New swallowable device enables noninvasive gut nerve stimulation

Scientists have long struggled with how to study the gut's vast nervous system - often called the body's 'second brain' - without damaging it.

Hormone therapy type may influence postmenopausal cognitive health

The type of estradiol-based hormone therapy taken during and after menopause, such as patches or pills, may be associated with differences in memory performance, according to a study published on August 27, 2025, in Neurology, the medical journal of the American Academy of Neurology.

Multi-analyte test accurately identifies brain cancers using cerebrospinal fluid

A novel, multi-analyte test developed by researchers at the Johns Hopkins Kimmel Cancer Center, its Ludwig Center and the Johns Hopkins Department of Neurosurgery can accurately identify brain cancers using small samples of cerebrospinal fluid (CSF), offering a promising new tool to guide clinical decision-making.

Routine eye exams may help detect Alzheimer’s years before symptoms appear

Within the next few years, doctors may be able to spot signs of Alzheimer's disease and other dementias using routine eye exams well before symptoms appear, a new study suggests.

Transcutaneous vagal nerve stimulation shows promise for gastrointestinal disorders

Imbalanced autonomic function, characterized by reduced vagal activity and sympathetic dominance, is increasingly recognized in various gastrointestinal (GI) disorders.

Do GLP-1 drugs shrink your muscles? New study explains the risks and what to do

GLP-1 receptor agonists are transforming obesity and diabetes care, but may reduce skeletal muscle mass, raising concerns about sarcopenic obesity. This comprehensive review explores the mechanisms, clinical implications, and mitigation strategies, including exercise, protein intake, and adjunct therapies.

Positive emotion bias in aging may signal cognitive decline

As people age, they display a bias in recognizing emotions as positive-to the point of improperly labeling neutral or negative emotions as positive.

Neural signature reveals how self-preoccupation manifests in the brain

People tend to be self-preoccupied. Self-interest is good when it ensures that one's needs are met, but it can also be maladaptive; research shows that the tendency to self-focus promotes the occurrence of depression and anxiety and can even prolong these conditions.

Scientists discover molecular brake that halts brain cell repair in multiple sclerosis

A team of scientists led by the Institute for Glial Sciences (IGS) at Case Western Reserve University's School of Medicine has discovered a built-in "brake" that controls when key brain cells mature.

How a single gene reshapes pain perception through polyamine signaling

Researchers have identified SLC45A4 as a neuronal polyamine transporter genetically linked to human chronic pain. Loss of this gene in mice disrupts polyamine balance, alters spinal GABA levels, and reduces heat and tonic pain sensitivity.

Insights into the clinical presentation and management of sellar chondrosarcomas

Chondrosarcomas are a malignant form of bone cancer that is composed of cartilage-forming tumor cells. Sellar chondrosarcomas, which occur in the sellar region at the base of the skull, are a very rare manifestation of chondrosarcoma, making up only around 0.2% of all tumors found in the skull.

Hypothalamic neurons help maintain blood sugar during daily activities

The brain controls the release of glucose in a wide range of stressful circumstances, including fasting and low blood sugar levels.

Gut bacteria and insomnia influence each other in small but significant ways, study shows

Scientists used Mendelian randomisation to explore the two-way relationship between gut microbiota and insomnia, analyzing GWAS data from over 386,000 individuals and two major microbiome cohorts. The study found only limited taxa surviving strict correction, suggesting small but causal links that highlight the gut–brain axis in sleep health.

New study uncovers a surprising mechanism of resistance to immunotherapy

A new international study led by researchers at Moffitt Cancer Center, the Karolinska Institutet and the University of Texas MD Anderson Cancer Center has uncovered a surprising mechanism of resistance to immunotherapy: cancer's ability to injure nearby nerves.

One-stage hybrid operation improves safety in treating hypervascular brain and spinal tumors

Hypervascular tumors of the brain and spinal cord pose serious challenges for neurosurgeons due to their dense blood vessel networks, which can lead to heavy bleeding and increased surgical risk.

Metabolic syndrome linked to higher risk of Parkinson's disease

Having a larger waistline, high blood pressure and other risk factors that make up metabolic syndrome is associated with an increased risk of Parkinson's disease, according to a study published on August 20, 2025, in Neurology, the medical journal of the American Academy of Neurology.

20 Aug 2025

Cancer cells break down nerve covers causing immune exhaustion and therapy resistance

Cancer cells can break down the protective covers around nerves, causing nerve injury that triggers chronic inflammation leading to immune exhaustion and eventual resistance to immunotherapy, according to new research from The University of Texas MD Anderson Cancer Center.

Texas Children’s successfully treats AADC deficiency using FDA-approved gene therapy

Texas Children's is pleased to announce that a three-year-old girl has been successfully treated with the first-ever FDA-approved gene therapy treatment for AADC deficiency.
