This study aimed to identify the cerebral blood flow (CBF) in patients with general paralysis (GP).
Three-dimensional pseudo-continuous arterial spin labeling (3D-pCASL) imaging was performed to measure the CBF in twenty patients with GP and twenty healthy subjects(NC). CBF was normalized to reduce variations among subjects. CBF was compared between the groups.
Compared with the healthy subjects, the patients with GP exhibited increased CBF in the frontal lobe, temporal lobe, insular lobe, limbic lobe, and parietal lobe(all P<0.05). There was no difference in CBF of the occipital lobe between the GP group and the NC group(all P>0.05).
Our results suggest that the patients with GP may exhibit regional increased CBF, which may be one of the pathogenesis of general paralysis.
