Intestinal Infusion Pump For Delivery Of Duodopa
Duodopa is a gel form of levodopa and is used to treat severe motor fluctuations with prolonged and disabling off times and troublesome dyskinesia.
A PEG-J tube is inserted into the intestine via a stoma or hole in the stomach wall. A cassette containing the gel is inserted into a pump worn by the person that is programmed to deliver the gel at the required rate.
New Hope For Parkinsons Patients
Developing better patient care and family support for people with Parkinsons Disease and related conditions is the key mission of the Brain and Mind Centres ForeFront Parkinsons Disease Research Clinic.
Were currently running a symptomatic trial for Parkinsons patients who have depression and were also recruiting for patients with Parkinsons Disease, Dementia and Dementia Lewy Bodies, for a trial to try and improve their concentration, said Professor Lewis.
Also on the horizon is a trial that aims to treat Parkinsons patients experiencing freezing of gait episodes a particular research passion for Professor Lewis. His team is also working on another disease slowing trial for treating another rare movement disorder, known as Progressive Supranuclear Palsy.
With all clinical trials, there is a vital balance required for maximum results. Both the need for research funding, combined with the importance of patient involvement are the foundational building blocks for a successful outcome, working towards the successful development of patient care and treatment in the future.
What Are The Symptoms Of Parkinson’s Disease
The main symptoms of Parkinson’s disease are:
- tremor or shaking, often when resting or tired. It usually begins in one arm or hand
- muscle rigidity or stiffness, which can limit movement and may be painful
- slowing of movement, which may lead to periods of freezing and small shuffling steps
- stooped posture and balance problems
The symptoms of Parkinson’s disease vary from person to person as well as over time. Some people also experience:
- loss of unconscious movements, such as blinking and smiling
- difficulties with handwriting
- drop in blood pressure leading to dizziness
- difficulty swallowing
Many of the symptoms of Parkinson’s disease could be caused by other conditions. For example, stooped posture could be caused by osteoporosis. But if you are worried by your symptoms, it is a good idea to see your doctor.

Australia Continues To Forge Ahead
Its not the first time Australian researchers have been involved in potentially groundbreaking treatments for Parkinsons disease.
In November, The New Daily reported that researchers at the University of Queensland partly funded by the Michael J Fox Foundation had developed a world-first pill that could stop the death of brain cells in Parkinsons sufferers rather than just managing symptoms.
Phase one tests of this drug are expected to take place this year, and all going well, phase two will follow in 2020.
Lack Of Dopamine Does Not Cause Parkinson Disease
LACK OF DOPAMINE DOES NOT CAUSE PARKINSON SYMPTOMS AND LESIONS ON AN MRI, OR A DATSCAN TEST, HAVE NOTHINGTO DO WITH THE CAUSE OF THESE SYMPTOMS, AS YOU WILL SEE IN THIS VIDEO!
Doctors and neurologists are still taught, lack of the hormone DOPAMINE due to atrophy , of the dopamine-producing cells in the Substantia Nigra in the brain stem, is the cause of Parkinson symptoms, which is what enables dopamine drugs to legally be prescribed. Even simple common sense tells us, DEATHof dopamine-producing cells in the substantia nigra couldnt possibly be the cause of Parkinson symptoms when Parkinson symptoms often vary dramatically, just from an afternoon sleep, because, for Parkinson symptoms to vary, different amounts of dopamine would need to be manufactured and released, to regulate these variations.
This also means, every time a patients symptoms diminish and then return, dopamine-producing cells in the substantia nigra would have to quickly come back to life and produce dopamine, then die off again, then come back to life, etc, etc,. Common-sense says, this is totally impossible!!!
Muscle Tension Suppresses Nerve Signals.
Watch this video adjacent, & see the progressive deterioration of the cervical spine, which I sometimes see in advanced Parkinson, MS, COPD & Sarcoid patients. Please remember, not all patients of these disorders, have such spinal problems, but they DO all have excess rigidity in the whole muscular system, particularly in the lower back and hips.

