Good morning. Bonjour. Thank you very much for the opportunity to address members of Parliament in the context of this subcommittee to talk about something that each of us feels very passionate about, namely, neurological diseases and how to fight them, particularly with respect to Parkinson's disease.
I'd like to give you a very brief background on my role and the work that we do on Parkinson's research, and then maybe finish with a few thoughts from an international perspective.
I grew up in Vienna, Austria. I went to medical school there and did internal medicine training. I then went to the United States and spent 16 years there training in scientific research on Alzheimer's disease, learning to become a neurologist and then focusing on becoming a physician for Parkinson's disease patients and other patients with movement disorders.
In late 2006, I had the opportunity to come to Canada, in large part through the support of the Canadian government, to join the neuroscience community here. For the record, I wish to state that I'm extremely grateful and very happy to be here and to be part of a very vibrant community. I fully identify with the Canadian values, not just regarding societal priorities but also regarding Canada's scientific conduct.
What I really like about being in Canada is that, in my opinion, it's very innovative and collaborative. I think you've heard it already from Joyce and you'll hear it from the other two speakers. By that I mean that our scientific approach is often very much team-based. That is a critical element for succeeding in research today.
Canadian science is also invariably of high quality and is internationally respected. It is also, in some areas, underfunded. Such a comment, one could argue, is typical of a researcher, but in the following minutes, I'd like to draw your attention—Dr. Stoessl is going to do this too—to the fact that we actually see ourselves also as innovators and as engines of a knowledge-based and health-care economy rather than as self-serving occupants of an ivory tower.
In my work I spend approximately 70% of my time directing a laboratory, and 15% to 20% of my time is spent working with patients. I spend a small amount of time directing a program that I've built in Ottawa, namely a Ph.D. program that allows students to become proficient in two languages—the language of medical care and the language of scientific conduct. That's a passion that all of us share.
When I finished residency training in Boston, having focused on Alzheimer's disease, I switched to Parkinson's disease for a number of reasons, one of which was that at that time, in 1997-98, in the study of Parkinson's disease a genetic revolution was taking place. In other words, we all of a sudden had unprecedented opportunities to gain new insights into this critical illness. As you've heard already and as you will hear, obviously our society will be faced with many more patients with dementia and Parkinsonism over the decades to come. When you get genetic clues or insights, they give you great new opportunities, because you can try to understand the disease better and translate it into better models, and then come up with new regimens and drug therapies to combat it.
To give you an example, when people first found out how cholesterol is abnormally regulated, a team led by Brown and Goldstein tackled the problem of how cholesterol is normally internalized and processed. Ultimately that led to a new class of drugs that are called statins, which many of us take and our patients often take to lower cholesterol and prevent heart attacks and strokes. This was a critical insight whereby a disease process was understood and translated successfully into new drugs. It started a whole new industry and helped economies around the world.
So in many ways, in Parkinson's disease we had this genetic revolution that started to take place 15 years ago. Believe it or not, today we have more clues as to how faulty genes lead to Parkinson's than the Alzheimer's field has. That gives us a great opportunity.
If you look at one hundred people who have Parkinson's, 10% to 15% will have inherited a faulty gene from their mother or father, and 5%--five out of a hundred--may have had a horrible environmental or occupational accident and had too much manganese exposure or pesticide exposure and will get Parkinson's. For the remainder, those in the middle, the 80%, there is a combination of environment and genes playing together in what constitutes a complex disease.
So you can see that in many ways Parkinson's is complicated and also complex. But that's not new to us. The same thing happens in Alzheimer's, diabetes, coronary heart disease, and in hypertension obesity: environment and genes. The real challenge will be how we understand it better to ultimately translate it into a cure, which we all are passionate about.
The further thing that complicates Parkinson's is that the incubation time, if you will—the time these diseases develop—is 15 to 20 years. Sometimes it starts with loss of smell, and sometimes with constipation, believe it or not.
For us to capture the whole animal, to see the whole elephant, will take a lot of work from different angles. I strongly believe--and that's the one thing I want to convey to you--that although it's complex and complicated, we can solve that riddle. We can crack that nut. We have the expertise in Canada to make a major contribution to this.
The community of Canadian researchers is well positioned to further explore the mechanisms that lead to Parkinson's and translate that into drugs. That will be done in conjunction with big pharmaceutical companies, with small biotech companies. It will generate new economies, and new businesses as well, as I'll point out to you in a moment.
Essentially what we do today, in part initiated by a former teacher of mine, Dr. Oleh Hornykiewicz, who worked in Toronto for many years, is the same thing that was put in place for Parkinson's 50 years ago. We know how to treat tremors or slowness a bit, but we haven't stopped the disease.
When you have pneumonia, you can now cure the disease because you give an antibiotic that stops the bug, the virus, the bacteria. We can't do this with Parkinson's. We can only treat the tremor a bit. We really need to go to cause-directed treatment. We have to kick at the root cause.
I think in terms of the effort, although it sounds daunting, we can succeed. We have certain elements in place that are unique to Canada. A famous bacteriologist once said that to succeed in science with a medical problem, you need four things: talent, endurance, monetary support, and luck. In Canada, we have talent. We have endurance. With the proper infrastructure and support, we can force the luck. We can crack the nut and make a difference.
Why am I optimistic? We have these critical elements in place and we have the precedent in Canada. I want to mention two things that I think are fantastic examples of how we can solve and proceed and succeed.
One is the Centre for Stroke Recovery, which was built with a large support from the Canadian government. It allowed Dr. Hakim and his colleagues, in the larger province of Ontario and elsewhere in Canada, to change how we deliver stroke care, to come up with new rehabilitation efforts and models, and to research how we help stroke patients.
The second one is a series of national centres of excellence that were built in Vancouver: the PROOF concept, which is led by Dr. Bruce McManus. It has revolutionized how we think about heart disease and kidney disease. Now the United States is copying it and the FDA has approved their approaches.
We can generate new economies, new approaches by succeeding in putting our heads together and collaborating.
In closing, I want to mention two small but very significant examples from the south of the border. I have come to admire how the Americans tried to tackle this. One is the program that is called the Morris K. Udall Centers of Excellence for Parkinson's Disease Research. Mr. Udall was a House of Representatives member for many years, and he was revered. He died of Parkinson's.
The United States put research grants together and generously funded ten centres to tackle Parkinson's. One particular example led to an amazing new economic development, such as at my centre. I was at the Brigham and Women's Hospital in Boston, which received one of these Udall centre awards. One of my patients teamed up with one of our scientists; an angel donor started a company that subsequently attracted $40 million to do Alzheimer's and Parkinson's trials.
The return on a $5 million investment by the government, now having $44 million invested in new research and clinical trials for cause-directed treatment, was unprecedented. Given the fact that the Canadian research dollar goes much further than the United States research dollar, the return on investment in our situation under similar circumstances could be 25-fold to 27-fold bigger.
Why not, for instance, think about the idea of creating something similar to that within the Canadian Institutes of Health Research? It could be called the “Pierre Elliot Trudeau Centre of Excellence in Parkinson's Research”, given the notion that the former Prime Minister died of complications from this disease.
I want to convey to you: yes, we can. With this attitude we can not only solve the problem, we can also benefit as a society from it.
A second example, briefly mentioned, is in Alzheimer's disease, where a collaborative effort between--
