Deep Brain Stimulation

What this procedure is

Deep brain stimulation (DBS) is a medical treatment that uses mild electrical pulses to help the brain function more effectively. It is often called a "pacemaker for the brain." The procedure involves placing thin, flexible wires, known as electrodes, into specific parts of the brain that control movement or mood.

These wires are connected to a small, battery-powered device called a neurostimulator. This device is usually placed under the skin near the chest or collarbone. The neurostimulator sends regular electrical signals to the brain to help regulate or block the abnormal signals that cause physical symptoms.

What it treats or fixes

DBS is primarily used to manage symptoms of movement disorders, especially when medications are no longer providing enough relief or are causing difficult side effects. Your clinician may recommend this procedure for several conditions, including:

• Parkinson’s disease: It can help reduce tremors, muscle stiffness, and slowed movement.
• Essential tremor: It is used to help control rhythmic shaking, most often in the hands or arms.
• Dystonia: It can help reduce involuntary muscle contractions that cause twisting or repetitive movements.

DBS is also sometimes used to treat other conditions like epilepsy or obsessive-compulsive disorder (OCD). It is important to know that while DBS helps manage symptoms and can improve quality of life, it is not a cure for these conditions.

How common it is & where it's done

Deep brain stimulation is a well-established treatment that has been used for decades. Thousands of people around the world receive this treatment every year. It is considered a standard option for patients who meet specific health and safety criteria.

This procedure is performed at specialized hospitals and major medical centers. It involves a dedicated medical team, including a neurosurgeon (a doctor who operates on the brain) and a neurologist (a doctor who treats brain and nerve disorders). These experts work together to ensure the device is placed correctly and programmed to meet each person's specific needs.

Recovery: What to Expect

After the procedure, most people stay in the hospital for one or two nights so the medical team can monitor their progress. You will have small bandages on your head and chest where the leads (thin wires) and the neurostimulator (the battery-powered device) were placed. It is normal to feel some mild soreness or a headache for a few days as you heal.

Your clinician will usually wait two to four weeks before turning the device on. This waiting period allows any swelling in the brain to go down. Once the device is active, you will have follow-up appointments to program the settings to best manage your symptoms.

Risks & Possible Complications

While this procedure is common, it does carry some risks that your clinician will discuss with you. These can include minor bleeding in the brain, infection at the incision site, or temporary feelings of confusion. In some cases, the hardware—such as the wire or the battery pack—may need to be adjusted if it moves or stops working correctly.

You should reach out to your care team if you notice any of the following signs during your recovery:

• A fever or chills.
• Increased redness, swelling, or fluid leaking from your incisions.
• A sudden change in your vision or speech.
• A significant or unexpected change in your mood.

Outcomes & Long-Term Results

The main goal of deep brain stimulation is to help reduce symptoms like tremors (shaking), muscle stiffness, and slow movement. While it is not a cure, it can make daily tasks much easier. Many patients find they are able to reduce the amount of medication they take, which can also help lower the side effects of those drugs.

It is important to know that results are not always immediate. It may take several months of small adjustments to the device settings to find the right balance for you. The battery in the neurostimulator typically lasts between three and five years, though some newer models are rechargeable and can last much longer before needing a simple replacement procedure.

Emotional Support & Reassurance

It is very common to feel a mix of hope and nervousness when starting this journey. You are not alone in this process; a team of specialists, including neurologists and surgeons, will be there to guide you. They will work closely with you to ensure the device is helping you meet your personal goals for movement and comfort.

DBS is a tool designed to help you get back to the activities you enjoy. Your clinician may suggest talking with other patients who have had the procedure or meeting with a counselor to help you navigate the adjustment period. This support system is there to help you feel confident and informed every step of the way.

Why doctors recommend it

Deep brain stimulation (DBS) is often recommended for people with movement disorders when medications are no longer providing enough relief. Your clinician may suggest this treatment if you have conditions such as Parkinson’s disease, essential tremor, or dystonia (a condition that causes muscles to twist or cramp). It is also sometimes used to treat epilepsy or obsessive-compulsive disorder (OCD).