How Is Parkinson’s Disease Managed
Your doctors will tailor your treatment based on your individual circumstances. You will manage your condition best if you have the support of a team, which may include a general practitioner, neurologist, physiotherapist, occupational therapist, psychologist, specialist nurse and dietitian.
While there is no cure for Parkinson’s disease, symptoms can be treated with a combination of the following.
Medications For People With Parkinsons Disease
Symptoms of Parkinsons disease result from the progressive degeneration of nerve cells in the brain and other organs such as the gut, which produce a neurotransmitter called dopamine. This causes a deficiency in the availability of dopamine, which is necessary for smooth and controlled movements. Medication therapy focuses on maximising the availability of dopamine in the brain. Medication regimes are individually tailored to your specific need. Parkinsons medications fit into one of the following broad categories:
- levodopa dopamine replacement therapy
- dopamine agonists mimic the action of dopamine
- COMT inhibitors used along with levodopa. This medication blocks an enzyme known as COMT to prevent levodopa breaking down in the intestine, allowing more of it to reach the brain
- anticholinergics block the effect of another brain chemical to rebalance its levels with dopamine
- amantadine has anticholinergic properties and improves dopamine transmission
- MAO type B inhibitors prevent the metabolism of dopamine within the brain.

Parkinsons Disease Symptoms: Life Expectancy
Even though Parkinsons disease is a serious, progressive condition, it is not considered a fatal illness. People who have Parkinsons disease usually have the same average life expectancy as people without the disease.
But when the disease is in its advanced stages, Parkinsons symptoms can lead to life-threatening complications, including:
- Falls that lead to fractured bones
Thinking about the progression of Parkinsons disease can be frightening. But proper treatments can help you live a full, productive life for years to come. And researchers hope to one day find ways to halt the progression of Parkinsons and restore lost functioning.
Sidebar: Ninds Steps Up Pursuit Of Pd Biomarkers
In 2012, the NINDS dramatically accelerated efforts to identify biomarkers by establishing the Parkinsons Disease Biomarkers Program . This unprecedented program unites a range of stakeholders from basic and clinical researchers to healthcare professionals, the NINDS staff, information technology experts, and people living with PD and their families.
PDBP supports research and builds resources aimed at accelerating the discovery of biomarkers to ultimately slow the progression of PD. For example, the program has established a repository of biological specimens and a Data Management Resource system maintained by the NIH Center for Information Technology. The DMR allows researchers to access clinical, imaging, genetic, and biologic data, while a complementary PDBP-supported project develops statistical tools to analyze vast quantities of data so that patterns can be identified across these diverse sources of information.

Physical And Supportive Therapies
People with Parkinsons disease should remain as active as possible, maintaining daily activities and, if possible, a regular exercise program. Support therapies from physiotherapists, occupational and speech therapists can also help with specific exercises, education and retraining to improve coordination, balance and movement. Overall fitness and good muscle tone can help minimise some of the abnormal movements associated with Parkinsons disease.
There Is No Known Cause For The Development Of Parkinsons However It Is Thought That A Combination Of The Following May Play A Role
We understand that the neurones in a particular area of the brain known as the substantia nigra are damaged or lost. This results in a reduction in dopamine, a powerful brain chemical that assists in coordinating movement.
There is no cure for Parkinsons disease, but there are effective treatment and therapy options that can help manage symptoms, so people with Parkinsons disease can continue to enjoy many years of independent and productive lives.
There is still much to learn about what causes Parkinsons disease, but research is ongoing and there is every hope that outcomes for people with Parkinsons disease will continue to improve and that ultimately there will be a cure. In the meantime, community organisations like Parkinsons NSW will continue to offer information, education, counselling, advocacy and support.

Study Design And Setting
This retrospective cohort study utilized Australian Pharmaceutical Benefit Scheme data for a random representative 10% sample of the Australian population . The PBS random sample has been made available to research by Services Australia. The 10% random sample is derived from a one in ten random sample of patients eligible to the Australias universal health care system Medicare, and dispensed medications via the PBS. The PBS subsidizes prescription medications for Australias 25 million citizens, permanent residents and foreign visitors from countries with reciprocal health care agreements. The data contain person-level records of all reimbursed medications dispensed from community pharmacies, private hospitals and public hospital outpatient and discharge dispensing in all states except New South Wales and Australian Capital Territory. Since July 2012, all under co-payment are captured. Data include quantity dispensed, PBS item code, dispensing date, sex, birth year, death year, and concessional status. PBS item codes are mapped to the medication name, strength and Anatomical Therapeutic Chemical Classification codes .

