Will I Have To Limit My Activity Following Deep Brain Stimulation Surgery

  • You should not engage in light activities for 2 weeks after surgery. This includes housework and sexual activity.
  • You should not engage in heavy activities for 4 to 6 weeks after surgery. This includes jogging, swimming, or any physical education classes. Anything strenuous should be avoided to allow your surgical wound to heal properly. If you have any questions about activities, call your doctor before performing them.
  • You should not lift more than 5 lbs. for at least 2 weeks.
  • You should not raise your arms above your shoulders or over bend or stretch your neck.
  • Depending on the type of work you do, you may return to work within 4 to 6 weeks.

How Is Deep Brain Stimulation Surgery Performed

Identifying the brain target: Before the procedure is done, the exact target brain areas where electrical nerve signals generate PD symptoms, are identified with the help of Magnetic Resonance Imaging or Computed Tomography scanning or microelectrode scanning.

How is DBS surgery performed?

Surgery: The surgery involves two stages:

  • First stage: Thin wires or electrodes are placed into the specific target area of the brain. The patient is kept awake to perform certain tasks to ensure that the electrodes are positioned correctly.
  • Second stage: On the same day or next day,the electrodes are connected to a battery-operated device called impulse generator battery or neurostimulator, by an insulated wire passing under the skin of the head, neck and shoulder. The neurostimulator is then implanted under the skin below the collarbone.

Programming: The IPG is turned on and adjusted 2-4 weeks after surgery and may take a few weeks before patients receive adequate symptom relief. The patient receives initial programming of the neurostimulator so that it delivers continuous electrical pulses through the electrodes. These impulses interfere with and block the electrical signals that cause PD symptoms. All parts of the stimulator system are located internally. Patients may also receive a hand held device to check battery and switch on and off the device.

Selecting The Type Of Dbs Surgery

There are two types of DBS surgery.

  • Awake DBS : Awake DBS uses a metal frame that is secured to your head. This keeps your head steady and allows us to accurately identify the structure of your brain. You then have an MRI or CT scan so we can see the frame in relation to the brain. We then plug the coordinates of the frame into our sophisticated GPS system. After we place a microelectrode into the spot we want the DBS electrode to go, we can listen to the cells in your brain to make sure that were in the right place. Once we confirm this, we will replace the microelectrode with the DBS electrode. We then test the electrode to make sure it relieves your symptoms without side effects. Then you get a CAT scan to make sure the DBS electrode is in place. There should be no pain during this surgery. Numbing medicine is used. You are awake but sometimes a little sleepy. Your family can even be present during frame placement if you like.

  • Asleep DBS: At the University of Michigan, we can now do DBS in an MRI scanner. The computer software in the MRI shows us our target. Then in real time, we can watch the electrode being placed in the MRI to make sure its going to the right place. The rest of the procedure is pretty much the same as awake brain surgery.

How Do I Know If Im A Candidate For Deep Brain Stimulation

Before being considered a candidate for deep brain stimulation , patients with Parkinsons disease must undergo an extensive evaluation process. Ideally, a multidisciplinary team of specialists in the area of movement disorders will assess the patient. This clinical team typically includes a neurologist, neurosurgeon, neuropsychologist and psychiatrist.

If patients are well managed on medications, DBS is not considered. Candidates for DBS are patients who meet one or more of the following criteria:

  • Symptoms are not well controlled despite receiving the appropriate dose of levodopa and other medications.
  • Symptoms are significantly reducing patients quality of life.
  • Abnormal or uncontrolled involuntary movements or motor fluctuations are not improving despite adjustments in medications.
  • Four or more doses of levodopa are required a day.
  • Tremors that have not been able to be controlled by medications.

Levodopa response test

Patients response to a single dose of levodopa is another test physicians use to identify which patients are likely to benefit from DBS. In this test, patients stop taking levodopa for 8 to 12 hours and then receive a single dose. Patients are likely to benefit from DBS if they have a clear positive response after receiving the single dose of levodopa.

Why The Uf Health Center For Movement Disorders And Neurorestoration For Dbs

Deep Brain Stimulation at Two Different Targets Produces ...

The UF Health Center for Movement Disorders and Neurorestoration is an international leader in the use of DBS implants for treating Parkinson disease and other movement disorders. The program is supported by the National Institutes of Health and several other funding agencies, and performs cutting edge research. The FDA has approved DBS for the treatment of Parkinsons disease, Essential Tremor, and certain . Use of DBS in other disorders is an active area of research here at UF .

The UF Health Center for Movement Disorders and Neurorestoration is the only center in North America that brings total care for movement disorders together in one location. The CMDNR was established at the Evelyn F. and William L. McKnight Brain Institute in July 2002, to bring together UF doctors and researchers with special expertise in Parkinsons disease and other movement disorders. The mission of the center is To provide the highest level of medical and surgical care to patients with Parkinsons disease, tremor, dystonia and other movement disorders. To perform research that will lead to better treatments and ultimately cures for Parkinsons disease and other movement disorders.

