What Can Hospice Do For A Patient With A Serious Neurological Disease

Your hospice team evaluates the patients status and updates the plan of care as symptoms and condition change, even on a day-to-day basis. The goal of hospice is to relieve physical and emotional distress so patients can retain their dignity and remain comfortable.

Hospice offers comprehensive services for patients with serious neurological disease:

Intercurrent Illnesses Associated With Neurological Disease Include:

• Pneumonia
• Upper urinary tract infection or other infection, despite antibiotic therapy
• Abnormal/absent brain response, verbal response or withdrawal response to pain

In general, patients who are eligible for hospice are thought to have a prognosis of six months or less if the disease runs its normal course. When improvement is unlikely, or when a decision is made to discontinue a feeding tube or ventilator/breathing support, hospice care should be considered.

VITAS provides these guidelines as a convenient tool. They do not take the place of a physicians professional judgment.

Parkinsons Disease: Criteria Need To Qualify For Hospice Services

The patient must meet the following criteria:

Rapid disease progression and either a or b below:

• Progression from independent ambulation to wheelchair or bed-bound status
• Progression from normal to barely intelligible or unintelligible speech
• Progression from normal to pureed diet
• Progression from independence in most or all Activities of Daily Living to needing major

assistance by caretaker in all ADL

What Is Deep Brain Stimulation How Does Dbs Work

DBS is the short form of Deep Brain Stimulation. DBS is one type of Parkinsons Surgery.

DBS works by passing a small current into the brain. This current is passed into only to a small part of the brain.

The doctor selects one out of two brain parts .

DBS works by changing the electrical currents in these areas. At present, we cannot mathematically calculate these changes.

But, empirically DBS improves Parkinsons symptoms.

Let us learn more about these topics:

• NeuroPlus Epilepsy & Parkinson’s Clinic Dr. Kharkar

Testing Before Deep Brain Stimulation

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.

How Does Dbs Treat Parkinsons

Parkinsons disease causes irregular electrical signals in parts of the brain that control movement. DBS uses electrical stimulation to modulate these control centers deep to the surface of the brain, improving communication between brain cells.

This helps to reduce symptoms such as tremor, slowness, and stiffness. It doesnt have much of an effect on non-motor symptoms or balance issues. Here are some additional tips for improving motor skills with Parkinsons.

DBS is the most commonly performed surgical procedure for symptoms of Parkinsons disease.

DBS isnt a first-line therapy. Its intended for people whose symptoms are still unmanageable even with medication. Learn about other advanced and future treatments for Parkinsons.

You might be a good candidate for DBS if:

• youve had symptoms for at least five years
• your symptoms respond to medication, but the effect doesnt last as long as it used to
• youve tried various doses and combinations of medications
• your symptoms interfere with everyday life

Your doctor is unlikely to recommend DBS if:

• Parkinsons medications havent helped much
• you have memory and thinking problems
• you have anxiety or depression that hasnt stabilized with treatment
• you have dementia

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

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.

Parkinsons Disease Symptoms Creep In

Meanwhile, Craigs health deteriorated. By 2016, his ability to operate equipment that makes full-sized pickups look like Tonka trucks was no longer possible, and he went on disability. Walking became increasingly difficult, to the point that a walker, and, later, an electric wheelchair, came into play. An expert archer and bowhunter, Craig found himself unable to handle his bow. Other activities he loved camping, four-wheeling in the Black Hills, fishing with his grandson Hayden suddenly seemed out of reach. Fatigue and sleep problems, common Parkinsons symptoms, crept in. Making matters worse, the levodopa played havoc with his digestive system.

He couldnt eat, wouldnt eat, Susan recalled.

As so often happens, physical challenges brought psychological barriers, and justifiably. Craig couldnt walk into a store and be entirely sure he would be able to walk back out of it because, as he put it, my muscles would just stiffen up. Craig started skipping his grandsons youth baseball and basketball games games he loved to watch for the same reason. He increasingly ended up watching a lot of TV by himself.

I had no ambition. Things I really enjoyed, I didnt want to do anymore, Craig said.

Susan, working full-time as the treasurer of Weston County, never quite knew what to expect upon returning from work.

Major Depression And Obsessive

DBS has been used in a small number of clinical trials to treat people with severe treatment-resistant depression . A number of neuroanatomical targets have been used for DBS for TRD including the subgenual cingulate gyrus, posterior gyrus rectus,nucleus accumbens, ventral capsule/ventral striatum, inferior thalamic peduncle, and the lateral habenula. A recently proposed target of DBS intervention in depression is the superolateral branch of the medial forebrain bundle its stimulation lead to surprisingly rapid antidepressant effects.