Doctors typically consider DBS when medications cause bothersome side effects or when symptoms like tremors and stiffness return before it is time for the next dose of medicine. It is a choice for patients whose symptoms are still responsive to medication but are becoming harder to manage through pills alone.

Urgent vs planned treatment

DBS is a planned procedure rather than an emergency surgery. Because it is a specialized treatment, your medical team will take time to ensure it is the right choice for you. This process is often called an "elective" surgery because you and your doctor choose the best time to perform it based on your health and symptom progression.

Before the procedure, your clinician may perform several tests over several weeks or months. These often include brain imaging, such as an MRI, and "on-off" testing to see how your body reacts to your current medications. This careful preparation helps the surgical team map the specific areas of the brain that need treatment and ensures you are a good candidate for the procedure.

Goals of treatment

The primary goal of DBS is to improve your quality of life by making symptoms more manageable. While it is not a cure for movement disorders, it can act like a "pacemaker for the brain" to help regulate abnormal electrical signals. Success is measured by how much better you can move and function in your daily life.

Common goals include:

• Reducing physical symptoms like shaking (tremors), muscle stiffness, and slowness.
• Helping medications work more consistently throughout the day without frequent "wearing off" periods.
• Allowing some patients to reduce the amount of medication they take, which may lower the risk of drug-related side effects like uncontrolled movements (dyskinesia).

Who may benefit

Deep brain stimulation (DBS) is often used for people with movement disorders when medications are no longer working as well as they used to. Your clinician may suggest this treatment if you have Parkinson’s disease, essential tremor, or dystonia (a condition that causes muscles to twist or cramp).

This procedure is generally for those who have seen a good response to medications in the past but now face "off" periods, where symptoms return before the next dose. It can also help if your medications cause side effects like dyskinesia, which are uncontrolled, jerky movements.

DBS may also be an option for people with other conditions, such as epilepsy or obsessive-compulsive disorder (OCD), when other treatments have not provided enough relief. The goal is to help manage symptoms and improve your daily quality of life.

When it may not be the right option

While DBS can be very helpful, it is not the right choice for everyone. Your care team will perform a detailed evaluation to see if you are a good candidate. For example, DBS is usually not recommended for people with severe memory or thinking problems, such as dementia, as the surgery could make these issues worse.

It may also not be the best option if your symptoms do not respond to standard medications at all. For instance, if Parkinson’s symptoms do not improve with levodopa, they are less likely to improve with DBS. Additionally, people with certain untreated mental health conditions, like severe depression, may need to address those concerns first.

It is important to remember that DBS is a treatment to manage symptoms, not a cure. It does not stop a condition from progressing over time, though it can make the symptoms much easier to live with for many years.

Questions to ask your care team

Deciding on DBS is a big step. You should feel comfortable asking your medical team any questions you have. Here are some smart questions to bring to your next appointment:

• How much improvement can I realistically expect for my specific symptoms?
• What are the most common risks or side effects for someone in my health situation?
• Will I still need to take my current medications after the procedure?
• How often will the device need to be checked or adjusted?
• What is the recovery process like, and how soon can I return to my normal activities?

In the procedure room

The procedure room is a highly specialized environment designed for safety and precision. You will be surrounded by a team of experts, including a neurosurgeon, specialized nurses, and often a neurologist. The room contains advanced imaging equipment and monitors that track your brain activity and vital signs throughout the process.

Depending on the method used, your head may be held in a special frame to keep it perfectly still, or the team may use a "frameless" system with small markers. This ensures the surgeon can reach the exact area of the brain with pinpoint accuracy to provide the best possible results.

High-level steps

The procedure is typically done in two main stages. In the first stage, the surgeon places thin, insulated wires called electrodes into specific parts of the brain. To reach these areas, a small opening about the size of a coin is made in the skull.

In the second stage, a small device called an internal pulse generator—which is similar to a heart pacemaker—is placed under the skin of the chest. Finally, thin extension wires are guided under the skin of the neck to connect the brain electrodes to the chest device. These two stages may happen on the same day or at different times.

