Parkinson’s Disease Foundation to Increase Investment in Research, Health Care and Patient Leaders


Research, Health Care and Patient Leaders
How can we put ourselves out of business? Finding the cure for Parkinson’s disease (PD) has been the goal of the Parkinson’s Disease Foundation (PDF) since 1957. But Parkinson’s is still around. And so are we.

The investments of PDF over the past six decades have done much to advance our understanding of PD. They have improved the lives of millions of people worldwide. But we still don’t have the cure. Nothing that can stop the disease. Nothing that can slow it. That is simply unacceptable. There are seven to 10 million people worldwide living with PD who count on us to move the science and the care forward. We owe it to them to make this happen.
In 2014, under the guidance of our Board of Directors, Scientific Advisory Board and People with Parkinson’s Advisory Council, PDF began a year-long examination of how far we have come, and how we can contribute to solving the puzzle moving forward.
The truth is that no one knows when and from where the cure will come. The reality is that many people hold a piece of the puzzle but lack the tools to realize their contribution. PDF’s strategy is to build a team of people — the best and brightest leaders in science, health care, and the patient community who can move the dial in PD research and care — and then mobilize them to work toward the cure together.
After all, if each member has a piece of the PD puzzle, imagine what can happen when we put them together. Here, we report on our plan.

Investing in Research Leaders

The first urgent question PDF asked was: how can we invest in the innovative ideas of young scientists, while ensuring they have the tools needed to transition into our future leaders?
In years past, a talented young investigator — in his or her late 20s or early 30s — was almost assured federal funding to advance innovative ideas and establish a career. But today most scientists have to wait until their mid-40s for funding.
In the meantime, the field’s future leaders are standing on a precipice facing a “valley of death” between their scientific potential and the funding they need to make it happen. We are losing them from the PD fight before they have a chance to contribute.
PDF’s track record of funding early-career scientists is unparalleled — our funding has nurtured leaders driving today’s new therapies — but it is no longer enough. We need to fund the ideas of young innovators and keep the pipeline of scientists full. And we are doing that by focusing $2 million of our total $4.6 million investment in research on early-career scientists.
As part of PDF’s plan to build research leaders, first we recruit scientists early with ‘small but mighty’ fellowships. These low-cost, high-reward programs motivate students to dedicate their careers to PD, while advancing the research of senior scientists.
Once they graduate, we will help to kickstart their innovative ideas. We will step in with an extensive offering of fellowship opportunities — both our own and other opportunities offered with partners like the American Academy of Neurology and the Howard Hughes Medical Institute — that allow scientists to cultivate creativity and take initial steps to prove the potential of their scientific ideas.
Lastly, we’ll help them cross that “valley of death.” As scientists face pressures that may force them to switch careers and leave their research projects incomplete, PDF will be the bridge to ensure no promising idea is left unstudied. We will invest, through mechanisms like the Stanley Fahn Transition Award (named for PDF’s Scientific Director of 40 years), to keep them in the field and help them potentially find a cure for PD.

Investing in Health Care Leaders

We know from our experience that when people with PD work with a health care team — movement disorder specialists, nurses, and physical, occupational and speech therapists — their lives improve.
PDF has a track record of preparing experts to treat PD on the frontlines. We are the largest private funder of training for early-career neurologists to specialize in Parkinson’s, with more than 150 doctors trained to date.
But all too often, professionals on the frontlines are left without sufficient resources or training in PD. For example, nursing students receive less than one hour of instruction on PD during four years of education! Once in the field, many are left to learn about PD themselves, with few opportunities for continuing education.
We must do more. We will start by investing $600,000 a year in growing and empowering health care leaders of today and tomorrow. PDF is preparing future nurses and health care professionals by reaching those with the greatest impact — their teachers — through initiatives such as our flagship Edmond J. Safra Foundation Visiting Nurse Faculty Program at PDF, which has trained nearly 150 faculty members at nursing schools nationwide. These leaders are, in turn, sharing their knowledge with 9,000 students each year and are influencing national standards for nursing education.
Learning from this success, we are implementing a similar model for the field of physical therapy. We expect that within three years, we will have trained 40 faculty leaders, who will in turn train over 1,800 students.
Second, we are supporting professionals on the frontlines, by arming professionals in the nursing, physical therapy and occupational therapy fields — both in conventional classrooms and online — with the tools they need to stay informed and support their patients. Our offerings include free continuing education opportunities and patient education materials.

