What Will A Cure For Parkinson’s Look Like
Parkinson’s varies so much from person to person. There are over 40 symptoms of Parkinsons. Tremor. Pain. Hallucinations. Everyones experience is different.
Because of this, there may not be a single ‘cure’.
Instead we may need a range of different therapies to meet the needs of the individual and their specific form of the condition.
This mix may include treatments, therapies and strategies that can:
- slow or stop the progression of the condition
- replace or repair lost or damaged brain cells
- control and manage particular symptoms
- diagnose Parkinson’s at the earliest possible stage.
And this could involve medical treatments, such as drugs and surgical approaches, as well as lifestyle changes, for example to diet and exercise.
Medical Treatment Of Parkinsons Disease
Enormous progress has been made in the treatment of Parkinsons disease over the past half century, but levodopa remains the most potent drug for controlling PD symptoms . Prior to instituting medical therapy, a correct diagnosis of PD must be established and the level of impairment determined . Each patients therapy is to be individualized, and diverse drugs other than levodopa are presently available. Among these are the dopamine agonists , catechol-o-methyl-transferase inhibitors and nondopaminergic agents . Head-to-head comparisons of drugs within classes are rare, and the differences that have emerged are related to the effects on motor fluctuations, dyskinesias, on/off times and adverse effects of the specific agents within each class .

What Is Parkinsons Disease
Parkinsons disease is a progressive brain disorder that causes shaking and muscle stiffness, and slows movement. It develops when neurons in a particular part of the brain stop working properly and are lost over time. These neurons produce an important chemical called dopamine. Dopamine is used by the brain to send messages across brain areas to help control movement. Eventually, the brain cannot make enough dopamine to control the movement properly.1,2
What Are Surgery Options For Parkinson’s Disease
Depending upon your needs, medical history, health, and symptoms, one of the following procedures may be considered for Parkinson’s 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 Parkinson’s disease. The hope is that these cells will be able to re-grow the damaged dopamine-producing nerve cells.

What Are Off Episodes
Firstly, its important to understand what OFF episodes are and why they happen. OFF episodes are defined as a temporary returning of Parkinsonian symptoms such as tremor, rigidity, loss of postural reflexes and memory problems, while taking levodopa medication. OFF episodes affect the majority of people with PD, and it can occur at any stage of the illness.
Some patients experience OFF episodes when they first wake in the morning known as akinesia while others notice symptoms returning at the end of a dose when the drug starts to wear off. For some, the OFF episodes are random and severe. Uncontrolled Parkinson’s symptoms can significantly impact your quality of life, which is why scientists are committed to finding new and improved treatment options.
The Impact Of Remotely Supervised Tdcs On Parkinsons Disease And Other Neurological Conditions
NYU Langone researchers are also looking into the benefits of RS-tDCS for other neurological conditions in several open-label studies.
A study conducted in collaboration with researchers at the , slated for publication in the Journal of NeuroEngineering and Rehabilitation, demonstrated the applicability of this methodology in Parkinsons disease, with improvements in fatigue and cognition similar to those seen in MS. Further, as published in 2018 in the Journal of Clinical Neuroscience, patients with moderate Parkinsons disease experienced a notable reduction in symptoms from using RS-tDCS in combination with cognitive training.
The use of telemedicine to supervise at-home tDCS will allow us to reach more patients and also to bypass common obstacles that prevent populations with mobility impairment or other accessibility barriers from participating in clinical trials and receiving health services, says Milton C. Biagioni, MD, assistant professor of neurology and coinvestigator on the study. This is the first time an RS-tDCS protocol has been designed for and tested in these patients.
According to study coinvestigator Milton C. Biagioni, MD, telemedicine allows people who have mobility impairments to access healthcare services and clinical trials.
Although studies currently focus on patients with moderate Parkinsons disease, researchers at the Fresco Institute anticipate expanding these investigations in the near future to include patients with advanced disease.

