My sister spent the past year in severe distress over an undiagnosed movement disorder. They had diagnosed her with conversion disorder and during her visit to Arizona from Kansas, I became so distressed watching her attacks that I took a referral from a friend who goes to Dr. Evidente and emailed last minute to see if she could see him during her 1 week trip. He had a cancellation and spend at least an hour (probably more) hearing her story, doing a thorough test and then inducing an attack. He then showed us videos of the disorder he felt she had and booked 4 hours of tests a couple of days later. Her insurance wouldn't cover it and he gave us discounted rates to pay cash. The technicians and nurses were excellent, and the front desk excellent at explaining the billing process. By Friday he was almost certain he had a diagnosis but is running a genetic test to be sure. This doctor was an absolute God-send and I highly recommend a visit to him if you have an undiagnosed movement disorder. He is very qualified, extremely experienced and seems to have devoted his life to treating patients. While we were in the waiting room there were people arriving who had flown in for their annual visit to see him. I am grateful God lead us in his direction. Thank you Dr. E for devoting your life to this cause.
