Deep Brain Stimulation (DBS) has been around for many years and is one of the most common surgical options for the treatment of essential tremor. Recently, a new system has been developed that takes DBS to the next level. The new device actually senses and records the brain signals that cause the symptoms of essential tremor and other movement disorders, allowing researchers the opportunity to see exactly what signals are related to abnormal movements.
Although approved for use in the European Union in January, Medtronic’s Activa PC+S system has not been approved by the Food and Drug Administration (FDA) for use in the United States. However, the new device is currently cleared for study in the U.S. and two patients with advanced Parkinson’s disease have already undergone the surgical implantation of the new device.
The hope is that in the near future, this technology will develop to a level where the device itself will monitor the patient’s brain activity and automatically adjust therapy based on the individual’s needs– just as a pacemaker does for heart patients today. This would be a big advancement in DBS if this technology can be developed. Instead of DBS sending a constant, unchanging signal to cancel out tremor symptoms, the device itself would automatically make adjustments and changes to offer patients optimum benefit.
