What Is Dbs Surgery For Parkinson’s Disease

Healing And Care After Surgery

Role of DBS Surgery for Parkinson Disease today – Parkinson Symposium 2016

Most people spend a day or two at the hospital. Healing may take several weeks. You will have pain medications for any discomfort you may have at the incision sites.

While healing, avoid strenuous activities and heavy lifting. Don’t raise your arms above your shoulders, and don’t bend or stretch your neck excessively. As always follow your doctor’s instructions.

Your doctor will help you decide when you’re ready to return to activities and will turn your device on at your first programming session a couple weeks after your surgery.

How Does Dbs Compare To Other Methods Of Treatment For Parkinsons Disease

As in Hardys case, every patients treatment begins with medication until it is determined that they can benefit from DBS. Medications are always tried first. Unfortunately, we can only get so far with medications. Oftentimes, many patients try them, and they may work for a little while, said Dr. Sheth.

But at some point, oftentimes the medications stop working as much because the disorder tends to progress over the years. It could get worse, and the medicines may not be able to keep up. Many of the medicines themselves have their own side effects. So, you get to a point where perhaps the medicines are helping to a degree, but they’re causing their own side effects, and exactly when we get to that point is when we introduce the idea of a surgical therapy like DBS.

Pros Of Deep Brain Stimulation

  • Symptom Reduction: DBS often reduces symptoms significantly. These include motor symptoms like stiffness, tremor, slowness and dyskinesia. DBS has also been shown to aid in on/off fluctuations, improve mood and quality of life, and increase overall energy level.
  • Little to No Damage: In contrast to previous methods, DBS does not damage portions of the brain, nor remove nerve cells.
  • Utilizing DBS in addition to levodopa could decrease a persons need for medication, thus, decreasing medication access and cost issues, as well as levodopa side effects.
  • Individualized Treatment: Electrodes and stimulation frequency and intensity can be controlled by physicians and the individual with DBS, and can be subjectively altered when needed.

Who Is A Candidate

You may be a candidate for DBS if you have:

  • a movement disorder with worsening symptoms and your medications have begun to lose effectiveness.
  • troubling “off” periods when your medication wears off before the next dose can be taken.
  • troubling “on” periods when you develop medication-induced dyskinesias .

DBS may not be an option if you have severe untreated depression, advanced dementia, or if you have symptoms that are not typical for Parkinson’s.

DBS can help treat many of the symptoms caused by:

  • Parkinson’s disease: tremor, rigidity, and slowness of movement caused by the death of dopamine-producing nerve cells responsible for relaying messages that control body movement.
  • Essential tremor: involuntary rhythmic tremors of the hands and arms, occurring both at rest and during purposeful movement. Also may affect the head in a “no-no” motion.
  • Dystonia: involuntary movements and prolonged muscle contraction, resulting in twisting or writhing body motions, tremor, and abnormal posture. May involve the entire body, or only an isolated area. Spasms can often be suppressed by “sensory tricks,” such as touching the face, eyebrows, or hands.

After your evaluation and videotaping is complete, your case will be discussed at a conference with multiple physicians, nurses, and surgeons. The team discusses the best treatment plan for each patient. If the team agrees that you are a good candidate for DBS, you will be contacted to schedule an appointment with a neurosurgeon.

What Happens During The Surgery

Deep Brain Stimulation at Two Different Targets Produces ...

The surgery is generally carried out in two stages. First, a local anesthetic is applied to the scalp before surgery and very fine wires are inserted into the brain at the targeted region.

The second stage may be carried out under general anesthesia. A wire is implanted to connect the electrodes to a neurostimulator, which generates the electrical pulse that is delivered by the electrodes. The neurostimulator is generally implanted below the collarbone, but can also be placed in the lower chest.

Once the device has been implanted, the symptoms can be monitored and the setting of the neurostimulator can be adjusted to best suit the patients needs. Re-programming is noninvasive because it can be performed wirelessly using an antenna held near the site of the neurotransmitter.

Why A Doctor May Choose Deep Brain Stimulation

According to the National Parkinson Foundation, the ideal Parkinsons disease candidate for DBS surgery has:

  • PD symptoms that interfere with activities of daily living.

  • Fluctuations in mobility due to PD medications with or without dyskinesia .