Investing in Patient Leaders

As those with the most at stake, people with Parkinson’s disease can help the rest of us get our priorities straight. We have seen this prove true in other health communities, when engaged patient advocates have helped to accelerate new treatments.
This is why PDF has advocated relentlessly to make patient engagement a reality. For us, this means engaging people with PD as partners in every part of our work. While we have seen progress, there is much more to be done to ensure that people with PD are recognized and tapped for their insights and potential to help speed research.
This is why PDF is investing $500,000 a year to expand our work to mobilize the grassroots community.
We will continue to build our groundbreaking Parkinson’s Advocates in Research program, which has provided training to more than 260 Research Advocates, who are now working with 400 research professionals on the frontlines to bring better treatments at a faster pace. And we will take the program even further by proactively seeking and guiding advocate-researcher collaborations at universities, pharmaceutical companies and government agencies.
We are also mobilizing new patient leaders to meet specific unmet needs in the community through programs such as the Women and PD Initiative, which launches this fall with a class of 30 women leaders living with Parkinson’s. Each will return to her community with the tools needed to advocate for other women with PD.

Working Together Towards the Cure

PDF’s investments in leadership lay a foundation for improving science, health care and patient engagement. But our ultimate goal is ending Parkinson’s disease. What comes next?
PDF is not only developing leaders; we are also mobilizing them to work toward the cure — together. After all, science and care are team efforts. To that end, PDF has invested close to $50 million in collaborations since 1957, largely toward teams at PD research centers. Today we are taking the strategy further by expanding the opportunities for research, health care and patient leaders to work together.
For example, at Columbia University Medical Center, where we have long funded collaborative teams within the field of PD, we are currently funding teamwork between PD specialists and bioengineers, who are experimenting with ways to design shoe insoles to ease freezing of gait. And at our research center at Rush University Medical Center, we are funding an interdisciplinary project that may one day help doctors to predict who will get PD as part of routine colonoscopies.
We are also expanding funding for research teams that incorporate insights from people with Parkinson’s through our PAIR Leadership Awards and our Community Choice Research Awards. For the latter, we invite the patient community to identify research priorities and then we engage teams of researchers, health professionals, patients and outside experts (e.g., gastroenterologists and psychiatrists) who can help to address them.
No account of PDF efforts in fostering collaborations would be complete without reference to our work sharing PD science with the entire team. We do this online, in print and most recently, through a new partnership with Nature Publishing Group, the world’s leading publisher of scientific journals. The new journal, npj Parkinson’s Disease, is freely available to all with the click of a button.

Conclusions

PDF’s goal is to put itself out of business by ending PD. Until the day comes when we close our doors, please know that they are open to you. Take advantage of our free educational materials, webinars and toll-free HelpLine to find answers, support and resources to help you take charge of PD. Join our team. Get involved as a patient advocate, apply for research funding or take our professional courses. Know that each day, our promise to you is to do everything in our power to accelerate new treatments and end Parkinson’s disease.
And when the day comes to close our doors forever, we can all remember that PDF will not have done it alone: we will have done it as a team.

UVa researchers testing focused ultrasound to treat Parkinson's symptoms

Posted: Saturday, September 19, 2015 1:00 pm


The University of Virginia is leading the first effort to use noninvasive focused ultrasound to treat symptoms of Parkinson’s disease.

Since 2011, UVa has been a center for research in focused ultrasound, the use of high-intensity sound energy to destroy damaged or diseased tissue. It has proved safe and effective for patients with essential tremor, officials said, providing an alternative to risky brain surgery.
-Now researchers say they’re confident it could help treat a range of symptoms in Parkinson’s patients sometimes known as dyskinesia, including tremors and involuntary movements.

