Parkinson's is a devastating disease for those living with the condition and currently there is no cure. Diagnosis can also be slow as there are no blood tests to detect it.
But now mathematician Max Little has come up with a non-invasive, cheap test which he hopes will offer a quick new way to identify the disease.
Watch his presentation at a TED conference in Edinburgh earlier this year, explaining the principle of the test and see how you can help to make it better.
Anyone can call and they need to state whether or not they have been diagnosed with the disease.There is also a website where people can find out more about the project. "The more people that call in, the better," he said. "If we get 10,000 recordings we'd be very happy but even a tenth of that would be great,"
