Suicide is a major public health issue in the West, where it is among the top 1 0 causes of death. Throughout world, suicide accounts for about 1 million deaths per year, Inhibitors,research,lifescience,medical ie, 1 death every 40 seconds, according to the World Health Organization,1 and constitutes

a heavy familial, social, and economic burden. Some data concerning suicide are of major interest. First, despite effort in prevention, suicide rates do not appear be decreasing (Figure 1)1 and, in many industrialized countries, the number of people dying through suicide is significantly higher than the number of people dying in automobile accidents. Second, suicide Inhibitors,research,lifescience,medical rates

in adolescents and young adults increased in the last two or three decades, and in many countries suicide mortality rates are the third, or even the second, cause of death among young people. Figure 1 Progression of global suicide rates between 1950 and 1995.1 In view of these data, much effort, has been Inhibitors,research,lifescience,medical made to study the biology of suicide, and a central serotonergic dysfunction is possibly the most studied biological parameter. Vandetanib hypothyroidism Initial in vivo evidence comes from a study showing a lower concentration of acid 5-hydroxyindoleacetic acid (5-HI A A) in the cerebrospinal fluid (CSF) of depressed suicidal patients compared with depressed nonsuicidal patients.2 Many Cilengitide have further confirmed this result, not only in depression but also in schizophrenia and personality disorder,3 showing that lower 5-HI AA CSF concentration is associated with suicidal behavior regardless of psychiatric diagnosis. Neuroendocrine studies A limitation of CSF studies is that they do not address the question of whether overall serotonergic transmission in the brain is decreased, since it is primarily a metabolic measure; furthermore, these studies are rather invasive.
