Parkinson’s disease is a neurodegenerative disorder that affects a specific area of the brain — the substantia nigra. It can result in tremors, a slowness of movement known as bradykinesia, uncontrollable muscle contractions known as dystonia, and difficulty with walking and balance.
Deep brain stimulation, or DBS, is a surgical procedure that’s been used to treat Parkinson’s for more than 20 years. Using magnetic resonance imaging, DBS electrodes are inserted into an area of the brain that plays a critical role in movement — either the subthalamic nucleus or the globus pallidus. A small impulse generator, similar to a pacemaker, is also implanted under the skin of the patient’s chest to provide electrical impulses to the electrodes in the brain. The electrical impulses reduce the patient’s symptoms and improves their ability to move.

Arizona State University neuroscientist Bradley Greger has teamed up with Barrow Neurological Institute neurosurgeon Dr. Francisco Ponce to evaluate DBS for its possible use in treating other neurological disorders.
For the study, while the DBS electrodes are being implanted, a second, temporary implant is added to identify what’s happening in the brain during DBS treatment. Directly measuring the effect of DBS on brain activity will aid in extending the use of DBS in other neurological disorders.
Barrow Neurological patient Kimball Rogers and his family agreed to be part of the research. They are sharing their experiences to provide other Parkinson’s patients with information about the value of the procedure and the research.

Neurologist Holly Shill takes notes of the DBS settings with Rogers, after the initial testing and calibrating of his deep brain stimulator implant on Aug. 5, 2019. Rogers felt the effects of each of the four neurostimulators as they pulsed with electrical current. He noticed his tense muscles relaxed, and his tremors diminished.

Seven weeks after his surgery, Rogers sits at home with three of his 20 grandchildren: Kane, Scottie and Eddie. He says the results of the DBS implant are magnificent, while the side effects have been minimal. The recovery from the surgery, though, has taken more time than he expected.

Dr. Francisco Ponce of the Barrow Neurological Institute at Dignity Health St. Joseph's Hospital and Medical Center in Phoenix is one of the nation's leading neurosurgeons involved with deep brain stimulation. The procedure involves implantation of electrodes to a target area deep within the brain that is associated with a disorder.
