Deep brain stimulation is a way to inactivate parts of the brain that cause Parkinsons disease and its associated symptoms without purposefully destroying the brain. In deep brain stimulation, electrodes are placed in the thalamus (for essential tremor and multiple sclerosis) or in the globus pallidus .
In deep brain stimulation electrodes are connected by wires to a type of pacemaker device (called an impulse generator, or IPG) implanted under the skin of the chest, below the collarbone. Once activated, the device sends continuous electrical pulses to the target areas in the brain, blocking the impulses that cause tremors. This has the same effect as thalamotomy or pallidotomy surgeries without actually destroying parts of the brain.
The IPG can easily be programmed using a computer that sends radio signals to the device. Patients are given special magnets so they can externally turn the IPG on or off.
Depending on use, the stimulators may last three to five years. IPG replacement procedure is relatively simple.
The stimulation can be turned on or off by the patient with a hand-held magnet or an access control device.
How Is DBS Performed ?
Patients who are having stimulators placed on both sides of the brain will have their surgery divided into two parts. Most people with Parkinson's disease will require the surgery be done on both sides of the brain. During the first surgery, the electrodes are placed into the brain, but left unconnected.
There are several ways in which the electrodes are placed into the target areas of the brain. First these areas must be located. One way to locate the target areas is to rely only on a computed tomography (CT) or magnetic resonance imaging (MRI) scan. While some surgeons stop there, others use an electrode recording technique to map and target the specific areas that they will need to reach.
Once the correct location is identified, the permanent electrodes are implanted. The loose ends are placed underneath the skin of the head and the incision is closed with sutures. The patient receives general anesthesia for the placement of the impulse generator in the chest and the positioning of extension wires that connect the electrodes to the impulse generators. It may take a few weeks until the simulators and medications are adjusted sufficiently for patients receive adequate symptom relief. But, DBS causes very few side effects.
