Little is known about the relative contributions of multisystem degenerative processes across the spectrum of pre-demented cognitive decline in Parkinson disease (PD). To investigate the relative frequency of caudate nucleus dopaminergic and forebrain cholinergic deficits across a spectrum of cognitively impaired PD subjects in order to explore their relative individual and combined contributions to cognitive impairment in PD. Cross-sectional study. Academic movement disorders clinic. A predominantly non-demented cohort of 143 PD subjects, mean age 65.5±7.4 years, mean Hoehn and Yahr stage 2.4±0.6. Binary classification of [11C]PMP acetylcholinesterase and caudate nucleus [11C]DTBZ monoaminergic PET imaging based on normative data. The frequency of significant degenerative processes based on normative values was determined for consecutive intervals of cognitive impairment ranging from no or minimal (Z>−0.5) to more severe cognitive impairment (Z≤ −2). Across the spectrum ranging from minimal (Z>−0.5) to more severe global cognitive impairment scores (Z≤ −2), caudate nucleus dopaminergic denervation was relatively frequent in those with minimal or no cognitive changes (51.1%) and increased in subjects with more severe cognitive impairments (χ2=12.8, P=0.012). Cortical cholinergic denervation frequency increased monotonically with increasing cognitive impairment from 24.7% (Z>−0.5) to 85.7% (Z≤ −2; χ2=23.2, P=0.0001). 87.0% of subjects with neocortical cholinergic deficits had caudate nucleus dopaminergic deficits. Multiple regression analysis (model F=7.51, P<0.0001) showed both independent cognitive predictions for caudate nucleus dopaminergic (F=7.25, P=0.008) and cortical cholinergic (F=7.50, P=0.007) degenerations and also interaction effects (F=5.40, P=0.022). Cortical cholinergic denervation is a major neurodegeneration associated with progressive declines across the spectrum of cognitive impairment in PD and typically occurs in the context of significant caudate nucleus dopaminergic denervation. Our findings imply that dopaminergic and cholinergic degenerations exhibit both independent and interactive contributions to cognitive impairment in PD.
