Simple, noninvasive scans may one day help spot risk earlier—by looking at the brain’s vascular health, not just its plaques. Tue, 24 Feb 2026 10:21:58 EST https://www.sciencedaily.com/releases/2026/02/260224023159.htm https://www.sciencedaily.com/releases/2026/02/260212025620.htm A newly identified protein may hold the key to rejuvenating aging brain cells. Researchers found that boosting DMTF1 can restore the ability of neural stem cells to regenerate, even when age-related damage has set in. Without it, these cells struggle to renew and support memory and learning. The findings raise hopes for treatments that could slow or even reverse aspects of brain aging.

The early-stage clinical trial involves implanting lab-grown dopamine-producing cells directly into a key movement-control region of the brain, with the hope of slowing disease progression and improving motor function.

Adults who exercised regularly for a year showed brains that appeared nearly a year younger than those who didn’t change their habits. The study focused on midlife, a critical window when prevention may offer long-term benefits. Even small shifts in brain age could add up over decades.

Scientists discovered that severe drops in the brain’s energy supply help drive the disease—and restoring that balance can reverse damage, even in advanced cases. In mouse models, treatment repaired brain pathology, restored cognitive function, and normalized Alzheimer’s biomarkers. The results offer fresh hope that recovery may be possible.

Using advanced 7T MRI, they found these tiny pulsations grow stronger with age and vascular risk, disrupting the brain’s waste-clearing systems. The discovery may explain how circulation changes contribute to Alzheimer’s and other neurodegenerative diseases.

Dr. Elaine Bearer has created a new way to classify these changes, showing that many people diagnosed with Alzheimer’s also suffer from vascular damage that quietly destroys brain tissue. Even more surprising, she’s finding microplastics inside the brain that appear linked to inflammation and memory loss.

Scientists discovered that most genetic risks linked to these diseases act not in neurons, but in the blood vessels and immune cells that form the blood-brain barrier.

The new framework expands the assessment beyond immediate clinical symptoms. Added criteria would include biomarkers, CT and MRI scans, and factors, such as other medical conditions and how the trauma occurred.

But a new multicenter study could lead to a cost-effective blood test to identify changes occurring near the top of the chain, potentially identifying at-risk patients at an earlier stage. Wed, 18 Dec 2024 13:17:28 EST https://www.sciencedaily.com/releases/2024/12/241218131728.htm https://www.sciencedaily.com/releases/2024/12/241216125642.htm In the U.S., atrial fibrillation (AF), a heart condition that causes an irregular heartbeat in the upper chambers of the heart, affects up to one in three people in their lifetime. Significant complications associated with this condition include ischemic stroke, heart failure, myocardial infarction, chronic kidney disease, dementia and mortality. In a new review article scientists summarize the current evidence regarding the epidemiology, pathophysiology, diagnosis and management of AF.

A possible explanation for this side effect is that the treatment interferes with immune regulation in the heart's largest blood vessels, a new study suggests.

This revealed a mechanism that results in fewer newborn neurons from the stem cell niche surviving after stroke, thereby significantly limiting the neurogenic reaction of the subventricular zone to repair the brain. This fundamental understanding of the cellular processes in the brain could help in future to boost the body's own repair to replace lost neurons and ameliorate the consequences of stroke.

Atherosclerosis is the build-up of plaque in the arteries which causes their narrowing and is a primary cause of ischemic heart disease (IHD) and ischemic stroke (IS), major contributors to deaths caused by cardiovascular diseases globally. This theranostic approach represents a significant advancement in the field of cardiovascular medicine as it offers a promising alternative to current medical practices for the management of atherosclerosis.

How can almost identical cells perform such different functions? The key lies in the methylation of their genetic material, which endowes these special astrocytes with stem cell properties. In mice, the researchers showed that experimentally induced lack of blood supply in the brain epigenetically reprograms astrocytes into brain stem cells, which in turn can give rise to nerve progenitor cells. This discovery shows that astrocytes could potentially be used in regenerative medicine to replace damaged nerve cells.

Gr3-MB is one of the most aggressive forms of brain cancer in children and is associated with metastatic spread and poor survival. The researchers showed that eliminating the small population of stem-like cells present in Gr3-MB tumors led to tumor shrinkage in preclinical models. Although more research is needed, this novel approach may lead to new ways to treat children with Gr3-MB.

But getting intensive, frequent rehabilitation therapy can be challenging and expensive. Now, researchers are developing a new technology that could allow stroke patients to undergo rehabilitation exercises at home by tracking their wrist movements through a simple setup: a smartphone strapped to the forearm and a low-cost gaming controller called the Novint Falcon.

Researchers have found that heart failure leaves a 'stress memory' in the form of changes to the DNA modification of hematopoietic stem cells, which are involved in the production of blood and immune cells called macrophages. These immune cells play an important role in protecting heart health.

The new observational study looked at the relationship between stroke recovery and white matter hyper-intensities (WMHs) -- areas of age-related damage in the brain's white matter, which represent vascular dysfunction and are known to impact cognitive functions.

The coordination between the two clocks (central and peripheral) guarantees 50% of the circadian functions of tissues, including vital processes such as the cell cycle, DNA repair, mitochondrial activity, and metabolism. Synchronization between the central brain clock and peripheral ones prevents premature muscle aging and improves muscle function, suggesting new strategies to tackle age-related decline through circadian rhythm modulation.

Previous research has found that this may increase the risk of heart disease and stroke. In this study, episodes of anxiety and sadness did not trigger the same change in functioning of the blood vessel lining.

Those with CLTI often suffer severe pain even at rest, caused by fatty plaque buildup obstructing blood flow, typically to the leg or foot.
