Researchers in Scotland have discovered that around five per cent of people diagnosed with Parkinson's disease show little more than hand tremors or stiffness, making them questionable recipients of the judgment.
The Daily Telegraph detailed the findings of Scottish researchers, who understand that millions of pounds are being wasted on unnecessary drugs every year for those who do not have the full effects of the neurodegenerative disorder.
One of the authors of the report Dr Kieran Breen explained that no two people with Parkinson's will experience the same effects, due to a wide range of issues.
He continued: "The three main characteristics are tremors, slowness of movement and stiffness, but not everyone will have all three symptoms. The patients should be referred to neurologists with more expertise and they will make a much more accurate diagnosis."
Dr Kieran Breen is the current director of research and development at the Parkinson's Disease Society, working under the expert guidance of the charity's chief executive Steve Ford.
