The Symptoms That Dbs Treats
Deep brain stimulation is used primarily to treat the motor symptoms of Parkinsons disease, but this can vary somewhat between the different placement sites. Symptoms treated include:
- Abnormal movements : Dyskinesias are often a side effect of medications for Parkinsons disease and include involuntary movements such as twisting, head bobbing, squirming, and more.
DBS is not usually helpful with walking problems or balance, though improvements in the symptoms above can indirectly affect walking. It also does not provide significant benefits for non-motor symptoms of Parkinsons such as cognitive changes, mood changes , or problems with sleeping.
The benefits of DBS can be estimated by looking at how a person responds to levodopa. Symptoms that respond to levodopa will often respond to DBS . But symptoms that are not changed with levodopa are unlikely to be improved by DBS.
DBS often allows for a reduction in the dosage of levodopa, which in turn can result in fewer involuntary movements and a reduction in off time. The result is often improved quality of life.
Percept Pc Dbs System
UChicago Medicine is the first hospital in the Chicagoland area to use the new Percept PC DBS system to treat patients with movement disorders and ranks as the most “Percept experienced” DBS program in all of Illinois.
The Percept PC DBS system not only stimulates the brain, but also takes recordings, allowing us to see how the brain responds to the stimulation. This system represents a new area of individualized treatment for our patients and should provide more symptom relief.
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.

Uw Medicine Neurosciences Institute
Check out Suzanne’s story from her treatment at the UW Medicine Neurosciences Institute . At NSI, we use Deep Brain Stimulation and other innovative technologies to care for patients with neurological conditions such as Parkinsons disease and other complex movement disorders. Our movement disorder neurologist works hand in hand with a neurological surgeon to provide patient-centric, multidisciplinary care that effectively improves symptoms.
What Benefits Does The Procedure Offer
DBS is not a cure for Parkinsons, but it may help control motor symptoms while allowing a reduction in levodopa dose. This can help reduce dyskinesias and reduce off time. DBS does not usually increase the peak benefits derived from a dose of levodopa the best levodopa response before DBS is a good indicator of the best response after DBS. But it can help extend the amount of on time without dyskinesias, which may significantly increase quality of life.
DBS does not provide most patients benefit for their non-motor symptoms, such as depression, sleep disturbance, or anxiety. DBS also does not usually improve postural instability or walking problems. If a symptom you have does not respond to levodopa, it is not likely to respond to DBS.

What Is Parkinsons Disease Surgery
Parkinsons 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. Parkinsons disease brain surgery aims to interrupt problematic electrical signals from targeted areas in the brain and reduce PD symptoms.

Deep Brain Stimulation Surgery
Our physicians are experts in deep brain stimulation surgery. Almost all of our patients undergoing DBS surgery experience a significant reduction in the severity of symptoms. Additionally, our physicians actively research and develop techniques to enhance the effectiveness of DBS surgery.DBS is a complex stereotactic procedure, meaning the neurosurgeon uses a 3D brain mapping system to access and treat precise areas in the brain that are otherwise difficult to reach. In stereotactic procedures, the neurosurgeon operates tiny, specialized surgical instruments through a very small hole in the skull while the patient is awake. This minimally invasive technique maximizes benefit and minimizes risk compared to traditional brain surgery.

