Parkinson's disease: New research could reveal early causes
Health news from the BBC
Listening to the "conversations" of brain cells as they develop could help researchers to better understand the early causes of Parkinson's disease.
Parkinson's is the second most common neurodegenerative condition after Alzheimer's disease.
The disease causes parts of the brain to become progressively damaged over many years.
But relatively little is known about its early stages, as much of the damage happens before symptoms appear.
Now a Cardiff University team is using cutting-edge techniques to help understand the disease's earliest causes.
By taking cells "back in time", the researchers hope their findings could aid the search for new treatments.
