Can This New NonInvasive Brain Stimulation Cure Parkinsons

first_img MIT researchers developed a new form of non-invasive deep brain stimulation that promises to be less risky, less expensive, and more accessible to patients.In partnership with investigators at Beth Israel Deaconess Medical Center (MIDMC) and the IT’IS Foundation, MIT hopes this technology can treat people with Parkinson’s disease, obsessive-compulsive disorder, epilepsy, and depression, among other conditions (like autism).“Traditional deep brain stimulation requires opening the skull and implanting an electrode, which can have complications,” Ed Boyden, associate professor of biological engineering and brain and cognitive sciences at MIT said in a statement.“Only a small number of people,” he added, can do this kind of neurosurgery, which requires implanting electrodes in the brain. Those used to treat Parkinson’s disease, for instance, are usually placed in the subthalamic nucleus—i.e. “deep within the brain.”But while the procedure can improve symptoms, surgery is incredibly risky and can lead to brain hemorrhage and infection.Instead, MIT analysts are using temporal interference to deliver stimulation via electrodes placed on the scalp.As described by the Institute, two high-frequency electrical currents intersect deep within the brain, generating a low-frequency current inside neurons—which can be used to drive neurons’ electrical activity. The high-frequency current, meanwhile, passes through with no effect.The researcher retains complete control over size and location of stimulation and can steer the system without moving electrodes, allowing for adoption in therapeutic and scientific operations.So far, testing has been conducted only with mice; there is no word on if or when this project will expand to include human patients. Still, Li-Huei Tsai, director of MIT’s Picower Institute for Learning and Memory, remains optimistic.“I think it’s very exciting because Parkinson’s disease and other movement disorders seem to originate from a very particular region of the brain, and if you can target that, you have the potential to reverse it,” she said.
