Parkinson’s disease is a progressive neurological condition that affects the part of the brain responsible for movement. It causes symptoms like tremors, stiffness, slow movements, and balance problems. Because there is no single test to confirm it, diagnosing Parkinson’s requires careful medical evaluation by a neurologist.
Step 1: Detailed Medical History
The diagnosis begins with a complete discussion of your medical and family history.
Your neurologist will ask about:
When your symptoms started and how they have progressed
Any history of exposure to toxins or head injuries
Medications you are currently taking
Family members with Parkinson’s or related disorders
Step 2: Neurological Examination
A physical and neurological exam is the most important part of diagnosis.
The doctor checks for:
Tremors (shaking of hands or fingers at rest)
Bradykinesia (slowness of movement)
Muscle stiffness or rigidity
Postural instability (balance problems)
Changes in facial expression, handwriting, or speech
Step 3: Supportive Diagnostic Tests
While no lab test can confirm Parkinson’s directly, some tests help rule out other conditions:
MRI or CT Scan – To exclude brain tumor or stroke
DaTscan (Dopamine Transporter Scan) – Measures dopamine activity in the brain
Blood Tests – To eliminate metabolic or thyroid disorders
Step 4: Levodopa Response Test
In many cases, doctors may prescribe a trial of Levodopa (L-Dopa).
If your symptoms significantly improve after taking the medication, it supports the diagnosis of Parkinson’s disease.
Step 5: Continuous Monitoring
Parkinson’s develops gradually, so doctors often monitor symptoms over time. Regular follow-ups help confirm the diagnosis and adjust treatment as needed.
