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.

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.

Imaging-enhanced knowledge graphs reveal new targets for heart disease treatment

Knowledge graphs are a powerful tool for bringing together information from biological databases and linking what is already known about genes, diseases, treatments, molecular pathways and symptoms in a structured network.

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.

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.

Restoring brain energy balance reverses 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.

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.

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.

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.
