Parkinson’s disease is a progressive neurodegenerative movement disorder caused by the loss of dopamine-producing neurons in the substantia nigra. It presents with tremor, rigidity, bradykinesia, and postural instability. There is no cure, but management significantly controls symptoms and preserves function. Treatment combines medication, surgery, physiotherapy, and addressing non-motor symptoms, with the right combination shifting as the disease progresses.
According to Dr. Gurneet Singh Sawhney, a leading Parkinson’s Surgery specialist at Parkinson’s Surgery in Mumbai, Parkinson’s management isn’t static. The patients who do best are the ones whose treatment plan evolves with the condition rather than staying fixed at what worked five years ago.

What Medications Are Used to Manage Parkinson's Disease?
Pharmacotherapy is the foundation of Parkinson’s management from diagnosis through advanced stages.
Levodopa/carbidopa: Levodopa is the most effective drug for Parkinson’s motor symptoms at every stage. It converts to dopamine in the brain and produces meaningful improvement in tremor, rigidity, and mobility within weeks.
Dopamine agonists: These mimic dopamine and are used alongside levodopa or as initial therapy in younger patients. They carry lower short-term dyskinesia risk and help delay motor complications.
MAO-B and COMT inhibitors: These block enzymes that break down levodopa, extending its effect and reducing off-time between doses. They’re added when motor fluctuations begin.
Motor fluctuation management: As levodopa’s therapeutic window narrows over time, dose timing adjustments and extended-release formulations help. When medication stops managing fluctuations adequately, DBS surgery is the next clinical step.
Medication regimes need regular review. What worked at diagnosis rarely stays optimal.
What Non-Pharmacological Treatments Help Manage Parkinson's?
Physiotherapy, speech therapy, and exercise are evidence-based components of Parkinson’s management that medication doesn’t replace.
Physiotherapy: Regular physiotherapy improves gait, balance, and motor function while reducing fall risk. Three or more hours per week is the evidence-based target for meaningful benefit.
Speech therapy: Hypophonia and dysarthria are common as Parkinson’s progresses. Lee Silverman Voice Treatment produces measurable improvements in vocal volume that medication alone doesn’t address.
Exercise: Regular aerobic exercise independently improves both motor and cognitive function. Walking, cycling, and swimming all have clinical evidence. Consistency is what drives the benefit.
Occupational therapy: Adapting daily tasks and the home environment maintains independence in self-care and reduces caregiver burden as motor symptoms progress. For patients developing motor complications, dyskinesia treatment runs alongside rehabilitation.
Non-pharmacological treatment gets underused. Most patients don’t start physiotherapy until after a fall.
When Does Parkinson's Disease Require Surgical Intervention?
For the right patient at the right time, surgery is the most effective intervention available.
DBS candidacy: DBS is indicated when a patient has good levodopa responsiveness but motor fluctuations and dyskinesias can’t be controlled through medication adjustment. Patient selection is the deciding factor.
Surgical targets: The subthalamic nucleus is the most common target, improving off-period symptoms and reducing dyskinesias and levodopa requirements. The globus pallidus interna is preferred when dyskinesia control is the primary goal.
DBS limitations: Postural instability, freezing of gait, and cognitive symptoms respond poorly to DBS and can occasionally worsen. These need to be addressed with patients before surgery.
Timing: Waiting too long reduces surgical benefit as non-dopaminergic symptoms become dominant. Guidelines now favour earlier DBS in the motor complication phase. For patients managing Parkinson’s alongside other neurological symptoms, the earlier post on early Parkinson’s signs covers what to watch for before motor complications become the dominant concern.
DBS decisions require multidisciplinary evaluation, not a neurosurgical opinion in isolation.
Why Choose Dr. Gurneet Singh Sawhney?
Dr. Gurneet Singh Sawhney is a neurosurgeon with over 18 years of experience in functional neurosurgery, fellowship-trained in DBS and Parkinson’s surgery from Japan. His practice covers the full spectrum from medication optimisation to complex DBS implantation, with a case volume spanning early-stage assessment through advanced surgical cases.
Parkinson’s managed well in the early years means more options later.

Frequently Asked Questions
What is the first-line treatment for Parkinson's disease?
Levodopa combined with carbidopa is the most effective drug for managing Parkinson’s motor symptoms and remains the primary treatment across all disease stages.
When is deep brain stimulation recommended for Parkinson's disease?
DBS is considered when motor fluctuations and dyskinesias are no longer adequately controlled by medication, typically in advanced Parkinson’s with a preserved levodopa response.
Does exercise help manage Parkinson's disease?
Yes. Regular aerobic exercise and physiotherapy improve motor function, gait, and balance in Parkinson’s patients and complement medication-based management.
What are motor fluctuations in Parkinson's disease?
Motor fluctuations are periods of reduced medication effect causing return of Parkinson’s symptoms, typically developing years after starting levodopa as the therapeutic window narrows.
Can Parkinson's disease be cured?
There is no cure for Parkinson’s disease. Management focuses on controlling symptoms, maintaining function, and slowing decline through medication, surgery, and therapy.
