Table 3 The association between CSF serotonin, CSF Dopamine levels, and impulsivity

From: Fibroblast growth factor 21 associating with serotonin and dopamine in the cerebrospinal fluid predicts impulsivity in healthy subjects

Variables BIS total scores BIS nonPlanning BIS motor BIS attention
r p r p r p r p
CSF serotonin (pg/ml) −0.261 0.003 −0.131 0.151 −0.324  < 0.001 −0.152 0.092

  1. Partial correlations were used to analyze the relationship between impulsivity and CSF serotonin or dopamine with the year and education year as covariates. FGF, fibroblast growth factor; BIS, Barratt Impulsiveness Scale.
