Brief Summary

Cognitive symptoms of schizophrenia interfere with daily life-from managing self-care, to more complex tasks like taking medications and living independently. Unfortunately, these cognitive symptoms are not corrected by 'standard of care' treatments (antipsychotic medications), although some schizophrenia patients may experience modest clinical and cognitive benefits from cognitive remediation. To enhance the clinical impact of cognitive remediation and other rehabilitative interventions for Veterans living with chronic psychosis, this study will develop novel brain-based tools to help identify those Veterans who are most likely to benefit from pro-cognitive therapies. These studies may advance predictive algorithms that improve functional outcomes and life quality in Veterans with schizophrenia.

Outcome Measures

Primary Outcomes (1)

  • 1-week psychometric reliability of Aperiodic Spectral Biomarkers (neurophysiologic biomarker)

    Estimates of aperiodic activity will be calculated from electroencephalography recordings collected at baseline (Day 1) and approximately 7 days later.

    Approximately 7 days

Secondary Outcomes (5)

  • Cognitive training performance

    Day 1/ Baseline

  • Cognition

  • Symptoms

  • Functioning

Study Arms (3)

Biomarker Optimization - Patients

Veterans currently enrolled for healthcare services at the VA San Diego Healthcare System who have a diagnosis of a chronic psychotic disorder (e.g., schizophrenia or schizoaffective disorder).

Other: Neurophysiologic Biomarker Assessments

Biomarker Optimization - Healthy Comparison Subjects

Veterans currently enrolled for healthcare services at the VA San Diego Healthcare System who have no history of mental illness.

Other: Neurophysiologic Biomarker Assessments

Biomarker Validation in Chronic Psychotic Disorders

Veterans currently enrolled for healthcare services at the VA San Diego Healthcare System with a diagnosis of a chronic psychotic disorder (e.g., schizophrenia or schizoaffective disorder).

Other: Neurophysiologic Biomarker Assessments

Study Population

Veterans who are enrolled in and/or receiving healthcare services at the VA San Diego Healthcare System.

You may qualify if:

  • Have a DSM-5 diagnosis of a chronic psychotic disorder (e.g., schizophrenia, schizoaffective disorder, or delusional disorder); or b) are in good general mental and physical health (i.e., no active mental health condition).
