Brief summary
Establishment of a patient library for patients who have had a first psychotic episode and who have an "at risk" status for psychotic disorder (GRD, APS, BLIPS group) or a psychosis threshold during CAARMS administration. Samples are taken on inclusion, at 2 years, and if relapse or significant clinical event within 5 years of inclusion, on 250 patients for 10 years.
Detailed description
The constitution of this patient library will include results of clinical tests carried out in current practice, neurocognitive tests, blood samples, audio recordings, clinical follow-up, urine samples, fecal samples, brain imaging, EEG.
Interventions
OTHERBlood samples (36 mL) + fecal samples + hair sample
Blood samples at inclusion, 2 years later and/or if relapse, fecal samples at inclusion and every years for 5 years, hair sample at inclusion

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| CAARMS (Comprehensive assessment of at-risk mental states) score. | 5 years | The test will determine the mental state of the patient : * "Not at risk of psychosis" * "At risk of psychosis" * "Psychosis threshold exceeded" It is organized into 7 clinical dimensions: 1) positive symptoms 2) cognitive changes: attention / concentration 3) emotional disturbance 4) negative symptoms 5) behavioral change 6) physical and motor changes 7) general psychopathology. Each category is scored between 0 and 6 depending on the level of intensity, frequency and duration of each symptom. In order to determine if a subject meets the UHR criteria for CAARMS, only the first category (positive symptoms) and its four subscales are used according to a scoring algorithm. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| CAARMS sub-assemblies | 5 years | If the patient is classified at risk of psychosis, the test will classify this risk into one of the three following categories : trait and state risk factor group, APS (attenuated psychotic symptoms) group, BLIPS (Brief, Limited or Intermittent Psychotic Symptoms) group. |
