Megjegyzések:	Dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD) are characterizedby the presence of ?-synuclein-containing Lewy bodies and Lewy neurites.However, both dementias also show variable degrees of Alzheimer's disease (AD) pathology(senile plaques and neurofibrillary tangles), particularly in areas of the cortex associatedwith higher cognitive functions. This study investigates the contribution of theindividual and combined pathologies in determining the rate of cognitive decline. Cortical?-synuclein, phosphorylated tau (phosphotau) and A? plaque pathology in 34 PDD and 55DLB patients was assessed semi-quantitatively in four regions of the neocortex. The declinein cognition, assessed by Mini Mental State Examination, correlated positively with thecortical ?-synuclein load. Patients also had varying degrees of senile A? plaque andphosphotau pathology. Regression analyses pointed to a combined pathology (A? plaqueplus phosphotau plus ?-synuclein-positive features), particularly in the prefrontal cortex(BA9) and temporal lobe neocortex with the superior and middle temporal gyrus (BA21,22), being a major determining factor in the development of dementia. Thus, cognitivedecline in Lewy body dementias is not a consequence of ?-synuclein-induced neurodegenerationalone but senile plaque and phosphorylated tau pathology also contribute tothe overall deficits.
