Two hundred years ago at the age of 62, James Parkinson wrote a 66 page treatise entitled An Essay on the Shaking Palsy. As a young apothecary Parkinson had attended a course of evening lectures given by the eminent surgeon-anatomist, John Hunter and taken copious shorthand notes.
The muscles of respiration were so affected, that respiration was with difficulty effected; but in sleep the vibratory motions of the muscles ceased, and the respiration was performed more equably: any endeavour of the will to alter these morbid actions increased them. We will now never know what stimulated Parkinson to write his medical classic but perhaps the subliminal influence of his hero and fellow geologist was a factor.
Parkinson defined the shaking palsy as a nervous disorder characterized by a trembling of the limbs at rest, lessened muscular power and a stooped posture associated with a propulsive, festinant gait.
Chapter 1 of The Essay concludes with six clinical vignettes.

All the cases were men who had noticed the first signs of the malady between the age of 50 and 65 years. Parkinson emphasizes that the weakness is specific and differs from that seen in other forms of palsy.
The fingers cannot be disposed of in the proposed directions, and applied with certainty to any proposed point. The tremor is coarse and on occasions violent and is always maximal when the limb is at rest. In Case III it affects the head, which nowadays would raise suspicion of an essential or dystonic tremor. He notes that the tremor usually begins in one limb and then spreads to involve the other limbs over several years.
Case VI informs Parkinson that he is able to interrupt the interminable shaking for a few minutes by a brief sudden voluntary movement of the affected arm. In about three years afterwards the right arm became affected in a similar manner: and soon after the convulsive motions affected the whole body, and began to interrupt the speech. In about three years from that time the legs became affected. Parkinson clearly describes the characteristic festinant gait of the fully established case but there is no clear description of either start hesitation or freezing blocking of gait.
It being asked if whilst walking he felt much apprehension from the difficulty of raising his feet, if he saw a rising pebble in his path? John Elliotson, soon to become the Professor of Medicine at University College Hospital, credited Parkinson with nearly all of his knowledge on the subject in a series of case reports purported to represent cases of paralysis agitans in the Lancet in and It was almost as if his observations came as no surprise to anyone, yet nobody before him had put two and two together.
Humboldt believed he was describing the motor deficits of senility whereas Parkinson considered the shaking palsy to be a medical disorder rather than an extreme version of normal ageing. This observation underpinned the modern definition of bradykinesia progressive reduction in speed and amplitude after 20 s of sequential finger taps Gibb and Lees, They can be identified from afar; you do not need a medical history. In the forefront of the picture and in the enlarged inset is a man who may have the shaking palsy.
The face wears a peculiarly stolid expression. In Chapter IV of the Essay Parkinson cautiously proposes the possible site of damage leading to the symptoms of the shaking palsy. More recently syndromes of dementia, visual pseudo-hallucinations and primary cardiovascular autonomic failure have all been associated with Lewy body and Lewy neurite pathology.
The development of more precise clinical diagnostic criteria in the s and 90s capable of a higher degree of correlation with typical pathological findings derives from a determination to preserve the shaking palsy as a clinicopathological entity within the growing quantity of neuropathologically distinct parkinsonian syndromes Gibb and Lees, These individuals fulfil pathological criteria for the diagnosis but differ substantially in their clinical presentation from the shaking palsy.
They present at an older age with axial and bulbar symptoms and early falls in the first 5 years. They have a more rapid deterioration.
Some have executive and visuo-spatial dysfunction at presentation and many go on to develop early autonomic dysfunction including orthostatic hypotension. Tremor is not prominent but if looked for carefully may be present in a finger or in the lips or chin. The discovery in of severe depletion of dopamine in the corpus striatum stemming from new anatomical and chemical techniques was the sort of advance that Parkinson had hoped for Ehringer and Hornykiewicz, The shaking palsy could now be classified as a striatal dopamine deficiency and even as a neurohumoral disorder.
The autosomal dominant forms of parkinsonism, including that resulting from the commoner mutation of dardarin, are clinically indistinguishable from the shaking palsy. As a result, REM sleep disorder, reduced sense of smell, constipation and depression have been proposed as risk factors for the shaking palsy.
It seems likely that the Lewy body is a protective mechanism created to shield the neuron from further toxic insults. A logician would have started by defining what he meant by disease as a whole and then produced individual diseases by sub-dividing the territory whose boundaries he had thus defined.
Medicine … proceeded the other way and started with individual diseases.
