Parkinson disease is now the fastest growing neurological disorder globally.1 An estimated 6.1 million individuals worldwide had a Parkinson disease diagnosis in 2016, 2.4-fold higher than in 1990.1 The most common representation of Parkinson disease continues to be the 1886 sketch by Sir William Richard Gowers, MD, published in his book A Manual of Diseases of the Nervous System (Figure, A).2 Other Parkinson disease images remain largely based on Gowers’ famous sketch: older white men who are frail, hunched forward, and shaking.
