Recent studies in the neurobiology of schizophrenia highlighted the role of neuropsychoendocrine activations as a consequence of psychostress followed by the activation of the HPA axis with an excess of endogenous cortisol. The relation endogenous cortisol–glutamatergic hyperactivation enhances the excito-toxic mechanisms and the cortical-subcortical alterations in schizophrenia.

We conducted a retrospective study on 40 patients, with ages between 25 and 55 years, admitted in the university clinic of Craiova between January 1, 2015 and December 31, 2015 for paranoid schizophrenia according to ICD-10 criteria and with positive history of psychotrauma and physical abuse in childhood and adolescence.

The frequency of psychotraumas, social stress and physical abuse in our group was significantly higher in women (63.33%), in patients with urban residence (80.00%) and age group 36–45 years (46.67). There was a pattern of residual defectuality reflected by positive symptoms (83.33%), alcohol abuse (80.00%), aggressive behavior (66.67%) and suicide attempts (30.00%). The poor course with minimal social functioning (GAFS < 40; 36.67%) was correlated with a high number of relapses and hospitalizations (> 9 hospitalizations; 43.33%), cognitive deficit (MMSE < 23; 76.67%). The psychosocial factors involved in the pathogenesis and course of schizophrenia were social stress (60.00%), physical abuse in childhood and adolescence (20.00%) and psychotraumas (20.00%).

Psychotrauma and physical abuse in childhood and adolescence and during the course of paranoid schizophrenia constitute a risk factor for a poor outcome with cognitive deterioration, aggressive and suicidal behavior that call for prophylactic measures and qualified psycho-social interventions associated to the pharmacological treatments.
