Area of Science:

  • Neuroscience and Cognitive Science
  • Digital Health and Medical Technology
  • Psychiatry and Behavioral Medicine

Background:

  • Cognitive impairment is a significant, persistent deficit in schizophrenia, impacting social functioning and quality of life.
  • Traditional cognitive assessments have limitations in validity and engagement.
  • Virtual reality (VR) serious games and machine learning (ML) present potential for immersive and data-driven cognitive evaluation.

Purpose of the Study:

  • To assess the efficacy of the VR serious game
  • Fruit Pioneer
  • in evaluating cognitive function in stable schizophrenia.
  • To verify the correlation between VR-based cognitive metrics and the Brief Cognitive Assessment Tool for Schizophrenia (B-CATS).
  • To test the discriminative capacity of ML models in classifying schizophrenia patients using VR data.

Main Methods:

  • A prospective cohort study involving 39 patients with stable schizophrenia and 64 healthy controls (HCs).
  • Utilized the VR serious game
  • Fruit Pioneer
  • and standard B-CATS assessments (DSST, TMT A/B, Animal Fluency).
  • Employed logistic regression and support vector machine (SVM) models for classification based on VR behavioral metrics.

Main Results:

  • Schizophrenia patients exhibited significantly poorer performance on B-CATS and VR game metrics compared to HCs (P<.001).
  • VR metrics demonstrated correlations with B-CATS scores in the schizophrenia group.
  • The SVM model achieved an average area under the curve (AUC) of 0.874, effectively classifying patients and HCs.

Conclusions:

  • The integration of VR serious games and ML provides an effective method for cognitive assessment in stable schizophrenia.
  • This approach offers a scalable, engaging, and valid alternative to traditional cognitive tests.
  • The system holds potential for long-term cognitive monitoring and personalized rehabilitation strategies in clinical practice.
