Who Is A Candidate For Deep Brain Stimulation
DBS is more than just a surgical procedure. It involves a series of evaluations, procedures, and consultations before and after the actual operation, so people interested in being treated with DBS should be prepared to commit time to the process.
For example, those who do not live close to a medical center that offers DBS surgery may need to spend significant time traveling back and forth to appointments.
The procedure, as well as the pre-operative evaluation and post-operative follow-up, can be expensive depending on the persons insurance coverage. DBS surgery is an FDA-approved treatment for Parkinsons disease, and Medicare and most private insurers cover the procedure, but the extent of coverage will depend on each persons individual policy.
Prospective patients should have realistic expectations about DBS results. Although DBS can improve movement symptoms of Parkinsons disease and greatly improve quality of life in properly selected patients, it is not likely to return anyone to perfect health.
What Are The Results
Pallidotomy and thalamotomy Preliminary studies demonstrate that symptom improvement lasts several years in most patients. Because PD is progressive, however, some of your symptoms may return, and other symptoms might appear after surgery.
Other surgical options can be discussed if your symptoms reappear however, this is determined individually based on the location and size of the old lesion/stimulation, the nature of symptom recurrence, and your general medical health.
DBS of the thalamus Studies have shown that this procedure may significantly reduce tremor in about two-thirds of PD patients. Tremor may not be eliminated and may continue to cause some impairment.
DBS of the globus pallidus This procedure is most useful in treatment of dyskinesias as well as other tremors. With DBS of the GPi, patients experience on average a 33% improvement in symptoms during “off” state and 26% improvement during “on” state . Their medication “on” time increased from 28 to 64% .
DBS of the subthalamic nucleus This procedure has an effect on most of the motor features of PD, including bradykinesia, tremor, and rigidity. With DBS of the STN, patients experience on average a 51% improvement in symptoms during “off” state and 25% improvement during “on” state. Their medication “on” time increased from 27 to 74% .
Treatment For Parkinsons Disease
A multidisciplinary team that includes a neurologist and therapists who specialise in movement disorders is recommended for the management of the complex PD symptoms.
The appropriate multidisciplinary team members should be seen from the time the diagnosis of PD is received.
The advancement in the treatment options for PD over the last few decades has meant the progression of disabilities can be slowed and a good quality of life maintained. The following is an overview of current treatments that have good evidence to support their effectiveness.

The availability of surgical procedures on national health services varies from country to country, and even from region to region, so you will need to check locally. Make sure you also check on the provision of any follow-up care or further surgery that may be needed.
Costs vary from country to country so, again, you should check locally. Depending on the country you live in, some costs may or may not be paid by the state.

What Are Surgery Options For Parkinsons Disease
Depending upon your needs, medical history, health, and symptoms, one of the following procedures may be considered for Parkinsons disease:
There are many other procedures being researched. One of the most promising involves the transplantation of fetal dopamine neurons into the brains of people with Parkinsons disease. The hope is that these cells will be able to re-grow the damaged dopamine-producing nerve cells.
Surgery For People With Parkinsons Disease
Deep brain stimulation surgery is an option to treat Parkinsons disease symptoms, but it is not suitable for everyone. There are strict criteria and guidelines on who can be a candidate for surgery, and this is something that only your doctor and you can decide. Surgery may be considered early or late in the progression of Parkinsons.
When performing deep-brain stimulation surgery, the surgeon places an electrode in the part of the brain most effected by Parkinsons disease. Electrical impulses are introduced to the brain, which has the effect of normalising the brains electrical activity reducing the symptoms of Parkinsons disease. The electrical impulse is introduced using a pacemaker-like device called a stimulator.
Thalamotomy and pallidotomy are operations where the surgeon makes an incision on part of the brain. These surgeries aim to alleviate some forms of tremor or unusual movement, but they are rarely performed now.

A Better Understanding Of Parkinsons Disease
Even though we hear more and more about Parkinsons disease, it is sometimes difficult to fully understand it. Lets try to demystify it together. After all, a better understanding often leads to better help!
What is Parkinsons disease?
Parkinsons disease is a neurodegenerative disease. In other words, it is characterized by the progressive destruction of certain neurons in our brain. To be more precise, the destroyed neurons cause a decrease in dopamine. All of this has the consequence of affecting the proper control of movements. It is in this way that a progressive appearance of the main symptoms can be observed such as tremors, slowness of movements and rigidity.
Understanding the causes
The exact causes of Parkinsons disease are still unknown. However, research on this disease continues and tends to show that a combination of several factors could be involved in the development of Parkinsons.
Here is a small list of the risk factors identified:
Although there are forms of the disease that can affect young people, the likelihood of developing Parkinsons disease increases with age. Thus, people aged 60 and over are the most at risk. It is therefore best to remain vigilant when symptoms appear.