  • Continued good response to PD medications, even if the medication effects may wear off sooner than they have in the past.

  • A history of several different combinations of PD medications while under the supervision of a neurologist specializing in movement disorders.

These factors* may make a person a less than ideal candidate for DBS surgery:

  • Difficulty with balance, walking, or freezing as the main disabling symptom.

  • A primary symptom of speech difficulty.

  • Continuous confusion and problems with memory and thinking.

  • A psychiatric condition such as depression or anxiety that has not improved or stabilized with other treatment.

  • Another condition that increases the risk for surgery complications.

*Some of these factors may be treatable. Having one or more does not disqualify a person for future DBS surgery, but the doctor may recommend more aggressive therapy focused on these issues before surgery takes place.

How Is The Surgery Performed

UPMC was one of the first centers to use ROSA robotic assistance for the placement of DBS electrodes. ROSA is similar to a GPS device for the brain. It provides the surgeon with a roadmap to reach the intended brain targets. The patient is sedated for the beginning of the surgery while we make a small opening in the skin and bone at the surgical site. The patient will not feel or remember this part of the surgery, but once these steps are complete, he is awoken for the remainder of the surgery.

Brain MappingWe use neurophysiology recordings from very thin electrodes inserted into the brain to map activity in the intended target and confirm the best spot for the DBS electrode. It is important for the patient to be awake during this part of the surgery so we can obtain the best recordings possible, which will aid in the most accurate placement of the DBS electrode. The brain mapping is not painful and the surgical team will be available to provide reassurance and feedback the entire time.

Intra-Operative Stimulation TestingWhen the best site is identified from the brain mapping, the DBS electrode is inserted and tested. We monitor the patient for improvement in his symptoms, for example tremor, and also ask him to report any new sensations he experiences. Again, this part of the procedure is not painful, but provides valuable feedback to the surgical team.

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.

Very Adjustable As Per The Situation:

Less Consumption Of Daily High Dose Medicine:

Hopefully, caregivers of people know that PD people need to take different doses of medicine to control the symptoms of Parkinsons.

Initially, Pd people dont face many side effects of the medicine. After certain years, they get severe side-effects of medication. After DBS surgery quantity of medicine will be reduced.

The biggest issue that keeping track of multiple medicines can be difficult. DBS therapy helps to reduce the amount of medication.

Who Should Get Deep Brain Stimulation

This is a common question with a surprisingly simple answer: Anyone who would get significant benefit from the treatment and can undergo the operation with minimal risk. It is not necessary to suffer for years after diagnosis, trying every known combination of medicine, before DBS can be considered. DBS is a surgical option that is known to improve quality of life for patients with movement disorders, so when ones quality of life is dramatically affected by the disease or by medication side effects, its time to consider DBS.

What Happens During The Dbs Procedure

Most DBS procedures are performed with the patient awake under local anesthesia, with their head immobilized in a rigid frame, so that the surgical team can monitor patient response to the electrode placement as it occurs. A few centers are now offering image-guided placement, in which the surgery is performed under general anesthesia without the frame. The pulse generator is usually implanted during a second surgery, scheduled about a week after the first.

Testing Before Deep Brain Stimulation

Parkinsons disease

For patients with Parkinsons disease, the doctor must confirm that the PD is levodopa-responsive and determine which symptoms are most likely to respond to DBS and discuss these with the patient.

To accomplish these two objectives, the movement disorders neurologist will examine the patient in the absence of his or her PD medications, then again after having taken them. Seeing the effect of PD medications on the movement and non-motor symptoms helps the physician and patient identify good target symptoms for DBS.

A cognitive assessment can help determine a persons ability to participate in the procedure, which involves providing feedback to the doctor during surgery and throughout the neurostimulator adjustment process. This assessment also informs the team of the risk of having worsened confusion or cognitive problems following the procedure.

Some hospitals also perform an occupational therapy review or speech, language and swallowing assessment. A psychiatrist may examine the person to determine if a condition such as depression or anxiety requires treatment before the DBS procedure.

Stereotactic Dbs Vs Interventional Image

Stereotactic DBS surgery requires the patient to be off their medication. During the procedure, a frame stabilizes the head and provides coordinates to help the surgeons guide the lead to the correct location in the brain. The patient gets local anesthesia to keep them comfortable throughout each step along with a mild sedative to help them relax.

