Deep Brain Stimulation (DBS) Surgery, Procedure and Cost

Why Choose PACE Hospitals for Deep Brain Stimulation Surgery?

Types of Deep Brain Stimulation 

Deep Brain Stimulation (DBS) can be classified based on anatomical target, surgical types, lead type and stimulation methods. These classifications guide treatment decisions based on the patient’s condition and response to therapy.

By Anatomical Target (common targets)

Each type of DBS targets a different part of the brain involved in controlling abnormal movement, providing personalised and effective symptom relief. Based on the target site, DBS are classified into the following types:

• Globus pallidus internus
• Subthalamic nucleus
• Thalamus

• Globus pallidus internus" Globus Pallidus Internus DBS is used for dystonia (a neurological movement disorder) and advanced Parkinson's disease, particularly for reducing stiffness, muscle spasms, and involuntary movements. It is usually selected for patients who have severe movement alterations or side effects of dystonia with medications.
• Subthalamic nucleus: Subthalamic nucleus DBS is frequently used to treat Parkinson's disease tremors, rigidity, and slowed movements by controlling abnormal brain signals. It enhances general motor control and often reduces the need for high doses of Parkinson's drugs.
• Thalamus: Thalamic DBS targets specific thalamic nuclei to control severe tremors that don't respond to drugs. It is especially helpful for people whose main problem is tremor that makes it hard for them to move around, without causing much stiffness or slowness.

By surgical procedure / guidance

Surgical Procedure Types in DBS refer to the methods used for precise lead placement during the surgery. It has two types:

• Frame-Based Stereotactic
• Interventional MRI/CT-Guided ("Asleep")

• Frame-Based Stereotactic: This technique involves fixing the patient's head in a rigid frame, using preoperative MRI to calculate target coordinates, and intraoperative microelectrode recording (MER) for physiological confirmation. The patient is usually awake during the procedure for real-time feedback.
  
• Interventional MRI/CT-Guided ("Asleep"): This technique uses real-time MRI or CT scans to guide lead placement while the patient is under general anesthesia, allowing direct anatomical targeting without the need for MER, offering a less invasive and more streamlined process.

By lead type and stimulation methods

By Lead Type and stimulation methods refers to the different electrode designs and methods of stimulation used in DBS to achieve optimal therapeutic effects. It includes:

• Conventional (cylindrical contact) DBS
• Directional (segmented contact) DBS
• Monopolar vs. Bipolar DBS

• Conventional (cylindrical contact) DBS: This uses electrodes with four cylindrical contacts, delivering monopolar stimulation. It is the standard configuration for treating Parkinson's disease, tremors, and dystonia.
• Directional (segmented contact) DBS: Uses segmented electrodes to control a current in certain directions, which improves position selectivity and reduces side effects. This process is becoming more and more common for Parkinson's disease and essential tremor.
• Monopolar vs. Bipolar DBS: Monopolar has one active contact with the implanted pulse generator that acts as the return, which makes the electric field larger. Bipolar uses two active contacts to make the electric field more focused, which is helpful for stimulating thalamic tremor.
  

Deep Brain Stimulation Indications

When the symptoms of some neurological disorders start to impair everyday functioning and quality of life seriously and are not sufficiently managed with medication, deep-brain stimulation is advised. It is usually recommended for patients who initially respond to medications but subsequently experience fluctuations, paralysing symptoms, or adverse drug reactions. DBS is not a cure, but it does help control abnormal brain signals and enhance motor function. Deep brain stimulation is frequently indicated for the following reasons:

• Parkinson’s Disease
• Dystonia
• Essential tremor
• Epilepsy
• Obsessive-compulsive disorder (OCD)

Parkinson’s Disease

DBS is advised in parkinson’s disease that targets the precise brain regions which regulate abnormal movement control. Medication alone may become less effective as the illness worsens or result in serious side effects like involuntary movements and motor fluctuations. Although drugs may still be useful in some conditions, DBS is frequently advised because it provides more dependable, long-term symptom control. By changing abnormal brain signals, DBS can significantly reduce tremor, stiffness, and poor movement quality, enhancing daily functioning and quality of life.

Dystonia

Dystonia is characterised by uncontrolled, painful muscle movements. Deep brain stimulation (DBS), especially globus pallidus internus DBS, provides significant relief from the main symptoms of dystonia by disrupting abnormal activity within the brain's motor control circuits. Advances in neuroimaging and DBS technology are helpful in target selection, stimulation flexibility, and long-term outcomes.

