What Will A Cure For Parkinson’s Look Like
Because Parkinson’s varies so much from person to person, 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.
On Times And Off Times
“ON time” refers to periods when medications are adequately working and the symptoms of Parkinsons disease are controlled.
“OFF time” refers to periods when the medications wear off and Parkinsons symptoms, such as tremor, rigidity, and difficulty walking reappear.
The addition of safinamide to drug regimens of people with advanced Parkinsons disease taking levodopa increases the amount of ON time and decreases OFF time.

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
Anatomy Morphology And Functional Organization Of The Midbrain Da System
The complexity of the dopaminergic system seems to coincide with evolutionary development given that the number, size, and distribution, as well as receptor subtypes of dopaminergic neurons in the brain, increases alongside phylogenetic complexity . For example, dopaminergic terminal fields arising from midbrain clusters are more prominent and less segregated in the neocortex of primates than in rodents .
Dopaminergic neurons in the midbrain are mainly located in the SNc and VTA, although some smaller clusters have been found elsewhere, for instance, the dorsal and median raphe nuclei . In a classic article by Dahlstroem and Fuxe , SNc and VTA DA neurons were characterized based on their organization and projection patterns, which, in rat, can be found discrete clusters . SNc neurons innervate the dorsal and lateral striatum, thus forming a nigrostriatal pathway , and are necessary for the initiation and control of motor movements. Accordingly, the degeneration of this pathway is considered to be responsible for much of the motor dysfunction associated with PD. The VTA innervates the ventral striatum, nucleus accumbens, and limbic and cortical areas, and this way forms the mesolimbic and mesocortical pathways .

What New Treatments Are Being Developed
Thanks to the progress we’ve already made, new treatments are being tested in clinical trials that have the potential to slow, stop or even reverse Parkinson’s.
These include:
- stem cell therapies, which aim to use healthy, living cells to replace or repair the damage in the brains of people with Parkinson’s
- gene therapies, which use the power of genetics to reprogramme cells and change their behaviour to help them stay healthy and work better for longer
- growth factors , which are naturally occurring molecules that support the growth, development and survival of brain cells.
And we’re developing treatments that aim to improve life with the condition, including new drugs that can reduce dyskinesia.
Garment Technologies To Prevent Falls
Frequent falls, owing to faulty gait and posture are common among people with Parkinson’s Disease. A team of researchers are in the process of developing smart garment technologies that would prevent falls in people with this neurological condition. The researchers from Neuroscience Research Australia and University of New South Wales are set to make StandingTall-PD, a neuro-rehabilitation programme that aims to prevent freezing-of-gait and falls, and enhance patients independence. The programme uses visual, audio and haptic sensory cues to help rewire the parts of the brain that control walking and prevent falls. The combination of visual, audio and sensory elements helps to form new connections in the less affected parts of the brain, leading to improved walking ability, the researchers said.
Existing dopamine therapies offer benefit in treating motor dysfunction in Parkinson s but may not alleviate gait and balance challenges, said Jamie L. Hamilton, Associate Director at the Michael J. Fox Foundation in the US.
The new programme has the potential to become an affordable option to address gait and balance issues and improve overall quality of life for people with Parkinson s, added Hamilton.
For the study, researchers will give participants a mat with colour-coded stepping targets, a pair of Sensoria Smart Socks, an iPad and phone.

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 we 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.

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.

Naturaltreatment For Parkinsons #6 Magnesium & Iodine:
Magnesium is vital for the health of the entire nervoussystem, especially the protective layer that surrounds the nerves . Magnesiumis also essential for the production of dopamine and helps protect dopaminergicneurons in the substantia nigra from degeneration. In addition to this, new evidence is showing that low levels of magnesium in the brain causes a build-up ofheavy metals a major factor in the development of Parkinsons, Alzheimers,epilepsy and MS. In a recent trial, 30 epileptics were given 450 mg ofmagnesium daily and this successfully controlled their seizures. Ifmagnesium can help epilepsy patients, it can certainly help Parkinsons sufferers. Worldrenowned magnesium expert and author, Dr Carolyn Dean, has both Parkinsons andAlzheimers disease in her top 55 health conditions caused by amagnesium deficiency list and says that magnesium is 100% essential for the preventionand treatment of both of these diseases Dr Carolyn Dean Interview
In regards to iodine, well-known researcher and author,Dr James Howenstein, says
Iodineis found in large quantities in the brain and the ciliary body of the eye. A lackof iodine may be involved in the production of Parkinson’s disease andglaucoma.
Inthe brain, iodine concentrates in the substantia nigra, an area of the brainthat has been associated with Parkinson’s disease.

