19th century In Parkinson's disease

In 1817 James Parkinson published his essay reporting 6 cases of paralysis agitans. An Essay on the Shaking Palsy described the characteristic resting tremor, abnormal posture and gait, paralysis and diminished muscle strength, and the way that the disease progresses over time. He also acknowledged the contributions of many of the previously mentioned authors to the understanding of PD. Although the article was later considered the seminal work on the disease, it received little attention over the forty years that followed. Nevertheless, early neurologists who made further additions to the knowledge of the disease include Trousseau, Gowers, Kinnier Wilson and Erb, and most notably Charcot, whose studies between 1868 and 1881 were a landmark in the understanding of the disease. Among other advances he made the distinction between rigidity, weakness and bradykinesia. He also championed the renaming of the disease in honor of James Parkinson.
