Implication

Cross-cohort EEG study reveals two distinct neurobiological subtypes in schizophrenia, highlighting temporoparietal circuit disruptions that predict symptom severity.

Key Points

To identify reproducible neurobiological subtypes of schizophrenia using source-localized, high-density resting-state EEG functional connectivity patterns.
Applied a clustering algorithm to source-space power envelope correlations across five frequency bands and two resting conditions.
Assessed subtype stability and generalizability through split-half validation and replication in an independent cohort.
Identified two reproducible schizophrenia subtypes across cohorts: one characterized by pronounced temporoparietal disconnection compared to healthy controls, and another showing relatively preserved functional connectivity.
Functional connectivity features significantly predicted clinical symptom severity specifically within the temporoparietal disconnected subtype.
