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.

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.

A senescence-based therapeutic approach for temporal lobe epilepsy

Temporal lobe epilepsy, which results in recurring seizures and cognitive dysfunction, is associated with premature aging of brain cells.

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.

Long-approved drug shows promise in slowing neuron loss in Alzheimer’s disease

Scientists at the University of Colorado Anschutz have discovered that while brain neuron changes, including cell loss, may begin in early life, a drug long-approved for other conditions might be repurposed to slow this damage, offering new hope for those with Alzheimer's disease (AD) and other cognition issues.

Researchers point to mitochondria as a missing link between mental health and brain function

A stressful year leads to anxiety. Lasting isolation gives way to depression. An old trauma nags until it becomes paralyzing.

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

Junk' DNA may hold new clues to Alzheimer’s disease

When most of us think of DNA, we have a vague idea it's made up of genes that give us our physical features, our behavioral quirks, and keep our cells and organs running.

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.

Hyperphosphorylated tau may help protect the brain from infection

One of the main proteins that contributes to Alzheimer's disease is called phospho-tau (p-tau). When p-tau gets too many phosphate groups attached to it (a process called hyperphosphorylation), it starts to stick together and form clumps called "tangles" inside of brain nerve cells.

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.
