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.

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.

Restoring brain energy balance reverses advanced Alzheimer’s disease in mouse models

For over a century, Alzheimer's disease (AD) has been considered irreversible. Consequently, research has focused on disease prevention or slowing, rather than recovery.

Simple drug treatments could help older brains cope with memory decline and postoperative recovery

Simple pharmaceutical interventions could help older brains cope with memory impairment and recovery after surgery, new studies in mice suggest.

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.

Targeting CSE enzyme may offer new pathways for Alzheimer’s treatment

Scientists at Johns Hopkins Medicine say results of a new National Institutes of Health-funded study are advancing efforts to exploit a new target for Alzheimer's disease: a protein that manufactures an important gas in the brain.

Researchers explore why Alzheimer's affects men and women differently

More than seven million Americans have Alzheimer's disease, and two-thirds of them are women, according to the Alzheimer's Association. The O'Banion Lab at the Del Monte Institute for Neuroscience at the University of Rochester has long been studying this disease and is looking more closely at the differences between male and female brains.

High-fat cheese and cream consumption links to lower dementia risk over 25 years

Higher intake of high-fat cheese and cream was associated with a lower risk of all-cause dementia over 25 years in a large Swedish cohort, while low-fat dairy showed no association. Associations were strongest for vascular dementia and among APOE ε4 non-carriers, with findings remaining observational.
