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.

Researchers identify high rates of untreated hypertension in young veterans

Approximately half a million post-9/11 U.S. veterans who served in the military have had high blood pressure, and among them, about half were undiagnosed and one quarter were untreated, according to a new study published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

Cancer-linked mutations in the brain cells may drive Alzheimer’s disease

As the body ages, cells naturally accumulate dozens of genetic mutations each year. New research from Boston Children's Hospital, published in Cell, finds that the brain's resident immune cells, microglia, amass mutations in specific cancer-driving genes yet they don't manifest as cancer.

Microglia actively shape glioblastoma growth and tumor spread

Glioblastoma, the most common and most aggressive brain tumor type in adults, remains difficult to treat because it can infiltrate surrounding brain tissue and spread far beyond the main tumor.

Cognitive decline may signal heart trouble years before a cardiovascular event

In a large ASPREE and ASPREE-XT nested case-control study of older adults without prior cardiovascular disease, people who later experienced a CVD event showed faster cognitive decline beginning roughly 3 to 8 years before the event. Processing speed declined earliest, suggesting that subtle cognitive changes may emerge well before overt cardiovascular disease.

High immune cell ratios may predict future Alzheimer's disease risk

Circulating white blood cells called neutrophils are some of the immune system's first responders. Their numbers shoot up during infection and inflammation, shifting the ratio of neutrophils to other types of immune cells in the blood.

Alzheimer’s monoclonal antibodies fail to deliver meaningful results

Despite reducing amyloid plaques, antibody treatments for Alzheimer's fail to improve cognition, highlighting critical gaps in current therapeutic approaches.

Last patient has completed AlzeCure's Phase Ib clinical study with NeuroRestore ACD856

AlzeCure Pharma AB (publ), a biotech company that develops candidate drugs for diseases affecting the nervous system, focusing on Alzheimer's disease and pain, today announced that the last patient’s last visit (LPLV) has now occurred in the ongoing Phase Ib clinical trial of ACD856, the lead drug candidate within the NeuroRestore platform, which is being developed for Alzheimer’s disease and other indications.

Brain organoids may guide Alzheimer’s diagnosis and treatment

Scientists from Johns Hopkins Medicine report new evidence that clusters of brain tissue derived from the cells of patients with Alzheimer's disease may be used to evaluate how certain patients with the neurodegenerative condition may respond to drugs commonly prescribed to treat psychiatric symptoms of the disorder.

New geometric brain marker predicts successful surgery for iNPH patients

Researchers at the University of Eastern Finland have identified a new geometric marker of the brain ventricles that could help predict which patients with idiopathic normal pressure hydrocephalus (iNPH) will benefit from shunt surgery, according to a recent study published in Fluids and Barriers of the CNS.

Proteomics and AI bring earlier risk prediction into sharper focus

This review examines how high-throughput proteomics is expanding precision medicine by improving biomarker discovery, disease prediction, and drug development. It also shows how AI is helping researchers interpret complex proteomic data while highlighting major barriers such as standardization, validation, and clinical translation.

High-resolution study maps molecular differences across six human cortical regions

A new analysis of individual brain cells across several human brain regions reveals subtle but widespread differences in gene activity between male and female brains. This may help explain why some psychiatric and neurological disorders appear to affect the biological sexes differently, researchers report.

How the immune system may influence Alzheimer’s, Parkinson’s, and related diseases

This review argues that neurodegeneration is shaped not only by toxic protein buildup but also by immune signaling, with microglia and T cells able to either protect the brain or worsen damage depending on context. It also highlights aging, head injury, and viral infection as major forces that reshape CNS immunity and may influence disease progression and future treatment strategies.

Researchers discover a molecular signature to flag dysfunctional aging cells

UCLA researchers have identified a rogue population of immune cells that quietly accumulates in aging tissues and in the livers of people with fatty liver disease. Clearing these cells, they found, dramatically reduced inflammation and reversed liver damage in mice - even while the animals remained on an unhealthy diet.
