This year marks 200 years since Dr James Parkinson wrote his essay defining the condition we now know as Parkinson’s disease – but there is still no cure. For this debate piece in our special #UniteForParkinsons series, we speak to Parkinson’s experts around the world to find out how close we could be to a big leap in the search for better treatment and ultimately a cure
A ‘breakthrough’ is defined as a sudden increase in knowledge, improvement in technique, or fundamental advancement in understanding. But what breakthroughs are Parkinson’s researchers and campaigners working towards? And how close are we to achieving those breakthroughs? Here, we ask three world-renowned Parkinson’s experts – Dr Michael Okun, Professor Baastian Bloem and Susanna Lindvall – to share their personal opinions and predictions on each of their fields of expertise.
“Breakthrough ideas and therapies stretch far beyond a single drug”
Dr Michael Okun, Adelaide Lackner professor and chairman of neurology at the Univeristy of Florida
The point that I emphasise with my patients is that breakthrough ideas and therapies in Parkinson’s disease stretch far beyond a single drug or stem cell. There is, in fact, a broader and more exciting picture and portfolio of breakthroughs spanning drug, cell, vaccine, device, genetics, care, and behaviour. Patients and families with personal investments in Parkinson’s disease should be informed and updated about all of the potential breakthrough therapies.
Andy Siderowf and colleagues at the University of Pennsylvania’s National Parkinson Foundation (NPF) Center of Excellence, took another approach to constructing an economic model. The Penn investigators were interested in the ‘economic consequences of slower rates of Parkinson’s progression’. They used a technique called a Markov model and predicted the potential savings associated with slowing Parkinson’s disease progression. Slowing progression by 20% saved the health care system US$60,657 per patient. Stopping disease progression saved US$442,429 per patient.
It is now clear that the weather forecast will be predicting a future storm of Parkinson’s disease cases. This storm will be accompanied by a downpour of large hospital bills and an insurmountable economic burden. The newly diagnosed Parkinson’s disease cases, when added to the existing patients, will have a social and economic impact on all countries and cultures. It will be important that we advocate for a strategic investment from all nations of the world.
One of the most common questions I receive from Parkinson’s disease patients and families is ‘What will be the next breakthrough therapy?’ Because of the complexity of the disease, each person possesses a different combination of bothersome symptoms. This complexity means that the answer to the next breakthrough therapy will vary patient to patient, and it could be a breakthrough in care as well as possibly a new device or drug. We will need to expand our notion of breakthroughs, and we will need to harness this knowledge to reduce the burden of Parkinson’s disease.
“I see a much greater role for informed, engaged patients”
Professor Bastiaan Bloem, MD, PhD, medical director, Parkinson Center Nijmegen
Breakthroughs in the area of Parkinson’s disease will come from two main directions: the cure and the care. My own research and innovation focus is exclusively on care issues. The major breakthrough that I foresee here is a much greater role for fully informed and engaged patients as equal partners in healthcare, who have easy access to integrated healthcare networks of well-trained professionals who work according to a value-based healthcare concept.
Care will be delivered largely outside institutions and within the patient’s own home environment, and increasingly via telemedicine approaches. This and other technological developments will help to drive these aforementioned innovations. Implementing this into the western world will take at least 10 more years, and unfortunately, much longer in less developed countries.
“In the next 10 years I hope we will have effective methods for early diagnosis”
Susanna Lindvall, vice-president of the European Parkinson’s Disease Association (EPDA)
Until now, Parkinson’s treatments have focused on symptom management in terms of drug-based treatments and surgical treatments such as deep brain stimulation. Now, there are several drugs in the pipeline – such as MSDC-0160, a drug originally created to treat Type-2 diabetes and the Transeuro trial of cell therapy (transplantation).
In the coming 10 years I hope we will have effective methods for early diagnosis. Right now, researchers have developed a new test that is able to detect abnormal alpha-synuclein in the spinal fluid of people with Parkinson’s with remarkable specificity and sensitivity, at an early stage of the disease. It is early days, but the test is promising. There is also a new neuro-protective strategy where LRRK2 kinase inhibitors are being trialled as therapies for Parkinson’s disease. Researchers have discovered an interaction in neurons that contributes to Parkinson’s disease, and they have shown that drugs currently in development may block the process. The hope is that these will bring major improvements in the quality of life for people with Parkinson’s – life expectancy will improve and the progression of the condition may be slowed or even stopped.
Michael Okun, MD
Michael is an internationally renowned neurologist and leading researcher. He is currently the Adelaide Lackner professor and chairman of neurology at the University of Florida and is the medical director at the US-based organisation, the Parkinson’s Foundation.

Could traumatic brain injury accelerate the onset of Parkinson’s disease?
Undergoing a traumatic brain injury (TBI) – a sudden injury that damages the brain – may be linked to Parkinson’s onset at an earlier age, new research suggests. The study, led by researchers in the US, examined data from the National Alzheimer’s Coordinating Centre (NACC) database and assessed whether TBI was associated with age of disease onset, survival and the degeneration of dopamine-producing nerve cells in the brain. They found that while there was no significant association with age of death or greater impact on dopamine-producing nerve cells, results showed that TBI was linked to a 4.9-year earlier age of Parkinson’s onset. Reflecting on the results, the researchers wrote that traumatic brain injury “appears to accelerate Parkinson’s onset without altering age of death”. However, the researchers also cautioned that “the nature of this relationship remains unclear”.
NASA astronaut who lived with Parkinson’s disease has died
“When I got diagnosed with Parkinson’s I thought it was over,” US astronaut Michael “Rich” Clifford once said, in a webcast conversation with Parkinson’s expert Dr Ray Dorsey. But when US space agency NASA offered him another opportunity to board a space shuttle, despite the onset of Parkinson’s symptoms, he didn’t hesitate. “And it was as easy as that.” Now, nearly 30 years since his final venture into space, Clifford has died due to complications from Parkinson’s disease. He leaves a legacy of three journeys into space, several awards for his services to the space programme – including the NASA Space Flight Medal – and a history of advocacy for people with Parkinson’s. In a 2013 conversation with the Michael J Fox Foundation, Clifford said: “Everyone with Parkinson’s handles it differently. Don’t let it get in the way of living. “Life is too good. Keep going. The sky’s the limit.” Image credit:…
Sir Billy Connolly opens up about life with Parkinson’s disease in new documentary
Scottish comedian, actor and musician Sir Billy Connolly shared updates about his experiences with Parkinson’s disease in a new documentary for UK channel ITV. The documentary, titled ‘Billy Connolly: My Absolute Pleasure’, featured the comedian discussing moving to his new home in Florida Keys, US, writing his first autobiography ‘Windswept and Interesting’, and how he’s managed living with Parkinson’s. Opening up about living with the condition, Connolly said in the documentary: “Parkinson’s disease has taken a lot from me. I can’t play the banjo anymore; I can’t smoke cigars. It’s taken more and more of what I like.” Connolly also said he behaves a certain way so his children “don’t think I’m a dead loss”. Despite this, Connolly remains upbeat about managing Parkinson’s: “You have to have a Glasgow attitude and say: ‘Oh, you think you’ve got me beat? Try this for size.’ I just deal with it. If I…
