Deep Brain Stimulation (DBS)

Deep brain stimulation (DBS) is a treatment that uses a small implanted device to send controlled electrical signals to specific areas of the brain. It may help reduce certain movement symptoms when medicines are no longer enough.

  • Tremors & Movement Disorders

    We have decades of experience caring for patients with tremors & movement disorders, pioneering minimally invasive treatments and leading research for new treatments to improve patient outcomes.

What Is Deep Brain Stimulation (DBS)?

Deep brain stimulation (DBS) is a treatment that places thin wires, called leads, into targeted areas of the brain and connects them to a small device implanted under the skin, usually near the chest. The device delivers electrical signals that help adjust abnormal brain activity linked to certain movement disorders.

DBS does not cure the underlying condition, but it may help reduce symptoms such as tremor, stiffness, slowed movement or involuntary movements in carefully selected patients. It is most often considered when symptoms continue to affect daily life despite medication or when medicines cause side effects that are hard to manage.

Why Choose Baptist Health?

Baptist Health Brain & Spine Care provides coordinated evaluation and treatment for people with complex neurological conditions. For patients considering DBS, care often involves close collaboration among physicians in movement disorders neurology, neurosurgery, imaging and rehabilitation.

Because DBS requires careful planning and long-term device management, patients benefit from a team approach that looks at symptoms, goals, overall health and response to previous treatment. This helps support treatment decisions that are tailored to each person rather than using a one-size-fits-all plan.

Why Choose Baptist Health?

How It Works

DBS uses a system with three main parts: leads placed in the brain, an extension wire under the skin and a pulse generator, which is the small battery-powered device that creates the electrical signals. Those signals do not destroy brain tissue. Instead, they help regulate the brain circuits involved in movement.

The device settings can often be adjusted over time during follow-up visits. This allows the care team to fine-tune treatment based on symptom control and side effects.

Who May Benefit

DBS may be considered for some people with conditions such as Parkinson’s disease, essential tremor, or dystonia. In general, it may be an option when symptoms are not well controlled with medicine alone, when symptom fluctuations interfere with daily life or when medication side effects become difficult to tolerate.

Not everyone with these conditions is a candidate for DBS. A full evaluation is needed to determine whether the treatment is appropriate, safe and likely to help.

Benefits and Risks

Potential benefits and risks can vary based on the condition being treated and the individual patient.

Potential Benefits

Potential benefits may include:

  • Less tremor or fewer other movement symptoms
  • Better day-to-day function
  • Fewer medication-related complications in select patients
  • Treatment that can be adjusted over time after implantation
Potential Risks

Potential risks may include:

  • Infection
  • Bleeding
  • Device problems
  • Pain at the implant site
  • Side effects related to stimulation
  • Future visits for programming, battery checks or hardware replacement

What to Expect

  • Before DBS, patients usually have a detailed evaluation that may include a neurological exam, imaging, medication review and discussions about goals of care. Some people may also need additional testing to help determine whether DBS is a good fit.

  • DBS is typically performed in stages, though the exact approach can vary. Some patients are awake for part of the procedure, especially when the surgical team wants real-time feedback during lead placement. Others may have surgery under general anesthesia, sometimes called asleep DBS. The care team decides on the safest and most appropriate approach based on the treatment plan and the patient’s needs.

    During surgery, the team uses detailed imaging and precise guidance to place the leads in the planned brain target. In some cases, the patient may be asked to respond to simple questions or move a body part so the team can confirm the lead position and watch for side effects. The pulse generator is then implanted under the skin, usually near the chest, either during the same operation or in a separate stage. The exact surgical plan, anesthesia approach and timing depend on the patient and the care team’s recommendations.

  • After the procedure, patients usually return for follow-up visits so the device can be programmed and adjusted. Improvements may not happen all at once. Fine-tuning settings can take time, and ongoing care is an important part of treatment.

Recovery

Recovery varies based on the surgical plan, overall health, and the condition being treated. Many patients need time for incision healing, follow-up appointments and device programming after surgery. The care team will provide instructions about activity, wound care, and when to call with concerns. Specific recovery timelines should be confirmed with the treating physician.

Frequently Asked Questions

  • DBS is used for certain neurological conditions that affect movement. It is most often associated with Parkinson’s disease, essential tremor and dystonia, but candidacy depends on the exact diagnosis, symptoms and response to other treatment.

  • Yes. DBS involves placing leads in specific areas of the brain and implanting a small device under the skin. Even so, it is different from procedures that remove tissue because DBS works by sending adjustable electrical signals.

  • No. DBS does not cure the underlying condition. It may help manage some symptoms and improve day-to-day function in selected patients, but most people still need ongoing neurological care after treatment.

  • A physician may discuss DBS when symptoms are not well controlled with medicine, when medication effects wear off too quickly or when side effects from medicine affect quality of life. A full evaluation is needed before deciding whether DBS is appropriate.

  • Many patients still need medicine after DBS, although doses or schedules may change. The goal is not always to stop medication completely, but to improve symptom control in a safer and more manageable way.

  • Yes. One of the main features of DBS is that the stimulation settings can often be adjusted after implantation. This allows the care team to fine-tune treatment based on symptoms, goals and side effects.

  • Recovery is different for each patient. Healing from the procedure is only one part of the process. Many people also need follow-up visits for device programming, which can take time before the full benefit of treatment is clear.

  • Risks can include infection, bleeding, hardware problems, pain near the implant site and stimulation-related side effects. The exact risks vary from person to person, so patients should review their medical history and treatment goals with their physician.
