Posterior parietooccipital hypometabolism may differentiate mild cognitive impairment from dementia in Parkinsons disease
European Journal of Nuclear Medicine & Molecular Imaging, 08/16/2012
Garcia–Garcia D et al. – Parkinsons disease (PD) patients with mild cognitive impairment (MCI) exhibited hypometabolism in several cortical regions compared with controls, and in the frontal and parietal regions compared with cognitively normal patients. Hypometabolism was higher in patients with dementia than in those with MCI, mainly in the posterior cortical areas where it was correlated with visuospatial, memory and executive functions.