During image-guided DBS surgery, such as with interventional MRI or CT scan, the patient is often asleep under general anesthesia while the surgeon uses images of the brain to guide the lead to its target.

Some advanced centers offer both the stereotactic and iMRI-guided options for DBS surgery. In this case, the doctor and patient will discuss which procedure is better based on a number of factors.

For instance, the doctor may recommend an image-guided procedure for children, patients who have extreme symptoms, those who are especially anxious or fearful or those whose leads are going into certain parts of the brain.

Generally, DBS surgery follows this process:

Regulatory Approval & Reimbursement

The Exablate system manufactured by is approved in Europe and in the US for treating tremor-dominant Parkinsons disease. Patients should talk with their physician if they are not sure if they have tremor-dominated Parkinsons disease. We recommend that they talk with the treatment site for questions about insurance coverage under Medicare, as some treatment sites are now being reimbursed by Medicare. Most commercial companies are not currently covering this procedure.

Dbs For Parkinsons Disease

If you or someone you love has Parkinsons, you may know that deep brain stimulation surgery is an option. But you might not know that DBS is not just for advanced Parkinsons. It can be part of your Parkinsons treatment plan early, so discuss this option with your neurologist.

OHSU is an international leader. Our neurosurgeon, Dr. Kim Burchiel, was not just the first physician to do DBS in the United States he was the first to offer patients “asleep” DBS while the patient is under general anesthesia. This site explains what DBS is, how it works and if you might be a candidate. It also tells you how DBS is done at OHSU and why you dont have to be awake during the procedure.

How Is The Blood

Before and After video of patients who had DBS surgery for Parkinson’s disease

The patient is fitted with a specialized headframe, which directs ultrasound waves to precise targets in the brain. The patient is then placed in an MRI for the focused ultrasound treatment.

An ultrasound contrast agent, or microscopic bubbles, are injected intravenously and circulate in the bloodstream. These microbubbles are smaller than red blood cells when low-intensity focused ultrasound energy is applied the circulating microbubbles vibrate, temporarily expanding the junctions between the cells of the BBB.

The small and temporary opening in the BBB created by focused ultrasound, allows the direct delivery of the enzyme replacement therapy. In this Phase 1 trial, the putamen is the region targeted for enzyme delivery because of its key functions in Parkinson disease and role in motor performance.

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!

What Care Is Needed After

On top of the wound care required with any surgery, DBS calls for special follow-up and ongoing care. Depression, falls, nausea, and problems with motor skills and swallowing can occur after DBS. In a follow-up appointment, doctors can address these issues and any other side effects of the device and/or the stimulation.1,2

Some follow-up care will last only a short time, depending on the issue. For instance, DBS can alter a persons mood, personality, and speech. Counseling, drugs, and speech therapy may help with these issues. A doctor can help find the best course of action in each case.1,2

People treated with DBS will need some extra care for the rest of their lives. Each persons device must be maintained and adjusted to meet their unique needs. Dosages of other drugs used to treat PD may also need to change over time.1,2,4

Why Would You Be Recommended For Dbs

DBS is used for the treatment of motor symptoms in Parkinsons disease, such as tremor, rigidity, stiffness, slowed movement and walking problems. It is generally only offered to patients who have had Parkinsons disease for at least four years and after other avenues of medication have been tried and failed to fully control the symptoms. These patients may be those who experience a significant off time or have severe dyskinesia as a result of long-term levodopa usage.

Deep Brain Stimulation For Movement Disorders

Components of Deep Brain Stimulation System

Deep brain stimulation has been approved for the treatment of movement disorders since the 1990s. Numerous studies have proven this surgerys superiority to medical therapy alone. The time to consider DBS surgery is when the quality of life is no longer acceptable on optimal medical therapy as administered by a movement disorder specialist. DBS surgery is very safe and recent advancements in device technology have improved patient outcomes as well.

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.

Improves Quality Of Life Of Parkinsons People:

I hope that you have gone through this line, you must have got one line in your mind that all above mention benefits are leading to give good quality of life.

Improved quality of life includes other aspects as well as, such as emotional well-being, better social life, having less physical discomfort.

I guess that Parkinsons people caregivers are looking for all these qualities in the PD people.

Is This A Cure For Parkinsons Disease

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.