Anesthesia and pain control

For the brain portion of the surgery, your clinician may use local anesthesia to numb your scalp. While you may feel some pressure or hear sounds from the equipment, the brain itself does not have pain receptors, so you will not feel the electrodes being placed. Some patients remain awake for part of this stage to help the team test the device.

For the second stage involving the chest device, general anesthesia is usually used. This means you will be in a deep sleep and will not feel anything during the process. Your care team will provide medication to manage any soreness or discomfort as the anesthesia wears off.

Monitoring and safety steps

Safety is a top priority during the procedure. The team uses "brain mapping" to confirm the electrodes are in the best possible spot. This may involve microelectrode recording, which listens to the activity of individual nerve cells to identify the correct location.

If you are awake during the mapping, the team may ask you to move your arms, legs, or speak. This allows them to see how the stimulation helps your symptoms and ensures there are no unwanted side effects. Your heart rate, blood pressure, and oxygen levels are monitored constantly by the anesthesia team to ensure you are comfortable.

Immediately after the procedure

After the surgery is finished, you will be moved to a recovery area where nurses will watch you closely. You will likely have bandages on your head and chest to keep the small incisions clean and protected while they begin to heal. These dressings help prevent infection and keep the area stable.

It is common to feel some tiredness or a mild headache. Your clinician may use imaging, such as a CT scan or MRI, shortly after the procedure to double-check the placement of the electrodes. Most patients stay in the hospital for a day or two for observation before going home to rest.

Typical procedure length

The time required can vary depending on whether one or both sides of the brain are being treated. The brain electrode placement is the most detailed part and often takes several hours because of the careful mapping required to find the exact target.

The second part, placing the chest generator, is usually much faster and may take about an hour. Your surgical team will give you a more specific estimate based on your individual treatment plan and whether the stages are performed together or separately.

Common approaches (open vs minimally invasive)

Deep Brain Stimulation (DBS) is generally considered a minimally invasive surgery because it does not require a large opening in the skull. Instead, the surgeon creates a small hole, called a burr hole, to safely guide the thin wires (leads) to the exact spot in the brain. This approach helps protect healthy brain tissue.

Your care team may choose between two main ways to perform the procedure:

• Awake surgery: You are awake but relaxed with medication. This allows the care team to test the stimulation and ask you questions to ensure the leads are in the best possible location.
• Asleep surgery: You are under general anesthesia (fully asleep). The surgeon uses advanced imaging, such as MRI or CT scans, to guide the leads without needing you to respond.

Not every hospital offers the asleep option, and it may not be right for every patient. Your doctor will recommend the approach that is safest for your specific condition.

Partial vs total

DBS surgery involves placing two main parts: the leads in the brain and the neurostimulator (battery) in the chest. While it is possible to implant the entire system in one day, it is very common to split the process into two separate stages.

• Staged procedure: The surgeon implants the leads in the brain first. You then go home to heal for a few weeks. In a second, shorter surgery, the doctor places the battery under the skin near your collarbone and connects it to the leads.
• Simultaneous procedure: Both the brain leads and the chest battery are placed during the same operation.

Splitting the surgery is often chosen to reduce fatigue and allow the brain to recover from the first step before the system is turned on.

Revision or repeat procedures

Once the DBS system is in place, the leads in the brain typically remain there permanently. However, the device in your chest contains a battery that will eventually run out. Replacing the generator is a common, minor procedure performed as an outpatient service. It usually does not require returning to brain surgery.

There are two main types of batteries your clinician may discuss with you:

• Non-rechargeable: These are standard batteries that typically last between 3 to 5 years before needing replacement.
• Rechargeable: These batteries can last much longer, often around 9 years or more, but they require you to charge the device regularly at home.

In rare cases, a revision surgery may be needed if a wire moves or breaks, but for most people, repeat procedures are limited to battery maintenance.

Tests and imaging that may be done

Before the procedure, your care team needs to make sure deep brain stimulation (DBS) is a safe option for you. They will perform several tests to check your overall health and plan the surgery.

