis across neurodegenerative diseases

Tau protein aggregation is a shared feature in over 20 neurodegenerative diseases (collectively referred to as "tauopathies"). New research led by Boston Children's Hospital challenges the current "one-size-fits-all" approach to diagnosing and treating these tauopathies.

Hippocampus reorganizes memories to anticipate future outcomes, study finds

A preclinical study published in Nature has found evidence that the hippocampus, the brain region that stores memory, also reorganizes memories to anticipate future outcomes.

Research uncovers why certain brain cells are more resilient to tau protein buildup

New research by UCLA Health and UC San Francisco has uncovered why certain brain cells are more resilient than others to the buildup of a toxic protein that is a hallmark of Alzheimer's disease and related dementias, potentially leading to new targets for therapies or treatments.

Study uncovers how the brain's 'memory replay' process is impaired in Alzheimer's disease

Memory dysfunction in Alzheimer's disease may be linked to impairment in how the brain replays our recent experiences while we are resting, according to a new study in mice by University College London (UCL) scientists.

People with cerebral amyloid angiopathy more likely to develop dementia

Cerebral amyloid angiopathy (CAA) is a condition where protein (called amyloid) builds up in the brain, making blood vessels weak.

Older adults' driving habits may provide early warning signs of cognitive decline or dementia

Older adults' driving habits revealed clues about their brain health and may provide early warning signs of cognitive decline or dementia, according to a preliminary study to be presented at the American Stroke Association's International Stroke Conference 2026.
