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.

New insight into how molecular measures of aging relate to neuroimaging markers of brain health

A new research paper was published in Volume 18 of Aging-US on April 7, 2026, titled "Association of epigenetic age acceleration with MRI biomarkers of aging and Alzheimer's disease neurodegeneration."

Scientists identify STING switch driving inflammation in Alzheimer’s disease

The brain has its own immune system, which detects threats and mounts a defense. A growing body of evidence has shown that in Alzheimer's disease, those immune cells are chronically overactivated, causing inflammation that damages the connections between brain cells.

Unraveling the mystery of cognitive resilience in aging brains

Some brains resist Alzheimer's, even when the disease is already present. Researchers at the Netherlands Institute for Neuroscience have found that this likely depends on how specific brain cells, known as immature neurons, respond to damage caused by the disease.

Revisiting memories together improves emotional wellbeing in dementia care

Caring for a family member with dementia can feel like losing a loved one who is still alive, but a new study suggests that revisiting memories together through a simple digital tool can help ease that grief and even strengthen the patient-caregiver bond.

L-arginine stabilizes protein droplets and prevents harmful fibril formation

Protein droplets serve important biological functions within cells, but in neurodegenerative diseases like Alzheimer's, these liquid-like droplets can form solid-like clumps known as fibrils.

Researchers receive NIH grant to accelerate Alzheimer's drug discovery efforts

Dr. Damian Young, investigator at Texas Children's Duncan Neurological Research Institute (Duncan NRI) and director of the Center for Drug Discovery at Baylor College of Medicine, along with collaborators has been awarded a $6.7 million grant from the National Institute on Aging (NIA), part of the National Institutes of Health (NIH), to develop new approaches to rapidly identify potential treatments for Alzheimer's disease and related dementias with the goal of accelerating the discovery of new therapies.

New human cell model replicates key mechanisms of neurodegenerative diseases

Researchers at LMU have developed a human cell model that replicates key mechanisms of neurodegenerative diseases - with potential for novel therapies.

Severe strokes significantly increase the risk of progressive dementia

As stroke severity increases, the risk of progressive cognitive decline and dementia substantially escalates, according to a national study led by Michigan Medicine researchers.

Metabolic health may shape future dementia risk for Latino communities

Researchers from the University of California San Diego have found that diabetes is linked to changes in measurable biological signals in the blood that are associated with Alzheimer's disease and brain damage in Latino adults.

Astrocytes form complex networks across the mouse brain

Cells long thought to play a secondary role in brain function build their own far-reaching connections, a new study in mice showed. These pathways appear to connect distant regions in ways that have not been mapped before.

Virtual neurology visits match in-person care outcomes

For people who see a neurology clinician for the first time, a new study has found that being seen virtually vs. in-person made no difference in how soon they needed more care.

Poor sleep linked to higher dementia risk in epilepsy

For people with epilepsy, getting poor sleep was associated with a higher risk of dementia compared to people without epilepsy, according to a study published April 22, 2026, in Neurology, the medical journal of the American Academy of Neurology.

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.
