Deep Brain Stimulation

Deep brain stimulation (DBS) is a surgical technique to implant a device that transmits or sends electrical signals to brain areas responsible for body movement. Electrodes are implanted deep in the brain depending upon the symptoms being treated and are connected to a stimulator device. The electrodes are implanted on both the left and right sides of the brain through small holes made at the top of the skull.

The electrodes are linked together by lengthy wires which travel beneath the skin and below the neck to a battery powered stimulator beneath the skin of the chest. After turning on, the stimulator transmits or sends electrical pulses to block the faulty nerve signals which are causing tremors, rigidity, and other symptoms. Similar to a heart pacemaker, a neuro-stimulator uses electric pulses to control brain activity.

Deep brain stimulation (DBS) can help lower the symptoms of tremor, slowness, stiffness, and walking issues caused by Parkinson's disease, dystonia, or essential tremor. Successful Deep brain stimulation permits people to potentially lower their medications and improve their quality of life.

The patient uses a handheld controller to turn the Deep brain stimulation (DBS) system on and off. The primary care physician programs the stimulator settings with a wireless device. The stimulation settings could be adjusted as a patient's condition changes over time. Unlike other surgeries, like pallidotomy or thalamotomy, Deep brain stimulation (DBS) doesn’t damage the brain tissue. Therefore, if better treatments develop in the future, the Deep brain stimulation (DBS) procedure could be reversed.

A Deep brain stimulation (DBS) system has 3 parts that are implanted inside the body:

  • Neurostimulator – A programmable battery-powered pacemaker device which generates electric pulses. It is implanted under the skin of the chest below the collarbone or in the abdomen.
  • Lead – A coated wire with a number of electrodes at the tip which delivers electric pulses to the brain tissue. It is implanted inside the brain and joins to an extension wire through a tiny hole in the skull.
  • Extension – An insulated wire which joins the lead to the neuro-stimulator. It is implanted underneath the skin and runs from the scalp, behind the ear, down the neck, and to the chest.


Deep brain stimulation (DBS) could help treat many of the symptoms caused by the following movement disorders:

  • Parkinson's disease - Tremor, rigidity, and slowness of movement caused by the death of dopamine-producing nerve cells responsible for relaying messages which control body movement.
  • Essential tremor - Involuntary rhythmic tremors of the hands and arms, happening both at rest and during purposeful movement. Also might affect the head in a "no-no" motion.
  • Dystonia - Involuntary movements and prolonged muscle contraction, leading to twisting or writhing body motions, tremors, and abnormal posture. Might include the entire body, or only an isolated region. Spasms could usually be suppressed by "sensory tricks," like touching the face, eyebrows, or hands.
