Carly Simon reveals the common condition that masked her Parkinson’s diagnosis
While tremor is often considered a hallmark symptom, Schwartz cautioned that it isn’t always present. “About a third of individuals with Parkinson’s disease do not have a tremor,” he said. “That’s when the diagnosis becomes more challenging.”
“In Parkinson’s disease, dexterity becomes compromised because of slowness and stiffness,” the expert added. “In arthritis, it’s more of a mechanical issue, where the joints don’t allow full range of motion.”
How is Parkinson’s diagnosed?
The two conditions can be especially difficult to distinguish because both are largely diagnosed based on a patient’s symptoms and physical examination rather than one definitive test, according to Schwartz.

There is no single blood test or imaging scan that can definitively confirm Parkinson’s, as “very few things in medicine are 100%,” he said.
However, newer diagnostic tools have emerged, including specialized imaging and skin biopsy testing. “We’re still learning,” the neurologist said, adding that a blood test may be on the horizon.

For now, diagnoses are made based on the following factors, per the National Institute of Neurological Disorders and Stroke (NINDS).
- A detailed medical history, including the type and timeline of symptoms
- A neurological exam that identifies telltale symptoms such as tremor, slowed movement, muscle stiffness, gait changes and balance problems
- A physical exam to assess movement, coordination, reflexes and other neurological functions
- The patient’s response to Parkinson’s medications
- Additional tests to eliminate other conditions

Schwartz emphasized that early diagnostic uncertainty is not uncommon. “It’s not unusual for there to be misdiagnoses,” he said. “Sometimes seeing a patient over time helps — eventually the disease declares itself, and then it’s easier to make the diagnosis.”
Anyone experiencing persistent walking difficulties, stiffness or other symptoms that don’t seem fully explained by arthritis should discuss them with a healthcare provider, who can determine whether a neurological evaluation is appropriate.
