Exercise & Cognitive Training

Status Completed

Clinical Trial Summary

The purpose of this study is to evaluate the potential benefits of combining cognitive remediation and exercise in improving cognitive functioning and response to psychiatric rehabilitation.

Clinical Trial Description

Impaired cognitive functioning is a common feature of schizophrenia and other serious mental illnesses that is related to poorer psychosocial functioning and less benefit from psychiatric rehabilitation. Research shows that cognitive remediation for persons with serious mental illness improves cognitive functioning and response to psychiatric rehabilitation. There is also evidence that physical activity such as aerobic exercise confers a benefit to cognitive functioning in both clinical and general population samples. The cognitive benefit of exercise is hypothesized to be the result of enhanced brain-derived neurotrophic factor (BDNF; a protein that promotes plasticity, reduces degeneration, and stimulates nerve cell survival). However, the potential synergistic effects of cognitive remediation and exercise on cognitive functioning have not been investigated in persons with serious mental illness. This pilot randomized controlled trial will evaluate the impact of adding a peer run exercise program to a standardized cognitive remediation program on cognitive functioning in 30 people with schizophrenia, schizoaffective disorder or bipolar disorder. All study participants will receive a 10-week cognitive remediation program shown in previous research to improve cognitive functioning. One-half (N = 15) of the participants will also receive a peer-led exercise program designed to promote cardiovascular fitness. The primary research questions addressed are: 1) Does the addition of the exercise program to cognitive remediation lead to greater improvements in cognitive functioning than cognitive remediation alone?, and, 2) Are improvements in cognitive functioning mediated (explained) by exercise-induced increases in BDNF? The results of this pilot study will inform the design of a larger, more definitive trial to evaluate the potential benefits of combining cognitive remediation and exercise in improving cognitive functioning and response to psychiatric rehabilitation. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
