- Why Trump’s leg swelling could be a warning sign for millionson July 18, 2025 at 7:12 am
President Trump s diagnosis of Chronic Venous Insufficiency (CVI) has brought renewed attention to a frequently overlooked yet dangerous condition. CVI affects the ability of veins especially in the legs to return blood to the heart, often leading to swelling, pain, skin changes, and ulcers. The American Heart Association warns that CVI isn t just a cosmetic issue; it's strongly linked to cardiovascular disease and increased mortality, even when other risk factors are accounted for. Seniors, smokers, those with sedentary lifestyles, and people with obesity are particularly at risk.
- Dogs can detect Parkinson’s years before symptoms—with 98% accuracyon July 16, 2025 at 4:22 pm
Dogs trained to detect Parkinson’s disease using scent have shown remarkable accuracy in new research. In a double-blind trial, they identified skin swabs from people with Parkinson’s with up to 80% sensitivity and 98% specificity, even when other health conditions were present. The findings offer hope for a simple, non-invasive diagnostic method using biomarkers that appear long before traditional symptoms, potentially allowing earlier treatment and slowed disease progression.
- One shot, seven days: Long-acting levodopa gel tackles Parkinson’s tremorson July 14, 2025 at 4:04 pm
Researchers in Australia have created a biodegradable gel that delivers Parkinson’s medications through a single weekly shot, replacing the need for multiple daily pills. Injected just under the skin, the gel steadily releases levodopa and carbidopa for seven days, helping keep tremors and stiffness in check while easing side effects linked to fluctuating doses.
- Researchers grow 400+ brain cell types—a leap for Alzheimer’s and Parkinson’s researchon July 12, 2025 at 8:45 am
Scientists at ETH Zurich have broken new ground by generating over 400 types of nerve cells from stem cells in the lab, far surpassing previous efforts that produced only a few dozen. By systematically experimenting with combinations of morphogens and gene regulators, the researchers replicated the vast diversity of neurons found in the human brain. This breakthrough holds major promise for studying neurological diseases like Alzheimer’s and Parkinson’s, creating more accurate models for drug testing, and eventually even enabling neuron replacement therapies.
- This tiny brain molecule could hold the key to learning, memory—and Alzheimer’s treatmenton July 12, 2025 at 8:18 am
A team of researchers has discovered that a protein called cypin plays a powerful role in helping brain cells connect and communicate, which is crucial for learning and memory. By uncovering how cypin tags certain proteins at synapses and interacts with the brain’s protein recycling system, scientists are opening doors to possible treatments for Alzheimer's, Parkinson's, and traumatic brain injuries. This breakthrough could be the first step toward boosting brain resilience and cognition.
- How a hidden brain circuit fuels fibromyalgia, migraines, and PTSDon July 11, 2025 at 3:37 am
What if your brain is the reason some pain feels unbearable? Scientists at the Salk Institute have discovered a hidden brain circuit that gives pain its emotional punch—essentially transforming ordinary discomfort into lasting misery. This breakthrough sheds light on why some people suffer more intensely than others from conditions like fibromyalgia, migraines, and PTSD. By identifying the exact group of neurons that link physical pain to emotional suffering, the researchers may have found a new target for treating chronic pain—without relying on addictive medications.
- Your Brain’s Hidden Defenses Against Alzheimer’son July 10, 2025 at 10:00 am
Scientists at UCSF combined advanced brain-network modeling, genetics, and imaging to reveal how tau protein travels through neural highways and how certain genes either accelerate its toxic journey or shield brain regions from damage. Their extended Network Diffusion Model pinpoints four gene categories that govern vulnerability or resilience, reshaping our view of Alzheimer’s progression and spotlighting fresh therapeutic targets.
- Alzheimer’s doesn’t strike at random: These 4 early-warning patterns tell the storyon July 7, 2025 at 2:29 pm
UCLA scientists mined millions of electronic health records and uncovered four distinct “roadways” that funnel people toward Alzheimer’s—ranging from mental-health struggles to vascular troubles. Following these breadcrumb trails proved far better at predicting who will develop dementia than single risk factors. The findings hint that spotting—and halting—specific sequences early could rewrite how we prevent the disease.
- Cough medicine turned brain protector? Ambroxol may slow Parkinson’s dementiaon July 6, 2025 at 1:01 pm
Ambroxol, long used for coughs in Europe, stabilized symptoms and brain-damage markers in Parkinson’s dementia patients over 12 months, whereas placebo patients worsened. Those with high-risk genes even saw cognitive gains, hinting at real disease-modifying power.
- Scientists reverse Parkinson’s symptoms in mice — Could humans be next?on July 6, 2025 at 3:13 am
Scientists at the University of Sydney have uncovered a malfunctioning version of the SOD1 protein that clumps inside brain cells and fuels Parkinson’s disease. In mouse models, restoring the protein’s function with a targeted copper supplement dramatically rescued movement, hinting at a future therapy that could slow or halt the disease in people.
- Parkinson’s reversal? One drug brings dying brain cells back to lifeon July 4, 2025 at 3:44 am
Stanford researchers discovered that dialing down an overactive enzyme, LRRK2, can regrow lost cellular “antennae” in key brain cells, restoring vital dopamine communication and neuroprotective signals in a mouse model of genetic Parkinson’s. After three months on the LRRK2-blocking drug MLi-2, damaged circuits revived and early signs of neuronal recovery emerged, hinting that timely treatment could not only halt but reverse disease progression—and perhaps benefit other Parkinson’s forms.
- A midlife MRI that spots rapid aging and signals disease long before symptomson July 2, 2025 at 11:52 am
A new brain scan tool shows how quickly your body and mind are aging. It can spot early signs of diseases like dementia, long before symptoms begin. The scan looks at hidden clues in your brain to predict future health.
- Scientists just found a sugar switch that protects your brain from Alzheimer'son June 30, 2025 at 2:04 pm
Scientists have uncovered a surprising sugar-related mechanism inside brain cells that could transform how we fight Alzheimer’s and other dementias. It turns out neurons don’t just store sugar for fuel—they reroute it to power antioxidant defenses, but only if an enzyme called GlyP is active. When this sugar-clearing system is blocked, toxic tau protein builds up and accelerates brain degeneration.
- Brain scan breakthrough reveals why Parkinson’s drugs don’t always workon June 29, 2025 at 8:35 am
Researchers are using an advanced brain imaging method called MEG to understand why Parkinson’s drug levodopa doesn’t work equally well for everyone. By mapping patients’ brain signals before and after taking the drug, they discovered that it sometimes activates the wrong brain regions, dampening its helpful effects. This breakthrough could pave the way for personalized treatment strategies, ensuring patients receive medications that target the right areas of their brain more effectively.
- This brain scan sees Alzheimer’s coming—but only in some brainson June 29, 2025 at 8:13 am
USC researchers have found a promising new brain scan marker that could better detect Alzheimer’s risk — but only for some. The tau-based benchmark works in Hispanic and White populations when paired with another Alzheimer’s protein, amyloid, but falls short for Black participants, revealing critical gaps in current diagnostics.
