15 Frequently Asked Questions : Parkinson's Treatment and DBS Surgery in India for Zambian Patients

Q1 · Why do Zambian patients consider Parkinson's Treatment and DBS Surgery in India?

Zambian patients may consider India when Parkinson's symptoms become difficult to control despite appropriate medical treatment.

Potential reasons include:

• Specialist movement-disorder evaluation
• Advanced Parkinson's medication management
• DBS suitability assessment
• Functional neurosurgery
• STN DBS
• GPi DBS
• Selected tremor-focused DBS
• Advanced imaging and surgical planning
• Multidisciplinary neurological care
• DBS programming and follow-up
• Neurorehabilitation
• Access to newer DBS technologies at selected centres

DBS is generally considered for appropriately selected patients with medication-related motor fluctuations, disabling dyskinesias and/or tremor that is not adequately controlled with medication.

India also has established specialist movement-disorder centres, and a 2026 Apollo Hospitals Chennai report documented India's first clinical activation of adaptive DBS for Parkinson's disease.

Q2 · How much does Parkinson's Treatment and DBS Surgery cost in India for Zambian patients?

The total cost depends on whether the patient requires medical management, DBS evaluation or implantation. For surgery, the device, electrodes, hospitalisation, programming and follow-up can substantially affect the final quotation.

Planning exchange rates: US$1 ≈ ZMW 19.5 US$1 ≈ INR 96

Important: These are planning estimates rather than fixed packages. The final cost can vary according to the DBS system selected, electrodes, battery type, imaging, hospital category, surgical complexity, programming sessions and follow-up requirements.

The Indian government has recognised DBS as a treatment available through CGHS-empanelled hospitals, with DBS implants and batteries separately addressed within its medical-implant framework.

Travel, accommodation, visa, food and local transportation are generally additional expenses.

Q3 · Which Indian cities can Zambian patients consider?

NIMHANS Bengaluru has a dedicated Parkinson's disease and movement-disorders service with DBS, neuropsychological assessment, gait and balance assessment, speech therapy and neurorehabilitation support.

Q4 · Which hospitals in India can Zambian patients consider?

The following hospitals can be considered for specialist evaluation.

Important: Not every hospital listed necessarily offers DBS or every DBS device. The specific movement-disorder programme, functional neurosurgery service and implant availability should be confirmed before travel.

Apollo Hospitals Chennai has reported advanced Parkinson's and DBS services, including clinical activation of adaptive DBS in March 2026.

Jaslok Hospital describes a long-standing DBS programme involving stereotactic planning, MRI and microelectrode recording.

NIMHANS Bengaluru also provides DBS and multidisciplinary movement-disorder assessment.

Q5 · What is Parkinson's disease and what types of treatment are available?

Parkinson's disease affects movement-control pathways in the brain and can produce symptoms such as:

• Tremor
• Rigidity
• Slowness of movement
• Reduced automatic movements
• Walking difficulties
• Balance problems
• Speech difficulties
• Swallowing problems

Medical Treatment

Depending on the patient, treatment may include:

• Levodopa/carbidopa
• Dopamine agonists
• MAO-B inhibitors
• Other medicines for individual symptoms

Rehabilitation

Treatment can also include:

• Physiotherapy
• Occupational therapy
• Speech and swallowing therapy
• Gait and balance training
• Exercise programmes
• Fall-prevention strategies

Advanced Treatment

For appropriately selected patients, advanced treatment may include:

• Deep Brain Stimulation
• STN DBS
• GPi DBS
• Selected tremor-target DBS
• Rechargeable DBS
• Sensing-enabled DBS
• Adaptive DBS at selected centres

NIMHANS identifies STN, GPi and VIM as DBS targets used for different movement-disorder indications.

Q6 · What are the potential benefits of DBS Surgery?

For appropriately selected Parkinson's patients, DBS can help control certain motor symptoms.

