Dyskinesia is involuntary, writhing or dance-like movement of the limbs, trunk or face that develops after years of levodopa therapy in Parkinson’s disease. It is a side effect of the treatment, not a symptom of the disease itself. It can range from mild movements only you notice to severe episodes that cause exhaustion, weight loss and injury. It’s hard to manage because lowering levodopa worsens motor symptoms, while raising it worsens dyskinesia.
According to Dr. Gurneet Singh Sawhney, a neurosurgeon in Mumbai with specialised training in movement disorder surgery, “dyskinesia forces a difficult trade-off where the same drug controlling tremor and rigidity is also driving involuntary movements, and that balance can’t be managed without understanding the patient’s full disease trajectory.”

What Are the Types and Risk Factors for Dyskinesia?
Numbness fades within a few hours, and a tooth too damaged to hold a crown may need dental implants instead. Rare, but real.
How Is Dyskinesia Treated and When Is Surgery Considered?
Treatment depends on severity, how well motor symptoms are controlled and the patient’s functional goals.
- Dose adjustment: Smaller, more frequent doses or controlled-release forms flatten the levodopa peaks that drive dyskinesia.
- Amantadine: It reduces involuntary movements by blocking NMDA receptors, and extended-release forms are used for dyskinesia.
- Deep brain stimulation: For severe cases, deep brain stimulation of the subthalamic nucleus or globus pallidus interna allows a major levodopa reduction, which treats the cause, not just the movements.
- Stress and lifestyle: Stress worsens dyskinesia, and regular activity, sleep and stress reduction ease it, though they don’t change the underlying mechanism.
DBS doesn’t just reduce dyskinesia. It often restores the therapeutic window of levodopa to a width that makes motor control predictable again, which goes further than the usual tips to manage dyskinesia in Parkinson’s disease.
Why Choose Dr. Gurneet Singh Sawhney?
Dr. Gurneet Singh Sawhney holds MBBS, MS (General Surgery), and MCh (Neurosurgery) qualifications, stood first in the MCh university examination, and completed fellowships in Functional Neurosurgery and Epilepsy Surgery in Japan. With 18 years of overall experience, he manages the full dyskinesia-Parkinson’s spectrum including medication optimisation, DBS candidacy assessment, and post-operative programming. He is a member of the Indian Society of Stereotaxy and Functional Neurosurgery (ISSFN).
His patients with levodopa-induced dyskinesia treated through DBS consistently report reduced involuntary movement frequency, restored medication control, and return to daily independence. That’s the outcome measure that matters.
Frequently Asked Questions
Is dyskinesia the same as Parkinson's disease tremor?
No, tremor is a Parkinson’s symptom; dyskinesia is a side effect of levodopa medication.
Can dyskinesia be reversed without surgery?
Mild dyskinesia often responds to dose adjustment; severe cases typically require amantadine or DBS.
Does everyone on levodopa develop dyskinesia?
No, but risk rises with higher dose, longer duration, and younger age at Parkinson’s onset.
Does deep brain stimulation cure dyskinesia permanently?
DBS significantly reduces dyskinesia by enabling lower levodopa doses but isn’t classified as a cure.