“Everybody wants a cure for Parkinson’s, but for the time being, this could be a big breakthrough in symptom management,” said Dr. W. Jeffrey Elias, who has headed several major studies in focused ultrasound.
UVa is collaborating with the University of Maryland — along with centers in Canada and South Korea — to test the effectiveness of the treatment on dozens of patients. Earlier this summer, UVa conducted the first focused ultrasound session on a Parkinson’s patient in the U.S.
Researchers at the University of Maryland conducted another trial one week later, said Dr. Howard M. Eisenberg, chair of the university’s department of neurosurgery.

Patients in the trials will go through several sessions between now and next year, Elias said. Typically, the patients are subjected to focused ultrasound beams for about 10 to 15 seconds at a time. The treatment is essentially painless, though patients have reported discomfort during long sessions.
The point is to interrupt an “abnormal circuit” that forms in Parkinson’s patients, Elias said. Doctors do this by directing more than 1,000 beams of sound deep inside the skull to a part of the brain smaller than a grain of rice.
 “We’re able to do the type of treatment that would usually require making a hole in the head and inserting a probe,” Elias said. “We’re able to do this without making an incision in the head.”

Interrupting these abnormal circuits can relieve rigidity and tremors in patients, Eisenberg said.
“When you have Parkinson’s, some cells in the brain degenerate — that is one of the major pathologies,” he said. “If you perturb the system, you can relieve some of those symptoms.”
The focused ultrasound procedure produces nearly the same results as the invasive brain surgery used on patients until the late 1960s. After that era, doctors began using the drug levodopa — L-dopa for short — to treat symptoms. L-dopa has allowed doctors to treat symptoms without surgery since then, but patients often reach a “ceiling,” Elias said. The longer they take it, the less effective it becomes.

When the drug has become completely ineffective, doctors sometimes resort to deep brain stimulation, a risky surgical procedure that involves implanting electrodes into the brain. When the batteries powering the device run out, patients could need another procedure.

“Over the years, it became clear patients needed more L-dopa as time went on and there were side effects,” Eisenberg said. “The possible place of focused ultrasound is to be another step. … This could replace [deep brain stimulation].”
Like anything else, the ultrasound treatment carries risks, Elias said, including “neurological events” such as a stroke or a hemorrhage. But researchers believe the risk should be significantly lower than the risk associated with deep brain stimulation, he said.

“We’re in the process of figuring out what is the perfect amount of treatment to balance the risk of side effects with the durability of the treatment,” Elias said.
The study, funded by a partnership between the Focused Ultrasound Foundation and The Michael J. Fox Foundation for Parkinson’s Research, is still searching for volunteers. Patients whose medication has failed to satisfactorily control dyskinesia are eligible.


Anyone interested in the trials can contact the Focused Ultrasound Foundation at (434) 220-4993.

Technology used to tag prisoners is now helping doctors measure sleep spasms of Parkinson's sufferers


The buddi bracelet has identified a previously unknown symptom, that sufferers experience spasms in their sleep

