Differences in neuropathologic characteristics across the Lewy body dementia spectrum
Open accessAbstract
BACKGROUND: The objective of this comparative neuropathologic study was to determine the extent to which dementia with Lewy bodies (DLB) and Parkinson disease dementia (PDD) are distinct entities or part of a continuum with respect to the duration of parkinsonism. METHODS: We evaluated the relationship between cortical alpha-synuclein pathology, plaques (Consortium to Establish a Registry for Alzheimer's Disease [CERAD]), tangles (Braak staging), and cholinergic deficits (choline acetyltransferase in temporal cortex) in 57 prospectively assessed patients (29 DLB, 28 PDD), confirmed at autopsy. The PDD group was divided according to the median duration of parkinsonism prior to dementia. RESULTS: There was an association between longer duration of parkinsonism prior to dementia and less severe cortical alpha-synuclein pathology (chi(2) 10.4, df 2, p = 0.006) and lower CERAD plaque scores (chi(2) 26.6, df 9, p = 0.002), but not Braak staging. These findings were confirmed in a further correlation analysis, which also identified an unexpected correlation between more pronounced cortical cholinergic deficits and longer duration of parkinsonism prior to dementia (R = -0.37, p = 0.04). CONCLUSION: While there is a clear relationship between the duration of Parkinson disease prior to the onset of dementia and key neuropathologic and neurochemical characteristics, there is a gradation of these differences across the dementia with Lewy bodies/Parkinson disease dementia spectrum and the findings do not support an arbitrary cut-off between the two disorders.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
