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

Untreated sleep apnea may cost the UK and US billions annually

Untreated obstructive sleep apnea may be costing the UK and US economies billions of pounds/dollars in lost productivity every year, with a considerable proportion of working age adults experiencing symptoms indicative of the breathing disorder, suggests an analysis published online in the journal Thorax.

WashU Medicine receives 80 million to study exceptional longevity

Researchers at Washington University School of Medicine in St. Louis have received an $80 million grant to continue research into the mysteries of exceptional longevity.

Study finds microplastics in most prostate tumors

Small fragments of plastic were found in nine out of 10 patients with prostate cancer, and in higher levels inside tumors than in nearby noncancerous tissue, a new study finds.

Study captures real-time protein clumping linked to Alzheimer’s

An Oregon State University scientist and a team of undergraduate students have uncovered real-time insights into a chemical process linked with Alzheimer's disease, paving the way toward better drug designs.

Study connects vascular health to early Alzheimer’s brain changes

Subtle changes in how blood flows through the brain and how brain tissue uses oxygen may be closely linked to Alzheimer's disease risk, according to new research from the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC.

Study finds widespread off-label use of antipsychotics among older people

The use of antipsychotic medications for purposes other than those officially approved is common among older adults in Finland.

New review explores whether berries can slow cognitive decline linked to obesity

This systematic review in Nutrients evaluates human studies investigating whether polyphenol-rich berry consumption can modulate obesity-related metabolic dysfunction and support cognitive performance, particularly in individuals at risk of mild cognitive impairment. Evidence suggests modest memory benefits and possible metabolic improvements, although biomarker findings and long-term clinical relevance remain uncertain.

Study identifies PPP2R5C blood marker that may detect Alzheimer’s disease earlier

Emerging evidence suggests reduced plasma PPP2R5C levels may serve as an early indicator of Alzheimer’s disease before overt clinical symptoms appear. The protein appears linked to tau regulation, autophagy pathways, and cognitive decline, supporting its potential diagnostic relevance.

Blood test models predict when Alzheimer’s symptoms may start years in advance

Researchers developed plasma p-tau217–based clock models that estimate when cognitively unimpaired individuals with Alzheimer’s pathology may develop symptomatic disease. The models predicted symptom onset within about three to four years and may help improve clinical trial selection while remaining unsuitable for individual clinical decisions at present.

New maps of mouse brains reveal patterns of myelin formation

Johns Hopkins scientists say they have used 3D imaging, special microscopes and artificial intelligence (AI) programs to construct new maps of mouse brains showing a precise location of more than 10 million cells called oligodendrocytes.

Grant supports research into how microglia may spread toxic tau in Alzheimer’s

A researcher with the Glenn Biggs Institute for Alzheimer's and Neurodegenerative Diseases at UT Health San Antonio has received a two-year, $402,500 grant award from the Cure Alzheimer's Fund to study how microglia, the brain's resident immune cells, paradoxically might contribute to the spread of toxic forms of tau protein in the disease.
