Today saw the publication of one of my favourite stories of Parkinson’s research.
It is a tale of courage, serendipity, hard work, and (most importantly) an idea for a research project that came from the Parkinson’s community, but has now opened new doors for researchers and could have important implications for everyone.
In 2012, former nurse Joy Milne was attending a Parkinson’s support group meeting in Edinburgh (Scotland) when she bravely asked the scientist presenting research that day, “Do people with Parkinson’s smell different?”
What happened next is likely to become that stuff of legend.
In today’s post, we will discuss the back story, review a new research report investigating the smell of Parkinson’s, and consider what the results could mean for the Parkinson’s community.

In 1963, Dr. Denis G. Osborne – from the University College in Dar es Salaam – was invited to give a lecture on physics to the students at Magamba Secondary School (Tanganyika, Tanzania). At the end of his lecture, a 13 year old student, named Erasto Mpemba, stood up and asked Dr Osbrone:
“If you take two similar containers with equal volumes of water, one at 35 °C (95 °F) and the other at 100 °C (212 °F), and put them into a freezer, the one that started at 100 °C (212 °F) freezes first. Why?”
The question was met by ridicule from his fellow classmates.
But to his credit, Dr Osborne went back to his lab and conducted some experiments based on the question, confirming Mpemba’s observation. Together they published the results in 1969, and the phenomenon (the process in which hot water can freeze faster than cold water) is now referred to as the Mpemba effect.

The point is: All scientific discoveries start with an observation, followed by an experiment.
And scientists do not have a monopoly on this.
There have been many cases of ‘laypeople’ – like Erasto Mpemba – making important observations. And recently the Parkinson’s world had a perfect example of this. It’s very own Erasto Mpemba moment.