How Is Parkinsons Diagnosed
Doctors use your medical history and physical examination to diagnose Parkinsons disease . No blood test, brain scan or other test can be used to make a definitive diagnosis of PD.
Researchers believe that in most people, Parkinsons is caused by a combination ofenvironmental and geneticfactors. Certain environmental exposures, such as pesticides and head injury, are associated with an increased risk of PD. Still, most people have no clear exposure that doctors can point to as a straightforward cause. The same goes for genetics. Certain genetic mutations are linked to an increased risk of PD. But in the vast majority of people, Parkinsons is not directly related to a single genetic mutation. Learning more about the genetics of Parkinsons is one of our best chances to understand more about the disease and discover how to slow or stop its progression.
Aging is the greatest risk factor for Parkinsons, and the average age at diagnosis is 60. Still, some people get PD at 40 or younger.
Men are diagnosed with Parkinsons at a higher rate than women and whites more than other races. Researchers are studying these disparities to understand more about the disease and health care access and to improve inclusivity across care and research.
Aging is the greatest risk factor for Parkinsons, and the average age at diagnosis is 60. Still, some people get PD at 40 or younger.

Crossing The Blood Brain Barrier
Many molecules are unable to cross the blood brain barrier . Molecules must be small, non-polar and lipophilic to cross over. If compounds do not possess these qualities they must have a specific transporter that can transport them over the BBB. Dopamine cannot diffuse across the BBB because of the catechol group, it is too polar and therefore unable to enter the brain. The catechol group is a dihydroxy benzene ring.
The synthesis of dopamine consists of three stages. The synthesis process starts with an amino acid, called L-Tyrosine. In the second stage Levodopa is formed by adding a phenol group to the benzene ring of L-Tyrosine. The formation of L-dopa from L-tyrosine is catalyzed by the enzyme tyrosine hydroxylase. The third stage is the formation of dopamine by removing the carboxylic acid group from L-dopa, catalysed by the enzyme dopa decarboxylase.
Levodopa is also too polar to cross the blood brain barrier but it happens to be an amino acid so it has a specialized transporter called L-type amino acid transporter or LAT-1 that helps it diffuse through the barrier.
The Dbs System Consists Of Three Components:
- The lead- a thin, insulated wireis inserted through a small opening in the skull and implanted in the brain. The tip of the electrode is positioned within the targeted brain area.
- The extension- is an insulated wire that is passed under the skin of the head, neck, and shoulder, connecting the lead to the neurostimulator.
- The neurostimulator- is the third component and is usually implanted under the skin near the collarbone. In some cases it may be implanted lower in the chest or under the skin over the abdomen.

Australian Researchers Hope Brain Gel Can Reverse Parkinsons Disease Symptoms
Australian researchers say they have developed a new type of gel that could radically transform the treatment of Parkinsons disease and could also help stroke patients.
The hydrogel is made from natural amino acids, the building blocks of proteins, and has been shown to safely deliver replacement cells into damaged parts of the brain.
The gel acts as a vehicle to safely transfer stem cells into the brain. Scientists believe the process can restore damaged tissue and replace lost neurons, which affect patients with Parkinsons disease, a nervous system disorder. About 100,000 Australians are estimated to suffer from the disease, which currently has no cure.
If you imagine a stroke, you have a whole bunch of dead cells where you are no longer getting blood flow, said professor David Nisbet, one of the lead researchers from the Australian National Universitys College of Health and Medicine. In terms of Parkinsons disease, you lost population of neurons, thats what results in the symptoms we are familiar with seeing. Basically, what we are doing we are introducing replacement cells into the brain to replace those ones that we can see some repair and regeneration. But they also have the added advantage that we have also shown they can actually protect some of the existing cells in the surrounding tissue once they are implanted.
Nisbet said the early results are encouraging.
