Study reveals cognitive problems associated with Parkinson's

Scientists have shed some light on how Parkinson's disease affects cognitive impairment.

According to researchers at Queen's Centre for Neuroscience Studies in Canada, people with Parkinson's disease are actually better at performing automated tasks than people without the disease, HealthCanal.com reports.

It is when the type of task being attempted becomes more difficult that impairment in the brain begins to reduce a person's effectiveness.

Lead author Ian Cameron says that these findings are important because it shows that people with Parkinson's disease are naturally drawn to automated rather than prepared responses.

"We often think of Parkinson's disease as being a disorder of motor function," added co-author professor Douglas Munoz.

"But the issue is that the same circuit can affect more cognitive functions like planning and decision-making."

The charity Parkinson's UK estimates that one in every 500 people in the UK is living with Parkinson's disease, equating to around 120,000 people.