  • Devices to help better understand disease and lead to improved treatments
  • Tracker has recorded sleep spasms doctors were previously unaware of 
  • Spasms do not wake sufferer and therefore were unreported to medics
  • Only clue for medics was patients feeling unwell the next day 
  •  
The breakthrough was made by the technology firm, which is owned by businesswoman Sara Murray, and provides monitoring alarm bracelets for the NHS, local authorities and Ministry of Defence. 
'It is very early days but we will be presenting our data to the medical establishment because it seems quite clear that this discovery has great potential for doctors to learn more about this awful disease,' said Buddi's chief executive Ms Murray, the founder of Confused.com and a member of the Government's Technology Strategy Board.
'It may even form the basis of new forms of treatments depending on the findings of doctors.'
The data was recorded on the wristbands as sufferers slept. 
The Buddi system works as 24/7 monitoring and personal emergency response service. It not only tracks the user's whereabouts using GPS, but alerts their next of kin or carers if the person appears to be in trouble.
It comes in three parts, the wristband, a clip which is attached to a lanyard or key ring and the dock.
The buddi was created by entrepreneur Sara Murray
The buddi was created by entrepreneur Sara Murray
The wristband goes everywhere with the user and traces movements and can raise the alarm if it detects a fall.
Unlike many personal alarm systems which are taken off at night, the Buddi wristband is designed to be worn during sleep incase of falls on the way to the bathroom and this is how the spasms were detected.
Falls are detected automatically and the device immediately sends an alarm call but the wristband also monitors activity levels during sleep and can detect restless sleep.
The graphs from these movement logs on 3,000 wristbands were analysed by Buddi which lead to the discovery of the sleeping spasms.
The Parkinson's findings became clear with the analysis of six months of data per individual.
Ms Murray added: 'The data from the Buddi is unequivocal in that is shows Parkinson's sufferers are experiencing previously undiscovered spasms in their sleep.
'Often they report to their doctor feeling very unwell the next day and doctors have not been able to explain this.
'At the very least our discovery will help patients manage their medication better because one possible cause of the spasms could be because the patient is not taking tablets at the right time.
'However, that is only part of the story. The fact that these spasms are happening gives a whole new area of investigation for the medical profession.
'We will do everything we can to help and make all our data available.'
Parkinson's afflicts about 127,000 people in the UK and there is no cure though there are a range of treatments to manage the condition.
It is a progressive neurological illness which usually affects people over the age of 50 and the three main symptoms are tremors, muscle stiffness and slowness of movement.
The condition is triggered because there is a shortage of chemical called dopamine because specific nerve cells in the brain have died.
No-one is immune from the disease which has struck down the former heavyweight boxer Muhammad Ali, Hollywood star Michael J Fox, the late country singer Johnny Cash and the evangelist Billy Graham.
Closer to home the Scottish comedian and actor Billy Connolly has been diagnosed as a sufferer. Roger Bannister, the first man to run a four-minute mile was among its sufferers as well as Ray Kennedy the former Arsenal, Liverpool and England footballer.
Buddi operates an emergency monitoring centre in the UK which is manned 24/7 365 days a year to react to emergencies.
The firm works with over 100 local authorities and NHS Trusts to help protect vulnerable people.
Murray, who has forged a reputation as one of Britain's top innovators and was named entrepreneur of the year in 2009, was in the headlines last year when one of her tracking devices helped convict criminal Darren Girling, 38, who tried to dodge a speeding ticket while on bail.
His tracking device, worn as part of his bail conditions, was using GPS technology and put him at the scene of the crime.
Girling was caught riding a scooter at 41mph in a 30mph zone on the A13 in Leigh, Essex. He claimed someone else had 'cloned' his bike and it wasn't him on the scooter.
But the Buddi tracker - dubbed 'ChavNav' - proved he was lying.
Murray created Buddi in 2005 after the horror she felt when her young daughter temporarily disappeared in a supermarket.

LONG TERM EFFECTS OF DBS ON PARKINSON'S DISEASE

Researchers assessed the long term effect of Subthalamic nucleus Deep Brain Stimulation (DBS) on Parkinson's Disease. People with Parkinson's Disease were assessed before DBS and 1, 3, 5 years after DBS had begun.
DBS involves the use of electrodes that are implanted into the brain and connected to a small electrical device called a pulse generator that can be externally programmed. DBS can reduce the need for L-dopa and related drugs, and reduce dyskinesia. For more information go to : http://www.ninds.nih.gov/disorders/deep_brain_stimulation/deep_brain_stimulation.htm 


As a result of DBS the quality of life improved by 58% after 3 years but gradually declined afterwards. Sleep, cognition, and emotion were mostly unchanged. After 5 years, when assessed without medication DBS improved Parkinson's Disease motor symptoms by 35%. However, after 5 years, when assessed with the simultaneous use of medication, motor symptoms were similar to those at the outset. L-dopa intake was reduced from 660mg to 310mg after 5 years. STN DBS can therefore improve Parkinson's Disease and reduce the need for L-dopa but there is a gradual decline and diminished efficacy after five years of use.

