New Treatment For Parkinsons Disease
This fall, the Montreal Neurological Institute and Hospital expects to introduce a previously unavailable form of treatment for Parkinsons disease patients. Although the treatment will be limited to patients who fulfill specific criteria, the treatment has been shown to be effective in Europe, where it has been available for more than a decade.
The treatment involves administering the drug Duodopa directly into the patients small intestine via the stomach through a tube. The drugs dosage is controlled by a mini-pump weighing about half a kilogram that the patient wears at the waist. The body transforms levodopa to dopamine to increase the amount of dopamine in the brain. Parkinsons disease symptoms are linked to dopamine levels. Carbidopa helps to guide levodopa to the brain and also helps to avoid stomach upset and other undesirable side effects of levodopa.
The benefit of the Duodopa treatment is that the patient gets the drug continuously and so avoids the kinds of fluctuations that can come when drugs are taken orally at intervals during the day. Some patients have difficulty swallowing, and with this treatment, theres no need to swallow, says Dr. Anne-Louise Lafontaine, a neurologist and Director at The Neuros Movement Disorder Clinic.
Not all Parkinsons disease patients will qualify for the treatment.

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 .

Why Should I Participate In A Clinical Study
We can only reach breakthroughs in treatment and care if people participate in the studies.
Participating is safe and can help you
Every clinical study is reviewed thoroughly before your doctor asks you to participate. Clinical trials carry some risks, but your doctor is required by law to explain the risks to you clearly and make sure that you understand them. If your doctor tells you about the risks of participating in the study, ask yourself, What are the risks of not participating in the study? Most of the time, if you balance the possible benefits from participating against the risks, it is about the same as the risks of not being in the study.
On the other hand, the study may be of a new drug or treatment that could help you. If you dont participate, it may be years before you have a chance to try that drug.
Some people do not participate because there is no guarantee they will get the experimental therapy they might get the placebo. Again, think carefully about the risks and benefits of entering the study and getting the new treatment, entering the study and getting the placebo or not entering the study at all.
Your participation can help others
If you have PD or any other disease, the drugs, procedures and therapies you use now were scientifically tested, likely by thousands of volunteers. Participating in a clinical trial is your way to pay it forward for people diagnosed with Parkinsons in the future.
Searching To Control Symptoms: New Methods Of Delivery
In recent months, symptomatic treatment of PD has had some new developments as well. A new drug for PD, rotigotine, has been introduced in Europe and elsewhere as Neupro. This compound is a dopaminergic agonist, a class of drugs that also includes drugs that have been available for many years in the U.S., including Mirapex, Requip, and Permax . Neupro is unique in how it is delivered: it is absorbed through the skin and so has been marketed as a transdermal patch with continuous delivery over 24 hours. So far, experience with Neupro suggests that it is effective and well tolerated. However, whether this drug or its unique mode of delivery will offer a significant advantage over currently marketed medications of the same class still remains to be learned.
PD still presents many challenges for the medications of the future. Among the unmet needs are ways to reverse the problem of imbalance, especially falling backward. The flexed posture of PD, swallowing and speech difficulties, and situation-specific “freezing” are all challenges for improved drug therapy. Scientists have not yet determined where in the brain and what types of biochemical disturbance underlie these problems.

Stem Cells For Parkinson’s Disease Are Safe And Effective
According the Venkataraman and colleagues, “A subjective improvement was found in symptoms like facial expression, gait, and freezing episodes 2 patients have significantly reduced the dosages of PD medicine. These results indicate that our protocol seems to be safe, and no serious adverse events occurred after stem-cell transplantation in PD patients.”
As stated in a 2005 study held by Brian Snyder,
Stem cells offer the potential to provide a virtually unlimited supply of optimized dopaminergic neurons that can provide enhanced benefits in comparison to fetal mesencephalic transplants. Stem cells have now been shown to be capable of differentiating into dopamine neurons that provide benefits following transplantation in animal models of Parkinson’s disease.
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.

Parkinsons Disease: Causes Symptoms And Treatments
Parkinsons disease is a brain disorder that causes unintended or uncontrollable movements, such as shaking, stiffness, and difficulty with balance and coordination.
Symptoms usually begin gradually and worsen over time. As the disease progresses, people may have difficulty walking and talking. They may also have mental and behavioral changes, sleep problems, depression, memory difficulties, and fatigue.
While virtually anyone could be at risk for developing Parkinsons, some research studies suggest this disease affects more men than women. Its unclear why, but studies are underway to understand factors that may increase a persons risk. One clear risk is age: Although most people with Parkinsons first develop the disease after age 60, about 5% to 10% experience onset before the age of 50. Early-onset forms of Parkinsons are often, but not always, inherited, and some forms have been linked to specific gene mutations.
Designer Neurons Offer New Hope For Treatment Of Parkinson’s Disease

- Summary:
- Scientists describe a process for converting non-neuronal cells into functioning neurons able to take up residence in the brain, send out their fibrous branches across neural tissue, form synapses, dispense dopamine and restore capacities undermined by Parkinson’s destruction of dopaminergic cells.
Neurodegenerative diseases damage and destroy neurons, ravaging both mental and physical health. Parkinson’s disease, which affects over 10 million people worldwide, is no exception. The most obvious symptoms of Parkinson’s disease arise after the illness damages a specific class of neuron located in the midbrain. The effect is to rob the brain of dopamine — a key neurotransmitter produced by the affected neurons.
In new research, Jeffrey Kordower and his colleagues describe a process for converting non-neuronal cells into functioning neurons able to take up residence in the brain, send out their fibrous branches across neural tissue, form synapses, dispense dopamine and restore capacities undermined by Parkinson’s destruction of dopaminergic cells.
The current proof-of-concept study reveals that one group of experimentally engineered cells performs optimally in terms of survival, growth, neural connectivity, and dopamine production, when implanted in the brains of rats. The study demonstrates that the result of such neural grafts is to effectively reverse motor symptoms due to Parkinson’s disease.

