About the dataset

Primary description: First-episode psychosis cohort

PAFIP is an early psychosis research and clinical intervention program based at the University Hospital Marqués de Valdecilla in Santander, Spain. It focuses on first-episode psychosis (FEP), especially non-affective psychoses such as schizophrenia spectrum disorders in people with their first psychotic episode.

The study is part of the PHENOM consortium. For more information, see: https://doi.org/10.1038/s41380-023-02069-0 and https://doi.org/10.1093/brain/awaa025. The PHENOM (Psychosis Heterogeneity Evaluated Via Dimensional Neuroimaging) consortium is an international consortium pooling MRI and clinical data across several institutions world-wide. The focus on the consortium is to study the use of machine learning and MRI as a means for deriving personalized imaging signatures of schizophrenia, and of predicting future clinical progression. An associated goal is to use state of the art weakly supervised machine learning methods to dissect neuroanatomical heterogeneity in psychosis. In addition to offering healthy control subjects at younger ages, this consortium helps establish imaging signatures of psychosis into NiChart.
