The vocabulary associated with Lewy pathology causes confusion. [27] Lewy body dementia (the umbrella term that encompasses the clinical diagnoses of dementia with Lewy bodies and Parkinson's disease dementia) differs from Lewy body disease (the term used to describe pathological findings of Lewy bodies on autopsy). [27]
Lewy bodies are the inclusion bodies – abnormal aggregations of protein – that develop inside neurons affected by Parkinson's disease (PD), the Lewy body dementias (Parkinson's disease dementia and dementia with Lewy bodies (DLB)), and some other disorders.
The vocabulary of diseases associated with Lewy pathology causes confusion. [15] Lewy body dementia (the umbrella term that encompasses the clinical diagnoses of dementia with Lewy bodies and Parkinson's disease dementia) differs from Lewy body disease (the term used to describe pathological findings of Lewy bodies on autopsy). [15]
This Lewy body pathology selectively travels through the CNS, targeting thin and largely unmyelinated neurons. Braak et al., therefore, developed a staging system that characterizes disease progression. This system is divided into six different stages, with each stage being attributed to abnormal pathology in particular neurological structures.
[15] [16] [17] [10] A common combination of brain pathologies—with Alzheimer's disease pathology, Lewy body pathology, and LATE-NC in the same brain—tends to affect younger individuals (often <75 yrs of age) and, on average, is associated with more aggressive (faster) cognitive deterioration.
The DNA repair function of alpha-synuclein appears to be compromised in Lewy body inclusion bearing neurons, and this may trigger cell death. Study of synucleinopathy mouse models of Parkinson's disease indicates that alpha-synuclein pathogenesis is associated with increased DNA damage and activation of the DNA damage response.
Parkinson's disease dementia can only be definitively diagnosed after death with an autopsy of the brain. [6] The 2017 Fourth Consensus Report established diagnostic criteria for PDD and DLB. [ 9 ] The diagnostic criteria are the same for both conditions, except that PDD is distinguished from DLB by the time frame in which dementia symptoms ...
The Dementia with Lewy Bodies Consortium (DLB Consortium or DLBC) is an international multidisciplinary collaboration of researchers interested in the dementia with Lewy bodies. [1] It first convened in Newcastle upon Tyne, England, in October 1995. [1] Between 1995 and 2005, it issued three DLBC Consensus Reports on dementia with Lewy bodies. [2]
