Scottish scientists have created an algorithm that can detect a side effect of Parkinson’s treatment that causes involuntary jerking movements.
Prolonged prolonged exposure to the dopamine replacement drugs can lead to dyskinesia, causing involuntary jerking and spasms of the whole body.
Heriot-Watt University academics have conducted clinical studies which prove their algorithm reliably detects the condition. They are now using their study to develop a new home monitoring device for patients to help their clinician adapt and improve treatment.
Dr Michael Lones, associate professor of computer science at the Edinburgh university, said: “The problem is that, as Parkinson’s disease worsens over time, the dose required to treat the motor features increases, which increases the risk of inducing dyskinesia, or making it more severe and prolonged for patients who already have it.
“Patients don’t see their clinicians that frequently, and medication only changes at regular review periods. So it’s very difficult for clinicians to know when dyskinesia is occurring.
“A better solution would be a portable device that identifies and monitors dysk- inesia while patients are at home and going about day-to- day life, broadcasting data to their clinicians through simple mobile technology.”
The motor features of Parkinson’s Disease, such as tremor, postural instability and a general slowing of movement, are caused by a lack of dopamine. Patients get replacement drugs such as levodopa, but prolonged exposure to the substances can lead to dyskinesia.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
