[Biological approach to adolescent suicide].
The high rating of suicide attempts and suicide in the general population and among adolescents justifies a lot of research studies, aiming to better define the genetic and biologic factors. The most relevant model and the most admitted is the role of serotonin which at low concentration in the brain causes more violent suicides or suicidal behaviors, as well as more aggressiveness and impulsiveness. It is not excluded that variations linked to the age could determine, among other factors, specific suicidal behaviors related to the adolescence.
