Widespread Brain Atrophy Detected in Parkinson's Disease With Newly Developed Structural Pattern, University of Pennsylvania Study

Atrophy in the hippocampus, the region of the brain known for memory formation and storage, is evident in Parkinson's disease (PD) patients with cognitive impairment, including early decline known as mild cognitive impairment (MCI), according to a study by researchers in the Perelman School of Medicine at the University of Pennsylvania. The study is published in the December issue of the Archives of Neurology, one of the JAMA/Archives journals.
