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

High-resolution study maps molecular differences across six human cortical regions

A new analysis of individual brain cells across several human brain regions reveals subtle but widespread differences in gene activity between male and female brains. This may help explain why some psychiatric and neurological disorders appear to affect the biological sexes differently, researchers report.

How the immune system may influence Alzheimer’s, Parkinson’s, and related diseases

This review argues that neurodegeneration is shaped not only by toxic protein buildup but also by immune signaling, with microglia and T cells able to either protect the brain or worsen damage depending on context. It also highlights aging, head injury, and viral infection as major forces that reshape CNS immunity and may influence disease progression and future treatment strategies.

Researchers discover a molecular signature to flag dysfunctional aging cells

UCLA researchers have identified a rogue population of immune cells that quietly accumulates in aging tissues and in the livers of people with fatty liver disease. Clearing these cells, they found, dramatically reduced inflammation and reversed liver damage in mice - even while the animals remained on an unhealthy diet.

Clearing amyloid beta shows no significant impact on dementia severity

Drugs that target amyloid beta proteins in the brain likely have no clinically meaningful positive effects, while increasing the risk of bleeding and swelling in the brain, a new Cochrane review has found.

Older adults show high willingness for Alzheimer’s blood tests

Northwestern University psychologist Andrea Russell sees older adults with early cognitive impairment riddled with anxiety. Some worry a missed word or forgotten appointment could signal Alzheimer's disease.

Study explains failure of cellular cleanup in neurodegenerative diseases

Inside every cell, a cleanup operation runs around the clock. Proteins are constantly damaged by wear and tear. Some can be repaired, while others must be dismantled and recycled.

New grant funds AI search for genetic targets to treat Alzheimer's

With a new $6.2 million, five-year grant from the National Institute on Aging, researchers at Case Western Reserve University will use artificial intelligence (AI) and machine learning to identify possible genetic targets to treat Alzheimer's disease.

Brief intense workouts offer significant health benefits

At this time of year, many people make an extra effort to establish good exercise routines. We know that exercise is good for our health, but it can still be difficult to get started and maintain good habits.

Feeling lonely impacts memory without accelerating mental decline

Loneliness affects the memory of older adults but does not speed up mental decline over time, suggests data from a major European study tracking more than 10,000 people over seven years.

Alzheimer's risk gene APOE4 impacts bone health in females

Scientists at the Buck Institute for Research on Aging, along with collaborators at UC San Francisco, have discovered that APOE4, the most common genetic risk factor for Alzheimer's disease, causes bone quality deficits specifically in female mice, through a mechanism that is invisible to standard imaging and can emerge as early as midlife.

Supportive neighborhoods linked to slower cognitive decline in older immigrants

Older Chinese immigrants living in neighborhoods with greater access to community amenities, services and supportive infrastructure experienced slower cognitive decline over time, according to Rutgers Health researchers.

Vaping may raise cognitive impairment risk in young adults, study finds

A cross-sectional study of 232 young adults in Bangkok found that e-cigarette users were more likely than non-smokers to screen as at risk for cognitive impairment on the MoCA, while no significant differences were seen for ADHD symptom tendency or emotional intelligence. The authors say the findings raise neurocognitive concerns but do not prove causation, and they call for longitudinal research to clarify whether vaping contributes to later cognitive decline.

Eardrum perforations and cholesteatoma linked to higher odds of dementia

A new study published in Otolaryngology–Head and Neck Surgery, the official peer-reviewed publication of the American Academy of Otolaryngology–Head and Neck Surgery Foundation (AAO-HNSF), finds that two common and treatable causes of conductive hearing loss-eardrum perforations and cholesteatoma, a type of abnormal skin growth in the middle ear-are associated with higher odds of dementia.

Research aims to identify blood biomarkers for predicting Alzheimer's disease

With a NOK 40 million (approx. €3.5 million) grant, Professor Srdjan Djurovic at the University of Oslo aims to identify early blood-based biomarkers that can predict who is at increased risk of developing Alzheimer's disease.

Moving more, sitting less, and sleeping well may lower dementia risk

Findings suggest that regular physical activity and adequate sleep may lower dementia risk, emphasizing the need for evidence-based lifestyle guidelines.

Higher optimism may lower dementia risk in older adults

Higher optimism in adults aged 70 and older was associated with a lower risk of developing dementia over up to 14 years of follow-up in the Health and Retirement Study. The association remained after adjustment for demographic factors, depression, health conditions, smoking, and physical activity, although the study was observational and cannot prove causation.

Study reveals lung-brain link between smoking and neurodegeneration

The correlation between smoking and neurodegeneration is well-documented, with one study from 2011 finding heavy smoking in midlife was associated with a greater than 100% increase in risk of dementia, Alzheimer's and vascular dementia more than two decades later.
