Improving Cognition Via Exercise in Schizophrenia

Not Recruiting

Trial ID: NCT03270098


People with schizophrenia display a broad range of cognitive impairments that have been identified as major determinants of poor functioning and disability. Also, people with schizophrenia are at increased risk for suicide, with approximately 40-50% of individuals attempting to take their own lives during their lifetime. The goal of the proposed study is to examine the impact of remote exercise training on cognition, suicide risk, daily functioning, and biomarkers of cognitive change and suicidality in people with schizophrenia.