What Are The Benefits Of Deep Brain Stimulation Therapy
There are various benefits of the Deep Brain Stimulation procedure. These are:
- Regulatory approved procedure: The Deep Brain Stimulation procedure is approved by various regulatory authorities such as USFDA. Apart from Parkinsons, DBS is authorized to treat essential tremor, dystonia, obsessive-compulsive disorder, and epilepsy.
- Advanced procedure: DBS procedure is an advanced treatment option that improves the overall quality of life of the patient.
- Effective: DBS procedure is quite effective. Approximately 85% of people experience a significant reduction in their Parkinsons symptoms.
- Improves quality of life: DBS improves the quality of life. People began to experience confidence in the public after undergoing DBS. Further, they are less dependent on others for performing daily activities.
- Reduce the dose of medications: The initial treatment of Parkinsons disease is medications. As the conditions progress, the doctor either adds the medications or increases the dose of current medications. However, these medications have side effects. DBS helps in reducing the dose of medications and lowers side effects.
- Adjustable: The DBS is adjustable. As the disease progresses, the surgeon can adjust the strength of impulse without the need for further surgery.
- Reversible: DBS procedure is reversible. If the patient does not require DBS, the surgeon can either cut-off the impulse or remove the complete device.
Less Medication More Relief
Medtronic DBS therapy may reduce the need for other Parkinsons medications1 and, consequently, medication-related side effects. DBS delivers therapy 24 hours a day and doesnt wear off while sleeping. Its already working when you wake up.

What Does Medicare Cover For Home Health Care Services For Patients With Parkinsons Disease
There is no one-size-fits-all answer to this question, as Medicare coverage for home health care services can vary depending on a number of factors. That said, Medicare does generally cover some home health care services for patients with Parkinsons disease, though there may be some restrictions in place. For example, Medicare will typically cover home health care services that are deemed medically necessary for the treatment of Parkinsons disease. This can include things like physical therapy, occupational therapy, and speech therapy. In some cases, Medicare may also cover nursing care and home health aides. However, its important to note that Medicare coverage for home health care services is not unlimited. There may be limits on the number of visits covered, and patients may be responsible for copayments or coinsurance. Additionally, Medicare may only cover home health care services that are provided by Medicare-certified home health agencies. If you or a loved one has Parkinsons disease and is considering home health care, be sure to check with your Medicare plan to see what services are covered.
Ultrasonic beams are focused on specific parts of the brain as part of this procedure, causing specific symptoms to develop. If a person has Medicare, he or she may be able to enroll in a Part D prescription drug plan. Most Medicare Advantage plans include prescription drug coverage as part of the plan.

How Does Dbs Work
In DBS surgery, electrodes are inserted into a targeted area of the brain, using MRI and, at times, recordings of brain cell activity during the procedure. A second procedure is performed to implant an impulse generator battery , which is similar to a heart pacemaker and approximately the size of a stopwatch.
The IPG is placed under the collarbone or in the abdomen and delivers an electrical stimulation to targeted areas in the brain that control movement. Those who undergo DBS surgery are given a controller to turn the device on or off and review basic parameters such as battery life.

Should The Cn Be Avoided During Trajectory Planning
Representation of the CN is well delineated on both T1 and T2 MRI sequences, which are considered standard imaging elements enabling optimal trajectory and target planning during DBS procedures . Clear visualization of the lateral CN borders on MRI allows evaluation of this nucleus during the planning phase. Throughout the years 20002005, our group did not specifically evaluate the interrelationship between planned electrode trajectories and the CN. Currently, we do explicitly evaluate this during trajectory planning for DBS procedures, and this change in surgical approach was induced by recent literature evaluating CN penetration. When evaluating a recent cohort of our institution , the average sagittal and coronal angles of contemporary implantations were 78° and 19°, respectively, compared to 78° and 14° in our historical cohort used for the current study. Strict avoidance of the CN during trajectory planning thus results in a more lateral chosen entry point, which can be expected due to the periventricular localization of the CN. In our recent experience, avoiding the CN during trajectory planning can be well implemented together with choosing an entry point on top of a gyrus and avoiding blood vessels and ventricles.
Life After Dbs Surgery
The days and weeks after DBS surgery for Parkinsons or essential tremor are different for everyone. But here are things to keep in mind:
- Rest: When you return home, rest as much as possible. Slowly return to regular activities.
- Falls: You have an especially high risk of falling in the weeks after DBS. Patients often feel overconfident after surgery. If you used a walker or cane before surgery, keep using it until you are stronger and steadier.
- Symptoms: Your symptoms may improve temporarily after surgery, and its normal for this honeymoon effect to wear off. Your symptoms will improve again as we program your DBS system.
- Time: It may take a few months of adjustments before your DBS system works as well as possible for you.

