Parkinson's disease dementia is the diagnosis when Parkinson's disease is already ...
In DLB, there is an identifiable set of early signs and symptoms; these are called the prodromal, or pre-dementia, phase of the disease. [21] [22] These early signs and symptoms can appear 15 years or more before dementia develops. [21]
DLB is diagnosed when cognitive symptoms begin before or at the same time as parkinsonism. Parkinson's disease dementia is the diagnosis when Parkinson's disease is well established before the dementia occurs; that is, the onset of dementia is more than a year after the onset of parkinsonian symptoms.

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]
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.