FDA Approves Investigational NDA for Ketamine in Levodopa-Induced Dykinesia
As the gold standard of treatment for PD, levodopa effectively reduces parkinsonian symptoms, although long-term use has been linked with several adverse events. Chief among these, frequency of OFF time and abnormal involuntary movements, known as levodopa-induced dyskinesia , have been shown to significantly impact quality of life and treatment efficacy.
There are no approved treatments to address LID however, an article by NeurologyLive® indicates there may be some progress in addressing this issue. Last week, the FDA approved PharmaTher Holdings investigational new drug application for ketamine, an N-methyl-D-aspartate receptor-modulating drug, in the treatment of LID in patients with PD.
A phase 2 clinical trial evaluating the safety, efficacy, and pharmacokinetics of ketamine compared with the active control treatment of midazolam is expected to begin patient enrollment in the third quarter of this year. Pending success, the manufacturer noted that it will seek an agreement with the FDA to proceed to a phase 3 clinical study next year.

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 .

Latest Treatments For Parkinsons Disease
Researchers still have much to learn about Parkinsons disease. As researchers continue to work hard in the fight against this disease, the lessons they learn may lead to new, innovative treatments.
Parkinsons disease is a neurodegenerative disorder that affects dopaminergic neurons in the substantia nigra area of the brain, advises the Parkinsons Foundation. Even though the disease itself is not fatal, PD is a serious condition one which the Centers for Disease Control and Prevention rates as the 14th most common cause of death in the United States due to the diseases related complications.
PD symptoms affect autonomous functions and the ability to move limbs. The Mayo Clinic notes that most people with PD may show little or no expression, speech may become slurred, arms may not swing when one walks, and stiffness and gait issues may become apparent. PD can affect balance and posture as well.
There is no cure for PD, but there are many different treatments that can slow its progress and reduce symptoms.
WebMD says new treatments for PD give individuals continued hope. Heres a look at some of the potential options.
Stem cell usagetem cells can turn into any type of cell, and there is hope that they can transform into the dopamine-producing neurons used to treat PD. But there is increased risk of involuntary movement from too much dopamine with this treatment. Stem cell therapy also may present ethical and moral issues with some patients.

Age At Disease Onset Results In Distinct Speech Patterns
Results from a Phase 2 trial , reported this year, showed that nilotinib approved to treat certain types of leukemia was safe and led to a dose-dependent increase in dopamine, the chemical messenger essential for muscle control that is lost in Parkinsons. Its use also slowed both motor and non-motor decline in patients treated long term with nilotinib at 300 miligrams , this studys highest dose.
Nilotinib, available under the brand name Tasigna for leukemia patients, works by blocking the activity of a protein called BCR-ABL that is known to support cancer development. However, this protein is also linked to several mechanisms in the brain, such as oxidative stress and alpha-synuclein-induced neurodegeneration, which play critical roles in Parkinsons disease.
To understand the potential mechanisms underlying benefits found in the Phase 2 study, researchers at Georgetown University Medical Center which sponsored that trial analyzed the cerebrospinal fluid of 75 study participants with moderately severe Parkinsons.
Patients had been randomly assigned to one of two oral daily doses of nilotinib 150 mg and 300 mg or to a placebo for one year. Samples from the CSF were collected after one year of treatment.
Following a three-month washout period, 63 patients were once again randomly assigned to the same treatment regimen nilotinib 150 mg or 300 mg or a placebo for an additional year in an open-label study extension. In total, the trial ran for 27 months.

Causes Of Parkinson’s Disease
The causes of Parkinsons disease are still greatly unknown. Scientists who have studied this disorder estimate that 10-15% of cases come from genetics after seeing a series of genetic mutations that were common in Parkinsons patients.
Doctors suspect that environmental factors and lifestyle choices may have effects on the severity of Parkinsons disease symptoms. Exposure to chemicals like pesticides may increase the likelihood of developing Parkinsons disease. On the other hand, a good diet and regular exercise may decrease your chances.

Why Scientists Believe Theyve Made New Breakthrough In Parkinsons Disease Treatment By Building On Gdnf Research
The Finnish researchers are now working to improve the properties of BT13 to make it more effective as a potential treatment that could benefit many people living with the disease.
The study, which was published online yesterday in the journal Movement Disorders, builds on previous research on another molecule that targets the same receptors in the brain.
GDNF or glial cell line-derived neurotrophic factor is an experimental treatment for Parkinsons discovered in 1993 that has been shown to bring dying brain cells back to life and particularly effective in dopamine neurons.
It was the subject of a BBC documentary in February 2019 that followed a phase two trial in Bristol involving 42 patients. While the results werent clear cut, GDNF has shown promise to restore damaged cells in people with Parkinsons.
However, the GDNF protein requires complex robot-assisted surgery to deliver the treatment to the brain because its a large molecule that cant cross the blood-brain barrier a protective wall that prevents some drugs from getting into the brain.
BT13 is a smaller molecule that is able to cross the blood-brain barrier and therefore could be more easily administered as a treatment if shown to be beneficial in further clinical trials.
Dr Yulia Sidorova, lead researcher on the study, said: We are constantly working on improving the effectiveness of BT13.
Our ultimate goal is to progress these compounds to clinical trials in a few coming years.
