At a glance
Deep Brain Stimulation (DBS) is a neurosurgical procedure in which a small electrode is permanently implanted inside a specific region of the brain to deliver controlled electrical pulses that correct abnormal nerve signals.
Many movement and mood disorders are caused by misfiring circuits deep inside the brain. The implanted electrode connects by a thin wire under the skin to a small pulse generator, similar to a pacemaker, placed beneath the skin of the chest. That generator sends steady, precisely tuned electrical signals to the target brain region, interrupting the faulty signalling without destroying the tissue. The settings can be adjusted at any time after surgery, which means the therapy can be fine-tuned as the patient's condition changes over time.
Medical Condition
DBS is used when a neurological or psychiatric condition causes disabling symptoms that no longer respond well enough to medication alone.
- Parkinson's disease, especially when tremor (shaking), rigidity (muscle stiffness), or slow movement is severe and medications cause unpredictable on-off swings
- Essential tremor, a common condition where the hands shake uncontrollably during everyday tasks
- Dystonia, a disorder in which muscles contract involuntarily and hold the body in abnormal postures
- Obsessive-compulsive disorder (OCD), when severe symptoms have not improved after multiple courses of medication and therapy
- Epilepsy (recurrent seizures) that has not responded to two or more anti-seizure medications
DBS is not suitable for everyone, and a full neurological and psychological assessment is always carried out first. Surgeons typically avoid it in the following situations.
- Significant dementia (severe memory and thinking problems), because surgery may worsen cognitive function
- Active psychiatric illness that is not yet stabilised
- Severe cardiovascular disease or other conditions that make general anaesthesia too risky
- Brain tumour or structural brain abnormality in or near the target area
- Conditions requiring frequent MRI scans after surgery, since some DBS systems have MRI restrictions
Risks & Complications
DBS is a major brain operation and carries real risks; most are uncommon, but patients and families need to understand them before agreeing to proceed.
- Bleeding inside the skull (intracranial haemorrhage), which can cause stroke-like symptoms or, rarely, be life-threatening
- Infection at the wound site, along the wire, or around the pulse generator, sometimes requiring removal of the hardware
- Seizure (sudden uncontrolled electrical activity in the brain) in the period shortly after surgery
- Lead migration: the electrode shifting from its intended position, reducing effectiveness or causing new symptoms
- Hardware problems such as wire breakage, erosion of the device through the skin, or pulse generator failure
- Stimulation side effects including tingling, muscle twitching, speech or balance difficulties, mood changes, or double vision, most of which can be reduced by adjusting the device settings
- Cognitive changes such as mild memory difficulties, more commonly in older patients
- Anaesthesia-related risks including allergic reactions and, very rarely, serious cardiovascular events
- Worsening of depression or, in rare cases, new psychiatric symptoms
Preparation & Procedure
Preparation for DBS begins weeks before the operation. The team typically runs a series of tests to map the brain, assess general health, and establish a baseline record of the patient's movement or other symptoms.
Patients are usually asked to stop blood thinners and anti-inflammatory medicines several days before surgery, because these raise the risk of bleeding in the brain. The exact timing is decided by the surgical team. Smoking makes wound healing slower, and the team will usually discuss reducing or stopping it ahead of surgery. Alcohol should be avoided in the days leading up to the procedure.
Common tests run in the weeks before surgery include a high-resolution MRI or CT scan of the brain, neuropsychological testing (assessments of memory, thinking, and mood), an electroencephalogram (EEG, a recording of brain electrical activity) in some centres, and blood tests to check clotting and general organ function. For Parkinson's patients, a specific medication test is often done to measure how much the symptoms respond to the current drug regimen.
On the day of surgery, most patients stop eating and drinking several hours beforehand as directed by the anaesthesia team. Here is a general outline of how the procedure unfolds, though steps and their order can vary between hospitals and between patients.
- A lightweight metal frame or a frameless tracking system is fixed to the head to guide the surgeon to the exact millimetre target inside the brain
- Imaging such as CT or MRI is taken with the frame in place to calculate the precise coordinates of the target brain region
- The scalp is numbed with local anaesthetic. In many hospitals the patient remains awake during electrode placement so the team can ask questions and monitor responses in real time
- One or two small holes, called burr holes, are drilled through the skull
- The electrode is guided slowly through the brain to the target area, with continuous electrical recording to confirm the correct location
- Stimulation is briefly switched on and the patient is asked to move or speak so the team can verify benefit and check for side effects
- Once position is confirmed, the electrode is secured
- In a separate step, usually under general anaesthesia, the pulse generator is placed under the skin of the chest and connected to the electrode by a wire tunnelled under the skin of the neck and scalp
- Wounds are closed and the device is activated or left off until the first programming session, which usually happens a few weeks later
Aftercare
Recovery after DBS happens in stages. The first days are spent in hospital under close neurological monitoring, and most patients are discharged within a week, though this varies with the individual and the hospital.
