Non-invasive neuromodulation approaches can prevent invasive surgery in Parkinson s patients From optogenetics to sonogenetics to magnetognetics, scientists around the world are investigating new techniques to treat Parkinson s disease without the need for invasive surgery. There is still no treatment that can reverse the effects of Parkinson s disease, a condition estimated to affect 10 million people worldwide. As life expectancy increases, the number of people suffering from this disease is set to rise in the future, making the need for effective treatment a priority. Doctors prescribe oral medication to alleviate the main symptoms and, for a few patients, use deep brain stimulation. The electrodes stimulate the affected areas and relieve the reactions induced by the disease such as tremor or rigidity. ....
Magnetic nanoparticles guide neurite growth in dopaminergic cells Magnetic nanoparticles raise hopes of treatments for Parkinson’s. One reason why nerve damage in the brain cannot regenerate easily is that the neurites do not know in which direction they should grow. A team of researchers from Ruhr-Universität Bochum (RUB), Sorbonne University Paris, and the Technische Universität Braunschweig is now working on showing them the direction using magnetic nanoparticles. The team led by Professor Rolf Heumann, Senior Researcher for Molecular Neurobiochemistry at RUB, is hoping that this will allow the effects of neurodegenerative diseases such as Parkinson s to be alleviated over the long term. The results of the work were published on 31 December 2020 in the journal ....