The First Participant Has Been Recruited To A Pioneering Clinical Trial Which Is Testing A New Drug Called Nlx
Parkinsons disease is a condition in which parts of the brain become progressively damaged over many years. The main three symptoms manifest themselves in involuntary shaking of parts of the body, slow movement, and stiff, inflexible muscles.
People with Parkinsons struggle to make enough dopamine. They take medications like levodopa which help their struggling dopamine cells to make more of this chemical and helps improve symptoms, especially difficulty in movement.
However, serotonin cells also get involved in using levodopa to make and release dopamine, but they do so in an erratic manner. This uncontrolled release of dopamine leads to distressing uncontrollable movements called dyskinesia.
The trial is led by researchers at the Karolinska Institute in Stockholm and at 4 other sites in Sweden. A total of 24 participants will be involved, with 16 receiving NLX-112 and the remainder an inactive pill for comparison.

How Could Stem Cells Help People With Parkinson’s
Stem cells are the parent cells of all tissues in the body. This means they can turn into any type of cell. The hope is that they will eventually be able to make these cells into specific types of cells, like dopamine-producing neurons, that can be used to treat Parkinson’s disease. However, there are concerns that patients may have the same risk of increased involuntary movements as those who undergo fetal cell transplantation. And, like fetal cell transplantation, stem cell therapy is surrounded by moral and ethical controversy.
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.

Stem Cell Therapy For Parkinsons Disease
Stem cell therapy may have the benefit of replacing and repairing damaged dopamine-producing nerve cells within the brain. This has already been found in a study conducted by Neelam K.Venkataramana and colleagues. Seven PD patients aged 22 to 62 years with a mean duration of disease 14.7 ± 7.56 years were enrolled to participate in the prospective, uncontrolled, pilot study of single-dose, unilateral transplantation of autologous bone-marrow-derived mesenchymal stem cells . Patients were followed up for 36 months post-transplant, 3 of the 7 patients showed significant improvement in their Unified Parkinsons Disease Rating Scale of 38%.
According to Medical News Today Currently, the most common therapy uses the drug levodopa to stimulate dopamine production in certain neurons associated with motor skills. These dopaminergic neurons are situated in the nigrostriatal pathway which is a brain circuit that connects neurons in the substantia nigra pars compacta with the dorsal striatum. However, levodopa has a wide array of side effects, from physiological to psychological ones. Also, in the long-term, the benefits of such dopamine-regulating drugs are limited. So, scientists must come up with more effective strategies for repairing the brain damage that Parkinsons disease causes.
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 .

New Form Of Drug Helping Some Patients With Parkinsons Disease
For more than 40 years, a drug called levodopa has been the most effective treatment for the uncontrolled movements associated with Parkinsons disease. Many Parkinsons patients have taken a pill form of the medicine also known as L-dopa for years to control their motor fluctuations.
But the pills can lose effectiveness over time, greatly reducing their value for people in the later stages of the disease.
Now theres a new form of the drug that is making a positive difference for some Parkinsons patients. Duopa is a drug thats delivered continuously by a pump system instead of pills.
This takes care of the fluctuations in the movement symptoms that advanced Parkinsons patients experience on a daily basis, and they dont have to rely on pills while the pump is on, said movement disorders specialist Dr. Mustafa Saad Siddiqui, an associate professor of neurology at Wake Forest Baptist. It can mean a very significant improvement in the quality of life of these patients.
Parkinsons disease is a degenerative disorder of the brain cells that produce dopamine, a chemical that helps people control body movements. While tremors are the best-known sign of Parkinsons, it can also cause muscle rigidity and slowing of movement. There is no cure for the disease, which afflicts approximately 1 million people in the United States, including actor Michael J. Fox and boxing legend Muhammad Ali.
Link Could Play Role In Pd Development
To investigate the mechanism of Syn-induced immune responses to viral infections in the brain, the researchers challenged Syn knock-out mice and human Syn KO dopaminergic neurons with RNA virus infection. They discovered that Syn is required for neuronal expression of interferon-stimulated genes . They then found that following any stimulus that triggers interferon signals, a type of immune response, Syn interacts with signaling proteins in neurons to trigger expression of ISGs.
This work provides the first clear mechanism that links inflammation and aSyn, a protein that is closely associated with the development of Parkinsons disease.
The authors mention that this data confirms that Syn responds to infection and inflammatory pathways and suggests that this interaction may play an important role in the development of Parkinsons disease. The next important step is to determine if the interactions between interferon and Syn trigger the formation of the toxic forms of misfolded Syn, called fibrils, that have been found in Parkinsons disease.
The researchers suggest future studies are needed to look into the interactions between type 1 interferon signals in neurons and misfolded Syn to determine if drugs that inhibit these interactions can prevent the formation of misfolded Syn. This would result in a potential disease-modifying therapeutic approach that is needed for patients.
