Chlamydia pneumoniae found in the eye may aggravate Alzheimer’s disease

by

Chlamydia pneumoniae—a common bacterium that causes pneumonia and sinus infections—can linger in the eye and brain for years and may aggravate Alzheimer’s disease, according to a study from Cedars-Sinai. Published in Nature Communications, the discovery suggests this bacterium can amplify Alzheimer’s disease and points to potential interventions including inflammation-limiting therapies and early antibiotic treatment. The study … Read more

New evidence shows Parkinson’s spreads via immune cells from the gut

by

New research reveals how Parkinson’s spreads from the gut to the brain, with the help of immune cells – offering a new potential therapeutic strategy – in a study in mice led by scientists at the UK Dementia Research Institute at UCL (University College London). Scientists have long theorized that Parkinson’s may start in the … Read more

Brain cell precursors show constant myelin-making drive

by

In experiments with mice, Johns Hopkins Medicine scientists report new evidence that precursors of myelin-producing cells – one of the few brain cell types that continue to be produced in the adult brain – undergo differentiation widely and at a constant pace, rather than “as needed” in response to injury or advancing age. The findings, … Read more

Prolonged exposure to air pollution linked to elevated risk for ALS

by

Prolonged exposure to air pollution can be linked to an elevated risk for serious neurodegenerative diseases like ALS and seems to speed up the pathological process, report researchers from Karolinska Institutet in Sweden. The study is published in the journal JAMA Neurology. We can see a clear association, despite the fact that levels of … Read more

VNS shows durable benefits in Treatment-Resistant depression

by

Two-year data show that adding VNS to standard care can produce lasting symptom, function, and quality-of-life benefits in one of the most difficult-to-treat depression populations. Study: Durability of the benefit of vagus nerve stimulation in markedly treatment-resistant major depression: a RECOVER trial report.

New mouse model sheds light on smell loss and neural regeneration

by

A new study suggests that stem cells thought to be dormant may offer clues to why our sense of smell declines or is lost. Using a newly devised, three-dimensional model to study the regeneration of nerve tissue in the nose, researchers at Tufts University School of Medicine and the Graduate School of Biomedical Sciences (GSBS) and colleagues have discovered … Read more

Fine-tuned AI tool advances objective evaluation of facial palsy

by

A “fine-tuned” artificial intelligence (AI) tool shows promise for objective evaluation of patients with facial palsy, reports an experimental study in the June issue of Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS). The journal is published in the Lippincott portfolio by Wolters Kluwer. We believe that our research offers valuable insights … Read more

Optical stimulation of brain region boosts motor function in Parkinson’s models

by

Researchers are investigating the mechanisms and identifying new areas of the brain that can benefit patients when stimulated. Persons with Parkinson’s disease increasingly lose their mobility over time and are eventually unable to walk. Hope for these patients rests on deep brain stimulation, also known as a brain pacemaker. In a current study, researchers at … Read more

Brain stem nerve cells hold key to safer weight loss treatments

by

A specific group of nerve cells in the brain stem appears to control how semaglutide affects appetite and weight – without causing nausea. The discovery, made at the University of Gothenburg, could pave the way for better drugs to treat obesity. Semaglutide belongs to a group of drugs called GLP-1R agonists and has been shown … Read more

Confocal Microscopy: Identifying Chemotherapy-Induced Neuropathy Biomarkers

by

Archyde: Latest World News, Economy, Entertainment, Health, Technology & Sports Updates Revolutionizing Cancer Care: early Detection of Chemotherapy-Induced Peripheral Neuropathy Chemotherapy, a cornerstone of cancer treatment, frequently enough comes with debilitating side effects. Among the most prevalent is chemotherapy-Induced Peripheral Neuropathy (CIPN), a nerve-damaging condition affecting countless patients. But what if early detection, before symptoms … Read more
