FAQ: What is Deep Brain Stimulation (DBS), and how can I help someone with Tourette’s Syndrome ?
Answer: DBS is a relatively new procedure that utilizes an implantable electrode to alter the activity of brain circuitry.
The procedure is FDA approved for Parkinson’s disease, essential tremor, dystonia and OCD, and currently utilized for patients who have not responded to standard medical or behavioral therapy, and who have no cognitive difficulties or “minimal” cognitive (thinking issues) dysfunction may be appropriate candidates.
There are two essential components to the hardware involved in DBS, the implantable electrodes and the programmable pulse generator. The DBS electrode is implanted into a specific target within the brain and the pulse generator, or neurostimulator, is implanted under the skin just below the collar bone (or in the abdomen for women); an extension cable passes under the skin and connects the electrode to the neurostimulator. The DBS electrode has four contact points, the sites through which electricity is delivered. Active contacts can be selected by computer and multiple settings can be adjusted for individual patient needs. The settings can be adjusted for different pulse widths (how long each pulse of stimulation lasts), frequencies (how many pulses are delivered each second), and amplitudes of stimulation (how much voltage is delivered).
DBS has the potential to “neuromodulate” abnormal communication that occur deep within the brains of people with TS. So far researchers have probed into several areas in the brain of people with TS (the centromedian thalamus, the internal globus pallidus, the external globus pallidus, and the anterior limb of the internal capsule) and they have had mixed success. The best target for “neuromodulation” has yet to be determined, however it does appear that DBS has positive results in some patients.
