About

An acute psychotic episode is a severe psychiatric syndrome which might occur in different psychiatric diagnoses.

The outcome prediction of relapse rate of a psychotic episode within a certain time frame is difficult and depends on many factors. More and better predictors are required to improve the outcome prediction in order to adjust therapy and follow-up if patients suffer from this acute disease.

Copeptin, a surrogate marker for vasopressin, has been proven helpful in the prediction of the outcome in serious somatic diseases. Additionally, a rise of copeptin due to psychological stress was shown.

The aim of this study is to investigate the association of the neuroendocrine biomarker copeptin and the prediction of the onset of psychotic episode within one year.

Full description

An acute psychotic episode is a severe psychiatric syndrome characterised by symptoms like delusions, hallucinations, and perceptual disturbances. A psychotic episode might occur in different psychiatric diagnoses, such as schizophrenia spectrum disorders and affective disorders (depression and bipolar).

The outcome prediction of relapse rate of a psychotic episode within a certain time frame is difficult and depends on many factors. More and better predictors are required to improve the outcome prediction in order to adjust therapy and follow-up if patients suffer from this acute disease.

Copeptin, a surrogate marker for vasopressin, has been proven helpful in the prediction of the outcome in serious somatic diseases such as stroke, myocardial infarction, and pneumonia. Additionally, a rise of copeptin due to psychological stress was shown.

Some studies have shown an increase in vasopressin levels during acute psychosis, no study has been performed using copeptin.

The aim of this study is to investigate the association of the neuroendocrine biomarker copeptin and the prediction of the onset of psychotic episode within one year.
