[Psychophysiology of suicide in prison: a contribution in terms of prevention].

Suicide in detention environment is a phenomenon that affects both prisoners and operators, especially prison service. Currently, in terms of suicide prevention, the interest is shifting from an etiology essentially endogenous to exogenous factors, seeing as the criticality of system has its origin in the lack of knowledge of the "detained person". This work neglects statistics and detection models to look at all those behaviors that are part of suicide, although the suicidal act is not genuine. This view allows to identify areas of risk and it is not just for have a look over "the death event". Aware that no definition is enough to shed light on this phenomenon where subjectivity is elusive, we must always bear in mind the behaviors that precede it and exogenous and endogenous factors. To better understand the phenomenon of suicide in prison it is necessary to be aware of the action that a "totalizing institution" has on the individual.
