Cerebrospinal fluid 5-hydroxyindoleacetic acid (5-HIAA) and homovanillic acid (HVA) measurements have been collected over six years from 275 drug-free, recently hospitalized psychiatric patients, almost exclusively females. In accord with other observations from various countries, patients who had attempted suicide shortly before admission had significantly lower mean CSF 5-HIAA concentration and this was particularly true for those using violent methods. This finding could be replicated in five subsequent samples of patients evaluated separately and using different assay procedures, and proved to be independent of the clinical diagnoses. CSF HVA also showed similar tendencies but it had much larger variance with respect to suicide attempts and therefore fell short of statistical significance. In two patient populations CSF calcium and magnesium measurements have been obtained. CSF calcium did not prove to be related to either suicidal behavior or the diagnosis of major depression; on the other hand, CSF magnesium was found to be significantly lower in the suicide attempters and also correlated with CSF 5-HIAA. Nonsuicidal depressives had comparable CSF calcium and magnesium levels to the controls.
