DEEP DIVE · CHAPTER 6
The Movement Machine
The earliest signs of Parkinson’s disease show up in the nose and the bowel, about a decade before the hand. A medication nobody stopped can also cause the same slow, stiff picture.
I taught the clean two-path model of movement for years, and it turned out to be too simple. Parkinson’s does not start in the hand — it starts in the nose and the bowel, a decade early. And the second most common cause of that same slow, stiff picture is not a disease at all. It is a prescription somebody forgot to stop.

Frequently asked questions
What are the earliest signs of Parkinson’s disease?
The earliest signs of Parkinson’s disease show up in the nose and the bowel, about a decade before anything shows in the hand. The slow, stiff picture most people associate with the disease comes later. Chapter 6 explains why the clean two-path model of movement, which the author taught for years, turned out to be too simple to explain that early stretch.
Does Parkinson’s start with a tremor in the hand?
No. Parkinson’s does not start in the hand. It starts in the nose and the bowel, about a decade before the hand is involved. That long head start is why the early picture is easy to miss when a person and their doctor are watching only for changes in movement. The hand is where the disease finally becomes obvious, not where it begins.
Can a medication cause Parkinson’s-like symptoms?
Yes. The second most common cause of the same slow, stiff picture is not a disease at all. It is a prescription somebody forgot to stop. If you or a family member has become slow and stiff, bring a full list of current medications to the doctor, including ones started years ago that nobody has looked at since.
