Abstract

Background Serotonin abnormalities have been reported in the brain of suicide victims. Evidence of a serotonin deficiency in suicide attempters is less consistent. We hypothesized that a serotonin deficiency may be present in suicide attempters whose attempt behavior more closely approximates completed suicide.Method Sixty-seven (67) drug-free depressed inpatients (46 suicide attempters, 21 nonattempters) underwent research clinical assessments and a lumbar puncture. Cerebrospinal fluid (CSF) monoamine metabolites were assayed. Degree of medical damage and intent of the most recent suicide attempt were rated.Results CSF amine metabolites did not differentiate suicide attempters as a group from nonattempters. However, reduced serotonergic activity, as indicated by lower levels of CSF-5-hydroxyindoleacetic acid (5-HIAA) was associated with a history of planned suicide attempts and with suicide attempts that resulted in greater medical damage. Other monoamine metabolites did not correlate with seriousness of suicidal behavior, except for low CSF homovanillic acid and higher medical damage. No correlation was found with violent method.Conclusions Planned and more medically damaging suicide attempts appear to be associated specifically with low serotonergic activity and, therefore, resemble completed suicide both behaviorally and biochemically. It remains to be determined whether low levels of CSF 5-HIAA can predict greater medical damage in future suicide attempts.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
