The authors of this review consider whether Dementia With Lewy Bodies (DLB) and Parkinson’s Disease Dementia (PDD) are actually two distinct conditions, as the official “Diagnostic and Statistical Manual of Mental Disorders” 5th Edition (DSM–5) would suggest, or whether the underlying similarities imply they may be different manifestations of the same disease. Still unsure.

Differential Diagnosis: Early Developments
“Differentiation of Parkinson’s disease (PD) from the various types of atypical parkinsonism (AP) such as multiple system atrophy (MSA), progressive supranuclear palsy (PSP), dementia with Lewy bodies (DLB), corticobasal syndrome (CBS) and vascular parkinsonism (VP), can be challenging, especially early in the disease course”.
Work on a diagnostic tool which might help differentiate between various disorders at an early stage:
