The concept of psychogenic psychosis was introduced by Wimmer in 1916 and subsequently extended by Strömgren in the mid twentieth century. It typically describes a polymorphic psychotic episode of abrupt onset and which follows a trauma or stressful life situation. The duration of the episode is usually brief and remission occurs ad integrum. In recent decades, the notion has fallen into disuse in clinical psychiatry and international classifications. This could be due to a general improvement in living conditions, with less exposure to traumatic situations.

We intend to study the characteristics of psychogenic psychosis in immigrants. We believe that the condition could be observed better in this population, given their greater vulnerability to trauma. For this purpose, we chose a sample of Romanian patients, who nevertheless have considerable cultural affinity with the Spanish population.

We collected the clinical and biographical data of four cases of psychogenic psychosis admitted to our clinic between 2012 and 2015.

Four Romanian women aged 25 to 42 were diagnosed with psychogenic psychosis in this period. Mean length of hospitalization was 5, 0 days. All patients reported familiar or occupational stress prior to the onset of symptoms. Psychotic symptoms remitted quickly with low doses of medication, despite being initially intense.

Reported cases fit remarkably well with the original description of Wimmer. The concept of psychogenic psychosis, along with similar brief psychotic entities, could be useful in describing the psychopathology derived from new social models and crises.