How Dbs Can Help Parkinsons

DBS helps smooth the effect of the medications so you have less off time and fewer peak-dose dyskinesias, or involuntary muscle movements. DBS wont make you any better than the medications do, but it will give you more hours of the day in which your medications work well.

After DBS surgery, some patients find that they can reduce the amount of medication they are taking sometimes by as much as 50 percent.

The ideal DBS candidate has a diagnosis of PD, symptoms not controlled by medication , no dementia and no significant untreated depression.

It might be time to consider it when youre starting to have issues with your medications and youre having a lot of dyskinesias and wearing-off times.

Its also better to have DBS surgery when youre younger. The older you are, the higher the risk of complications.

What Happens After Surgery

After surgery, you may take your regular dose of Parkinson’s medication immediately. You are kept overnight for monitoring and observation. Most patients are discharged home the next day.

During the recovery time after implanting the electrodes, you may feel better than normal. Brain swelling around the electrode tip causes a lesion effect that lasts a couple days to weeks. This temporary effect is a good predictor of your outcome once the stimulator is implanted and programmed.

About a week later, you will return to the hospital for outpatient surgery to implant the stimulator in the chest/abdomen. This surgery is performed under general anesthesia and takes about an hour. Patients go home the same day.

Step 7: implant the stimulator You will be taken to the OR and put to sleep with general anesthesia. A portion of the scalp incision is reopened to access the leads. A small incision is made near the collarbone and the neurostimulator is implanted under the skin. The lead is attached to an extension wire that is passed under the skin of the scalp, down the neck, to the stimulator/battery in the chest or abdomen. The device will be visible as a small bulge under the skin, but it is usually not seen under clothes.

You should avoid arm movements over your shoulder and excessive stretching of your neck while the incisions heal. Pain at the incision sites can be managed with medication.

What Are The Benefits

It is believed that the electrical signals generated by DBS in the brain that causes the issues with motor control.

DBS is not a cure for Parkinsons disease, nor does it stop the progression of the disease, but many patients experience a significant reduction in their symptoms following surgery. Most patients will still need to take medication after the surgery, but DBS may lead to a reduction in the amount required. This in turn can reduce medication-induced side effects, such as dyskinesia.

How Do I Know If I Am Eligible For Treatment

Your doctor is the best person to ask about this. He or she will be able to tell you if you are a suitable candidate. In general, people who cannot go into an MRI will not be able to go through the treatment this includes patients with metallic implants, patients who are claustrophobic and patients who are allergic to contrast agents a dye used during MR imaging, patients who are over 300 lbs and patients who are under 22 years of age.

  • If you have any kind of metallic implants, such as pacemakers, neurostimulators, spine or bone fixation devices, total joints, metal clips, screws, etc., you may not be a candidate. Any metallic implants must be non-magnetic to prevent injury to the patient from the MRs strong magnetic field.
  • If you are not generally healthy enough to withstand the treatment and lie still in the same position for approximately 3 hours, you may not be a suitable candidate for this treatment.
  • If you have had a recent myocardial infarction or have congestive heart failure , unstable angina pectoris , or spinal conditions, are you should discuss these issues with your doctor.
  • If you have extensive scarring on the scalp, you may not be a good candidate.
  • If you have any tumors inside the skull, you may not be a good candidate.
  • If you are on dialysis, you may not be a good candidate.
  • If you have an active infection or severe hematological, neurological or other uncontrolled disease, you may not be a good candidate.

 

Is This A Cure For Parkinsons Disease

No.

This current research trial is investigating the safety of injecting an enzyme in conjunction with opening the BBB in the putamen, one of the key regions of the brain implicated in Parkinsons. The putamen is a key structure in controlling the brains motor circuitry.

The hope is that this technique may be a way to open temporary access ports into the brain and allow large molecules such as enzyme therapies to enter.

This Phase 1 clinical trial is a very early, but necessary step in this process.

How Has Deep Brain Stimulation Benefitted Patients With Parkinsons Disease

Healthy Tips & Resources

Dr. Sameer Sheth, neurosurgeon at Baylor St. Lukes Medical Center, uses deep brain stimulation as an alternative to medication for treating disorders such as Parkinsons disease and essential tremor. DBS involves placing a device called a neurostimulator that sends electrical impulses through implanted electrodes to specific targets in the brain.

What Are The Dbs Surgery Risks

Although this is surgery on the brain, as compared to other surgeries, it is relatively minor. Therefore the DBS surgery risks are low. But they are not non-existent.

Let us look at one of the largest studies on this topic, to know the DBS surgery risk.

