title: Cortisol and Hippocampal Volume as Predictors of Active Suicidal Behavior in Major Depressive Disorder: Case Report.
abstract: BACKGROUND
  Suicide is frequently encountered in patients suffering from major depressive disorder (MDD). Since only a third of treated depressed patients are able to achieve remission, in the last few years, new theories have been proposed to better understand the mechanism of this illness. Our paper analyzes the interrelation between cortisol as a marker of neuroendocrine theory as a response to stress, and hippocampal volume subfields in depression as a marker of neurogenesis and neuroplasticity theory.
  
  
  METHODS
  Here we present the case of a 52-year-old male patient with known history of MDD, who died as a result of completed suicide by hanging. The patient had been recently discharged from a psychiatric clinic, after being hospitalized for a major depressive episode (MDE). The result of the autopsy, medical records, laboratory analysis and a magnetic resonance image (MRI) of the patient were analyzed. Both the right and left volumes of the hippocampus were found to be smaller when compared to normal values reported in the literature. The morning level of cortisol was higher than the normal value.
  
  
  CONCLUSIONS
  In a depressed patient with an acute stressful event, high levels of cortisol associated with decreased volume of the hippocampus could represent predictors for an increased risk of suicide.
