Findings of a latest Queen’s research have proposed that individuals suffering from the Parkinson’s disease have better ability of performing programmed, automated errands than the normal people.
But Parkinson’s patients encountered difficulty when switching from simple to complex tasks, the researchers found.
A team of researchers from the Queen's Center for Neuroscience Studies initiated the present study that hoped to develop a better understanding of the ailment that affects the cognitive functioning of the brain.
"We often think of Parkinson's disease as being a disorder of motor function," Douglas Munoz, director of the Center and a Canada Research Chair in Neuroscience said. "But the issue is that the same circuit can affect more cognitive functions like planning and decision-making.”
Study details
For the study, the researchers conducted examination on people suffering from the Parkinson’s disease and a control group of normal people.
All the study subjects were asked to look at a light, and it was observed that Parkinson’s patients performed much better than the normal candidates. But, when the people were asked to look away from the light, the first group faced difficulty.
Ian Cameron, a PhD student at the Queen’s institute, is of the opinion that the findings of the study not only point out that the cognitive balance of the patients was affected due to the medications, but also showed the patient getting upset when asked to perform an alternate task.
The researchers are now further working to find out which part of the brain is affected by the currently available drugs that are prescribed to people suffering from Parkinson’s disease.
“Functional brain imaging in Parkinson’s patients will be used to help out in this study,” revealed Cameron.
The findings of the study have been published in an international interdisciplinary journal of cognitive and behavioural neuroscience, ‘Neuropsychologia’.
