Because there is no definitive blood test or brain scan to confirm a diagnosis of movement disorders like Parkinson's disease, neurologists rely on visual examination to diagnose and track these diseases. But despite an increasingly sophisticated understanding of movement disorders at the cellular level, being able to detect very subtle visual cues -- and even better operate a video camera -- can make a big difference in the early diagnosis of movement disorders.
This shortcoming led two Rush University Medical Center neurologists to publish a set of videotaping guidelines Video Protocols and Techniques for Movement Disorders via Oxford University Press. While only neurologists will find these video protocols useful, they may provide an interesting story angle. Just last month there was speculation that former President Clinton had Parkinson's because his hand trembled during a speech. He does not, but the Scottish Actor Billy Connelly was diagnosed with the disease in 2014 after a physician attending a play recognized signs.
