Deep brain stimulation (DBS) has become the standard treatment for movement disorders, but there are still unanswered questions about the pathomechanisms of dystonia and the mechanisms of DBS on neuronal circuitry. Lack of knowledge limits therapeutic effect and makes it difficult to predict outcomes for individual dystonia patients. Electrophysiological biomarkers may offer a promising option for personalized DBS treatment.
Deep brain stimulation (DBS), a treatment for modulating the abnormal central neuronal circuitry, has become the standard of care nowadays and is sometimes the only option to reduce symptoms of movement disorders such as dystonia. However, on the one hand, there are still open questions regarding the pathomechanisms of dystonia and, on the other hand, the mechanisms of DBS on neuronal circuitry. That lack of knowledge limits the therapeutic effect and makes it hard to predict the outcome of DBS for individual dystonia patients. Finding electrophysiological biomarkers seems to be a promising option to enable adapted individualised DBS treatment. However, biomarker search studies cannot be conducted on patients on a large scale and experimental approaches with animal models of dystonia are needed. In this review, physiological findings of deep brain stimulation studies in humans and animal models of dystonia are summarised and the current pathophysiological concepts of dystonia are discussed.