Everyday activity more beneficial than occasional strenuous exercise for Parkinson's disease

PR Newswire
ANN ARBOR, Mich.Sept. 17, 2015 /PRNewswire-USNewswire/ -- New University of Michigan research finds people with Parkinson's disease may want to consider attempting to do the dishes, fold the laundry and take strolls around the neighborhood in their quest to control their symptoms.
Parkinson's patients often become sedentary because of motor symptoms such as gait, balance problems or falls, said study principal investigator Nicolaas Bohnen, M.D., Ph.D., director of the U-M Functional Neuroimaging, Cognitive and Mobility Laboratory.
Once patients feel unstable on their feet, they may develop a fear of falling and then get scared to do any activity at all. Bohnen's team investigated whether participation in exercise, like swimming or aerobics, could help alleviate the motor symptoms that made these patients want to stay sedentary in the first place.
"What we found was it's not so much the exercise, but the routine activities from daily living that were protecting motor skills," Bohnen said. "Sitting is bad for anybody, but it's even worse for Parkinson's patients."
The imaging study, now available online in Parkinsonism and Related Disorders, was conducted by U-M faculty who hold appointments in both radiology and neurology.  
Researchers investigated the relationship between the duration of both non-exercise and exercise physical activity and motor symptom severity for 48 Parkinson's disease patients over a 4-week period. They performed PET brain imaging to measure dopamine levels and used a questionnaire to learn about how physically active the patients were, including both exercise and non-exercise activity. They found that non-exercise physical activity was linked to less severe motor symptoms. 
Although loss of dopamine is a key brain change for Parkinson's patients, and has been thought to be the main reason why Parkinson's patients become more sedentary, the researchers found non-exercise physical activity protected motor skills even among patients with differing levels of dopamine.
"This may have a big impact for Parkinson's patients," said co-author Jonathan Snider, M.D., clinical lecturer of neurology at the University of Michigan. "Not only worsening Parkinsonism but also increasingly sedentary behavior may explain more severe motor symptoms in advanced Parkinson's disease."
"I tell my patients to stand up, sit less, and move more," said Bohnen, also professor of radiology and neurology at the University of Michigan, VA Ann Arbor Healthcare System staff physician and investigator in U-M's Udall Center for Excellence in Parkinson's Disease Research.

Czech scientists invent system to diagnose Parkinson's disease


ÄŒTK |  
17 SEPTEMBER 2015
Brno, Sept 16 (CTK) - Czech researchers from the laboratory of brain diseases analysis of the University of Technology in Brno have developed a computer system to diagnose Parkinson's disease with more than 90-percent certainty, laboratory head Jiri Mekyska told reporters yesterday.
The system is also able to detect the phase of the disease from the very beginning to its severe form on the basis of the analysis of the patients' writing and speech.
The researchers have tested the system for six years on about 100 patients with Parkinson's disease, in cooperation with the St Anne Teaching Hospital in Brno.
Now all doctors who are interested in it can start using the system.
The system is monitoring how the patient is speaking, writing and drawing, in particular the articulation, as well as quickness, strength and possible shaking.
It provides results in figures on the basis of which doctors can determine whether the patient is healthy or suffers from Parkinson's disease and possibly its phase.
The new invention will save time and money, Mekyska said.
"Above all the possibility to estimate the stage of Parkinson's disease is very important now. Though the disease is incurable, doctors have various methods to attenuate its symptoms and slow down its course," Mekyska said.
On top of that, the six-year research has revealed how to improve the patients' speech.
The patients suffering from Parkinson's disease can be treated by repetitive transcranial magnetic stimulation, which uses magnetic pulses instead of electricity to activate parts of the brain.
The latest research has proved on which part of the brain the method should focus to minimise speech problems, Mekyska added.
Parkinson's disease (PD) is a degenerative disorder of the central nervous system mainly affecting the motor system. The most obvious symptoms include shaking, rigidity, slowness of movement and difficulty with walking and gait.

Rapamycin prevents Parkinson's in mouse model of incurable neurodegenerative disease

