Longitudinal regional cortical acetylcholinesterase hydrolysis reductions compared with normal controls. Serial PMP k3Z-score maps over two-time points in Parkinson’s disease compared with normal older control persons. Pronounced interval reductions (Z-scores < −2) were found in the occipital association cortices, posterolateral and inferior temporal regions, precuneus, posterior cingulum and to a lesser degree in the anterior mesofrontal regions were seen in the Parkinson’s disease group.