Essential tremor

DBS is advised for essential tremors when drugs are insufficient to treat symptoms, and the tremor substantially interferes with daily activities. This effective and successful treatment reduces tremor by adjusting abnormal brain activities. DBS provides long-term tremor control and improves the patient's quality of life with medically refractory essential tremor; it does not cure the underlying illness.

Epilepsy

When conventional treatments are insufficient to control drug-resistant seizures in epilepsy patients, DBS is utilised. DBS may enhance cognitive abilities such as memory, attention, and executive control, in addition to reducing seizure frequency. DBS modulates abnormal brain activity by stimulating particular brain regions. DBS is an effective treatment option for epilepsy patients with related cognitive impairment due to its demonstrated safety and new cognitive advantages.

Obsessive-compulsive disorder (OCD)

Patients with severe, treatment-resistant obsessive-compulsive disorder (OCD) who do not improve with the best medication and cognitive behavioural therapy may benefit from deep-brain stimulation (DBS). Research demonstrates that DBS can significantly reduce symptoms over the short and long terms. However, its use requires appropriate patient selection and management by skilled multidisciplinary teams that include behavioural therapists, psychiatrists, and neurosurgeons.

Deep Brain Stimulation Contraindications

Deep brain stimulation is unsuitable for some individuals, even though it is effective. Appropriate patient selection is important to ensure safety and substantial clinical benefit. Certain medical, neurological, and psychiatric conditions may reduce the DBS effect or increase the risk of complications. When assessing a patient for DBS therapy, the following conditions can be considered as important contraindications or limiting factors. These include:

• Untreated psychiatric disorders
• Clinically defined dementia or severe cognitive impairment
• Advanced axial motor impairment (inability to stand or walk in the best-treated state)
• Advanced stage of neurodegenerative disease
• Significant medical comorbidities increase surgical risk
• Structural brain changes or marked brain atrophy

Untreated psychiatric disorders

DBS is not recommended for patients with uncontrolled psychiatric disorders, including severe depression, psychosis, or active suicidal ideation. These conditions can get worse after surgery, which can make it difficult for postoperative adjustment and outcomes. Before considering DBS, the patient's psychological condition must be stable.

Clinically defined dementia or severe cognitive impairment

Patients suffering from dementia are not suitable for DBS due to their inability to respond to cognitive decline in advanced neurodegeneration to stimulation. DBS might impair cognition and daily life activities. Before surgery, a careful cognitive assessment is necessary.

Advanced axial motor impairment (inability to stand or walk in the best-treated state)

Even with the best medical care, DBS is unlikely to help a patient regain mobility if they are unable to stand or walk. Severe walking and balance issues frequently react poorly to stimulation. Consequently, DBS should be considered prior to the onset of advanced axial symptoms.

Advanced stage of neurodegenerative disease

The efficacy of DBS is limited in advanced stages of conditions like Parkinson's disease due to extensive brain degeneration. At this point, circuits that DBS can modulate are frequently no longer responsible for symptoms. Better results are achieved in early- to mid-stage illness.

Significant medical comorbidities increase surgical risk

Some of the conditions, like uncontrolled high blood pressure, bleeding disorders, or amyloid angiopathy, raise the risk of surgical problems, such as bleeding in the brain. Anaesthesia and recovery risks are also increased by poor general health.

Structural brain changes or marked brain atrophy

Accurate electrode placement may be challenging if there is significant brain atrophy or anatomical abnormalities. These modifications raise the possibility of intraoperative brain shift and targeting errors. DBS may therefore be unsafe or less successful in these patients.

Benefits of Deep Brain Stimulation

DBS has demonstrated a significant clinical benefit in several neuropsychiatric disorders and movement disorders. It is widely used because it is reversible, adjustable, and enables precise control of malfunctioning brain circuits. The following are the benefits:

• Effective symptom relief 
• Adjustable & reversible
• Target-Specific Action
• Reduced medication burden
• Enhanced quality of life and daily function

Effective symptom relief 

DBS effectively reduces motor symptoms such as tremor, rigidity, bradykinesia, and motor fluctuation and dyskinesias. It also helps control unusual behaviours and some psychological problems in conditions like Parkinson's disease, dystonia and essential tremors. This makes daily life easier and improves quality of life.

Adjustable & reversible

Deep brain stimulation causes slight changes to the brain and can be stopped by removing or turning off the battery if any side effects occur. The stimulation settings are easily adjustable without additional surgery, allowing treatment to be tailored as symptoms change. Patients can also control the device using a programmer, including turning it off or making minor adjustments when needed.

