There is no validated checklist or single test that can diagnose Parkinson's disease. Use this checklist to track symptoms, prepare questions, and verify what the examination and optional tests can actually establish. Parkinson's is diagnosed from a person's history and a skilled neurological examination, according to the National Institute on Aging. Your notes cannot confirm the condition, but they can give the clinician clearer evidence to assess.

Track symptoms in a useful way
Record when each symptom began and how it has changed. Track movement symptoms as well as changes that may affect safety, communication, comfort, or independence.
For each symptom, note its frequency, time of day, triggers, relievers, and effect on daily life. Add medication timing when relevant. If an intermittent movement does not reliably appear during appointments, record a short video for the care team.
- Tremor at rest or during activity
- Slowness, stiffness, or difficulty starting movement
- Walking, turning, posture, balance, or falls
- Facial expression, voice, or swallowing
- Mood, thinking, sleep, dizziness, constipation, or pain
Prepare your health and medication history
Write a brief timeline rather than relying on memory during the visit. Include symptom onset, progression, medical conditions, family history, and relevant lifestyle details because illnesses and medicines can resemble Parkinson's symptoms.
Bring every prescription medicine, over-the-counter product, and supplement. For each one, list: Do not omit a product because it seems unrelated. A complete medication record helps the clinician consider alternative explanations and interpret symptom timing.

Know what the examination should cover
The clinician should assess limb speed and coordination, muscle tone, resting and action tremor, walking, turning, posture, and balance. The examination may also include facial expression, speech, and how easily you rise or begin moving. Clinicians first decide whether the signs form parkinsonism, a movement pattern centered on bradykinesia—unusually slow movement—and assessed alongside resting tremor and rigidity.
The Movement Disorder Society's diagnostic standard then weighs findings that support Parkinson's against exclusion criteria and warning signs for other conditions. One isolated symptom does not settle the diagnosis. The pattern, progression, history, and examination findings must make sense together.
Ask questions that clarify the decision
Ask the clinician to explain the working diagnosis and the evidence behind it. Useful questions include: Take notes or bring a care partner who can record the answers and add observations. Before leaving, confirm the next step, who will arrange it, and what changes you should document before follow-up.
- What diagnosis are you considering?
- Which findings support it?
- What other conditions or medication effects are you excluding?
- Is the diagnosis clear now, or will it require follow-up?
- Would a test change the diagnosis, treatment, or monitoring plan?
Verify what additional tests can show
MRI and blood work may help rule out other explanations. A DaTscan may clarify some uncertain cases, but it does not provide a stand-alone answer: a positive result cannot distinguish Parkinson's from several atypical parkinsonian disorders, while a negative result does not exclude early Parkinson's, according to the Parkinson's Foundation. An alpha-synuclein skin biopsy may support evaluation when the case remains unclear.
It cannot diagnose Parkinson's by itself or identify which synuclein-related condition is present. Ask what specific uncertainty a proposed test addresses and whether its result would change care. If the diagnosis remains unclear, ask whether evaluation by a movement-disorder specialist would add useful expertise.
