Figure 1
Distribution of both Parkinson’s disease patients with mild cognitive impairment (PD-MCI, black bars) and without (PD-noMCI, white bars) by use of varying diagnostic criteria. Cognitive impairment was chosen to be present in less than , or of healthy controls in at least one or two tests per cognitive domain. This demonstrates that the frequency of PD-MCI was highly influenced by the selection of the cut-off values.