Image credit: Shankar Chinta, Ph.D., staff scientist, Buck Institute
Published: 
Rapamycin, an FDA-approved drug that extends lifespan in several species, prevented Parkinson's disease (PD) in middle-age mice that were genetically fated to develop the incurable neurodegenerative motor disease that affects as many as one million Americans. While the rapamycin did great things for the mice, scientists in the Andersen lab at the Buck Institute also got an unexpected plus from the research - a new understanding of the role parkin plays in cellular dynamics, one that challenges the current dogma in PD research and presents new opportunities for drug discovery. The study is currently online in the Journal of Neuroscience.
"Given its side effects as an immunosuppressant, there are issues with long-term use of rapamycin, but the results of our study suggest that use of derivatives of rapamycin or other agents with similar biological properties may constitute novel therapeutics for the disorder," said senior scientist and Buck faculty Julie Andersen, PhD. "Our discoveries regarding parkin may provide an even more important therapeutic target for PD."
Parkin is a protein encoded by the PARK2 gene in humans. Mutations in PARK2 are most commonly linked to both sporadic and familial forms of PD; they diminish the cell's ability to recycle its internal garbage. PD is characterized by the accumulation of damaged proteins and mitochondria in the area of the brain where the neurotransmitter dopamine is produced.
Rapamycin prevented PD symptoms from occurring in middle-aged mice who had a human mutation in the PARK2 gene. Researchers in the Andersen lab expected this benefit to come via the accepted role of parkin - they thought rapamycin would boost the mutated protein's ability to label certain types of cellular garbage for recycling. Instead they discovered that parkin plays a much broader role in the actual recycling of garbage and the manufacturing of new mitochondria.
"This is a completely new, unrecognized, function for parkin," said Andersen. "Our work shows that parkin plays a much broader role than was originally thought in getting rid of damaged mitochondria and proteins. It's very exciting because it gives us new ways to look at potential therapeutics to boost cellular clean up."
Working in both neuronal stem cell models and mouse tissue, scientists found that rapamycin not only boosted the mutated protein's ability to label cellular garbage, but also affected the process of recycling the garbage itself via up-regulation of a protein known as TFEB which increased the degradation and purging of both damaged proteins and mitochondria via a process known as lysosomal autophagy. Apart from rapamycin's effects, Andersen's team also discovered that parkin is involved in mitochondrial biogenesis - via up-regulation of PGC1alpha, a protein which drives increased mitochondrial synthesis.
"Problems with autophagy, which result in the accumulation of damaged proteins and organelles, have long been linked to PD," said Ana Maria Cuervo, MD, PhD, professor and recipient of the Robert and Renée Belfer Chair for the Study of Neurodegenerative Diseases at Albert Einstein College of Medicine in New York City. "This novel role of parkin in the regulation of the overall process of autophagy gives us new ways to address its dysfunction in PD."
"Researchers are already very interested in parkin as it relates to PD," said Andersen. "I'm hoping that uncovering this novel role for the protein will bring it center stage as an extremely important therapeutic target for the disorder."

