CSF amine metabolites in depression.
The amine metabolites, namely homovanillic acid (HVA) and 5-hydroxy indoleacetic acid (5-HIAA) were measured in cerebrospinal fluid (CSF) of depressives (n = 30) and controls (n = 30). Depressed patients had significantly lower HVA levels than controls. No significant differences were noted between the two groups in 5-HIAA levels. However, the differences between the groups for the CSF HVA/5-HIAA ratio were larger than those for the CSF HVA alone (p less than 0.01 versus p less than 0.025, respectively). HVA levels correlated positively with monoamine oxidase activity and adenosine deaminase activity.
