Parkinson's Disease and Movement Disorders Program

At UC Irvine Health, we specialize in the diagnosis and treatment of movement disorders. Our specialists combine state-of-the-art clinical care and advanced technology in a warm and reassuring environment.

Our physicians are board-certified and fellowship-trained in treating Parkinson's disease and other movement disorders, including Huntington's disease and dystonia. We work in collaboration with physical therapists and nutrition counselors to personalize each patient's care.

Our patients also benefit from our leading-edge clinical research and access to the latest technologies. The Parkinson's Disease and Movement Disorders team belongs to several national and international research consortiums on movement disorders, including: the Parkinson’s Study Group, the Huntington’s Study Group and the Dystonia Study Group.
