Deep Brain Stimulation for Parkinson’s Disease

Programming the neurostimulator takes place a few weeks after surgery. The settings vary by patient and are set by your neurologist. One question is how much control if any, the patient wants over the settings.

Ive had some neurologists that did not want the patient to have the option of changing the settings. Ive had others who do not hesitate to give the patient some degree of control. I want to be involved in my therapy and to have the capacity to change my settings if needed.

Having the DBS surgery has made a significant difference for me and greatly improved my quality of life. I am thankful that this therapy is available to those with PD and am excited to see what future advancements are made in neurostimulators.

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.

How Effective Is Dbs

In randomized clinical trials, DBS has proven to be more effective than continued medical management alone. For patients with Parkinsons disease, DBS has been shown to remarkably increase the amount of on time with good symptom control, and many patients are able to reduce their medications significantly after the surgery.

Post-operation, the DBS electrical current can be turned off if needed and fine-tuned for optimal symptom control using a wireless programmer.

As with any surgery, there are risks and potential complications, but this surgery is well-tolerated for the vast majority of patients.

Weighing The Risks And Benefits

First, did I need DBS? After all, this is brain surgery. And while minimal, there are some serious risks. One is reminded of this when meeting with their neurosurgeon. A brain hemorrhage due to surgery is one risk with permanent brain damage being the result.

I had to weigh this against the benefits of the surgery. For me, the primary benefit is less dyskinesia due to a reduction in the amount of Levodopa I was taking. My dyskinesia was called biphasic dyskinesia since I experienced it right after my Levodopa “kicked in” and when it was wearing off.

It became so debilitating that there were times when I needed a wheelchair to get around. After conferring with my neurologist and neurosurgeon I decided to have the surgery.

What Are The Benefits Of Deep Brain Stimulation

DBS provides good benefit for certain symptoms . Importantly, fluctuations usually improve a lot in response to DBS, since the stimulation goes on in an uninterrupted fashion. Although patients typically still need to take medication after undergoing DBS, they can often reduce their dosages so much that side effects improve substantially. Other symptoms, including balance problems, falls, and often speech impairment, may not respond favorably to DBS surgery.

Unlike older types of surgery for Parkinson’s disease, DBS does not involve intentional destruction of brain tissue. The jamming signal from DBS is adjusted as an outpatient to provide the patients with the optimal symptom relief. Also, as the patient’s condition changes, the pulse generator device can easily be re-programmed. Further surgery is not needed until the battery in the chest is replaced, typically three to five years later.

Power Savings And Adaptive Effect

The mean total electrical energy delivered with aDBS was significantly less than that with cDBS , so that the better improvements in clinical score were achieved with less than half the total electrical energy delivered. Similarly, when averaged over the whole block of stimulation, aDBS was only on 44.2 ± 2.4% of the time. This was well matched by random DBS, which was on 43.3% ± 1.5% of the time .2). Moreover, time on stimulation tended to progressively drop during stimulation in the aDBS mode. This was despite the use of a fixed beta threshold, suggesting that beta bursts became less frequent over the course of aDBS. The mean correlation coefficient between percentage stimulation time over each 10 seconds and total duration of DBS up to that point was 0.23 across subjects . This correlation was also individually significant in 3 of the 8 cases .

Decline in triggered stimulation duration over time. Dependency of proportion of time stimulated on duration of adaptive deep brain stimulation is shown for Subject 5. Solid and interrupted lines are result of linear regression and 95% confidence intervals, respectively. r = 0.567, p< 0.001.

How Deep Brain Stimulation Works

What is Deep Brain Stimulation for the treatment of Parkinson’s disease?

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.

Mechanism Of Action Of Dbs

Current hypotheses on the action mechanism of DBS include depolarization blockade , synaptic inhibition , synaptic depression , stimulation-induced disruption of pathological network activity , and stimulation of afferent axons projecting to the STN . Depolarization blockade and synaptic inhibition are likely to explain the similarity between the therapeutic benefit of DBS and lesional surgery. Recordings of decreased somatic activation in the stimulated nucleus favor these hypotheses . However, the increased output of projection neurons does not seem to be mediated by these phenomena . Another and currently favored hypothesis is that DBS overrides abnormal spike train patterns by an unphysiological, high-frequency pattern, and thereby masks pathological signals, which cause dysfunction of the remaining elements of the basal ganglia-thalamo-cortical and brainstem motor loop . The exact nature of the abnormal signals and the interaction between stimulation-induced neuronal responses and intrinsic brain activity remains elusive, but abnormalities of the firing rate and pattern of basal-ganglia neurons, changes in oscillatory activity and excessive synchronization at multiple levels of the motor loop have been proposed as pathophysiological correlates of motor symptoms in PD .

