Scientists are developing tiny particles made from natural sugar-based compounds that can deliver medicine to the brain while reducing inflammation caused by neurodegenerative diseases like Alzheimer’s and Parkinson’s. These nanoparticles are special because they can cross the protective barrier surrounding the brain and carry therapeutic compounds directly to where they’re needed. The natural polysaccharides used to make these particles have built-in anti-inflammatory properties, making them safer and more effective than traditional approaches. This innovative technology shows promise for treating currently difficult-to-manage brain diseases.
