What is the title of Dr. Parkinson's manuscript?

The title of Dr. Parkinson's manuscript is "An Essay On The Shaking Palsy." This work, published in 1817, is significant because it was the first detailed medical case study of what we now know as Parkinson's disease. In it, Dr. James Parkinson provided a comprehensive description of the symptoms and progression of the disease, focusing on the shaking and other motor impairments that characterize the condition. His observations laid the groundwork for future research and understanding of Parkinson's disease, making his manuscript a pivotal contribution to neurology. The other titles listed reflect modern interpretations and discussions surrounding the disease but do not pertain to Dr. Parkinson's original manuscript, which remains widely recognized for its historical and clinical significance.
