The procedure involves five main steps. The entire process takes 5 to 7 hours the surgery generally takes 3 to 4 hours.

Step 1. attach stereotactic frameThe procedure is performed stereotactically, which requires attaching a frame to your head. The pin sites are injected with local anesthesia to minimize discomfort. You will feel some pressure as the pins are tightened. A metal cage, which looks like a birdcage, is placed on the frame .

Step 2. MRI or CT scanYou will undergo an imaging scan using either computerized tomography or magnetic resonance imaging . The rods of the bird cage show up on the scan and help the surgeon create landmarks that will aid in the exact targeting of the desired brain structure. The cage is removed after the scan, but the frame remains in place to secure the head during surgery.

Step 3. perform a craniotomyNext, you will be taken to the operating room . You will be positioned on an OR table, and the stereotactic frame will be secured to the table. This prevents any small movements during this very precise procedure. You will remain awake throughout the procedure, and no sedatives will be given as they can mask the Parkinsons symptoms, whose source the surgeon is trying to find within the brain. Next, a local anesthetic is injected in a site at the top of your head. A small skin incision is made and a hole, about the size of a quarter, is drilled into the skull.

Will I Be Asleep During The Entire Procedure

You will be sedated or receive local anesthesia for part of the procedure, may or may not be awake for lead and electrode placement, and will be asleep when the impulse generator is implanted. To provide more details:

  • A local anesthetic is applied to areas of the head where pins or screws are used to secure the head frame and sedation is given.
  • You will be sedated during the beginning of the procedure, while the surgical team is opening the skin and drilling the opening in the skull for placement of the lead.
  • Most patients will be awake for lead and electrode placement. This part of the procedure is not painful, as the brain does not feel pain. Being awake allows the surgical team to interact with you when testing the effects of the stimulation. However, some patients who cannot tolerate the procedure while awake can have the electrode and lead placed under general anesthesia. The lead placement is guided in real time by magnetic resonance imaging. The procedure is performed in a special MR-equipped operation room.
  • Implantation of the pulse generator in the chest and connection of the leads from the device to the lead in the brain is usually done under general anesthesia.

How Should I Care For The Surgical Area Once I Am Home

  • Your stitches or staples will be removed 10 to 14 days after surgery.
  • Each of the four pin sites should be kept covered with band aids until they are dry. You will be able to wash your head with a damp cloth, avoiding the surgical area.
  • You may only shampoo your hair the day after your stitches or staples are removed, but only very gently.
  • You should not scratch or irritate the wound areas.

Deep Brain Stimulation: A Paradigm Shifting Approach To Treat Parkinson’s Disease

  • Department of Neurology, Duke University Medical Center, Durham, NC, USA

Parkinson disease is a chronic and progressive movement disorder classically characterized by slowed voluntary movements, resting tremor, muscle rigidity, and impaired gait and balance. Medical treatment is highly successful early on, though the majority of people experience significant complications in later stages. In advanced PD, when medications no longer adequately control motor symptoms, deep brain stimulation offers a powerful therapeutic alternative. DBS involves the surgical implantation of one or more electrodes into specific areas of the brain, which modulate or disrupt abnormal patterns of neural signaling within the targeted region. Outcomes are often dramatic following DBS, with improvements in motor function and reductions motor complications having been repeatedly demonstrated. Given such robust responses, emerging indications for DBS are being investigated. In parallel with expansions of therapeutic scope, advancements within the areas of neurosurgical technique and the precision of stimulation delivery have recently broadened as well. This review focuses on the revolutionary addition of DBS to the therapeutic armamentarium for PD, and summarizes the technological advancements in the areas of neuroimaging and biomedical engineering intended to improve targeting, programming, and overall management.

What Is Parkinsons Disease Surgery


Parkinson’s disease surgery is a brain operation called deep brain stimulation . The surgery is also used to treat epilepsy, obsessive-compulsive disorder and a condition called “essential tremor.” DBS is widely considered one of the most significant neurological breakthroughs in recent history, posing a potential treatment for major depressive disorder, stroke recovery and addiction. Parkinson’s disease brain surgery aims to interrupt problematic electrical signals from targeted areas in the brain and reduce PD symptoms.

Am I A Candidate For Surgery

If you have PD, you should consider surgery when your medicine becomes insufficient in controlling your symptoms, if you experience severe ups and downs , or if your tolerability of the medication is poor and you develop side effects, including dyskinesias . You should not consider surgery if you have severe depression, advanced dementia, or an unstable medical condition, or if you have symptoms that are atypical for PD and that may represent atypical parkinsonism or Parkinson’s plus, such as progressive supranuclear palsy or multiple system atrophy. It is important to understand that surgery will not eliminate your need for medication it will help make your symptoms less severe so that lower doses may be used.