- The scalp incision and the chest wound are checked regularly; patients are told what signs of infection to watch for, such as redness, swelling, warmth, or discharge
- Strenuous activity, heavy lifting, and contact sports are restricted for several weeks while the electrode settles in place
- Stretching or bending the neck sharply is usually avoided in the first weeks to protect the wire connecting the electrode to the generator
- The first programming session, where a specialist adjusts the stimulation settings for the first time, usually happens a few weeks after surgery once swelling in the brain has settled
- Multiple programming visits over the following months are normal; finding the optimal settings takes time and patience
- Some patients continue their existing medications, often at reduced doses, because the stimulation and medication work together
- For Parkinson's patients, physiotherapy and speech therapy may be recommended to make the most of the improvement in motor control
- Long-term follow-up is ongoing: the pulse generator battery needs monitoring and will eventually need replacing, usually after several years
- Patients are given a device identification card to carry at all times, because airport security scanners and some medical equipment can interact with the implant
- Certain medical procedures, particularly some MRI scans and diathermy (deep-heat physiotherapy), require special precautions or may be restricted depending on the specific DBS system used
Cost & What Determines It
DBS is one of the most complex and resource-intensive procedures in neurosurgery, and its cost varies widely depending on a combination of factors that are specific to each patient's situation and each hospital's setting.
- Complexity of the condition: whether one side of the brain or both sides need electrodes placed (bilateral DBS requires a longer, more technically demanding operation)
- Type and brand of the implanted system: rechargeable pulse generators cost more upfront but reduce battery-replacement surgery frequency; non-rechargeable units cost less initially but require more frequent replacements
- Hospital class and country: a major academic neurosurgery centre in a high-income country will price very differently from a private specialist hospital in a middle-income country
- Length of hospital stay and intensive monitoring in the days following surgery
- Number of specialist consultations before surgery, including neurologist, neuropsychologist, and anaesthesiologist
- Intraoperative neurophysiology: the use of microelectrode recording and specialised monitoring during placement adds cost
- Imaging: multiple high-resolution MRI and CT scans are needed at different stages
- Programming sessions after surgery: these are billed separately in many hospitals and several sessions are needed in the first year
- Future battery replacement surgeries, which are a predictable long-term cost
- Rehabilitation services such as physiotherapy and speech therapy if included in or after the package
Hospital packages for DBS typically cover the surgeon and anaesthesiologist fees, the operating room, the implant itself, and the initial hospital stay. What is often billed separately includes pre-operative specialist consultations, the neuropsychological evaluation, post-operative programming visits, rehabilitation sessions, and any complications requiring additional treatment.
BPJS Kesehatan and most Indonesian private insurance policies do not cover treatment received outside Indonesia, so patients who choose to have DBS abroad generally pay from personal funds or through an international private health insurance plan that explicitly covers overseas surgery. Before travelling, asking the hospital for a written, itemised cost estimate that covers both the procedure itself and the likely follow-up needs is the most reliable way to understand the true total expense and avoid unexpected bills.
Frequently Asked Questions
How many sessions does Deep Brain Stimulation take?
Deep Brain Stimulation is usually done in one surgical procedure, but the process happens in stages. First, a neurosurgeon places thin electrodes (fine wires) deep inside the brain, then a small pulse generator (the battery device that sends electrical signals) is implanted under the skin near the chest or collarbone, often in the same operation or a few days later. After surgery, your care team will schedule follow-up visits over several weeks to program and fine-tune the device to your needs.
How does Deep Brain Stimulation feel, and will it hurt?
During surgery, most patients are awake for part of the procedure so they can respond to the surgeon's questions, though medication is given to keep them calm and comfortable. You may feel pressure on the head from the frame that holds it still, but the brain itself does not feel pain. Once the device is active, most people do not feel the electrical pulses, though some notice a brief tingling or warmth when the settings are first adjusted.
How soon will I notice results after Deep Brain Stimulation?
Some improvement in symptoms, such as tremor (shaking) or stiffness, may be noticeable soon after the device is switched on, but the full benefit usually builds up over several months of programming. Your neurologist will adjust the stimulation settings at each follow-up visit to find the combination that works best for you. Living with a stimulation device also takes some time to get used to, so patience through the adjustment period is part of the process.
How much does Deep Brain Stimulation cost?
The cost varies quite a bit depending on several factors specific to this procedure. The biggest driver is the implanted pulse generator and electrodes, which are specialized medical devices with their own price range, and whether one or both sides of the brain are treated also affects the total. Hospital class, the length of your stay, and the neurosurgery team's fees all contribute as well. Requesting a written estimate from the hospital before you travel is the most reliable way to understand your actual costs.
