Relationships between concentrations of cerebrospinal fluid (CSF) kynurenic acid (KYNA) and suicidal behavior were evaluated in 59 patients with psychosis after 22 years of follow-up. Three patients died from suicide and nine patients had a history of attempted suicide. Patients with attempted suicide had significantly lower concentrations of CSF KYNA.