Target-Specific Action

Deep brain stimulation targets specific brain nuclei that cause abnormal symptoms. Only these specific regions receive electrical signals; the surrounding brain tissue is mainly unaffected. This targeted action reduces unwanted side effects while helping correct abnormal neural circuits.

Reduced medication burden

Many patients require a low dosage of medications to manage their symptoms after deep brain stimulation. This is because DBS directly modifies the abnormal brain circuits that cause the disease. Medication reduction improves overall quality of life by reducing side effects like nausea, sedation, and dyskinesia.

Enhanced quality of life and daily function 

Patients' physical and mental quality of life, as well as their motor symptoms, have been demonstrated to be considerably improved by deep brain stimulation (DBS). DBS offers significant improvements in general functioning and health-related quality of life in addition to decreasing dyskinesia, underscoring its wider therapeutic benefit.

Deep Brain Stimulation Procedure

The deep brain stimulation surgery procedure includes the following steps:

Before deep brain stimulation surgery

• Before the surgery, the neurologist and neurosurgical team perform a preoperative evaluation to make sure the patient is suitable for DBS. This includes a physical examination, a medical history, and imaging tests like CT or MRI scans to check the specific areas that are causing the symptoms. Additional assessments by specialists, such as a psychologist, are required to assess cognitive and emotional problems for surgery.
  
• Patients must inform the doctor about all allergies (medications, anaesthetics) and provide a complete list of medications, including prescribed drugs, over-the-counter medicines, vitamins, and herbal supplements. Certain medications, especially blood thinners and anti-inflammatory drugs, may need to be stopped before surgery as advised by the medical team.
  
• Before DBS surgery, lifestyle modifications such as quitting smoking, reducing alcohol intake, and maintaining good control of conditions such as diabetes or heart disease are advised, which can reduce surgical risks and promote better recovery.
  
• Women who are pregnant must inform the doctor, as this may affect surgical planning and imaging choices.
  
• Before the procedure, informed consent is obtained after the surgeon explains the benefits, risks, alternatives, and expected outcomes of DBS. Patients are instructed to fast before surgery, follow medication guidelines, arrive at the hospital on time, and arrange transportation and home support for the postoperative period.

During deep brain stimulation surgery

• Anaesthesia and Monitoring: DBS surgery is done with either local or general anaesthesia, depending on the stage of the procedure. Local anaesthesia is often used during electrode placement so the patient can remain awake for neurological testing, and their vital signs can be continuously monitored. During the implantation of a neurostimulator, general anaesthesia is used to keep the patient safe and comfortable.

• Surgical Technique: DBS is usually performed in one or two stages, depending on patient-specific considerations and surgical strategy. The procedure involves carefully targeting particular areas of the brain that produce the symptoms.

• Stage 1: Lead Placement: Before electrode implantation, the scalp may be numbed, some hair may be shaved, and the head may be held in a unique frame with tiny screws. After local anaesthesia, a small opening (burr hole) is drilled in the skull, and the lead is inserted into the targeted brain region on one or both sides as needed. To verify proper electrode placement and effective symptom control, electrical stimulation is tested, and the patient may be asked to respond to questions or move limbs.

• Stage 2: Neurostimulator Implantation: It is carried out under general anaesthesia to keep the patient asleep and pain- free. The neurostimulator is implanted beneath the skin after the surgeon makes a tiny incision, typically beneath the collarbone. An extension wire is tunnelled beneath the skin of the head, neck, and collar bone to connect the stimulator to the brain leads. The incision is then closed, leaving the device hidden under the skin. Electrical impulses travel from the neurostimulator to the brain once they are connected, helping block abnormal signals that cause symptoms.

After deep brain stimulation surgery

• After DBS surgery, the patient is usually monitored closely in the recovery room for vital signs and neurological status. This helps in detecting early complications such as infection, bleeding, or changes in neurological function.
• During recovery, the patient is advised to rest and slowly resume gentle activities as directed by the neurology team. Appropriate medications and antibiotics may be given to prevent pain and infection.
• After surgery, the neurostimulator is turned on and programmed, with adjusted stimulation settings based on symptom response.
• Before discharge, the patient is given instructions on wound care, activity restrictions, medication use, and follow-up appointments, and advised to report any concerning symptoms promptly.

