Brain scans can detect Parkinson’s years before symptom appear, says study

Parkinson's disease is the second most common neurodegenerative disorder, after Alzheimer's disease. The disease is characterised by movement and cognitive problems but is known to become established in the brain a long time before patients are diagnosed.

People with Parkinson’s disease have build-ups of the protein a-synuclein in the brain. While there is no clear cause for most people, a minority of cases are caused by genetic mutations. (Photo: istock/Getty Images)

Brain scans can detect the earliest signs of Parkinson’s disease — many years before patients show any symptoms — according to a Lancet study published Thursday.
