Being diagnosed with Parkinson’s disease can be a shocking, despair-inducing experience. But UCI Health neurologist Dr. Claire Henchcliffe believes knowledge is power. “Knowing more about what’s happening to you allows you to seek as much information as you wish, and to look for opportunities for optimal treatment now and in the future, including participating in clinical trials, if desired,” she recently advised. Parkinson’s disease is the fastest-growing neurological disorder in the world, affecting an estimated 10 million people. Nearly 90,000 U.S. cases are diagnosed each year.
