Dementia

Dementia is not a specific disease. It is a descriptive term for a collection of symptoms that can be caused by a number of disorders that affect the brain. People with dementia have significantly impaired intellectual functioning that interferes with normal activities and relationships.

What Causes Dementia?

Dementia occurs due to loss of brain function that occurs with certain diseases. It can affect several brain functions such as memory, thinking, language, planning, behavior and judgement. Dementias are usually progressive and worsen with time. They usually are degenerative and non reversible.

MIT researchers map dynamic fuzzy coat surrounding tau protein fibrils

One of the hallmarks of Alzheimer's disease is the clumping of proteins called Tau, which form tangled fibrils in the brain. The more severe the clumping, the more advanced the disease is.

Post-meal blood sugar spikes linked to increased Alzheimer's risk

A new study led by researchers from the University of Liverpool has found that spikes in blood sugar after meals may increase the risk of Alzheimer's disease.

Vaccines are helping older people more than we knew

Let's be clear: The primary reason to be vaccinated against shingles is that two shots provide at least 90% protection against a painful, blistering disease that a third of Americans will suffer in their lifetimes, one that can cause lingering nerve pain and other nasty long-term consequences.

New European initiative aims to transform real world Alzheimer’s disease care

Today, the ACCESS-AD consortium is announcing the launch of a transformative European initiative that will accelerate the implementation of scientific innovations for Alzheimer's disease (AD) management in real-world health systems.

Study explores how biological and environmental systems regulate body weight

Pennington Biomedical researchers recently investigated the systems of the body that regulate weight, exploring whether our bodies defend an established weight target or if our bodies operate within a broader range of tolerance before biological mechanisms are activated.

Study sheds new light on how structural brain changes are tied to memory decline in aging

A landmark international study that pooled brain scans and memory tests from thousands of adults has shed new light on how structural brain changes are tied to memory decline as people age.

Research finds persistent prescribing of risky medications to older adults with dementia

Despite years of clinical guidelines warning against the practice, one in four Medicare beneficiaries with dementia is prescribed brain-altering medications linked to falls, confusion, and hospitalization, according to new research to be published January 12 in the peer-reviewed journal JAMA.

Sex-based differences and role of BMP signaling in neurogenesis in Alzheimer's mice models

Alzheimer's disease (AD) is a serious neurodegenerative disease largely affecting older adults. Apart from age, it also shows sex-based differences, with women being more at risk. However, the origin of these differences remains unknown.

APOE gene: A major driver in Alzheimer's disease

Potentially more than 90% of Alzheimer's disease cases would not occur without the contribution of a single gene (APOE), according to a new analysis led by UCL researchers.

In Lodge Grass, Montana, a Crow community works to rebuild from meth’s destruction

Brothers Lonny and Teyon Fritzler walked amid the tall grass and cottonwood trees surrounding their boarded-up childhood home near the Little Bighorn River and daydreamed about ways to rebuild.

AI trained on sleep data predicts future disease and mortality years in advance

The SleepFM model reveals how sleep analysis can predict disease risk, offering insights into sleep's role as a vital health indicator for early intervention.

Homeless shelters for seniors pop up, catering to older adults’ medical needs

Just outside Salt Lake City sits an old, two-story, brick hotel. It's been given new life as a homeless shelter for seniors. The Medically Vulnerable People shelter — or MVP shelter, as it's known — is for people 62 and older or for younger adults with chronic health issues.

Finger-prick blood test shows promise for detecting Alzheimer’s disease biology

Finger-prick dried blood sampling can accurately measure key Alzheimer’s disease biomarkers, including p-tau217, GFAP, and NfL, showing strong concordance with venous plasma and meaningful associations with CSF pathology. While analytical limitations remain, this minimally invasive approach shows promise as a scalable research and screening tool within biomarker-based diagnostic pathways.

Two isoforms of a cellular energy sensor play distinct, opposing roles in Alzheimer's disease

A comprehensive mini-review published today after peer review in Brain Medicine by Dr. Tao Ma and colleagues at Wake Forest University School of Medicine synthesizes emerging evidence that two isoforms of a critical cellular energy sensor play distinct, and sometimes opposing, roles in Alzheimer's disease.

AI model can predict a person's disease risk using sleep data

A poor night's sleep portends a bleary-eyed next day, but it could also hint at diseases that will strike years down the road.

Finger-prick blood tests enable remote detection of Alzheimer’s biomarkers

A groundbreaking international study has demonstrated that Alzheimer's disease biomarkers can be accurately detected using simple finger-prick blood samples that can be collected at home and mailed to laboratories without refrigeration or prior processing.

New guidelines aim to standardize diagnosis of canine dementia

An international working group of canine cognition experts has released a set of guidelines for veterinarians to use in diagnosing and monitoring canine cognitive dysfunction syndrome (CCDS), or canine dementia.

Common blood signals explain why chronic diseases cluster as we age

This population-based study shows that shared and pattern-specific blood biomarkers reflect biological vulnerability underlying multimorbidity and the pace at which chronic diseases accumulate in older adults. Metabolic and systemic stress markers such as GDF15, HbA1c, cystatin C, and insulin consistently tracked higher disease burden and faster accumulation, with findings replicated across cohorts.

Weaker and fragmented circadian rhythms linked to higher dementia risk

Circadian rhythms that are weaker and more fragmented are linked to an increased risk of dementia, according to a new study published on December 29, 2025, in Neurology®, the medical journal of the American Academy of Neurology.
