By combining laser-based imaging with machine learning, they uncovered chemical changes that spread unevenly across the brain and extend beyond amyloid plaques. Key memory regions showed major shifts in cholesterol and energy-related molecules. The findings hint that Alzheimer’s is a whole-brain metabolic disruption—not just a protein problem.

By measuring a protein called p-tau217, the model predicts symptom onset within roughly three to four years. The protein mirrors the silent buildup of amyloid and tau in the brain long before memory loss appears. This advance could speed up preventive drug trials and eventually guide personalized care.

They identified multiple DNA regions linked to bowel movement frequency, confirming known gut pathways and revealing new ones. The biggest surprise was a strong connection to vitamin B1, a common nutrient not usually linked to digestion.

Researchers found that up to nine in ten cases could be linked to the APOE gene — even including a common version once considered neutral. The discovery reshapes how scientists think about risk and prevention. It also highlights a major opportunity for new treatments aimed at a single biological pathway.

A comprehensive review found they can help control blood sugar, support heart and gut health, and reduce inflammation and oxidative stress. Laboratory and human studies also suggest bamboo may promote beneficial gut bacteria and reduce toxic compounds in cooked foods. However, bamboo must be pre-boiled to avoid natural toxins.

These blockages, easily seen on standard MRI scans, are tied to toxic protein buildup linked to memory loss and cognitive decline. In some cases, they may signal Alzheimer’s earlier than other commonly used brain markers. This could help physicians detect the disease earlier, before irreversible damage sets in.

Scientists discovered that vitamin C from food travels through the bloodstream into every layer of the skin, boosting collagen and skin renewal. People who ate two vitamin C–packed kiwifruit daily showed thicker, healthier skin. The findings suggest glowing skin really does start from within.

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.

Scientists found that an experimental drug, NU-9, blocks this early damage in mice and reduces inflammation linked to disease progression. The treatment was given before symptoms appeared, targeting the disease at its earliest stage. Researchers say this approach could reshape how Alzheimer’s is prevented and treated.

Kids on plant-based diets often had better heart health markers, including lower “bad” cholesterol, and consumed more fiber and vitamins. But the study also flagged common nutrient gaps—especially vitamin B12 and calcium—without supplementation. Experts say plant-based eating is achievable for kids, but only with careful planning.

Long-term imaging and plasma data show that obese individuals experience much faster increases in proteins linked to neurodegeneration and amyloid buildup. Surprisingly, blood tests detected these changes earlier than PET scans. The results point to obesity as a major, modifiable contributor to Alzheimer’s progression.

The new compounds, which combine vitamin K with retinoic acid, activate the mGluR1 receptor to drive neurogenesis. They also efficiently cross the blood-brain barrier and show stability in vivo. This discovery could pave the way for regenerative treatments for Alzheimer’s and related diseases.

Unlike D2, vitamin D3 enhances the immune system’s first line of defense against infections. This raises questions about which type of supplement should be prioritized.

Their decade-long research shows that lithium depletion—caused by amyloid plaques binding to it—triggers early brain changes that lead to memory loss. By testing new lithium compounds that evade plaque capture, they reversed Alzheimer’s-like damage and restored memory in mice at doses far lower than those used in psychiatric treatments.

The study suggests omega-rich diets could be key, but clinical trials are needed.

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. Mon, 04 Aug 2025 23:41:01 EDT https://www.sciencedaily.com/releases/2025/08/250803233111.htm https://www.sciencedaily.com/releases/2025/07/250730030402.htm In an exciting breakthrough, researchers have identified cancer drugs that might reverse the effects of Alzheimer's disease in the brain. By analyzing gene expression in brain cells, they discovered that some FDA-approved cancer medications could reverse damage caused by Alzheimer's.

Their study revealed that individuals with both conditions had twice the iron levels and far more oxidative damage than others. The culprit appears to be ferroptosis, an iron-triggered cell death mechanism, which is especially damaging in sensitive brain regions.

Breathing in wildfire smoke or automobile-related city smog doesn't just increase the risk of asthma and heart disease -- it may also contribute to brain conditions as diverse as Alzheimer's and autism. Scientists have discovered how a chemical change in the brain -- which can be triggered by inflammation and aging as well as toxins found in air pollution, pesticides, wildfire smoke and processed meats -- disrupts normal brain cell function. Known as S-nitrosylation, this chemical change prevents brain cells from making new connections and ultimately results in cellular death, the team discovered.

It is believed most humans are exposed to this virus -- called cytomegalovirus or HCMV -- during the first few decades of life. According to the new research, in some people, the virus may linger in an active state in the gut, where it may travel to the brain via the vagus nerve -- a critical information highway that connects the gut and brain. Once there, the virus can change the immune system and contribute to other changes associated with Alzheimer's disease. This virus may be a target for antiviral treatments.

The study checked the amounts of choline and iodine in nonprescription and prescription prenatal vitamins. The research also checked for toxic metals like arsenic, lead and cadmium. The researchers tested a sample of 47 different prenatal vitamins (32 nonprescription and 15 prescription products) bought from online and local stores where people commonly shop.

According to researchers who discovered this new view, the first, early phase happens slowly and silently -- before people experience memory problems -- harming just a few vulnerable cell types. In contrast, the second, late phase causes damage that is more widely destructive and coincides with the appearance of symptoms and the rapid accumulation of plaques, tangles, and other Alzheimer's hallmarks.

Its disordered active centre becomes a defined structure with special functions. The protein plays a key role in the production of inositol, which is also known as vitamin B8, and fulfills important tasks in the body. Researchers have succeeded for the first time in observing the protein as it re-structures.

Moreover, the researchers uncovered microRNA candidate molecular biomarkers that associate with current Amyloid, Tau, and Neurodegeneration (A/T/N) Alzheimer's biomarkers.