The Honeymoon Effect After Dbs Surgery
Your symptoms may improve temporarily after surgery. This is called the microlesion or honeymoon effect. It can last days or weeks after your surgery.
You might be tempted to lower your medication dose, but dont change your medications unless recommended by your neurologist.
Dont worry when the effect wears off. Its normal for symptoms to go back to their pre-DBS level. They will improve as your DBS system starts working. It may take a few months of adjustments before your DBS system works as well as possible.
Some people may need physical or speech therapy after DBS to get the best results.
Unilateral Versus Bilateral Surgery
Determination about unilateral or bilateral lead placement is done during preoperative evaluations. Most centers perform bilateral lead placement as a majority of patients have axial and bilateral symptoms. Lead implantation can be performed simultaneously during a single session or in a staged approach with placement of a lead for the most affected side first followed by the contralateral side after several weeks or months. The literature on staged compared to simultaneous approach for lead placement is limited. A staged procedure may potentially reduce the risk of DBS-associated complications and recovery time . However, a retrospective analysis comparing staged and simultaneous approach found no significant difference between 90-day postoperative complications and annualized cost . For older patients or those with predominant one-sided symptoms, unilateral DBS may be considered . Unilateral DBS in either STN or GPi has been shown to improve motor symptoms and quality of life , with a greater benefit with GPi-DBS on quality of life .

Anesthesia Medication And Program
All patients were routinely monitored for non-invasive blood pressure, electrocardiogram, and pulse oxygen saturation after entering the operation room. GA was conducted by tracheal intubation through an oral visual laryngoscope. The induction medication included: methylprednisolone 40 mg, midazolam 12 mg, etomidate 0.10.2 mg/kg, and/or propofol 0.51 mg/kg, rocuronium ammonium 0.50.6 mg/kg, sufentanil 0.20.3 g/kg. All patients underwent continuous invasive radial artery pressure monitoring after intubation. Intravenous inhalation was combined with maintenance anesthesia . Intraoperative fluids were sodium acetate Ringer’s solution and hydroxyethyl starch 130/0.4.
What To Expect After Deep Brain Stimulation
Patients considering deep brain stimulation should have realistic expectations for results. The surgery relieves symptoms, but it is not a cure. It can also take up to six months of adjustments after surgery for some patients to achieve optimal results.
- More than 70 percent of patients with Parkinsons Disease experience significant improvements to their motor function, or how they control their body movements. They may gain up to 4.5 hours of good on time.
- Results can be dramatic in patients with dystonia. Some improvement occurs in 50 to 70 percent of patients.
- In patients with essential tremor, 72 to 85 percent of patients see improvement.

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 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.
About The Dbs Procedure
Deep brain stimulation therapy uses a small, pacemaker-like device to send electrical signals to an area in the brain that helps fine-tune and control movement. The electrical brain stimulation may, in some cases, block some of the brain messages that cause involuntary and disabling motor symptoms. The device is implanted under the skin in the chest. Small, thin wires connect the device to electrodes placed in your skull, allowing the signals to reach the areas of your brain that are causing your symptoms.
After the DBS system is implanted, your expert DBS programmer adjusts the settings to personalize your DBS therapy. You may need several programming sessions to find your optimal settings. The settings can be adjusted in the future if your symptoms change. Most people do not feel the stimulation, though some may sense a brief tingling when the stimulation is first activated.
A few weeks after the procedure, most patients can resume normal daily activities. Your DBS clinician will let you know when you can try activities that had been difficult for you prior to deep brain stimulation surgery.
DBS surgery recovery and healing
Patients are usually able to return home the day after DBS surgery. Healing can take several weeks, and we will give you medication to manage any pain. Typically, we will not activate your device until your first programming session.
