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.

Latest Alzheimer's & Dementia News and Research

Statins may help prevent frailty in older adults

Researchers at Mass General Brigham have demonstrated that older U.S. veterans who initiated statin therapy were significantly less likely to develop frailty over time, suggesting that the cholesterol-lowering medications may have healthy aging benefits beyond cardiovascular disease prevention. Results are published in the European Heart Journal.

High obesity levels linked to fewer surgical procedures in Americans

Researchers from LSU's Pennington Biomedical Research Center and collaborating institutions have found that Americans with the highest levels of obesity are undergoing fewer surgical procedures overall.

Common joint supplement may accelerate Alzheimer's disease progression

New research has found an association between taking glucosamine, a popular over-the-counter supplement used for joint pain, and a higher likelihood of progressing from mild cognitive impairment to Alzheimer's disease.

Protein repair defects linked to hidden heart failure

Researchers in the del Monte Lab at the Medical University of South Carolina (MUSC) are the first to observe defects in the protein repair system associated with the peculiar, misfolded protein plaques previously observed in patients with idiopathic dilated cardiomyopathy (IDCM ).

Hospital admissions raise healthcare costs for dementia patients

Dementia makes most things in life more difficult, including hospital care. Though often essential for patients suffering from severe acute illness, hospital care can be confusing for persons with dementia, or PWD.

Blocking immune pathway slows Huntington disease in mouse models

Huntington disease is a rare, inherited brain disorder that progressively destroys nerve cells, leading to worsening movement, cognitive and psychiatric symptoms.

Frailty flags poorer blood pressure control in older women

In 1,038 older adults with hypertension attending outpatient clinics in Vietnam, frailty was more common in women than men, while overall rates of suboptimal blood pressure were similar by sex. Frailty was associated with about twice the odds of suboptimal blood pressure in women, but not in men, highlighting the need to study sex-specific and frailty-informed hypertension care.

Postoperative delirium serves as strongest predictor of cognitive decline

Researchers found postoperative delirium was strongly associated with long-term cognitive decline and the effect was not explained by rehospitalizations, highlighting the long-term impact of delirium on brain health.

Female brain forms fear memories through unique molecular process

Women are twice as likely as men to develop post-traumatic stress disorder (PTSD) - and new research may offer a biological clue as to why.

Researchers develop compound 10 to slow Alzheimer's disease progression

Researchers from ETH Zurich have developed an active ingredient that slows down the progression of typical Alzheimer’s symptoms in mice. This new substance protects nerve cells and could in future alleviate the suffering of Alzheimer’s patients. The active ingredient also shows anti-aging effects.

New artificial intelligence tool helps clinicians distinguish between dementia types

Alzheimer's disease and related dementias are expected to more than double by 2060. As June marks Alzheimer's and Brain Awareness Month, three University of Florida researchers are working to improve clinicians' ability to distinguish between these diseases - a critical step toward earlier diagnosis and better outcomes.

Antibody fragment offers safer alternative for Alzheimer disease treatment

In 2025, the European Medicines Agency approved two antibodies for Alzheimer's disease: lecanemab (Leqembi, from Biogen) and donanemab (KisunlaTM, from Eli Lilly and Company), both based on immunotherapy (the use of molecules from the immune system to treat diseases).

Senior Care Authority kicks off Alzheimer's and Brain Awareness Month with six science-backed habits that may help reduce dementia risk

An estimated 7.4 million Americans aged 65 and older are now living with Alzheimer's disease, according to the Alzheimer's Association's 2026 Alzheimer's Disease Facts and Figures report, and that number is projected to climb to nearly 13 million by 2050.

What older adults eat may shape dementia risk

Higher ultraprocessed food intake was associated with increased risks of dementia, cognitive impairment with no dementia, and the combined outcome among older US adults in the Health and Retirement Study. Minimally processed food intake showed the opposite pattern, although the observational findings require cautious interpretation because diet was self-reported and cognitive outcomes were not clinically diagnosed.
