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.

AI-assisted model based on blood proteins could help predict retinal degeneration in diabetics

An AI-assisted model based on 71 different blood proteins could help doctors better predict retinal degeneration in diabetic patients before symptoms occur, according to a study published June 2nd in the open access journal PLOS Medicine by Huangdong Li from the Guangdong Provincial Clinical Research Center for Ocular Diseases in Guangzhou, China, and colleagues.

Allen Institute launches global research initiative to accelerate new treatments for brain disorders

The Allen Institute, together with partner organizations, today launched the Brain Health accelerator: an ambitious global research initiative seeking to identify the specific brain cells and circuits affected in neurodegenerative disease and other brain disorders and use that knowledge to accelerate the development of new treatments.

How dysregulated collagen IV homeostasis causes cerebral microbleeds

Millions of older adults have tiny brain hemorrhages called cerebral microbleeds, which are strongly associated with dementia, cognitive decline, and stroke.

New reference models track lifespan changes in brain wiring

Researchers at the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have created one of the largest reference models ever developed for the human brain, using diffusion MRI scans from more than 54,000 people to chart how the brain's communication pathways develop, mature, and decline across the lifespan.

Cellular reprogramming helps outsmart progressive Alzheimers disease

A team led by researcher José Vicente Sánchez Mut at the Institute for Neurosciences (IN), a joint center of the Spanish National Research Council (CSIC) and the Miguel Hernández University of Elche (UMH), together with researcher Johannes Gräff at the École Polytechnique Fédérale de Lausanne (EPFL), has identified an experimental molecule capable of "reprogramming" the brain's immune cells to restore part of their protective function against Alzheimer's disease.

New brain probe simultaneously records and controls neuron activity

A new breakthrough technology, co-developed by UCL scientists, that simultaneously records and manipulates neuron activity deep within the brain could transform our understanding of neural circuits and neurological conditions, such as Alzheimer's disease and schizophrenia.

Lower Alzheimer’s amyloid levels in Black and Latinx adults

Findings show lower amyloid PET positivity in Black and Latinx adults with cognitive impairment, highlighting disparities in dementia diagnosis and treatment.

Why new Alzheimer’s drugs are dividing regulators worldwide

The Lancet World Report examines why regulators in the US, UK, and Europe have reached different decisions on new amyloid-targeting Alzheimer’s drugs despite evidence that they can modestly slow clinical decline. It highlights the unresolved balance among benefits, safety risks, costs, access, and the need for broader, earlier, and more patient-centered treatment strategies.

Researchers uncover new clues about the origin of Alzheimer's tau tangles

Researchers at Columbia University have uncovered new clues about the earliest molecular events that may trigger Alzheimer's disease, shedding light on how toxic tau filaments begin to form in the brain.

Gladstone scientists track exact routes used to clear brain waste

Think of the brain as if it were a house. Insulated from its environment, a house relies on complex networks-pipes, drains, and disposal systems-that interface with the outside world to keep the home functional on the inside.

Scientists uncover shared gene signatures that reveal how mammals age

Researchers mapped more than 11,000 transcriptomes across mice, rats, macaques, and humans, revealing conserved molecular signatures of aging and mortality across tissues, species, and cell types. The study developed interpretable transcriptomic clocks that track age, mortality-related molecular change, chronic disease signals and responses to lifespan-altering interventions.