What Surgical Treatments Are Available And What Do They Involve
The most common surgical procedure is deep brain stimulation . This surgery has three possible surgical targets in the brain: the thalamus, the globus pallidum internus , and the subthalamic nucleus .
DBS uses implanted electrodes to stimulate either the STN or the GPi. The electrical stimulation that these electrodes produce disrupts the abnormal brain activity which causes movement problems and so improves these symptoms. The stimulator can be adjusted or switched off as necessary.
For more information on other surgical techniques that are being researched, including Gene therapy and Stem cell therapy, see Surgical therapies.
Telemedicine Sensors And Mobile Apps
Given the difficulties some patients with PD have when it comes to traveling and planning office visits, the increasingly accepted field of telemedicine may offer a solution. Many patients have reported preferring telemedicine because they feel more at ease in the comfort of their own home. Remote medical communications in many forms can be especially valuable to patients with PD. However, remote communication requires tools in order to evaluate the patient who is not physically present at the office.
Some sensor modalities are biopotential-specific sensor units, such as electrocardiography and electromyography , motion sensor units, such as accelerometers and gyroscopes and environmental sensor units such as video cameras. Technology solutions to PD remote medical visits include remote tracking of medication use and assistive technologies that directly compensate for disease-related challenges. The same sensors will quantify the effectiveness of medication and rehabilitation therapies.
Smartphone apps designed for PD patients are now available to address different aspects of patients needs. These apps are mainly designed to record and track the data gathered by the sensors already available on most smartphones, such as memory games, finger tapping, speaking, and walking. Ahead is a short list of apps designed for those with Parkinsons disease:

Parkinsons Disease And Preparing For Surgery
People with Parkinsons disease sometimes face procedures or surgeries due to other medical conditions not related to PD. These could be relatively simple procedures such as a colonoscopy or endoscopy, common surgeries such as cataract removal, gall bladder removal or hernia repair, or more complex surgeries such as open-heart surgery or transplant surgery. I am frequently asked about specific concerns that arise when contemplating surgery for someone with PD.
People with PD, as well as people with other brain disorders, are more prone to side effects from anesthesia as well as negative effects from the stress of the surgery itself. Its important to remember that not everyone is affected in the same way, and this doesnt mean people with PD cannot have the surgeries and procedures they need. It is however important to be educated about what potential problems may arise so that you are as prepared as you can be.
Evaluation Of Patients For Stereotactic Surgery
Good surgical outcomes from stereotactic surgery for Parkinson’s disease begin with careful patient selection and end with attentive, detail-oriented postoperative care. The authors believe that this level of care is best provided by a multidisciplinary team comprising a movement disorder neurologist, a neurosurgeon who is well versed in stereotactic technique, a neurophysiologist, a psychiatrist, and a neuropsychologist. Additional support from neuroradiology and rehabilitation medicine is also important. But, as a European-based survey revealed, having the proper clinical support is only one of the challenges that stereotactic surgery for PD faces. There are also issues of regulatory, technical, scientific, and intellectual property rules as well as public perception challenges that have to be overcome.
In addition to being medically evaluated, patients are evaluated for surgery in the movement disorder centers by a neurologist, a neurosurgeon/neuro-radiotherapist, and a psychiatrist/psychologist.
A neurologist with expertise in movement disorders evaluates the patient to assure they are a good candidate for a successful subthalamic nucleus deep brain stimulation to confirm a diagnosis of idiopathic PD, positive response to levodopa, absence of atypical parkinsonian features, and assess the advancement of disease as unmanageable with dopaminergic medications. Other requirements include:

How Does Deep Brain Stimulation Work
During the DBS surgery, leads are implanted on targeted brain areas and a battery-operated medical device called a neurostimulator is implanted in the chest. The DBS system delivers electrical stimulation to targeted areas in the brain that control movement, thereby blocking the abnormal nerve signals responsible for causing tremor and other symptoms of parkinsons disease.
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:

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.
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.

Over the last 70 years, the surgical treatment of Parkinsons disease has made significant advancements in techniques and technology as well as facilitated a better understanding of the pathophysiology of the disease. Since the 1940s, over 8,000 articles have been published on the surgical management of PD . The initial surgical management of PD was limited to lesioning procedures over time, however, particularly in the last 25 years, deep brain stimulation has become the predominant therapy. Current surgical indications for PD include reducing motor fluctuations, off time, dyskinesias, tremor, and levodopa-responsive symptoms, although there has been significant interest in expanding the scope of these surgical treatments.
What Are The Complications Of Parkinson Disease
Parkinson disease causes physical symptoms at first. Problems with cognitive function, including forgetfulness and trouble with concentration, may arise later. As the disease gets worse with time, many people develop dementia. This can cause profound memory loss and makes it hard to maintain relationships.
Parkinson disease dementia can cause problems with:
- Speaking and communicating with others
- Problem solving
- Paying attention
If you have Parkinson disease and dementia, in time, you likely won’t be able to live by yourself. Dementia affects your ability to care of yourself, even if you can still physically do daily tasks.
Experts don’t understand how or why dementia often occurs with Parkinson disease. Its clear, though, that dementia and problems with cognitive function are linked to changes in the brain that cause problems with movement. As with Parkinson disease, dementia occurs when nerve cells degenerate, leading to chemical changes in the brain. Parkinson disease dementia may be treated with medicines also used to treat Alzheimer’s disease, another type of dementia.