Deep Brain Stimulation Complications

Like all invasive surgeries, deep brain stimulation has some risks. Complications result from the surgical procedure, stimulation effects on nearby brain tissue, or long-term device-related problems. Although many side effects are manageable, careful monitoring is necessary. The following are the complications:

• Surgical-related complications
• Device-related (hardware) complications
• Stimulation-related side effects
• Neuropsychiatric and cognitive effects
• General postoperative effects
  
  

Surgical-related complications

There are minimal surgical risks associated with DBS, which involves implanting electrodes deep within the brain. These include seizures, brain tissue edema, brain bleeding, and infections. Despite being rare, these complications can cause some neurological symptoms and require immediate medical attention. Sterile methods, skilled surgical teams, and careful imaging greatly lower these risks.

Device-related (hardware) complications

DBS systems consist of a pulse generator, extension wires, and implanted leads. complications like lead movement, damage to the wire, battery problems, or device malfunction may arise over time. These problems might require minor additional surgery or device reprogramming to control symptoms.

Stimulation-related side effects

Electrical stimulation can occasionally spread to nearby brain areas. Tingling sensations, stiff muscles, difficulties with balance, blurred vision, or trouble speaking may arise from this. Changing the stimulation settings can frequently improve or completely reverse these side effects, which are usually temporary.

Neuropsychiatric and cognitive effects

After DBS, some patients may experience mood or behavioural changes, including anxiety, depression, irritability or impulsivity. There may also be slight alterations in thinking, memory, or attention, particularly in susceptible people. Early detection and management of these effects are made possible by thorough pre-surgical evaluation and continuous monitoring.

General postoperative effects

After DBS surgery, headache, dizziness, pain at the incision sites, and mild discomfort surrounding the implanted device are common short-term side effects. With regular postoperative care and medication, these symptoms, which are a normal part of recovery, usually go away in a few days or weeks.

Deep Brain Stimulation Surgery Recovery

Recovery time for deep brain stimulation (DBS) is usually a few weeks to several months. Most patients stay in the hospital for one to three days after surgery. Healing the incision, controlling pain or swelling, and progressively resuming their regular activities are the main goals of their early recovery. Light movement is encouraged during this phase, but strenuous activity is not recommended.

After adequate healing, the DBS device is typically programmed and activated 2 to 6 weeks after surgery. Regular follow-up appointments help optimise symptom control and functional recovery over the following two to three months by adjusting stimulation. By three to six months, the majority of patients experience significant improvement, with continued monitoring and adjustments as necessary.

What questions can patients ask the healthcare team about deep brain stimulation surgery?

• When can I go home after deep brain stimulation surgery?
• When is my next follow-up visit, and what will happen during DBS programming?

Frequently Asked Questions (FAQs) on Deep Brain Stimulation (DBS) Surgery

What is deep brain stimulation?

How does deep brain stimulation work?

DBS works by delivering controlled electrical stimulation. DBS targets abnormal electrical signals in brain regions that regulate movement, which are the cause of movement symptoms in Parkinson's disease. A neurostimulator positioned beneath the collarbone is connected to electrodes implanted in specific brain areas. The device is programmed over a period of weeks to months to achieve maximum symptom control while minimising side effects.

How long does deep brain stimulation last?

Patients with Parkinson's disease, essential tremor, and dystonia can maintain significant long-term motor improvement for seven to ten years with deep brain stimulation. But over time, the amount of benefit might gradually decline. Battery life varies based on the condition treated and stimulation settings used, and worsening of symptoms when stimulation is turned off indicates continued disease progression.

Is deep-brain stimulation reversible?

Deep brain stimulation is regarded as reversible in a limited, complicated manner, as stimulation can be changed, stopped or terminated without causing damage to brain tissue. However, new evidence suggests that DBS may also have effects that don't depend on stimulation and could last for a long time. This means that it is not completely reversible in all ways and should be examined carefully.

Who are unsuitable for Deep Brain Stimulation (DBS) therapy?

Deep brain stimulation is not suitable for all patients, so careful selection is necessary to ensure safety and benefit. People with severe cognitive impairment, advanced neurodegenerative disease, significant surgical risk, untreated psychiatric illness, or significant brain structural abnormalities are generally not advised to use it.

Is deep brain stimulation a cure?

No. DBS is not a cure. Although it is an effective tool for managing and improving movement symptoms like involuntary movements and difficulty maintaining posture, it does not stop or slow the progression of neurodegeneration in movement disorders like Parkinson's disease.

How effective is deep brain stimulation for essential tremor?

Patients with essential tremor whose symptoms do not improve with medication may find deep brain stimulation to be a safe and effective treatment. Although more research is required to compare stimulation targets and evaluate long-term effects on quality of life and cognition, it may generally reduce the severity of tremors.

Is Deep Brain Stimulation (DBS) Surgery Covered by Insurance at PACE Hospitals?
