BACKGROUND Studies suggest that the dopaminergic system is involved in the pathogenesis of major depression, Axis II disorders, and suicidal behavior. Depressed suicide attempters constitute a heterogenous group and important differences may exist between depressed suicide attempters with or without Axis II disorders. Therefore, we compared demographic and(More)
1. In completed suicides, studies of brain regions and CSF indicate a dysfunction of the serotonergic system. 2. In suicidal patients, regardless of diagnoses, analyses of monoamine metabolites in lumbar CSF reveal decreased concentrations of the serotonin metabolite 5-HIAA. 3. In depressed suicidal patients, both low CSF 5-HIAA and low concentrations of(More)
Brain and cerebrospinal fluid (CSF) levels of homovanillic acid (HVA) and 5-hydroxyindoleacetic acid (5-HIAA) were simultaneously measured in 48 individuals at autopsy. Concentrations of 5-HIAA and HVA in the cerebral cortex were positively correlated with their levels in the CSF for the same individual. Additionally a positive correlation was observed(More)
CSF findings distinguished 12 elderly depressed patients who attempted suicide from nine depressed patients who did not and from seven normal control subjects. Psychosocial factors and measures of psychopathology did not differentiate suicidal from nonsuicidal patients. Biochemical factors may be important in evaluating suicide risk in the elderly.
Chemokines constitute a class of small inflammatory proteins that control the chemotaxis of leukocytes. They are also present in the central nervous system (CNS) and contribute to diverse physiological functions, such as the regulation of cell migration, axonal growth and neuronal survival. It is to date not known whether chemokines in the CNS are affected(More)
Emerging evidence suggests that inflammation has a key role in depression and suicidal behavior. The kynurenine pathway is involved in neuroinflammation and regulates glutamate neurotransmission. In the cerebrospinal fluid (CSF) of suicidal patients, levels of inflammatory cytokines and the kynurenine metabolite quinolinic acid (QUIN), an(More)