Top 10 Tips for Exercising with Parkinson’s Disease



  1. Exercise is medicine, so don’t miss a dose.Exercise has been proven to build a healthier heart, lungs, and muscles, boost metabolism, prevent diabetes, and reduces disability. Research shows that exercise can slow many aspects of the physical decline of PD and new research also suggests that exercise may even be neuroprotective – that is, slowing the progression of PD in the brain.
    1. “…Exercise or other motor enrichment methods might delay the onset of parkinsonian symptoms or slow the degenerative process, but only when there are no substantial breaks in motor activity” (1763). – Motor Enrichment and the Induction of Plasticity Before or After Brain Injury (Kleim et al, 2004)
    2. “Our findings indicate that exercise reduces the behavioral impairments elicited by the dopaminergic neurotoxins as well as the loss of DA neurons” – Triggering endogenous neuroprotective processes through exercise in models of dopamine deficiency (Zigmond et al, 2009)
    3. “What is clear is that exercise can influence the multiple levels of support necessary for maintaining optimal neuronal function, which is unique among proposed interventions for aging.” (Anderson et al, 2010)
  2. Be realistic – something is better than nothing.There is no perfect one-size-fits-all exercise for people with Parkinson’s. Don’t wait. Start walking around the block. Or dancing. Find a physical therapist that can design an exercise program that is right for you.
    1. “Considered together. These studies suggest that the type of activity may not be important, but rather that the performance of some sort of physical activity or exercise as opposed to being sedentary is critical.” (Dibble et al, 2008)
    2. It is important to find a physical therapist with expertise in Parkinson’s disease. Ask for a referral or consult a resource like http://www.neuropt.org for a physical therapist who specializes in neurological disorders – or who is board certified as a clinical specialist in neurologic physical therapy – or who typically works with people with PD in their day to day practice. (Ellis, 2010)
  3. Have fun.Consistency is critical and if you don’t enjoy it, you won’t stick with it. Do something you like. Dance, yoga, tai chi, cycling and strength exercises have been shown to help with physical and cognitive symptoms of PD. And because Parkinson’s also robs you of energy, try exercising with a group. Research shows that people stick with exercise when there is encouragement and an expectation for you to show up.
    1. People with Parkinson’s disease who participated in 20 lessons of Tango experienced significant improvements in mobility, social support and health related quality of life – Health-related quality of life and alternative forms of exercise in Parkinson disease (Hackney & Earhart, 2009)
    2. “Maintaining a regular schedule of dancing into old age can preserve cognitive, motor and perceptual abilities and prevent them from degradation…beyond its ability to facilitate balance and posture, dance is a prime candidate for the preservation of everyday life competence of elderly individuals” (Kattenstroth et al, 2010)
  4. Break a sweat:Movement only becomes exercise when it is done several times per week at an intensity that is high enough to be physically challenging. If you can carry a conversation with someone while exercising, you are not working hard enough. Because Parkinson’s is a disease of slowed movement, exercising at a slow rate may not provide the best results. Research shows that it’s not the exercise, but the level of the intensity of the exercise, that may be the most beneficial.
    1. Following forced, intense exercise, Parkinson’s symptoms improved 35%, whereas persons with Parkinson’s completing voluntary exercise did not exhibit any improvement. Despite only completing lower extremity exercise, the forced exercise group demonstrated improvements in upper extremity coordination as well as improvements in stiffness and speed of movement. These results were maintained 4 weeks after the forced exercise stopped. The control and coordination of grasping forces during the performance of a functional bimanual dexterity task improved significantly for patients in the FE group, whereas no changes in motor performance were observed following VE. Improvements in clinical measures of rigidity and bradykinesia and biomechanical measures of bimanual dexterity were maintained 4 weeks after FE cessation. – Forced, Not Voluntary, Exercise Improves Motor Function in PD Patients (Ridgel et al, 2009)
  5. Do three major types of exercise.Do aerobic conditioning or cardiovascular exercise for 30 minutes, three times per week; strength or resistance training for 30 minutes, three times per week and stretching or flexibility exercises daily.
    1. An exercise program consisting of cardiovascular activities, stretching, strengthening, walking and balance training resulted in significant improvements in daily function and quality of life related to mobility. – Efficacy of a Physical Therapy Program in Patients with Parkinson’s Disease: A Randomized Controlled Trial (Ellis et al, 2005).
  6. Start today, don’t wait.The sooner after diagnosis you begin exercising, the greater your physical reserve and self-motivation are likely to be. Don’t wait for the disease to progress further or for problems to emerge. Start strong to stay stronger longer.
    1. “…It is so encouraging to learn based on the observations of this study that exercise training can effectively reverse certain behavioral deficits, like impaired movement, imbalance and inconsistent gait pattern that are associated with the Parkinsonian syndrome in spite of the existing severe loss.” – Restorative effect of endurance exercise on behavioral deficits in the chronic mouse model of Parkinson’s disease with severe neurodegeneration (Pathakos, Kurz & Lau, 2009)
  7. Find an exercise buddy.Exercise with people at a life station and physical ability similar to your own. Especially for people with young-onset Parkinson’s, exercising with peers may be more enjoyable, more motivating and more appropriate than finding a Parkinson’s-specific exercise group.
    1. “Consider developing an exercise buddy system which matches up [individuals] who are already exercising with patients who are just starting out. Such group support from patients with similar medical problems may help improve short-term adherence.” – Clinical Exercise Physiology (Ehrman, Gordon, Visich & Keteyian, 2009)
    2. “In our experience implementing community exercise programs for people with PD, it is often easier for those with apathy or depression to ‘show up’ at an appointment to exercise compared to exercising independently.” – Exercise Adherence in Persons with PD (Ellis, 2009 – pdonlineresearch.org)
  8. Stick with it.If you stop exercising, the positive effects you’ve worked so hard to achieve through exercise will decline and disappear. People with PD who exercise do better than those who don’t.
    1. “Discontinuation of exercise in advance of brain injury may…leave the brain more vulnerable to degeneration.” ). – Motor Enrichment and the Induction of Plasticity Before or After Brain Injury (Kleim et al, 2004)
  9. Exercise for your whole being.Exercise isn’t just good for your body. Other issues related to Parkinson’s disease – like depression, sleep and constipation could also be positively affected by exercise and activity.
    1. “…Exercise may be conceptualized as a non-pharmacological equivalent of antidepressant medication, which is presumed to exert its effects by modifying brain chemical systems.” – Exercise for Mood and Anxiety Disorders (Smits & Otto, 2009)
  10. Use exercise to take control of your PD.People with Parkinson’s are robbed of so much control in their lives, but exercise is one thing you can control and in the process, create a better quality of life for yourself.
    1. “Exercise can be fun and is good for you. It can give you more 
confidence and more energy. More importantly, exercise is something that you can do to help manage your disease and improve your quality of life.” – Be Active! An Exercise Program for People with Parkinson’s Disease (Ellis, Rork & Dalton et al, 2008

