Abstract
We examined the correlations between cerebrospinal fluid (CSF) concentrations of homovanillic acid (HVA) and 5-hydroxyindole acetic acid (5-HIAA) and imaging assessment scores, using 123I-Ioflupane SPECT and 123I-MIBG myocardial scintigraphy in 23 drug naïve PD patients. The CSF 5-HIAA concentration correlated with the H/M ratio of the delayed image (r = 0.458, p < 0.05) and the washout rate (r = - 0.642, p < 0.01) of 123I-MIBG myocardial scintigraphy. These correlations suggest some unclarified pathophysiological links between the central serotonergic and cardiac sympathetic systems.Entities:
