Levodopa-induced dyskinesia comes from dopamine arriving in spikes that the brain can no longer absorb, and it shows up as involuntary jerking or writhing. It usually shows up after four to ten years of treatment. By then, Parkinson’s has destroyed most of the neurons that stored dopamine, so the brain can’t hold a dose in reserve. Each tablet arrives as a spike. Roughly four in ten long-term users get it, and relatives tend to notice before the patient does.
According to Dr. Gurneet Singh Sawhney, one of the best neurosurgeon in mumbai, patients assume dyskinesia means the drug has failed, but it’s the brain that has lost its ability to even out each dose.

What Triggers Dyskinesia In The Brain?
So the issue isn’t total dopamine. It’s the peaks.
Dyskinesia treatment begins with a diary of when the movements start and stop relative to each dose.
Who Is Most Likely To Develop It?
Plenty of patients never get it, and nobody can predict which ones.
Duration: The window typically opens four to ten years into treatment, which is why it’s rare in the first couple of years and likelier the longer someone stays on levodopa.
Dose: Higher doses raise the odds, so most neurologists stay at the lowest dose that controls symptoms, even when a bigger one would feel easier in the short term.
Age at onset: Diagnosis in the forties carries the highest risk because those patients take levodopa for decades, often at rising doses as the disease advances.
Surgical options: DBS surgery becomes the next step when dyskinesia stays disabling despite medication changes, and it usually lets the levodopa dose come down as well.
But none of this guarantees anything, and two patients with matching histories can end up miles apart. Biology doesn’t follow the chart.
A closer look at levodopa therapy next to the surgical options shows what each can and can’t do.
Why Choose Dr. Gurneet Singh Sawhney?
Dr. Gurneet Singh Sawhney holds an MCh in Neurosurgery and has more than 18 years in practice, much of it on movement disorders. As Dr. Gurneet Singh Sawhney he trained in functional neurosurgery under Prof. Taira at Tokyo Women’s Medical University, which is where his DBS work comes from.
Each Parkinson’s patient referred for DBS is assessed on their own on/off examinations and symptom diary, then told plainly how much dyskinesia relief and levodopa reduction is realistic. No guesses dressed up as promises.
Frequently Asked Questions
How long does levodopa take to cause dyskinesia?
Usually between four and ten years in.
Is levodopa-induced dyskinesia dangerous?
Not usually, though bad cases make eating and walking hard.
Can lowering the levodopa dose reverse dyskinesia?
Often yes, but stiffness comes back, so it’s a trade.
Does deep brain stimulation help dyskinesia?
It frequently does, and it usually lets patients take less levodopa as well.