• Brain imaging: You will likely have an MRI or CT scan. These create detailed pictures of your brain to help the surgeon decide exactly where to place the leads (wires).
• Blood tests: These check for issues like clotting problems or infection risks to ensure your body can handle the surgery.
• Thinking and memory tests: You may meet with a specialist for neuropsychological testing. This checks your memory, mood, and thinking ability to ensure you are a good candidate for the procedure.

Medication adjustments

Your doctor will review all the medicines and supplements you currently take. It is important to follow their instructions exactly regarding what to take and what to stop.

• Blood thinners: To reduce the risk of bleeding, you may be asked to stop taking aspirin or other blood-thinning medications for a specific time before surgery.
• Symptom medications: If you are being treated for a movement disorder, your doctor might ask you to stop taking your regular medication for a short time before the procedure. This helps the surgical team see your symptoms clearly during the operation.

Note: Do not stop taking any medication unless your clinician specifically instructs you to do so.

Day-before and day-of instructions

As your surgery date approaches, your care team will give you a list of steps to follow at home. These steps help prevent infection and keep you safe during anesthesia.

• Fasting: You will usually be told not to eat or drink anything (including water) after midnight the night before surgery.
• Hygiene: You may need to shower and wash your hair with a special soap or shampoo to kill germs on your skin.
• Clothing: Wear loose, comfortable clothing to the hospital. Avoid wearing makeup, jewelry, or hairpins.
• Items to bring: Bring your ID, insurance card, and a list of your medications. Leave valuables at home.

General surgical risks

Deep brain stimulation is a common procedure, but like any surgery, it carries some risks. Because the surgery involves placing electrodes in the brain, there is a small risk of bleeding or stroke. Infection can also occur at the incision sites on the head or chest.

Other general risks associated with undergoing surgery and anesthesia include:

• Breathing problems
• Nausea
• Heart problems
• Allergic reactions to anesthesia

Your surgical team will monitor your vital signs closely throughout the procedure to manage these risks and keep you safe.

Procedure-specific complications

Some complications are specific to the device itself or the stimulation it provides. After the surgery, you may have temporary pain or swelling where the device was implanted. In some cases, the lead wire may move, erode through the skin, or the device may stop working correctly.

Once the device is turned on, the electrical pulses can sometimes cause side effects. These are often related to the stimulation settings and may include:

• Numbness, tingling, or jolting sensations
• Muscle tightness usually in the face or arm
• Speech or balance problems
• Vision changes, such as double vision
• Mood changes, confusion, or difficulty concentrating

How complications are treated

Many side effects caused by the stimulation are reversible. Because the device is programmable, your clinician can often stop these side effects by adjusting the settings wirelessly during an office visit. It may take several follow-up appointments to find the settings that work best for you without causing discomfort.

If an infection occurs, your doctor may prescribe antibiotics. In some situations, the system may need to be removed temporarily to treat the infection. If there is a mechanical problem with the hardware, such as a broken wire or a moved lead, additional surgery may be required to replace or reposition the device.

Pain control medicines

After the procedure, it is common to feel some mild discomfort or soreness at the sites where the surgery took place. Your clinician may suggest using over-the-counter pain relievers, such as acetaminophen, to help you stay comfortable during your recovery. These medicines are often enough to manage the dull ache that can occur as the incisions heal.

If you have more significant discomfort, your care team might provide a stronger prescription medication for a short period. It is important to tell your clinician about any allergies you have to pain medicines before the surgery begins. They will tailor your pain management plan to your specific needs and health history.

Antibiotics

Because Deep Brain Stimulation involves placing small devices inside the body, preventing infection is a top priority. Your clinician will likely give you antibiotics, which are medicines used to kill or stop the growth of germs. This helps ensure the area around the new hardware stays healthy.

These medicines are often given through an IV (a thin tube in your arm) just before the surgery starts. You may also be asked to take antibiotic pills for a few days after you go home. Your team will check for any history of drug allergies to make sure the antibiotic chosen is safe for you.

Blood thinners and clot prevention

Blood thinners are medicines that help prevent blood clots, but they can also increase the risk of bleeding during surgery. Your clinician will review all your current medications, including aspirin and other "antiplatelet" drugs, well before your procedure date. This is a standard safety step to reduce the chance of bleeding in the brain.