Potential benefits include:

• Reduction in tremor
• Improvement in rigidity
• Improvement in bradykinesia
• Reduction in motor fluctuations
• Reduction in medication-related dyskinesia
• Increased useful "ON" time
• Potential reduction in medication requirements
• Programmable stimulation
• Long-term adjustment of stimulation settings

NIMHANS notes that DBS can benefit Parkinson's motor symptoms including tremor, rigidity and bradykinesia and can reduce motor fluctuations and medication-induced dyskinesia in suitable patients.

DBS does not cure Parkinson's disease and may not improve every symptom. In particular, symptoms such as significant cognitive problems, some balance problems and other non-motor symptoms may not respond to DBS.

Q7 · Who may be suitable for DBS Surgery?

DBS is considered only after detailed specialist assessment.

Factors that may support consideration include:

• Confirmed Parkinson's disease
• Sufficient duration of disease to establish the diagnosis
• Good response to levodopa
• Significant motor fluctuations
• Disabling dyskinesias
• Tremor not adequately controlled by medication
• Symptoms substantially affecting quality of life
• Inadequate control despite appropriate medication

The assessment also considers:

• Cognitive function
• Psychiatric status
• General medical condition
• MRI findings
• Surgical risk
• Patient expectations
• Family and social support

SCTIMST describes a rigorous selection process and notes that significant cognitive or psychiatric problems, severe drug-resistant balance/gait problems and certain serious medical conditions can affect DBS suitability.

Q8 · What medical documents should Zambian patients send before travelling?

Patients should ideally provide:

• Neurologist's diagnosis
• Complete Parkinson's history
• Current medication list
• Previous Parkinson's medications
• Medication doses and timings
• Details of medication response
• Wearing-off history
• Dyskinesia history
• Tremor history
• MRI brain
• CT scan where available
• Previous neurological reports
• Previous hospital records
• Blood-test reports
• Previous surgical history
• Cognitive assessment where available
• Psychiatric evaluation where relevant
• Physiotherapy reports
• Relevant symptom videos where appropriate

Patients should provide the actual MRI/CT images, rather than only the written reports.

A specialist team may perform additional medication-response testing, neuropsychological assessment and imaging before recommending DBS.

Q9 · How does Parkinson's Treatment and DBS Surgery work?

Step 1 — Movement-Disorder Evaluation

A neurologist reviews the diagnosis, symptoms, medication response and disease progression.

Step 2 — DBS Suitability Assessment

The team determines whether the patient's symptoms are likely to respond to DBS and whether surgery is appropriate.

Step 3 — Imaging and Surgical Planning

MRI and/or CT imaging is used to plan the electrode trajectory and identify the intended brain target.

Step 4 — Multidisciplinary Assessment

The evaluation may involve:

• Movement-disorder neurologist
• Functional neurosurgeon
• Neuropsychologist
• Psychiatrist where appropriate
• Anaesthetist
• Rehabilitation specialists
• DBS programming team

NIMHANS specifically describes multidisciplinary DBS assessment involving neurology, neurosurgery, psychiatry, neuropsychology and speech pathology.

Step 5 — DBS Surgery

Electrodes are implanted into selected brain targets.

For Parkinson's disease, common targets include:

• Subthalamic nucleus — STN
• Globus pallidus internus — GPi

The electrodes are connected to an implanted pulse generator.

Step 6 — Programming

After surgery, the stimulation settings are adjusted according to the patient's symptoms and response.

Step 7 — Medication Adjustment

The neurologist may adjust Parkinson's medication according to the response to stimulation.

Step 8 — Long-Term Follow-up

DBS requires continuing programming and neurological follow-up.

SCTIMST describes image-guided and microelectrode-recording-assisted DBS implantation and emphasises the need for continuing specialised care after surgery.

Q10 · What are the alternatives to DBS Surgery?

DBS is only one part of Parkinson's treatment.

