MRI Scan

MRI scan reveals cognitive decline in Parkinson's patients

An MRI scan that detects atrophy patterns in the brains of Alzheimer's patients also can reveal cognitive decline in Parkinson's patients, a new study finds. Investigators say this technology can predict which patients with Parkinson's disease will experience long-term cognitive decline or develop dementia in the future. About 4 in 5 Parkinson's patients typically develop dementia as the disease progresses. The study was published online in the journal Brain.
