The relationship between psychotic motivation and the genesis of medico-legal acts is well documented in the literature. Delirium and hallucinations, in particular, have been widely reported in this context.

The aim was to identify socio-demographic, clinical, and criminological profile of patients hospitalized for forensic acts committed in psychotic context.

We conducted a descriptive retrospective study, including 7 patients committing a forensic act in psychotic context, selected among all patients hospitalized after a judgement of dismissal (Tunisian law), in psychiatry department, Hedi Chaker university hospital, Sfax, Tunisia. Socio-demographic and clinical data were collected through patients’ observations.

The mean age was 37.7 years. Sex-ratio (M/F) was 6. The criminological act was an attack in 57.1% and homicide in 42.9% of cases. It was committed on the outside in 42.9% of cases. The tool was a bladed weapon in all cases. The victim was a family member in 71.4% of cases. The context was a delirium in 71.4% (theme: 80% persecution, 20% jealousy; mechanism: 40% hallucinatory, 60% interpretative) and hallucinations in 42.9% of cases. Among our patients, 57.1% were indifferent and 28.6% regretted the act. Psychiatric diagnosis was: schizophrenia 57.1%; delusional disorder 28.5% and brief psychotic disorder 14.2%. Personality disorder was reported in 28.6% of patients.

The acting out in a psychotic moment in patients with mental illness remains the most formidable event, causing sometimes the problem of criminal liability. Control of attendance at psychotherapy and psychotropic treatment are preventive and curative necessary measures to avoid crossing the dangerous acts.