Before determining whether surgery is an option, your condition will be thoroughly evaluated and assessed. A neuropsychologist will assess your thinking and memory and a neurologist will review your current medication regimen and evaluate your physical condition using the Hoehn and Yahr scale and the Unified Parkinson Disease Rating Scale , which examine:

  • mentation, mood, and behavior
  • motor complications
  • Surgery For Parkinsons Disease: Deep Brain Stimulation And Lesioning

    When we refer to surgery in Parkinsons disease it usually refers to Deep Brain Stimulation .Deep Brain Stimulation involves placing a wire with electrodes at its tip into one of three target sites in the brain – the thalamus, the globus pallidus or the subthalamic nucleus. A few days after they are connected to an implantable pulse generator . This small unit is inserted under the skin on the chest wall. When the IPG is turned on the electric pulses stimulate the target area and produce a change in the Parkinsonian symptoms..

    Before DBS was introduced in the 1980s the only operation available for Parkinsons disease involved selectively damaging certain cells in the thalamus and the gobus pallidus called ‘lesioning’. While this sometimes relieved symptoms the damage was irreversible and the operation was risky. With DBS the insertion of the electrodes can be checked to confirm that they have been sited correctly and there are further opportunities for fine tuning through the IPG. The technical advances which have made this operation possible have been the development of CT and MRI scanning which allow the surgeon to locate the target site with great accuracy. While it is not essential, it is usual for the electrodes to be inserted with the patient awake so that they can provide evidence that the target has been reached.

    Deep Brain Stimulation Surgery And Implantation

    DBS consists of two surgeries, spaced approximately three to six weeks apart to ensure the patient has adequate time to recover. Throughout your experience, you will be attended to by a top team of physicians and other medical experts including a neurosurgeon, an electrophysiologist, and an anesthesiologist.

    It should be noted that DBS offers many benefits. The generator can be programmed by a neurologist, and customized to each individual patient. The procedure is also reversible. Most patients experience a significant improvement of symptoms. However, as with any brain surgery, there are risks. With DBS, the risk of stroke is 1 in 100 and infection is 1 in 50.

    Today, many more patients could be helped by DBS than are currently benefiting from the procedure. Statistics show only 7 percent of Parkinsons disease and 1 percent of tremor patients in Michigan who would benefit from the procedure have undergone DBS. At U-M, we are proud to have one of the superior DBS programs in the country. We have developed a wide array of ways to improve DBS, including special imaging tools that help doctors more accurately place the electrodes, and lead intraoperative motor and speech testing that result in fewer side effects for the patient.

    U-M is also home to an active research program, where our team of experts is always working on ways to make DBS faster and more accurate. We also regularly have clinical trials available for patients interested in participating.

    Benefits And Side Effects

    Using Deep Brain Stimulation Surgery to Help Ease Parkinson’s Symptoms

    FUS is a less invasive approach than others doctors do not need to make incisions or holes in the skull, meaning there is a lower risk of infections and bleeds. The procedure is also incredibly precise, limiting damage to surrounding parts of the brain.

    Currently, a doctor may only use FUS for the treatment of tremors due to Parkinsons. Clinical trials are investigating the potential benefits of FUS in targeting other areas of the brain to help treat symptoms such as dyskinesias.

    A person can usually return home the same day as the procedure, but they may experience some side effects such as numbness in the face or arms, poor balance, and speech and swallowing problems. However, these side effects tend to be temporary.

    Deep Brain Stimulation For Parkinsons Disease

    For people with severe motor symptoms of Parkinsons disease that are not adequately controlled by medication, a treatment called deep brain stimulation may offer some relief.

    Deep brain stimulation requires the surgical placement of a small conductor called an electrode in the brain. The electrode delivers electrical stimulation that blocks the nerve signals that cause tremors.

    Specialists at NYU Langones Center for Neuromodulation perform more than 100 deep brain stimulation procedures each year. Our neurologists, neurosurgeons, and psychiatrists provide a thorough evaluation to ensure youre a good candidate for the procedure.

    Living With A Stimulator


    Once the DBS has been programmed, you are sent home with instructions for adjusting your own stimulation. The handheld controller allows you turn the stimulator on and off, select programs, and adjust the strength of the stimulation. Most patients keep their DBS system turned on 24 hours day and night. Some patients with essential tremor can use it during the day and turn off the system before bedtime. Your doctor may alter the settings on follow-up visits if necessary.

