How Deep Brain Stimulation Can Restore Your Steady Hands

Lana Laurendeau can’t remember a time when her hands didn’t shake. For years, the shaking made it hard for her to eat without making a mess, drink from a glass without using both hands and put on jewelry. The shaking also made it increasingly hard for her to do her job as a professional hairdresser.
“Essential tremor causes more disability than Parkinson’s, particularly in the hands,” Dr. Goskowski says. “And it is a condition that is not always recognized by physicians, so patients may go undiagnosed.”
Dr. Gostkowski recommended that Ms. Laurendeau undergo a procedure called deep brain stimulation. In deep brain stimulation, surgeons create a small hole in the skull. A neurosurgeon uses computerized mapping and recording to implant an electrode in the precise part of the brain that is misfiring and causing the tremor.
Wires connect the electrodes to a type of pacemaker device that surgeons implant under the skin, such as in the chest below the collarbone. The pacemaker can be easily programmed with a computer via radio signals. Patients use special magnets to turn the device on or off.
Deep brain stimulation also treats Parkinson’s disease, muscle contractions calleddystonia and tremors that can come with multiple sclerosis.
Patients are awake for part of the procedure so that neurosurgeons and intraoperative neurologists can get feedback directly from the patients.
“The surgeon needs to make certain that he or she is optimally targeting the correct part of that patient’s brain,” Dr. Gostkowski says.
Dr. Gostkowski says patients are generally hospitalized for around five days after the surgery and that deep brain stimulation is highly successful for many of his patients.
While the idea of deep brain stimulation scared her, Ms. Laurendeau was determined to regain control of her life. She went through with the procedure in October 2012.
She elected to have the part of her brain that controls her dominant left hand treated first, since just one side of the brain can be operated on at a time. Dr. Gostkowski was in the operating room to help surgeons navigate placement of the electrodes.
Today, the mother of three teenage boys is thrilled that her left hand is tremor-free when she turns on the stimulator. She turns the device off at night via a remote control to preserve the electrode’s battery, which surgeons implanted in her abdomen.
