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]
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]
Lewy neurites are abnormal neurites in diseased neurons, containing granular material and abnormal α-synuclein filaments similar to those found in Lewy bodies. [20] Like Lewy bodies, Lewy neurites are a feature of α-synucleinopathies such as dementia with Lewy bodies, Parkinson's disease, and multiple system atrophy. [21]
Lewy body dementia symptoms. Lewy body dementia can cause various symptoms that may impact a person’s cognition, movement, sleep and behavior. According to the NIA, those can include: Hallucinations
Lewy Body Dementia (LBD) is the second-most common form of dementia after Alzheimer’s disease; However, unlike most well-known forms of dementia, LBD isn’t characterized by memory loss.
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 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.
