Correlations among the PSD-EEG, striatal
[18F]FDOPA PET/CT uptake ratio and
neuropsychological parameters
Almost all of the PSD-EEG parameters significantly negatively correlated
with the [18F]FDOPA PET/CT uptake ratio in the
putamen (p < 0.05; Table 2), excluding only the PSD-EEG
theta band of the C21 (SMA) and D10 (M1) (p > 0.05;
Table 2). The significant negative correlations between PSD-EEG and
[18F]FDOPA PET/CT uptake ratio in the caudate
nucleus were found for the PSD-EEG of the: (i) lower-alpha band of the
C21 (SMA) and D05 (PFC), (ii) maximal peak of the C21 (SMA) and D10
(M1), as well as for (iii) theta band of the D05 (PFC) (p< 0.05; Table 2).
Almost all the PDS-EEG parameters positively significantly correlated
with the TMT-A and TMT-B (p < 0.05; Table 2), excluding
only correlations of the lower-alpha band and maximal peak of the D10
(M1) with TMT-A (p > 0.05; Table 2). Furthermore,
the PSD-EEG theta band of the C21 (SMA) and D05 (PFC) was positively
significantly correlated with the ST-II (p < 0.05;
Table 2).
Moreover, the [18F]FDOPA PET/CT uptake ratio in
the putamen and caudate nucleus negatively significantly correlated with
the TMT-B, as well as the caudate nuclei
[18F]FDOPA PET/CT uptake ratio negatively
significantly correlated with the TMT-A (p < 0.05;
Table 2).
