Like the spinal cord stimulation system, which is implanted near the spine and sends electrical impulses to the nerves to disrupt pain, deep brain stimulation involves an implantation process as well. First, an electrode is implanted within the brain to reach the targeted location of faulty impulses or tremors. Next, electrodes are attached to wires that connect to an internal pulse generator (IPG). The IPG is secured in the patient’s chest, like a pacemaker device. An external handheld magnet or remote control are used to switch the IPG on or off as needed. Deep brain stimulation is effective in treating tremors and involuntary muscle movements caused by Parkinson’s disease, multiple sclerosis, and dystonia.
