OBJECTIVE: This study compared the nature and magnitude of the
relationship between aggression and CSF 5-hydroxyindoleacetic acid (5-
HIAA) concentration with that between aggression and the prolactin response
to d-fenfluramine challenge in human subjects. METHOD: The Life History of
Aggression assessment scores of 24 subjects with personality disorders were
compared with their lumbar CSF 5-HIAA concentrations and with their
prolactin responses to d-fenfluramine challenge. RESULTS: Aggression was
significantly and inversely correlated with prolactin responses to
d-fenfluramine challenge but not with lumbar CSF 5-HIAA concentrations in
these subjects. CONCLUSIONS: Prolactin response to d-fenfluramine may be
more sensitive than lumbar CSF 5-HIAA concentration in detecting a
relationship between aggression and central serotonin activity in
noncriminally violent human subjects.
