HCP Early Psychosis Release 1.1

HCP Early Psychosis Release 1.1 Released on 06/16/2021

HCP-Early Psychosis Release 1.1 data is now available in the NIMH Data Archive (NDA). HCP-EP is a study of subjects ages 16-35 focused specifically on early psychosis, both affective and non-affective, within the first five years of the initial onset of psychotic symptoms. This time period is important as it is when there are fewer confounds such as prolonged medication exposure and chronicity, and it is also a time period where early intervention strategies may be most effective, before irreversible brain alterations take place, which likely begin early in the course of illness.

The HCP-Early Psychosis Release 1.1 includes: 

  • unprocessed structural MRI, resting state fMRI, and diffusion MRI data for 183 subjects (34 affective and 91 non-affective psychotic patients, plus 58 matched healthy controls)
  • minimally preprocessed structural MRI data for 169 subjects (33 affective and 80 non-affective psychotic patients, plus 56 matched healthy controls)
  • clinical and behavioral data for 252 released subjects (with corrections for a minority of subjects noted in the 1.1 Release Change Log document) 

The full release dataset (all available imaging + behavioral data) is available on the Connectomes Related to Human Disease (CRHD) Featured Datasets query page on NDA as a single shared package (1.3 TB, OPTION ONE), or as an unprocessed imaging + behavioral package (1.0 TB, OPTION ONE), or can be filtered by modality, processing level, and subject GUID to create a custom package of a subset of the data (OPTION TWO).
