Deep brain stimulation advance extends relief from Parkinson's symptoms

• by Nick Lavars

A new study has marked a significant step forward for the technology, with researchers having upped the precision to target specific types of cells, which sees the effects of the therapy last several times as long in animal models. Deep brain stimulation for Parkinson's involves surgically implanting tiny wires into targeted areas of the brain, delivering mild electrical impulses to the region responsible for movement. This has been approved as a treatment for tremors associated with Parkinson's since 1997, and recent studies have shown how it can boost dopamine levels and potentially slow progression of the disease. But one aspect scientists would like to improve upon with regard to motor symptoms is how long the effects last for, with recipients relying on continuous stimulation to prevent ongoing tremors.
