Cerebrospinal fluid monoamine metabolites in boys with attention-deficit hyperactivity disorder.

Cerebrospinal fluid (CSF), plasma, and urinary monoamine metabolites were determined for 29 boys, aged 6-12, with attention-deficit hyperactivity disorder (ADHD). Levels of CSF 5-hydroxyindoleacetic acid (5-HIAA), homovanillic acid (HVA), and 3-methoxy-4-hydroxyphenylglycol (MHPG), the metabolites of serotonin, dopamine, and norepinephrine, respectively, correlated significantly with behavioral measures of aggression and impulsivity/hyperactivity. However, these correlations were in the unexpected direction; for example, CSF 5-HIAA correlated positively with the Brown-Goodwin Lifetime History of Aggression Scale. HVA in CSF was positively correlated with several measures of hyperactivity. The replicability of these findings, as well as possible socioenvironmental effects, and the predictive value of CSF monoamines in prepubertal hyperactivity are the subjects of ongoing study.