You will likely be asked to stop taking these medicines for several days or even a week before the surgery. Your care team will provide a specific schedule for when to stop them and when it is safe to start taking them again afterward. They may also suggest the following to keep your blood moving safely while you recover:

• Supplements: You may be asked to stop certain herbal remedies or vitamins that can thin the blood.
• Movement: Your team might encourage you to walk or move your legs shortly after surgery to prevent clots from forming in the legs.
• Compression: In some cases, you may wear special stockings that gently squeeze the legs to help with blood flow.

Emergency warning signs

Although serious complications are rare, it is important to act quickly if you notice signs of a medical emergency. You or a family member should call 911 or go to the nearest emergency room if you experience:

• A seizure or convulsion
• Sudden weakness, numbness, or paralysis on one side of the body
• Sudden trouble speaking or understanding what others are saying
• A severe headache that feels very different from normal surgical pain
• Sudden loss of vision or major vision changes

Call your surgeon or clinic if…

Contact your healthcare team if you notice signs that your body is not healing as expected. Your clinician will want to know if you develop:

• A fever (often defined as over 101°F or 38.3°C) or chills
• Redness, swelling, or fluid leaking from the incision sites on your head or chest
• Nausea or vomiting that stops you from keeping fluids down
• Pain that does not get better with your prescribed medicine

Expected vs concerning symptoms

It is common to feel drowsy or tired for a few days after the procedure. Most people also have some soreness or a mild headache around the area where the device was placed. These symptoms usually improve with rest and time.

However, you should watch for symptoms that get worse instead of better. While some temporary confusion can happen right after surgery, let your doctor know if confusion increases or does not go away. You should also report a stiff neck, double vision, or any new mood changes that concern you.

Non-surgical treatments

Before considering surgery, your clinician will usually recommend non-surgical ways to manage your symptoms. The most common approach is using medications. For conditions like Parkinson’s disease, medications help replace or mimic chemicals in the brain that control movement. These treatments can often manage tremors, stiffness, and slow movement for many years.

Other non-surgical options include:

• Physical therapy: Exercises to help improve balance, strength, and how you walk.
• Occupational therapy: Learning new ways to handle daily tasks, like eating or getting dressed.
• Speech therapy: Helping with voice volume or swallowing issues that sometimes come with movement disorders.

Watchful waiting

Watchful waiting means your medical team monitors your symptoms closely over time without starting a new procedure. This is common when your current medications are still working well. Since every person’s condition progresses at a different speed, your doctor may want to see how your symptoms change before making a big decision.

During this time, you might have regular check-ups to test your movement and coordination. If your symptoms are stable and you can still perform your daily activities, your clinician may decide that continuing with your current plan is the safest and most effective path for now.

When surgery becomes the best option

Surgery is generally considered when medications no longer provide enough relief. Over time, some people find that their medicine "wears off" more quickly between doses. Others may develop dyskinesia, which are involuntary, jerky movements caused by long-term use of certain medications.

Your clinician may suggest deep brain stimulation (DBS) if:

• Your symptoms significantly interfere with your quality of life.
• You have "on-off" periods, where your medication suddenly stops working.
• The side effects of your medications have become difficult to manage.
• Your symptoms still respond to some degree to medication, which often suggests DBS will be successful.

The goal of moving to surgery is to help stabilize your symptoms and potentially reduce the amount of medication you need to take each day.

Hospital services that commonly perform this surgery

Deep brain stimulation (DBS) is typically offered at large medical centers and university hospitals that specialize in brain health. Because this procedure requires high-tech equipment and a specialized team, it is usually found in departments focused on neurology (the study of the nervous system) and neurosurgery (surgery on the brain or spine).

At these centers, you will often work with a multidisciplinary team. This group may include neurologists who specialize in movement disorders, neurosurgeons, and neuropsychologists, who are experts in how brain health affects behavior and thinking. These teams work together to decide if the surgery is the right choice for your specific needs.