A group of German researchers studied 1,183 patients who had Deep Brain Stimulation surgery. This series included patients with Parkinsons disease as well as with other diseases. These were their findings.

  • The risk of death was less than 1%. 
  • About 2% of patients had bleeding inside their head that caused weakness on one side of the body. In many patients, this weakness resolved by itself within 30 days.
  • A few patients had uncommon problems such as infection.
  • A few patients had somewhat unrelated problems such as pneumonia.
  • In short:

    • More than 95% of patients did not have any complications.
    • The risk of death or permanent problems was minimal .

    Overall, as previously mentioned DBS surgery risks are modest. They are on the lower side of those expected from a major surgery.

    Perhaps more important is to consider the long-term side effects of the electrical stimulation itself.

    Low Intensity Focused Ultrasound To Help Deliver Therapies

    Components of Deep Brain Stimulation System

    While high intensity FUS is a treatment for PD as described above, low intensity FUS can be used in an entirely different way to help treat PD. This type of FUS may allow for disruption of the blood brain barrier. The blood brain barrier refers to the cells that line the blood vessels within the brain which keep foreign substances, such as toxins and microbes, in the bloodstream and out of the brain.

    Normally, this mechanism is advantageous and protects the brain. However, the blood brain barrier may also keep out molecules that could help to treat brain diseases. Therefore, disrupting the blood brain barrier could allow for penetration of these molecules into particular areas of the brain. A whole variety of different molecules such as antibodies, nerve growth factors and gene therapy may be able to take advantage of this approach. Further research is necessary to determine if this will be a useful method for drug delivery into the brain.

    Focused Ultrasound Has Potential As A Non

    Aug 3, 2020

    Most people with Parkinsons will use medication to help control their symptoms, but for some, over time, medications alone may no longer be enough to control symptoms. This is when specialists may look towards surgical options. Currently deep brain stimulation offers the main surgical way to control movement symptoms of Parkinsons.

    This type of surgery involves inserting fine wires into the brain to be controlled by a pulse generator that is placed under the skin around the chest or stomach area. When the pulse generator is switched on, the electrodes deliver high frequency stimulation to the targeted area. This stimulation changes the electrical signals in the brain that are causing some of the movement symptoms of Parkinsons.

    Read more about the brief history of surgery for Parkinsons in a previous blog post.

    But what if there was another way to target cells deep within the brain? This is where a technique called focused ultrasound comes in. It offers a way to change the way the brain works without the need for invasive brain surgery.

    In this blog we find out exactly what focused ultrasound is and how it might help people with Parkinsons in the future.

    To learn more, we spoke to Professor Wladyslaw Gedroyc, Consultant Radiologist at Imperial College Hospital, who has over 20 years experience investigating the potential of focused ultrasound.

    Benefits Of Deep Brain Stimulation Treatment For Parkinsons Disease

     When you decide to undergo DBS surgery, the first question that comes to mind that what are the benefits of Deep Brain Stimulation Treatment for Parkinsons disease. Is Deep Brain Stimulation surgery going to change my lifestyle?

    Answer: Yes.

    Hopefully, you are familiar with the term DBS surgery. Many of us are thinking that what is DBS?

     If you dont know then let me say that DBS stands for Deep Brain Stimulation.

    DBS is an elective surgical process that involves implanting electrodes into certain brain areas. In the brain, which delivers electrical impulses that control abnormal brain activity.

    The best part of this stimulation system is that you can adjust to chemical imbalances in the brain. Let me give you a basic idea of Deep Brain Stimulation.

    Benefit For Sleep And Appetite

    Many patients who have undergone DBS have expressed that after surgery, they are able to sleep better.

    The reason for this is that the severity of the OFF period reduces and the patient is having more comfort whilst sleeping.

    The overall well-being and the direct stimulation effect of DBS also help in appetite improvement and most patients put on weight after surgery!

    How Deep Brain Stimulation Works

    Exactly how DBS works is not completely understood, but many experts believe it regulates abnormal electrical signaling patterns in the brain. To control normal movement and other functions, brain cells communicate with each other using electrical signals. In Parkinson’s disease, these signals become irregular and uncoordinated, which leads to motor symptoms. DBS may interrupt the irregular signaling patterns so cells can communicate more smoothly and symptoms lessen.

    What Are The Advantages Of Deep Brain Stimulation

    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 Happens During Surgery

    For stage 1, implanting the electrodes in the brain, the entire process lasts 5 to 7 hours. The surgery generally lasts 3 to 4 hours.

    Step 1: attach stereotactic frameThe procedure is performed stereotactically, which requires attaching a frame to your head. While you are seated, the frame is temporarily positioned on your head with Velcro straps. The four pin sites are injected with local anesthesia to minimize discomfort. You will feel some pressure as the pins are tightened .

