At the end of each year, it is a useful practise to review the triumphs (and failures) of the past 12 months. It is an exercise of putting everything into perspective.
2017 has been an incredible year for Parkinson’s research.
And while I appreciate that statements like that will not bring much comfort to those living with the condition, it is still important to consider and appreciate what has been achieved over the last 12 months.
In this post, we will try to provide a summary of the Parkinson’s-related research that has taken place in 2017 (Be warned: this is a VERY long post!)
The number of research reports and clinical trial studies per year since 1817
As everyone in the Parkinson’s community is aware, in 2017 we were observing the 200th anniversary of the first description of the condition by James Parkinson (1817). But what a lot of people fail to appreciate is how little research was actually done on the condition during the first 180 years of that period.
The graphs above highlight the number of Parkinson’s-related research reports published (top graph) and the number of clinical study reports published (bottom graph) during each of the last 200 years (according to the online research search engine Pubmed – as determined by searching for the term “Parkinson’s“).
PLEASE NOTE, however, that of the approximately 97,000 “Parkinson’s“-related research reports published during the last 200 years, just under 74,000 of them have been published in the last 20 years.
That means that 3/4 of all the published research on Parkinson’s has been conducted in just the last 2 decades.
And a huge chunk of that (almost 10% – 7321 publications) has been done in 2017 only.
So what happened in 2017? Continue reading
Something different for you today – a history lesson…with some science.
The history of Parkinson’s disease dates back well before Dr James Parkinson made his observations about 6 patients 199 years ago (oh, big anniversary coming up! Who knew)
But it may surprise you to know that the history of Parkinson’s disease dates back before even Jesus turned up.
You actually have to go back a long back in order to get to the beginning…
If you were demonstrating the early features of Parkinson’s disease in the year 500 BCE, there was really only one place in the world that you wanted to be:

Not only did India have a extremely sophisticated system of diagnosis for what we call Parkinson’s disease, but they also have a VERY effective treatment!
Don’t believe me? Read on.
Around 5000 BCE, the wise and farsighted members of the Indian medical establishment began pooling their collective knowledge – firstly in an oral form, but then eventually in a written format. That written material became the text known as the Ayurveda (/aɪ.ərˈveɪdə/; Sanskrit for “the science of life” or “Life-knowledge”).
It can not be understated how sophisticated the Ayurveda was for its time. This was a period bridging the ‘new stone age’ and the ‘Bronze age’. People’s understanding of medical afflictions was basically limited to what the Gods and evil spirits were doing to them.
The earliest account of Parkinson’s disease features in the Ayurveda was compiled by Susruta (the 600 BC author of “Susruta Samhita”). He described slowness (cestasanga in Sanskrit) and akinesia (cestahani) in certain individuals, and also (curiously) reported that certain poisons could cause rigidity and tremor.
To demonstrate to you just how sophisticated the Ayurveda was, consider this: when faced with a person exhibiting tremor a practitioner using the Ayurveda could chose between six different types of tremor:
- Vepathu (a generalised tremor)
- Prevepana (excessive shaking)
- Kampa vata (tremors due to vata)
- Sirakampa (head tremor)
- Spandin (quivering)
- Kampana (tremors)
Number 3 (Kampa vata) on that list is what we now refer to as Parkinson’s disease. Kampa basically means ‘tremor’, while Vata is more difficult to define – it is essentially the property/force that governs all movement in the mind and body (blood flow, breathing, etc – even the movement of thoughts).
Since the 3rd century BCE, practitioner of the Ayurveda have been using the seeds of Mucuna pruriens in treating conditions of tremor.
