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.