    Step 2: MRI or CT scanYou will then have an imaging scan, using either CT or MRI. A box-shaped localizing device is placed over the top of the frame. Markers in the box show up on the scan and help pinpoint the exact three-dimensional coordinates of the target area within the brain. The surgeon uses the MRI / CT scans and special computer software to plan the trajectory of the electrode.

    Step 3: skin and skull incisionYou will be taken to the operating room. You will lie on the table and the stereotactic head frame will be secured. This prevents any small movements of your head while inserting the electrodes. You will remain awake during surgery. Light sedation is given to make you more comfortable during the initial skin incision, but then stopped so that you can talk to the doctors and perform tasks.

    Research To Improve Deep Brain Stimulation

    Researchers are working to improve upon existing DBS devices and methods to help treat more symptoms and more people. Some researchers are putting electrodes in a different area of the brain the pedunculopontine nucleus to treat walking and balance problems that don’t typically improve with present-day DBS. Others are developing a “smart” DBS device that can record a person’s unique brain signals and deliver electrical stimulation only when needed, such as when symptoms return, rather than continuously, as the current systems do. This could help reduce side effects such as numbness and weakness and lengthen the battery life of the neurostimulator, which would result in a longer time between battery replacement procedures.

    Scientists also are planning to test deep brain stimulation in the first years after a Parkinson’s diagnosis to see if the therapy may slow or stop disease progression. Testing in Parkinson’s models showed the therapy may help protect brain cells, and a small human trial showed motor symptoms improved after early-stage DBS.

    What Kind Of Results Can You Expect After Having Dbs

    Frontiers

    A few weeks after the surgery, a specialist will program the DBS settings to your symptoms.

    DBS wont eliminate symptoms, but more than 70 percent of people with Parkinsons experience a significant improvement.

    Youll likely be able to cut back on medication. DBS settings can be adjusted without surgery. It may take a few months to find the best combination of medications and DBS settings.

    How Effective Is Deep Brain Stimulation For Parkinsons Disease

    Deep brain stimulation provides excellent relief for most patients symptoms including tremor, stiffness , slowed movement , freezing of gait and dyskinesias. Long-term studies have shown continued improvement in tremor, bradykinesia, and dyskinesia. Many patients are able to reduce their medications and maintain their level of function including independent participation in activities of daily living required to care for oneself. One of the distinct advantages, is that after DBS, patients on average improve their daily on timewhen they are at their best, without troublesome dyskinesiaby half a day.

    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.

    Best Benefit Of Dbs Surgery To Treat The Symptoms Of Movement In Parkinsons Disease:

    DBS treats most of the movement-related symptoms, e.g. Tremors, Rigidity , slowness, etc. associated with PD

    Patients with Advanced Parkinsons disease start suffering from all the above symptoms that affect their quality of daily living.

    Many patients complain of change in handwriting, unable to sign, perform fine motor tasks, and requiring assistance to do some of the daily activities.

    Some of the patients complain that they are not able to enjoy their life completely, as they would wish to, e.g. someone would like to do a Social Service, someone may want to play golf, others may want to go out and meet friends, all these activities are significantly impaired as the disease progresses.

    Most of the time the medical treatment offers good relief however as the disease progresses this relief is short-lived and irregular.

    Patients find that the medicines are not effective all the time and every time. Patients also feel that the medical effect cannot be sustained for a prolonged period and hence they become scared about venturing out on their own.

    They start becoming dependent and start isolating themselves from society. This has a negative effect on the psychology of the patient making the patient more and more depressed. This cycle has to be brain broken. 

    Deep Brain stimulation surgery is the best option to break the cycle as it restores most of the functions of patients that are disabled because of Parkinsons disease and also gives them a smooth quality of on period.

    The Device Works For 24 Hours

    DBS Therapy works 24 hours a day with nominal maintenance. DBS therapy does not require removal at night, cleaning, refilling, etc.

    This provides stimulation equally at any time.

    Final Point for Benefits of Deep Brain Stimulation Treatment For Parkinsons Disease

    To conclude _____ let me summarise the benefits of DBS. Deep Brain Stimulation therapy done at the right time in the right patient can offer significant control of the motor symptoms of patients with Parkinsons disease.

    Motor symptoms are the major handicap as the disease advances and improvement in this symptom translates into significantly improved quality of life.

    Activities of daily living significantly improved, medications reduce, general wellbeing improves along sleep and appetite.

    Deep Brain stimulation surgery should be only done at an experienced center as it is something that requires a high level of surgical expertise, understanding of the disease, and the ability to do effective postoperative management and programming.

     

    For the caregiver the return of the self-esteem, the smile on the face, and the knowledge that their near and dear is now independent; can be the most satisfying and gratifying experience.

    Above all, when you see the smile on their face, it touches your heart. Your near dear is an Independent person.