    If your DBS has a rechargeable battery, you will need to use a charging unit. On average charging time is 1 to 2 hours per week. You will have a choice of either a primary cell battery or a rechargeable unit and you should discuss this with you surgeon prior to surgery.

    Just like a cardiac pacemaker, other devices such as cellular phones, pagers, microwaves, security doors, and anti theft sensors will not affect your stimulator. Be sure to carry your Implanted Device Identification card when flying, since the device is detected at airport security gates.

    What Is Brain Surgery For Parkinsons Disease

    Brain surgery for Parkinsons disease is done to balance the activity in certain areas of the brain that control physical movement. The surgery can involve placement of a stimulator device or creation of a surgical lesion in the brain.

    The areas of the brain that are affected by Parkinsons disease are very small, and they are located deep within the brain. These procedures are done with precision and often with imaging guidance so your surgeon can see the structure of your brain with real-time pictures during the surgery.

    What It Feels Like: Deep Brain Stimulation For Parkinson’s Disease

    Emma Jones,

    Manzil Bacchus was diagnosed with Parkinsons disease in 2008. Initially, he was told that there was nothing he could do to stop the progression of the progressive nervous system disorder that affects movement. Manzil and his wife, Sadia, continued to manage the increasingly worrisome symptoms which included tremors and the growing amount of medication that he had to take each day.

    After Manzil was diagnosed with colitis, a chronic digestive disease that has been linked to Parkinsons, the family began investigating a new surgical option. In deep brain stimulation , electrodes are inserted in regions of the brain that have been affected by the Parkinsons, with an impulse generator battery also inserted in another area of the body. When turned on, the electrodes send gentle electrical pulses to help improve symptoms like tremors and motor control.

    Manzil and Sadia sat down with Healthing to talk about Manzils experience having brain surgery during the COVID-19 pandemic and the difference that deep brain stimulation has made to his quality of life.

    When was Manzil diagnosed with Parkinsons?Manzil: Back in 2007, my hands started shaking. I was volunteering at a mosque, helping people to take a pilgrimage in Saudi Arabia, helping with their application for visas and stuff like that. One of the girls noticed my hand shaking and asked why. I thought I was just tired. After that, I also noticed that my left foot was dragging when I walked.

    What Is Deep Brain Stimulation

    Deep brain stimulation is a surgical procedure that involves implanting electrodes in the brain, which deliver electrical impulses that block or change the abnormal activity that cause symptoms.

    The deep brain stimulation system consists of four parts:

    • Leads that end in electrodes that are implanted in the brain
    • A small pacemaker-like device, called a pulse generator, that creates the electrical pulses
    • Extension leads that carry electrical pulses from the device and are attached to the leads implanted in the brain
    • Hand-held programmer device that adjusts the devices signals and can turn the device off and on.

    In deep brain stimulation, electrodes are placed in the targeted areas of the brain. The electrodes are connected by wires to a type of pacemaker device placed under the skin of the chest below the collarbone.

    Once activated, the pulse generator sends continuous electrical pulses to the target areas in the brain, modifying the brain circuits in that area of the brain. The deep brain stimulation system operates much the same way as a pacemaker for the heart. In fact, deep brain stimulation is referred to as the pacemaker for the brain.

    What Are The Advantages Of Deep Brain Stimulation

    Parkinson’s Disease Treatment in Hyderabad With Deep Brain Stimulation Surgery (DBS)

    Deep brain stimulation has many advantages:

    • DBS does not cause permanent damage in any part of the brain, unlike thalamotomy and pallidotomy, which surgically destroy tiny areas of the brain and therefore is permanent and not reversible.
    • The electrical stimulation is adjustable and reversible as the person’s disease changes or his or her response to medications change.
    • Because DBS is reversible and causes no permanent brain damage, use of innovative not-yet-available treatment options may be possible. Thalamotomy and pallidotomy result in small, but permanent changes in brain tissue. A person’s potential to benefit from future therapies may be reduced if undergoing these procedures.
    • The stimulator can also be turned off at any time if DBS is causing excessive side effects without any long-term consequences.

    What Are The Risks

    As with any surgery, there are risks associated with deep brain stimulation. If you have DBS, you have about a 3% risk of seizure, infection and confusion. Parkinson’s disease deep brain stimulation also carries a small chance of stroke. Once the neurotransmitter device is turned on, you may experience side-effects such as numbness, muscle tightness, tingling sensations balance problems or mood changes these can be managed with help from your doctor.

    Your doctor will work with you to assess your Parkinsons disease and surgery eligibility and discuss the advantages and disadvantages of this treatment route. If you have any questions, do not hesitate to run them past your treatment provider or call the National Parkinsons Foundation helpline on 1-800-4PD-INFO for more information.