Patient resources and support services

Many hospitals provide educational resources to help you and your family prepare for the procedure. This may include printed guides, videos, or classes that explain how the device works and what to expect during recovery. Some centers also offer support groups where you can connect with other people who have had DBS.

Support services also include long-term care after the surgery is finished. Your clinician may provide programming services, which involve using a wireless device to adjust the electrical settings of your brain lead to get the best results. You may also have access to physical or occupational therapy to help you regain strength and improve your movement after the procedure.

Questions for choosing where to have surgery

Choosing where to have your surgery is an important decision. Your clinician may recommend a specific hospital, but you can also look for centers that have a lot of experience with your particular condition. It is often helpful to choose a facility that uses a team-based approach to care.

You may want to use this checklist when talking to a surgical team:

• How many DBS procedures does this hospital perform every year?
• Which specialists will be involved in my surgery and my follow-up care?
• What is the team's experience in treating my specific condition, such as Parkinson's disease or essential tremor?
• How often will I need to come back to the hospital for device adjustments?
• Who should I contact if I have questions or concerns once I am recovering at home?

Conditions commonly treated by this procedure

Deep brain stimulation (DBS) is a treatment that uses electrical signals to help parts of the brain work more effectively. Clinicians often suggest this procedure for people with movement disorders when medications are no longer providing enough relief or are causing difficult side effects.

Common conditions that may be treated with DBS include:

• Parkinson’s disease: A condition that affects movement and can cause shaking, stiffness, and slowed motion.
• Essential tremor: A nervous system disorder that causes rhythmic shaking, most often in the hands.
• Dystonia: A condition where muscles contract involuntarily, causing repetitive or twisting movements.
• Epilepsy: DBS may be used to help reduce the frequency of seizures in certain patients.
• Obsessive-compulsive disorder (OCD): In some cases, clinicians use DBS to help manage severe symptoms of OCD when other treatments have not worked.

Related symptoms people search for

People who are considering DBS often experience symptoms that make daily tasks, like eating or walking, more difficult. These symptoms can vary depending on the underlying condition, and your clinician can help determine if DBS is a suitable option for your specific needs.

Common symptoms associated with these conditions may include:

• Tremors: Uncontrolled shaking that can happen in the hands, arms, legs, or head.
• Rigidity: A feeling of stiffness in the muscles that makes it hard to move the arms, legs, or body freely.
• Bradykinesia: This is the medical term for slowness of movement, which can make simple tasks take much longer than usual.
• Dyskinesia: These are involuntary, jerky, or swaying movements that can sometimes be a side effect of long-term medication use.
• Balance and walking issues: This may include feeling unsteady or experiencing a "freezing" sensation where it feels difficult to take a step.

Evidence overview

Deep Brain Stimulation (DBS) is a well-established treatment used to help manage symptoms of certain neurological conditions. It is approved by the Food and Drug Administration (FDA) for specific movement disorders, including Parkinson’s disease, essential tremor, and dystonia. It is also approved for use in epilepsy and certain cases of obsessive-compulsive disorder (OCD).

Medical evidence shows that while DBS is not a cure, it can significantly improve quality of life for many patients. The goal is often to reduce symptoms like shaking, stiffness, and slow movement. For some people, successful DBS therapy may allow them to lower their medication doses, which can help reduce medication-related side effects.

Safety notes and individualized care

Because DBS involves brain surgery, it carries certain risks. Your surgical team will take many precautions to keep you safe, but possible complications can include infection, bleeding, or reactions to anesthesia. Although rare, serious issues such as stroke or seizures can occur during or after the procedure.

Once the device is implanted and turned on, the electrical stimulation can sometimes cause side effects. These may include:

• Numbness or tingling sensations
• Muscle tightness in the face or arm
• Speech or balance problems
• Mood changes

Fortunately, these stimulation side effects are often reversible. Your clinician can usually stop or reduce them by adjusting the settings on your device wirelessly. There is also a small risk of hardware issues, such as a wire moving or breaking, or the battery needing replacement over time.

DBS is not the right choice for everyone. Your healthcare team will perform detailed tests to ensure you are a good candidate. They will consider your overall health, your specific symptoms, and how well you respond to current medications before recommending surgery.