Parkinson's Imaging Agent Descheduled

September 15, 2015
The imaging agent, ioflupane I 123 (DaTscan; GE Healthcare), has been removed from the schedules of the US Controlled Substances Act, meaning that it will be more widely available for use in the diagnosis of Parkinson's disease and associated conditions.
Ioflupane I 123 is a US Food and Drug Administration–approved imaging agent that allows an assessment of the integrity of the striatal dopaminergic system via the dopamine transporter to help physicians determine whether patients have essential tremor or a parkinsonian syndrome movement disorder, such as Parkinson's disease.
Since approval in 2011, it has been listed by the Drug Enforcement Administration (DEA) as a Schedule II controlled substance, which has restricted the drug's use to only those healthcare professionals and imaging facilities registered with the DEA and able to comply with all of the requirements for the appropriate prescribing, storage, use, and disposal of Schedule II controlled substances.  
But the DEA has now descheduled ioflupane I 123, lifting these restrictions, making it easier for imaging specialists to order and administer it in their facilities.
DaTscan is a radioactive drug injected into the bloodstream to help image areas of the brain using single-photon emission computed tomography (SPECT). SPECT with DaTscan, along with other medical tests, aids in diagnosis of a Parkinsonian syndrome or essential tremor. Parkinsonian syndromes include Parkinson's disease, multiple system atrophy, and progressive supranuclear palsy.
DaTscan was not designed to differentiate among these different forms of parkinsonian syndrome, the company release notes. Its effectiveness as a screening or confirmatory test and for monitoring disease progression or response to therapy has also not been established.
Quoted in a GE Healthcare press release, Ted Thompson, JD, chief executive officer of the Parkinson's Action Network, said, "The Parkinson's Action Network applauds the DEA for descheduling the active ingredient in DaTscan and allowing many more people to have access to this important diagnostic tool. Having this tool available for people with suspected Parkinsonian syndromes and essential tremor may help them to receive appropriate diagnosis and treatment sooner."

Saskatchewan scientists work with Harvard on new Parkinson's research


THE CANADIAN PRESS  
SASKATOON - Researchers at the University of Saskatchewan are teaming up with colleagues at Harvard Medical School in Boston to use stem cells to treat Parkinson’s disease.
Parkinson's disease attacks the cells in the brain that create dopamine, a chemical that carries action signals through your brain.
Dr. Ivar Mendez of the Saskatchewan Brain Repair Program at the Saskatoon university says when this happens, it causes the loss of function, but new research is hoping to restore those.
The process involves taking stem cells from a patient's skin or blood, and converting them into a brain stem cell which is rich in dopamine neurons.
Once they are injected into the brain, the dopamine is released and the broken links begin to be repaired.
Currently, a dopamine chemical is injected into the body with heavy immune suppression so the body will accept the chemical. In the new method, because a person's own cells are used, the theory is their body will accept the treatment more easily.
Mendez began transplanting cells that produce the neurotransmitter dopamine into patients in the late 1990s while he was at Dalhousie University. All 10 patients implanted with these cells improved significantly.
Dr. Ole Isacson of Harvard says if they are successful in this research project, the cells being injected will help restore some function in patients within the first nine months of treatment.
Clinical trials are expected to start within two to three years.
