Abstract

Lewy bodies and Lewy neurites are the hallmark neuropathologic findings in Parkinson disease, Parkinson disease with dementia, dementia with Lewy bodies, and other alpha-synucleinopathies. They have also been described in the brains of normal older individuals and referred to as incidental Lewy body disease. The purpose of this study was to determine the prevalence of Lewy bodies and Lewy neurites (Lewy body pathology [LBP]) in 139 autopsies from our normal volunteer control group of the University of Kentucky Alzheimer's Disease Center. All subjects were followed longitudinally and were cognitively normal and without any type of movement disorder, neuropsychiatric features, or other CNS findings. The brains of 33 of 139 normal subjects contained LBP in various regions. The most common regions involved were the medulla (26%), amygdala (24%), pons (20%), and midbrain (20%). No mean statistical differences were found between those with and without LBP on any demographic or cognitive variable, Braak stage, or neurofibrillary tangle and neuritic plaque quantitation. An explanation for the high prevalence of LBP in our elderly, well-educated study group is not clear, although it does not seem to be related to aging or the presence of Alzheimer disease pathology. Overall, our findings support the concept that incidental Lewy body disease most likely represents preclinical or presymptomatic Parkinson disease, Parkinson disease with dementia, or dementia with Lewy bodies.

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.
