When Kathleen Prezocki’s essential tremor progressed to the point that she could no longer do many of the things she enjoyed, she knew it was time to take action. “It was affecting me in eating, in writing and in speech. The medicine was not allowing me to control the symptoms anymore,” Prezocki said. Her doctors at UofL Physicians suggested deep brain stimulation (DBS) therapy, in which a surgeon implants in the brain a wire lead that is attached to a battery controller, similar to a pacemaker for the heart. The lead provides electrical stimulation to a precise point in the brain to mitigate the tremor. DBS technology has improved since it was first available nearly 20 years ago, and devices now used at UofL allow more precise control over the stimulation, avoiding side effects, and feature more intuitive controllers.