The small numbers in the early trials of DBS for TRD currently limit the selection of an optimal neuroanatomical target. Evidence is insufficient to support DBS as a therapeutic modality for depression however, the procedure may be an effective treatment modality in the future. In fact, beneficial results have been documented in the neurosurgical literature, including a few instances in which people who were deeply depressed were provided with portable stimulators for self treatment.

DBS for TRD can be as effective as antidepressants and can have good response and remission rates, but adverse effects and safety must be more fully evaluated. Common side effects include “wound infection, perioperative headache, and worsening/irritable mood increased suicidality”.

Dbs Valuable For Parkinsons Before Patients Go Over A Cliff

We no longer think about DBS for someone whos already over the cliff and holding on to a blade of grass, Kern said. We want to implement this before weve approached the cliff.

In less metaphorical terms, Kern generally suggests DBS for Parkinsons patients before theyve stressed marriages, lost jobs, or missed time with children and grandchildren that they cant get back.

Mike was missing time with his children. Even with the medications, what were once routine demands at work left him exhausted at home. The seesawing from those meds left him more or less constantly vomiting or falling asleep. Playing with his kids may as well have been marching up a Fourteener.

When Kern suggested DBS, the Whitts were enthusiastic but surprised.

For the longest time, we knew it was an option, Mike said. But I thought it was a last resort, which isnt true.

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 Long Does The Battery In The Impulse Generator Device Last

Batteries can last 3 to 5 years in non-rechargeable devices and up to 15 years or even longer in rechargeable battery devices. However, these times may vary significantly. A simple outpatient procedure is needed to replace the battery. Rechargeable battery devices can be charged daily or every 10 to 14 days . Your doctor will discuss how often you should recharge your battery based on your therapy settings.

Placement Of The Neurostimulator

This procedure takes place under general anesthesia so that the person is asleep. The surgical team inserts the neurostimulator under the outer layers of skin, usually just under the collarbone, but sometimes in the chest or abdomen. The extension wire from the lead is attached to the neurostimulator.

I Have Essential Tremor That Affects My Voice Will Dbs Help The Tremor In My Voice

Although DBS is excellent for helping the tremor that is experienced in the hands and arms due to essential tremor, it is unlikely that DBS will help your voice with just a unilateral lead. Although there may be patients who notice a slight improvement in voice with unilateral stimulation, most notice no improvement. With bilateral stimulation, the voice tremor may improve, but bilateral stimulation will often cause slurred speech as well. Botulinum toxin injections are generally more effective for voice tremor than DBS.

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.

Treating The Movement Symptoms Of Parkinsons

Deep brain stimulation helps control your movement symptoms when your medications aren’t working as well as they used to. For many people with Parkinson’s, DBS makes a difference when even small tasks have become challenging. DBS has helped some people stay as independent as possible and keep doing the activities they love.

What Are The Risks

No surgery is without risks. General complications of any surgery include bleeding, infection, blood clots, and reactions to anesthesia. Complications related to placement of the DBS lead include seizures, infection, and a 1% chance of bleeding in the brain.

Reasons for which you might need additional surgery include breakage of the extension wire in the neck parts may wear through the skin and removal of the device due to infection or mechanical failure. Additionally, the battery will need to be replaced every 2 to 5 years. Some DBS systems have a rechargeable battery that may last up to 9 years.

DBS may also cause worsening of some symptoms such as speech and balance impairments. In some patients with Parkinson’s, DBS may cause or worsen depression. If you develop any side effects from a stimulation adjustment, you need to return to the office for further programming.

I Live Alone Can I Have Dbs

It depends on whether you have family or friends that are available to stay with you for a few days after surgery. Youll also need help with transportation back and forth for your appointments as well as to and from the hospital. We have found that the outcomes from your DBS are better overall if you have someone helping you. If you have willing family and friends who are interested in helping you until you have recovered from your DBS surgery, you should be able to return to living alone.

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 Are The Risks And Complications Of Deep Brain Stimulation

As with any surgical procedure, there are risks and complications. Complications of DBS fall into three categories: surgery complications, hardware complications, and stimulation-related complications.

• Surgical complications include brain hemorrhage, brain infection, wrong location of the DBS leads, and less than the best location of the leads.
• Hardware complications include movement of the leads, lead failure, failure of any part of the DBS system, pain over the pulse generator device, battery failure, infection around the device and the device breaking through the skin as the thickness of skin and fat layer change as one ages.
• Stimulation-related complications occur in all patients during the device programming stage. Common side effects are unintended movements , freezing , worsening of balance and gait, speech disturbance, involuntary muscle contractions, numbness and tingling , and double vision . These side effects are reversible when the device is adjusted.
