520 | a ObjectivesCognitive decline is common in Parkinson's disease (PD), but the underlying mechanisms for this complication are incompletely understood. Genotypes affecting dopamine transmission may be of importance. This study investigates whether genotypes associated with reduced prefrontal dopaminergic tone and/or reduced dopamine D2-receptor availability (Catechol-O-methyltransferase [COMT] Val(158)Met genotype and DRD2 (CT)-T-957 genotype) affect the development of cognitive deficits in PD. Materials and methodsOne hundred and 34 patients with idiopathic PD, participating in a regional, population-based study of incident parkinsonism, underwent genotyping. After extensive baseline investigations (including imaging and biomarker analyses), the patients were followed prospectively during 6-10 years with neuropsychological evaluations, covering six cognitive domains. Cognitive decline (defined as the incidence of either Parkinson's disease mild cognitive impairment [PD-MCI] or dementia [PDD], diagnosed according to published criteria and blinded to genotype) was studied as the primary outcome. ResultsBoth genotypes affected cognition, as shown by Cox proportional hazards models. While the COMT(158)Val/Val genotype conferred an increased risk of mild cognitive impairment in patients with normal cognition at baseline (hazard ratio: 2.13, P=.023), the DRD2(957)T/T genotype conferred an overall increased risk of PD dementia (hazard ratio: 3.22, P<.001). The poorer cognitive performance in DRD2(957)T/T carriers with PD occurred mainly in episodic memory and attention. ConclusionsThe results favor the hypothesis that dopamine deficiency in PD not only relate to mild cognitive deficits in frontostriatal functions, but also to a decline in memory and attention. This could indicate that dopamine deficiency impairs a wide network of brain areas. | |
