Parkinson’s disease dementia and dementia with lewy bodies: the same disease or two entities?

Joint Event on 5th International Conference on Spine and Spinal Disorders & 15th International Conference and Exhibition on Alzheimers Disease, Dementia & Ageing

Dementia with Lewy bodies (DLB) and Parkinson's Disease Dementia (PDD) share many clinical, neurochemical and pathological features with each other as well as with Alzheimer's disease. The clinical features of DLB and PDD include cognitive impairment, parkinsonism and visual hallucinations. Their diagnosis is based on a distinction concerning the time of motor and cognitive symptoms, as early as cognitive impairment in DLB and later onset following that of motor symptoms in PDD. Pathological hallmarks, cortical and subcortical α-synuclein/Lewy body plus β-amyloid and tau-pathologies are similar. Despite clinical overlap, clinical differences at onset indicate different entities and they have been considered as subtypes of α-synuclein associated disease spectrum (Lewy body diseases) and classified into DSM-5 as two separate entities of major neurocognitive disorders with Lewy bodies. In vivo PET and postmortem findings revealed cortical atrophy, elevated cortical and limbic Lewy pathologies (with APOEε4) and a higher prevalence of Alzheimer pathology in DLB than PDD. While these hallmarks may account for earlier onset and greater severity of cognitive impairments in DLB, PET studies revealed no differences in cholinergic and dopaminergic deficits. Based on recent publications, including the fourth consensus report of the DLB consortium, we prefer to view DLB and PDD as two entities or subtypes of a unified nosological continuum-α-synuclein associated disease spectrum.
