Takeaway
No racial differences were found in Lewy body frequency, distribution, and association with dementia and parkinsonism between Black and white decedents.
Why this matters
Most existing research on the association of Lewy bodies with age-related conditions such as dementia, Parkinson’s, and olfactory dysfunction include mainly white participants.
There are racial differences in the prevalence if Alzheimer’s and Parkinson’s disease between Black and white individuals, but the reasons behind this are largely unknown.
