For decades, scientists have noted an intriguing similarity between a deficiency in vitamin B12 and multiple sclerosis (MS), a chronic disease in which the body’s immune system attacks the CNS and which can produce neurodegeneration. Both vitamin B12 (also known as cobalamin) deficiency and MS produce similar neurological symptoms, including numbness or tingling in hands […]

Some Covid-19 vaccines safely and effectively used lipid nanoparticles (LNPs) to deliver messenger RNA to cells. A new MIT study shows that different nanoparticles could be used for a potential Alzheimer’s disease (AD) therapy. In tests in multiple mouse models and with cultured human cells, a newly tailored LNP formulation effectively delivered small interfering RNA […]

In some diseases, the underlying processes can start years before a diagnosis is made. A new study finds that people who later develop multiple sclerosis (MS) are more likely to have conditions like depression, constipation and urinary tract infections five years before their MS diagnosis than people who do not develop MS.  The conditions were […]

3D eye scans can reveal vital clues about kidney health that could help to track the progression of disease, research suggests. Researchers used highly-magnified images to detect changes to the retina — the layer of tissue at the back of the eye that senses light and sends signals to the brain. They found that the […]

Individuals infected with COVID-19 are also at an increased risk of suffering from heart rhythm disturbances, such as atrial fibrillation. This is shown in a new study at Umeå University, Sweden, which is one of the largest studies of its kind in the world. The researchers were able to show that those who had been […]

Infection with the stomach bacterium Helicobacter pylori could increase the risk of developing Alzheimer’s disease: In people over the age of 50, the risk following a symptomatic infection can be an average of 11 percent higher, and even more about ten years after the infection, at 24 percent greater risk.  These are the findings of […]