Depending on the patient's condition, alternatives or complementary treatments may include:

• Optimisation of Parkinson's medicines
• Levodopa-based treatment
• Dopamine agonists
• MAO-B inhibitors
• Physiotherapy
• Occupational therapy
• Speech therapy
• Exercise programmes
• Gait and balance rehabilitation
• Fall-prevention programmes
• Management of sleep problems
• Management of swallowing difficulties
• Other advanced medication-based treatments

Some patients may benefit from continued medical treatment rather than surgery.

DBS should therefore be considered after a specialist evaluates the diagnosis, medication response, symptom profile and overall surgical suitability.

Q11 · What should Zambian patients ask before accepting a DBS quotation?

Before travelling to India, patients should ask:

1. Is my diagnosis definitely Parkinson's disease?
2. Am I a suitable DBS candidate?
3. Which DBS target is recommended?
4. Why is STN or GPi being recommended?
5. Which DBS device will be implanted?
6. Is the system rechargeable or non-rechargeable?
7. Is the device cost included?
8. Are electrodes and extension leads included?
9. Are surgery and hospitalisation included?
10. Is initial programming included?
11. How many programming sessions are included?
12. What happens if programming is needed after returning to Zambia?
13. What are the possible surgical complications?
14. What costs are excluded?
15. How long should I remain in India?

Patients should request an itemised written quotation before confirming travel.

Q12 · How long should Zambian patients stay in India?

The duration depends on whether the patient is travelling for evaluation, DBS surgery or postoperative programming.

These are planning estimates only.

Additional time may be required for imaging, neurological testing, neuropsychological assessment, surgery, initial programming and medication adjustment.

Q13 · What is recovery like after DBS Surgery?

Recovery varies according to the patient's general health, Parkinson's symptoms and type of procedure.

After surgery, patients may require:

• Wound monitoring
• Pain management
• Neurological observation
• Medication adjustment
• DBS programming
• Physiotherapy
• Gait and balance assessment
• Speech assessment where required
• Rehabilitation

DBS programming is an important part of treatment because stimulation parameters are adjusted according to the patient's response.

Possible surgical or treatment-related complications can include infection, bleeding, seizures, hardware problems, speech or balance difficulties and stimulation-related side effects.

The treating team should explain the patient's individual risks before surgery.

Q14 · How can Zambian patients manage DBS follow-up after returning home?

Before returning to Zambia, patients should obtain:

• Final diagnosis
• DBS operation report
• Device manufacturer
• Device model
• Device serial/reference information
• Electrode information
• Initial programming settings
• Updated medication list
• Programming schedule
• Follow-up recommendations
• MRI/device safety information
• Emergency instructions
• Contact information for the treating team where appropriate

Patients should ideally arrange follow-up with a neurologist or movement-disorder specialist in Zambia.

Because DBS settings can require adjustment over time, the patient should understand how future programming will be managed after returning home.

For rechargeable systems, the patient should also receive instructions regarding charging and device maintenance.

Long-term specialist follow-up is important after DBS; SCTIMST specifically notes that DBS patients require continuing access to specialised care.

Q15 · Should a Zambian patient travel to India for Parkinson's Treatment and DBS Surgery?

India can be considered by Zambian patients seeking specialist Parkinson's evaluation, advanced movement-disorder management and DBS assessment.

DBS may be relevant for selected patients whose motor symptoms, fluctuations, dyskinesias or medication-resistant tremor remain inadequately controlled despite appropriate medical treatment.

However, DBS is not suitable for every patient and is not a cure for Parkinson's disease.

Before travelling, patients should compare:

• Confirmed diagnosis
• Current symptoms
• Response to medication
• Motor fluctuations
• Dyskinesias
• Cognitive status
• Psychiatric status
• Recommended DBS target
• Device type
• Surgical risks
• Expected treatment benefits
• Total treatment cost
• Programming requirements
• Long-term follow-up arrangements

For an international patient, obtaining a movement-disorder specialist opinion based on complete medical records, medication history and brain imaging before travelling can help establish whether DBS is appropriate.
