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.

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.

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.

Researchers develop mild mitochondrial uncouplers for obesity treatment

Researchers have developed experimental drugs that encourage the mitochondria in our cells to work a little harder and burn more calories. The findings could open the door to new treatments for obesity and improve metabolic health.

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.

Neuronal master switch reshapes brain activity during learning

Memories and learning processes are based on changes in the brain's neuronal connections and, as a result, in signal transmission between neurons.

Menopause hormone therapy not linked to dementia risk in women

A major review of prior research has found no evidence that menopause hormone therapy either increases or decreases dementia risk in post-menopausal women, in a new study led by University College London (UCL) researchers.

Getting a dog for the first time boosts walking and remote social ties

First-time dog owners in Japan showed significant increases in walking activity and non-face-to-face social contact over one year compared with non-dog owners. No significant changes were observed in vigorous activity or face-to-face social contact, highlighting specific behavioral associations rather than broad lifestyle shifts.

Simple blood test maps hidden Alzheimer’s disease changes

This population-based study used plasma pTau217 to estimate how common Alzheimer’s disease neuropathological changes are across age and cognitive status in a Norwegian community cohort. Prevalence rose steeply with age and was strongly associated with APOE ε4 genotype, education level, and kidney function, with implications for future use of blood biomarkers in clinical practice.
