Study Details

Brief summary:

This longitudinal, observational study aims to assess whether the characteristics of a novel blood peripheral biomarker can serve as indicators for depression and schizophrenia in patients at the Royal Columbian Hospital Psychiatric Clinics. The study will evaluate whether changes in these biomarker characteristics can help distinguish between depressed patients who do or do not respond to treatment and between individuals experiencing a single psychotic episode and those at risk of progressing to schizophrenia. To achieve this, blood samples and standardized mental health assessments will be collected across three study visits from up to 500 participants, grouped into two study arms based on their diagnosis: Depression (DEP) or Psychosis/Schizophrenia (PSY).
