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.

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.

AI analysis maps a century of global aging research

A new research paper was published in Volume 17, Issue 11 of Aging-US on November 25, 2025, titled "A natural language processing–driven map of the aging research landscape."

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.

Research highlights a potential therapeutic strategy for vascular dementia

A possible new treatment for impaired brain blood flow and related dementias is on the horizon.

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.

Study finds Brain Care Score as a strong predictor of stroke across racial groups

A new study from Mass General Brigham found the Brain Care Score (BCS) is a strong predictor of stroke across different racial groups in the U.S.

Experimental drug targets early toxic amyloid to slow Alzheimer’s disease

An experimental drug developed at Northwestern University has demonstrated further promise as an early intervention for Alzheimer's disease.

Eating high-fat cheese and cream may be linked to lower dementia risk

Eating more high-fat cheese and high-fat cream may be linked to a lower risk of developing dementia, according to a new study published on December 17, 2025, in Neurology, the medical journal of the American Academy of Neurology.

Lysophosphatidylcholines show gene-dependent effects in early Alzheimer’s disease

A new study presents robust evidence on the role of lysophosphatidylcholines (LPCs) in the onset of Alzheimer's disease. Researchers discovered that LPCs-compounds that transport a variety of healthy fatty acids to the brain-either promote Alzheimer's or protect against it, depending on a person's genetics.

Combined physical frailty and depression may sharply raise dementia risk

Concurrent physical frailty and depression likely boost the risk of dementia in older people, with the interaction of these 2 factors alone contributing around 17% of the overall risk, suggest the findings of a large international study, published in the open access journal General Psychiatry.

Study identifies molecular drivers of cerebral small vessel disease

A new study identifies molecular factors that promote small vessel disease - and an active drug that can restore impaired vascular functions.

New framework tracks response to anti-amyloid therapies in Alzheimer's

In the last few years, progress has been made in the fight against Alzheimer's disease with a class of therapies called anti-amyloid antibodies (anti-Aβ).

New study defines rapidly progressive dementia

A new multicenter study led by Mayo Clinic researchers has established a practical, evidence-based definition for rapidly progressive dementia (RPD), a rare but devastating form of cognitive decline that develops over months instead of years.

Six midlife depressive symptoms linked to dementia decades later

Six particular depressive symptoms when experienced in midlife predict dementia risk more than two decades later, finds a new study led by University College London (UCL) researchers.

Single-pill combination medications may simplify treatment for adults with high blood pressure

Taking one pill that combines two or more blood pressure medications may help adults with high blood pressure (also known as hypertension) lower their blood pressure level faster and more effectively than taking multiple medications separately, and it may also reduce the risk of heart attack and stroke, according to a new scientific statement published today in the American Heart Association's journal Hypertension.

FAU researchers create deep learning model that detects and evaluates Alzheimer's, FTD

Dementia is a group of disorders that gradually impair memory, thinking and daily functioning. Alzheimer's disease (AD), the most common form of dementia, affects about 7.2 million Americans aged 65 and older in 2025.