New Parkinsons Disease Treatments
The interventions that were presented are not entirely new, and they are not highly available.
Duodopa is a gel form of Levodopa delivered with use of an external pump and tubing, directly to the stomach and small intestine. It involves a minor surgical procedure, takes 45 minutes to perform and does not require a hospital stay.
There are only 5 centres in Ontario offering this intervention. This intervention has been successful in eliminating the extremes of on and off periods of medication effectiveness and has been associated with an improved quality of life and social functioning for patients.
Deep Brain Stimulation was described as a pacemaker for the brain. It involves the placement of an electrode in the brain attached to a small device inserted under the skin, below the collarbone. Just as with the Duodopa therapy, patients who receive this intervention enjoy less dyskinesia and improved quality of life and social functioning.
There was a lot of discussion around best candidates. The presenters defined best candidates as having:
The speaker addressed the question of a transdermal patch to deliver medication apparently it is available, just not very effective.
What Is Fetal Cell Transplantation
Fetal cell transplantation is a procedure in which fetal cells are implanted into the brains of people with Parkinson’s disease to replace the dopamine-producing cells in the substantia nigra. Although promising, this area of research is one of the most controversial. Some studies have found that fetal cell transplantation caused an increase in severe involuntary movements due to too much dopamine in the brain. There are also moral and ethical objections to the use of fetal cell implants. As a result, other methods of treatment are being explored.

Top Ways To Treat Parkinsons Disease
This content was developed in partnership with the Parkinsons Foundation.
Every person living with Parkinsons disease experiences symptoms, disease progression and treatments that are unique to them. There is no single treatment plan that works for everyone.
The most common way to treat and manage PD symptoms include medications, exercise, rehabilitation therapies and surgical procedures. Treatment plans should be tailored to respond to an individuals symptoms and personal circumstances. While there is currently no cure for PD, the goals of treatment are to minimize symptoms and improve overall quality of life.
Risk Factors For Parkinsons Disease
The cause of Parkinsons remains unknown, but several factors can contribute to its development, including a family history of the disease. Men are more likely to develop Parkinsons, and most people develop the disease around age 60 or older, although in 10% of cases it can begin as early as age 40.

Medication For Parkinsons Disease
Once the doctor diagnoses Parkinsons disease, the next decision is whether a patient should receive medication, which depends on the following:
-
The degree of functional impairment
-
The degree of cognitive impairment
-
Ability to tolerate antiparkinsonian medication
-
The advice of the attending doctor
No two patients react the same way to a given drug, therefore, it takes time and patience to find an appropriate medication and dosage to alleviate symptoms.
Advanced And Future Treatments For Parkinsons
While theres no cure for Parkinsons disease, recent research has led to improved treatments.
Scientists and doctors are working together to find a treatment or prevention technique. Research is also seeking to understand who is more likely to develop the disease. In addition, scientists are studying the genetic and environmental factors that increase the chance of a diagnosis.
Here are the latest treatments for this progressive neurological disorder.
In 2002, the FDA approved deep brain stimulation as a treatment for Parkinsons disease. But advances in DBS were limited because only one company was approved to make the device used for the treatment.
In June 2015, the FDA approved the

The Latest Treatment For Parkinsons Disease
Inbrija is the latest treatment for Parkinson’s disease. It was approved by the Food and Drug Administration in late 2018 after two decades of research and development. Inbrija is a new form of levodopa that allows systemic delivery of the medication through inhalation, allowing higher doses of medication to enter the bloodstream.
This new drug from Acorda Therapeutics will treat the intermittent symptoms of OFF episodes on demand and comes in the form of a powder capsule and inhaler. Inbrija is the first and only inhaled levodopa medication to be approved for Parkinsons disease by the FDA. It is available by prescription through your doctor.
The Michael J. Fox Foundation helped to fund the early development of this new treatment for Parkinson’s disease due to the impact OFF periods have on patients’ lives.
Parkinsons Disease Treatment Options
Parkinsons is incurable, but the symptoms can be managed as the disease progresses. Initially, your doctor may recommend lifestyle changes, such as ongoing aerobic exercise, healthy diet, and advice for avoiding falls.
Medication
-
Carbidopa-levodopa : Sometimes simply called Levodopa, is the most effective Parkinsons disease medication and has been since its breakthrough in the late 1960s. It is an effective first-line treatment for Parkinsons and comes in many formulations, including slow- and extended-release pills, and infusions. It works by introducing a natural chemical to the body which converts into dopamine in the brain. This helps reduce symptoms of stiffness and tremors. The medication does not slow the progression of the disease.
-
Catechol O-methyltransferase inhibitors: These pills can boost the effectiveness of carbidopa-levodopa. It helps block the brains dopamine breakdown to help reduce some of the tremors and motor symptoms of Parkinsons.
-
Dopamine agonists: This medication mimics the effect of dopamine in the brain and may be used with carbidopa-levodopa. It can be prescribed in the early stages of Parkinsons, and it can lengthen the effectiveness of carbidopa-levodopa.

