This approach is reversible, controllable, and clinically feasible, providing a potential solution for chronic inflammatory d...
A new study published in PNAS shows that vagus nerve stimulation significantly improves measures of disease activity in patients with rheumatoid arthritis. The treatment, which involves stimulating the vagus nerve with an implantable device, has been shown to inhibit cytokine production and attenuate disease severity in humans.
Researchers report successful reduction of depressive symptoms in patients using a novel non-invasive method of vagus nerve stimulation. The transcutaneous approach, which stimulates the vagus nerve through electrodes clipped onto the ear, shows promise as a low-cost and safe treatment option.
A new study published in the journal Stroke demonstrates that vagus nerve stimulation can improve recovery in stroke patients by reducing impairments and increasing motion and strength in affected arms. The trial involved 20 patients with arm weakness due to stroke, showing significant potential for reducing disabilities.
Researchers at UT Dallas have made a breakthrough in developing vagus nerve stimulation (VNS) therapy for spinal cord injuries outside the forebrain. The study found that VNS paired with rehabilitation can restore 75% more forelimb strength after a cervical spinal cord injury, opening up new possibilities for treatment.
Researchers found that patients who had undergone vagotomy were protected against developing Parkinson's disease, with a risk halved after 20 years. The study suggests that Parkinson's disease begins in the gut and spreads via the vagus nerve to the brain.
Scientists have identified two sensory neuron subtypes controlling different respiratory functions in mice, revealing a complex vagus nerve system that may lead to targeted therapies. The study sheds light on the molecular mechanisms underlying breathing control and has implications for treating various conditions.
The ANTHEM-HF study shows significant improvement in left ventricular ejection fraction and 6-minute walk test distance with both left and right vagus nerve stimulation. However, the improvement was significantly less with left-sided VNS compared to right-sided VNS.
New research shows how psychology affects our daily lives, revealing insights into common emotions, love, and meaning. Scientists explored emotional connections to spaces, the impact of micro-moments on well-being, moral questions and myths about life's meaning.
Researchers at UT Dallas have developed a new treatment for stroke recovery using vagus nerve stimulation, which showed full recovery of forelimb strength in rats. The treatment involves pairing stimulation with rehabilitative training to enhance neuroplasticity and improve recovery outcomes.
Researchers found that vagus nerve stimulation brings about changes in brain metabolism weeks or months before patients begin to feel better.
