CSF 5‐HIAA Predicts Suicide Risk After Attempted Suicide
Abstract
Suicide risk after attempted suicide, as predicted by cerebrospinal fluid (CSF) monoamine metabolite concentrations, was studied in a sample of 92 psychiatric mood disorder inpatients admitted shortly after attempting suicide. The potential of the serotonin metabolite 5‐hydroxyindoleacetic acid (5‐HIAA) in the CSF to predict suicide risk within the first year after attempted suicide was studied by means of survival analysis after median split sub‐grouping. Eleven patients (12%) committed suicide within 1 year after attempted suicide. Eight of these belonged to the below‐the‐median (< 87 nM) CSF 5‐HIAA subgroup, that is, the suicide risk was 17% as compared with 7% among those with above‐the‐median CSF 5‐HIAA. The cumulative number of survived patient‐months during the first year after attempted suicide was significantly lower in the low CSF 5‐HIAA subgroup. It was concluded that low CSF 5‐HIAA predicts short‐range suicide risk after attempted suicide in mood disorder psychiatric inpatients. These findings lend further support to the serotonin hypothesis of suicide risk.

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.