Parkinsons Treatment On The Horizon
Immunotherapy: Researchers at the Columbia University Medical Center and the La Jolla Institute for Allergy and Immunology have found evidence that autoimmunityin which the immune system attacks the bodys own tissuesplays a role in Parkinsons disease. The findings raise the possibility that the death of neurons in Parkinsons could be prevented by therapies that dampen the immune response.
Our findings raise the possibility that an immunotherapy approach could be used to increase the immune systems tolerance for alpha-synuclein, which could help to ameliorate or prevent worsening symptoms in Parkinsons disease patients, says study co-leader Alessandro Sette, Dr. Biol. Sci., professor in the Center for Infectious Disease at La Jolla Institute for Allergy and Immunology in La Jolla, Calif. The study was published in Nature.
The idea that a malfunctioning immune system contributes to Parkinsons dates back almost 100 years, said study co-leader David Sulzer, PhD, professor of neurobiology at CUMC. But until now, no one has been able to connect the dots. Our findings show that two fragments of alpha-synuclein, a protein that accumulates in the brain cells of people with Parkinsons, can activate the T cells involved in autoimmune attacks.
This is the strongest evidence we have so far that a drug could do more than provide symptom relief for Parkinsons disease, says the studys senior author, Professor Tom Foltynie .

Restoration Of Dopaminergic Deficits
Treatment of many of the motor symptoms of PD can be achieved through restoration of striatal dopaminergic tone. This may be accomplished through targeted delivery of dopamine-producing cells, or the use of viruses to deliver genes encoding the enzymes required for dopamine biosynthesis into the striatum. Targeting these regenerative treatments to the striatum, the site of greatest dopamine loss in PD, would minimize the off-target effects seen with oral dopamine-replacement.
Researchers Are Getting Closer To A Drug That Is Truly A Parkinsons Treatmentone That Can Halt Or Cure The Disease Instead Of Just Fighting Symptoms
As the incidence of Parkinsons growsan estimated 50,000 new cases per yearso do the options being offered by drug manufacturers.
Todays Parkinsons treatment options address the symptoms of tremors, stiffness, and slow movement to improve quality of life. However, they do little to slow the progression of this disease. Fortunately, research is helping us better understand Parkinsons. While early signs of Parkinsons disease can be overlooked, once its diagnosed, treatment options are expanding beyond the current drugs. So one day we may find a Parkinsons treatment that makes the disease less of a life sentence.
If you have Parkinsons disease, there arent any treatments that can slow, reverse, or stop the conditions progression, says Kara J. Wyant, M.D., in a Michigan Health blog on Parkinsons treatment. But, although there is no cure, more than a dozen medications can help patients manage symptoms. Our goals when prescribing medications for Parkinsons disease are twofold: to improve day-to-day functioning and quality of life and to keep people functioning as long as possible.

What We Know So Far
- We’ve uncovered clues to the causes and genetic involvement in Parkinson’s.
- We’re figuring out the chain of events that leads to the damage and loss of brain cells.
- We’re working to advance new treatments and therapies.
- We’re exploring repurposing drugs to help manage some of the more distressing symptoms, like hallucinations and falls.
- And we know that, although people with Parkinson’s share symptoms, each person’s experience of the condition and response to treatment is different.
Now, the science is ready for us to develop the new treatments and cure that people with Parkinson’s so desperately need.
Research takes time but if you have Parkinsons, you need better treatments now. Thats why weve launched the Parkinson’s Virtual Biotech to speed up the most promising potential treatments. The more we can invest, the sooner we’ll get there.
Important Points About The New Medications
With multiple new medications available for the treatment of PD, there is more hope than ever that Parkinsons symptoms can be successfully managed for many years. A few things to consider:
- For people whose symptoms are difficult to control, these new treatments are welcome additions to what was previously available and many people with PD have been using these new medications with significant benefit.
- On the other hand, many of the newly-approved medications have the same mechanisms of action as older medications so they are not breaking new ground in treating symptoms.
- In addition, for some people, the effect on symptoms may be mild or not substantial.
These caveats may mean that your physician has not suggested a medication change for you. It is also important to note that despite all the new medications, carbidopa/levodopa remains the most potent medication to treat the motor symptoms of PD.
If your doctor does choose to try one of the new options, there may be multiple paths that your doctor can take when contemplating a medication adjustment. Often trial and error is the only way to determine the best medication regimen for you, so you may need to practice some patience as you work together with your doctor to determine what works or doesnt work.