What Is Deep Brain Stimulation Surgery

Deep brain stimulation is a therapy most often used to treat symptoms of Parkinsons disease, including tremor, rigidity, stiffness, slowed movement and walking problems. DBS is also used to treat essential tremor, dystonia, Tourette syndrome and obsessive/compulsive disorder .

How does DBS surgery work?

DBS involves implanting a device about the size of a stopwatch under the skin of the chest. The device delivers electrical stimulation to the brain through a thin insulated wire that connects to electrodes placed in the skull. DBS stimulates specific areas of the brain to treat and improve debilitating tremors and Parkinsons symptoms. Essentially, DBS is a brain pacemaker.

What is deep brain stimulation treatment for Parkinsons disease?

Because Parkinsons disease is considered a chronic and progressive disease, symptoms worsen over time. Parkinsons symptoms may include:

  • physical tremor of hands, arms, legs, jaw and face
  • slowness of movement

What are the benefits of DBS?

Deep brain stimulation has helped people remain in their careers, care for their families, resume favorite activities and once again do simple things in daily life. Clinical studies have shown that deep brain stimulation surgery, when added as treatment for Parkinsons disease, can:

What To Expect After Dbs

Surgery to implant the leads generally entails an overnight stay, while the IPG is usually implanted as same-day surgery. During recovery, your surgeon will talk to you about caring for your wounds, when you can shower, and any activity restrictions. Its usually recommended that any heavy lifting be avoided for a few weeks.

After another two to four weeks, youll return to have your device programmed. This process will continue for several weeks to ensure the stimulation settings are optimal to control your symptoms. During these visits, you will be shown how to turn the device on and off with the handheld device and check the battery level.

Once the programming has been completed, you will have regular follow-up visits to check and adjust the stimulation to maintain the most benefit for your symptoms.

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

Risks And Side Effects Of Deep Brain Stimulation

Like any surgery, deep brain stimulation can have side effects, and it carries potential risks. Its also important to consider the complications and side effects of medications you take since their dosages can often be reduced following surgery.

While DBS may cause side effects, it may also reduce side effects from medications.

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.

How Is Deep Brain Stimulation Used To Treat Parkinsons Disease

Deep brain stimulation delivers electrical impulses to a targeted area of the brain that is responsible for the movement symptoms caused by Parkinsons disease. The electrical impulses disrupt the abnormal activity that occurs in the brains circuitry, which is causing the symptoms.

There are three areas in the brain that can be targets for deep brain stimulation in patients with Parkinsons disease. They are the subthalamic nucleus, the globus pallidus internus, and the ventral intermediate nucleus of the thalamus. Each of these areas plays a role in the brains circuitry that is responsible for the control of movement.

The specific area in the brain to target in an individual with Parkinsons disease depends on symptoms that need to be treated. For example, deep brain stimulation of subthalamic nucleus is effective for all major movement symptoms of Parkinson’s disease, such as tremor, slowness of movement , stiffness , and problems with walking and balance. Deep brain stimulation of globus pallidus is another effective target for a wide range of Parkinson’s symptoms. The thalamic target is sometimes selected for patients with tremor symptoms. The recommended target for each patient is made collaboratively with the neurologist, neurosurgeon and other caregivers involved in the decision making process.

What Happens During The Procedure

In the operating room, your scalp will be injected with numbing medication. Your head will be placed in a frame to keep it from moving. Small holes will be drilled into your scalp to allow the implantation of electrodes.

Youll be awake during surgery so you can respond to questions and move particular areas of your body when prompted. This, along with imaging tests, helps pinpoint the areas of the brain where symptoms originate. This is where electrodes will be placed.

Electrodes may be implanted on one or both sides of your brain. The neurostimulator will be implanted under the skin near your collarbone or lower in your chest. Leads will go underneath your skin from head to shoulder, connecting the electrodes to the neurostimulator. The tiny holes in your skull will be closed.

After surgery, youll be monitored for complications. Youll spend at least 24 hours in the hospital, but longer if you have complications.

Some risks of surgery are:

  • bad reaction to anesthesia
  • allergic reaction to materials in the implanted device
  • pain or swelling at the surgical site
  • infection
